Does Hot Weather Affect Type 1 Diabetes

Managing Diabetes In The Heat

Managing Diabetes In The Heat

How to keep your cool during the hottest time of year. Did you know that people who have diabetes—both type 1 and type 2—feel the heat more than people who don’t have diabetes? Some reasons why: Certain diabetes complications, such as damage to blood vessels and nerves, can affect your sweat glands so your body can’t cool as effectively. That can lead to heat exhaustion and heat stroke, which is a medical emergency. People with diabetes get dehydrated (lose too much water from their bodies) more quickly. Not drinking enough liquids can raise blood sugar, and high blood sugar can make you urinate more, causing dehydration. Some commonly used medicines like diuretics (“water pills” to treat high blood pressure) can dehydrate you, too. High temperatures can change how your body uses insulin. You may need to test your blood sugar more often and adjust your insulin dose and what you eat and drink. Drink plenty of water. Test your blood sugar often. Keep medicines, supplies, and equipment out of the heat. Stay inside in air-conditioning when it’s hottest. Wear loose, light clothing. Make a plan in case you lose power. Have a go-bag ready for emergencies. It’s the Heat and the Humidity Even when it doesn’t seem very hot outside, the combination of heat and humidity (moisture in the air) can be dangerous. When sweat evaporates (dries) on your skin, it removes heat and cools you. It’s harder to stay cool in high humidity because sweat can’t evaporate as well. Whether you’re working out or just hanging out, it’s a good idea to check the heat index—a measurement that combines temperature and humidity. Take steps to stay cool (see sidebar) when it reaches 80°F in the shade with 40% humidity or above. Important to know: The heat index can be up to 15°F Continue reading >>

Tips For Managing Diabetes in the Summer Heat People with diabetes not only need to know about how to manage their blood sugar levels, how their medications work,and what their blood tests mean but also how to plan and prevent damage from warm temperaturesto diabetes supplies, equipment, and blood sugar levels themselves. Beyond Type 1 is a non-profit founded in 2015 byJuliet de Baubigny, Nick Jonas , Sarah Lucas and Sam Talbot. The group works to educate others on type 1 diabetes as well as share resources and support for people living with type 1 diabetes. All of their money raised goes to support efforts to educate, advocate, and cure type 1 diabetes. The CEO and co-founder of Beyond Type 1, Sarah Lucas, has generouslyprovided some informationon the subject of managing diabetes in the summer heat. DD: Managing type 1 diabetes becomes a bit more complicated in the summer when we have to take the heat into account. What worries do people with type 1 encounter due to the heat? Warmer weather introduces a range of concerns for those with diabetes. Warmer weather conditions may cause heat exhaustion, hypoglycemia and a change in blood glucose levels. People with diabetes are also concerned with the effectiveness of medical supplies like blood glucose meters, test strips, and insulin. What are some things people with type 1 diabetes can do to stay safe when temperatures are high? Staying hydrated and monitoring blood sugar levels in the heat is essential. Drinking plenty of fluids like water is best, but non-caffeinated herbal beverages are good options as well. Taking extra steps to prevent dehydration is crucial as it can cause blood glucose malfunction.It is also recommended to avoid highly caffeinated or sodium filled beverages as those beverages can result in dehydra Continue reading >>

Diabetes In Hot Weather — 12 Things To Know

Diabetes In Hot Weather — 12 Things To Know

To date, 2016 has been the hottest year ever, and it’s getting hotter. From now on, coping with heat will be an important part of managing diabetes. Some knowledge that might help you: 1. High body temperatures can lower blood sugar. Mayo Clinic writers Nancy Klobassa Davidson, RN, and Peggy Moreland, RN, CDE, say you should check your sugars more often in the hot weather. 2. Sunburn can raise blood sugar. The Mayo Clinic advises wearing a good sunscreen, sunglasses, and a hat while out in the sun. 3. Warm skin absorbs insulin faster, while dehydrated skin absorbs insulin more slowly. The closer you can keep your injection site to normal temperature and hydration, the better. 4. Dehydration from sweating can raise blood sugar and can lead to heat exhaustion. According to the Cleveland Clinic, people with diabetes are more likely than others to be admitted to hospitals for dehydration and heat exhaustion, and to die from it. High glucose levels lead to urinating more, which increases risk for dehydration. This may be especially true if you’re on an SGLT-2 inhibitor drug. Keep drinking water with a bit of salt if you are blessed to live in an area where water is available. Have a bottle with you and don’t wait until you’re thirsty to drink. Learn to check yourself for dehydration by pinching up some skin on your arm and letting it go. It should snap right back into place. If it goes more slowly, you are getting dehydrated. Don’t drink alcohol or caffeine in super-hot weather, as they are dehydrating. 5. Heat can damage insulin, other medications, and test strips. The Joslin Clinic advises people to keep their insulin cool, but not on ice. If you take medicines with you while you’re away from home, get a cooler bag to keep your medicines and test strips in.

Heat And Type 1 Diabetes

Heat And Type 1 Diabetes

Note: This article is part of our Daily Life library of resources. To learn more about the many things that affect your health and daily management of Type 1, visit here. Whether experiencing hot summer temperatures or a tropical vacation, it is important for everyone to beware of the heat – and the various effects that it can have on our bodies. Have you ever noticed your blood sugar either spiking or dropping rapidly in severe temperatures? Many people with Type 1 diabetes run into this issue and have been baffled as to why. Heat may have much more of an impact on your blood glucose levels than you realized! Keeping a close eye on your BG becomes even more important when in areas with higher temperatures. Here are some possible explanations to the heat’s role in blood sugar fluctuations, and some factors to keep in mind while enjoying your summer fun in the sun with Type 1! High blood sugar Heat can spike blood sugar levels easily if we are not properly hydrated. When the body is dehydrated, blood glucose becomes more concentrated due to the decrease in blood flow through the kidneys. This makes it much more difficult for the kidneys to remove any excess glucose from urine. How to fix it? Adjust insulin dosages as instructed by a medical professional, and most importantly drink plenty of water! Low blood sugar Blood glucose levels have been known to plummet in the heat – especially when combined with exercise. Why is this? Heat can cause the body’s blood vessels to expand, which in turn can speed up insulin absorption and potentially lead to hypoglycemia. This can be made worse when exercising due to the increased blood flow to certain areas, especially if insulin is injected in the legs. Also consider that hot tubs/jacuzzis or hot showers/baths can have the s Continue reading >>

Heat And Diabetes

Heat And Diabetes

Living with diabetes blog Diabetes research is turning up new information on diabetes and diabetes management all the time. In 2009, I wrote a blog about the effects of heat on blood glucose control if you have diabetes. I mentioned, then, that heat doesn't have a direct effect on your blood glucose, but that heat can lead to changes in your daily routine which, in turn, can affect your blood glucose. Later research, published in September 2010 by researchers at Mayo Clinic, Scottsdale, Ariz., suggests, additionally, that some Arizonans with diabetes have considerable gaps in their "heat awareness." This lack of awareness led to actions such as waiting until temperatures were quite high (above 101 F, or 38.3 C) before taking precautions against the heat and leaving medications and supplies at home rather than risk exposing them to the heat — meaning not having the supplies to manage diabetes while away from home. Sweating is an important means of cooling the body in hot weather, and the ability to sweat can be affected in some people with diabetes. Other studies have shown an increase in emergency room visits, in those who have diabetes, when temperatures are high. Diabetes equipment and medications can also be affected by heat. Tips for managing diabetes in warm temperatures remain the same: Avoid sunburn, it can stress your body and can raise your blood glucose. Wear a good sunscreen, sunglasses and hat when out in the sun. Drink plenty of water to avoid dehydration. Carry a bottle of water with you on walks, etc. Exercise and do more strenuous activities in the early or later hours of the day when the temperatures are cooler and the sun is not at its peak. Check blood sugar levels frequently, since they may fluctuate. Remember, extreme temperature changes can have Continue reading >>

Hot Weather And How It Affects Diabetes

Hot Weather And How It Affects Diabetes

Diabetes Qld Pharmacist The hot summer ahead may have many impacts on diabetes management for your clients. Oral hypoglycaemic medications, insulin and blood glucose monitoring strips are affected by the heat so may impact people living with diabetes and their care. As the temperature rises, so may the levels of counter regulatory hormones in your clients living with diabetes. Counter regulatory hormones such as catecholamines, growth hormone, cortisol and glucagon may potentially elevate blood glucose levels, impacting glucose management. Higher temperatures may also increase the risk of hypoglycaemia, especially for people living with type 1 diabetes. This may be due to an increase in absorption rate of insulin from the subcutaneous layers. In a study, the absorption of rapid-acting insulin injected subcutaneously was compared at room temperatures of 20°C and 35°C. During a 4-hour period, the rate of insulin disappearance at 35°C was 50 per cent to 60 per cent greater than at 20°C ambient temperature. (1) Another factor to consider which increases risk in high temperatures among people with diabetes is possible abnormalities of the thermoregulatory capacity caused by autonomic neuropathy. Autonomic neuropathy affects several organ systems, with undesirable outcomes such as hypoglycaemia unawareness and cardiovascular dysfunction. Heat stress intensifies the issues resulting from autonomic neuropathy by affecting body homeostasis (balance within the body), especially for cardiovascular and glycaemia states. (2) Oral medications have a shelf life which represents the time that the active ingredient retains an acceptable potency. At the expiry date, the potency of the medication must be above 90 per cent of the original active ingredient content. Medications are all Continue reading >>

Diabetes And Heat Intolerance

Diabetes And Heat Intolerance

I have mentioned this subject quite some time ago now, and have read a bit about it. Apparently 60-70% of diabetic Americans suffer with some form of nerve damage (neuropathy), and this is a cause of heat intolerance in diabetics as the sweat glands are involved. Inefficient sweat glands cause the body to fail to cool down. Symptoms are mainly lack of perspiration, but the opposite can also be a symptom (too much sweat). My search that uncovered this was on the body's inability to regulate body temperature. Definitely neuropathy seems to be behind it, but when I mention it to my doctors, even the endo, they just want to know about my feet. Neuropathy affects any nerves in the body, including major organs, glands, and skin. Not just feet! My question is, does anyone have any medical experience with this subject, and medical support, back-up, anything useful at all? Do others experience heat intolerance (and/or cold intolerance), the feeling that your body can't seem to regulate body temperature? Any remarks, information, links, etc. will be much appreciated. In order to become what you are to be, you must learn, first, to be what you are. D.D. Family Getting much harder to control Good point try a google on autonomic neuropathy it affects many things regualted normally by the body. In the last 2 yrs my heart no longer knows I am not exercising and goes to 160 plus on my pulse rate its autonomic neuropathy. Thank you. I will google it and see what I can find. It is frustrating, knowing something, but not being able to generate even a discussion with a doctor about it. My feet do suffer. I cannot wear a closed in shoe as they overheat and burn to the point of being unable to walk. But I am overall intolerant to heat, not just my feet. My head even burns, skin itches so ba Continue reading >>

Ask The Expert: Summer Heat And Diabetes Control

Ask The Expert: Summer Heat And Diabetes Control

Question: How can the summer heat affect diabetes control? Heat, especially extreme heat, is hard for anyone to tolerate. It’s especially hard on people with diabetes. When your body is exposed to heat, you lose more water through sweat, which can dehydrate you. Dehydration increases blood sugar levels. High blood sugar will make you urinate more often, which can dehydrate you even more. To stay hydrated, drink more fluids. You can tell when you’re drinking enough because your urine will be lighter-colored. Heat can affect the way your body absorbs insulin. In hot weather, more blood flows to your skin. When you’re dehydrated, the opposite happens -- less blood flows to the skin. Most types of insulin, especially short-acting insulin, don’t work as well when blood flow is decreased. The heat can affect your medicines. If you leave insulin in a hot car, it will start to degrade. Bring along a cooler to keep insulin at room temperature or below. Heat can also damage test strips, leading to false readings. That’s going to affect your blood sugar management and how much insulin you take. Be careful when you exercise in the heat. Watch for both high and low blood sugar. Your blood sugar can drop if you are on a medication that could cause low blood sugar. Being outside in hot weather and exercising produce similar symptoms, such as sweating and a fast heart rate, so it’s easy to overlook the early symptoms of low blood sugar. That’s why you need to check your blood sugar every hour or two while you exercise. Bring juice, glucose tablets, or glucose gel along for your workout, in case your blood sugar dips. If you take insulin, ask your [doctor] how to adjust your dosage when exercising. Avoid sunburn. It damages your skin and can affect diabetes control. A seri Continue reading >>

Hot Summer Weather May Affect Individuals With Type 1 Diabetes Or Type 2 Diabetes

Hot Summer Weather May Affect Individuals With Type 1 Diabetes Or Type 2 Diabetes

Hot summer weather may affect individuals with type 1 diabetes or type 2 diabetes Exercise is a key component in diabetes management plans, and individuals with type 1 diabetes or type 2 diabetes may be more likely to meet their physical activity goals during the summer months when there is plenty of opportunity to spend time outdoors. However, the hot weather may pose certain risks to individuals with type 1 diabetes or type 2 diabetes. A recent article published by Fox-31 News Online reported that people with type 1 diabetes or type 2 diabetes may be more susceptible to dehydration than those who do not have the disease. The news provider explained that low blood sugar levels may accelerate the rate of dehydration, so it is important for diabetics to stay hydrated throughout the day. Checking your blood sugar is very important because with the extra energy that your body has to use to stay cool, your blood sugar may go down more than it normally would, said pediatrician Cathy Palmier, quoted by the news source. She noted that some individuals with type 1 diabetes or type 2 diabetes have an impaired ability to sweat, which may make them more likely to be affected by even moderate heat. Warm weather may also affect diabetes medications, the news organization stated. Temperatures above 86 degrees may cause abnormal interactions between ingredients in diabetes treatments, which may alter their efficacy. The American Diabetes Association recommends that people with type 1 diabetes or type 2 diabetes who require insulin should store their supplies at room temperature. Bottles of insulin that are not in use can be kept in the refrigerator, but they should be taken out long enough to warm up before they are put to use, the organization says. This is because chilled insulin m Continue reading >>

Body Temperature Regulation In Diabetes

Body Temperature Regulation In Diabetes

Go to: Introduction Diabetes mellitus, commonly known as diabetes, refers to a group of metabolic disorders which are associated with an impaired ability to regulate glycemia. Type 1 and type 2 diabetes are the most prevalent forms of the disease representing ~10 and ~90% of cases, respectively.1 Type 1 diabetes was formerly known as juvenile diabetes due to its common presentation in children and adolescents, and is characterized by the endocrine pancreas ceasing to produce insulin following the immune-mediated destruction of β-islet cells.2 Therefore, management of type 1 diabetes always requires exogenous delivery of insulin. Although the causes of type 1 diabetes remain to be elucidated, it is probably caused by a combination of genetic predisposition (with >40 loci known to affect susceptibility)3 and various environmental factors including stress and viruses.4 On the other hand, type 2 diabetes is most often diagnosed in adults and typically involves a combination of insulin resistance and relative (rather than absolute) deficiency of insulin.5 While the causes of type 2 diabetes are also incompletely understood, a plethora of studies have found associations with excessive abdominal adiposity,6 sedentary lifestyle, and poor dietary habits7 along with genetic factors. In contrast to type 1, type 2 diabetes may be treated in several ways including non-insulin pharmaceuticals, lifestyle modifications as well as exogenous insulin administration. Diabetes is becoming a worldwide public health issue, with the global prevalence in 2014 estimated at 9% among adults.8 By 2035, the International Diabetes Federation has projected a prevalence of 592 million cases with an additional ~175 million going undiagnosed.9 In North America alone, ~7% (2.5 million) of Canadian adults Continue reading >>

The Claim: Diabetes Makes You Sensitive To Heat

The Claim: Diabetes Makes You Sensitive To Heat

THE FACTS Summer can be uncomfortable for anyone. But for people with diabetes, the heat and humidity can be particularly hazardous. One of the complications of diabetes, both Type 1 and Type 2, is an impaired ability to adjust to rises in temperature, which can cause dangerous increases in body temperature during the summer. The underlying problem, nerve damage, occurs in 60 to 70 percent of Americans with diabetes; it can affect nearly every organ in the body, including sweat glands. When nerve damage keeps the sweat glands from working properly, the body fails to cool down as the mercury rises. In one small study, scientists compared diabetic patients and a group of healthy control subjects as they were exposed to increasing temperatures. The subjects were hooked up to devices that measured skin temperature, core temperature and sweat rates. As temperatures rose, the control subjects’ perspiration rates increased proportionately; their core temperatures stayed constant. “For subjects with diabetes, sweat seemed to plateau irrespective of an alarming rise in core temperature,” the scientists wrote. “The diabetic subjects’ generalized inability to sweat across the body had a profound effect on core temperature.” Research by the Mayo Clinic in Arizona shows that diabetic patients have higher rates of adverse events — like hospitalizations, dehydration and death — in the heat. Yet a survey by the clinic found that many were unaware of the greater risk and the need for special precautions. THE BOTTOM LINE People with diabetes are particularly vulnerable to hot weather.

Diabetes And Hot Weather - Staying Safe In The Heat

Diabetes And Hot Weather - Staying Safe In The Heat

Diabetes and Hot Weather - Staying Safe in the Heat There are hypo and hyper risks in hot weather Whether you are going on holiday or simply spending some time outdoors in the heat, high temperatures and the close humidity currently sweeping the UK do have an influence for people with long term conditions such as diabetes. This may partly be explained by increased activity in hot weather, but there is no doubt that the heat does affect some people with diabetes in other ways. What problems can hot weather cause for people with diabetes? Dehydration can be an issue in hot weather, and higher blood glucose levels can further increase this risk. People with diabetes may need to increase their intake of fluids in hot weather, drinking water regularly through the day. One of the major concerns regarding diabetes and hot weather is the risk of blood sugar levels rising or falling and causing hypoglycemia or hyperglycemia . What are the hypo risks from hot weather? Hot weather can increase the risk of hypoglycemia for those on blood glucose lowering medication. The Joslin Diabetes Centre notes that the bodys metabolism is higher in hot and humid weather which can lead to an increased chance of hypoglycemia. Hypos may be slightly harder to spot in hot weather. Dont be tempted to disregard hypo symptoms , such as sweating and tiredness, as a result of hot weather as it could be a sign of hypoglycemia. Take extra care when driving and test your blood sugar before and after each journey and stop regularly to check your blood sugar if taking longer journeys. To prevent hypos, be prepared to test your blood glucose more often, particularly if taking part in physical activity in hot weather. Keep a source of fasting carbohydrate, such as glucose tablets, to hand. To help treat hypos Continue reading >>

Summer Heat Is A Risk To Diabetes Patients

Summer Heat Is A Risk To Diabetes Patients

The results weren't all bad. "Most patients incorporated appropriate personal protective measures such as staying indoors, drinking additional fluids on schedule, applying sunscreen, and wearing protective clothing," says Adrienne A. Nassar, MD, a third year resident at Mayo Clinic Arizona, who presented the findings at ENDO 2010 in San Diego, the annual meeting of the Endocrine Society. But the respondents fell short in other ways. For instance, one in five waited until temperatures were over 100 degrees before taking precautions, Nassar said at a news conference And 23% began drinking fluids when they got thirsty -- typically too late to prevent dehydration effectively. Many left their medications and monitoring equipment at home during a heat wave. Nassar and her colleagues analyzed responses of 152 people with diabetes living in Phoenix, where the average July temperature is 107 F. On average, the patients were 64 years old, 85% had type 2 diabetes, and 77% were on insulin injections or pumps. Their blood glucose test results on the hemoglobin A1c tests were on average 7.9%, although the goal for those with diabetes is 7%. While many respondents protected their medication in the heat by carrying it in a cooler, 37% left medication or supplies at home. "This is quite concerning,'' Nassar says, "because they would not have the means to check their blood sugar" if they became faint, for instance. While most respondents, 72%, knew about the effect of heat on insulin, just 40% said they had gotten information from their health care providers about the ill effects of high temperature on oral medications, 41% on glucose monitors, and 38% on glucose monitoring strips. The point at which respondents said they would take protective measures varies. Nassar can't pinpoint an ex Continue reading >>

How Hot And Cold Weather Affects Your Blood Sugar

How Hot And Cold Weather Affects Your Blood Sugar

Find a weather-proof location to exercise all year round. Working out in your living room or local gym, or even just walking your local mall are all good options. When temperatures start to get out of control, so can your blood sugar. Both hot and cold weather extremes can affect your testing equipment and your medications, and have a negative impact on your body’s ability to produce and use insulin. Research shows that when it’s hot out, more people with diabetes end up in the ER and are hospitalized because of heat illness. The number of deaths in diabetes patients due to heat illness also increases in summer. Low temperatures can be an issue for people with diabetes as well. But you don’t have to let the environment have the upper hand. Taking a few smart precautions can help you outsmart Mother Nature. Here are the adjustments to make depending on where you live and the weather forecast. 6 Tips to Survive the Summer Heat Take these steps to keep your diabetes under control when the temperature soars: Stay hydrated. Lori Roust, MD, an endocrinologist at the Mayo Clinic in Arizona, explains, “The problem is that in the heat, people tend to get dehydrated easily. When you’re dehydrated, you have higher concentrations of blood sugar because less blood flows through your kidneys. With less blood, your kidneys don’t work as efficiently to clear out any excess glucose (blood sugar) from your urine.” When it’s hot, be sure to drink plenty of water or sugar-free drinks. Don’t wait until you are thirsty to replenish fluids. Store your medications properly. High summer temps can affect your diabetes medications, glucose meter, and diabetes test strips. “When it’s hot out, it’s easy for insulin and other drugs to become degraded,” Dr. Roust says. Be su Continue reading >>

Type 1 Diabetes And Hot Weather

Type 1 Diabetes And Hot Weather

I cant believe it took me so long to think about this but does anyone know if hot weather effects our bg? See I live in the Arizona desert, its a dry heat and our winter is the temperature of most places summer (the other night it was 80,at night lol). I spend most of my days in the AC and its winter so I dont have to worry too much yet. However in summer it gets up to 125, its so hot that even a breeze feels like a blow dryer on a hot setting. Im becoming more active again since finding out and im worried that the extreme weather might cause an extreme change in my bg. I really want to be able to go off-roading, or have fun at the river but heat stroke is very real here and im worried itll lower my bg by a lot. Does anyone know what I can expect? Thanks in advance for any insights Yes! It will impact your BG. My mom (T1 for 40 years) says heat can make her levels increase or decrease - seemingly at random. I have heard that dehydration from sweating too much can make your BG increase, so its just something to keep an eye out for. In my short time at a T1D, I dont have too much experience in this area, but I have considered buying something to keep my insulin cool when its too hot. That seems like I have looked at the water activated cooling packs (Frio brand I think), and I may buy one when we get closer to summer. Yes Jeanne @JeanneMS weather, changes in temperature, barometric pressure change can all affect your blood sugar; and as seasons change [YES, even in Florida seasons change] your insulin needs MAY change. when I encountered this 40 or so years ago and reported it to the doctor he in effect told me I was dreaming; since then we have done a few studies and find this to be true. What happens, I believe, is that your body absorbs and utilizes insulin at differi Continue reading >>
