By 1FLYCHIK Latest Reply2013-03-01 15:31:51 -0600 Hi Everyone. I wanted to see if anyone knows or has experienced this. I am traveling to Peru in 2 weeks to do some charity work and I am wondering if the high altitude there will affect my levels? If so, how did you manage them or what precautions did you take??? Everything else effects it, so why not high altitude?! Then the question becomes does low altitude send it the other way? I live and work at 1300-1400 feet, so where does high altitude start? May the Lord bless you and keep you and your team be safe from harm and disease. When I traveled to New Mexico a while back I found that my levels were elevated when we were camping. I was exercising more, eating better and less, but my levels still seemed to climb the mountains with me. Not really bad, but I would say I struggled with an additional 40 points of average. I go up to the Grand Canyon every year for a week for work, and the altitude there (8800 feet) doesn't mess with my levels at all! I do, however, get alititude sickness badly after my 2nd day up there, which is no fun at all, and makes it hard to work! Remember to drink lots and lots of water-it is supposed to help with that, and enjoy your time there. Sounds like you will be doing good things and enjoying your visit as well :) Continue reading >>

How Many Factors Actually Affect Blood Glucose?

How Many Factors Actually Affect Blood Glucose?

A printable, colorful PDF version of this article can be found here. twitter summary: Adam identifies at least 22 things that affect blood glucose, including food, medication, activity, biological, & environmental factors. short summary: As patients, we tend to blame ourselves for out of range blood sugars – after all, the equation to “good diabetes management” is supposedly simple (eating, exercise, medication). But have you ever done everything right and still had a glucose that was too high or too low? In this article, I look into the wide variety of things that can actually affect blood glucose - at least 22! – including food, medication, activity, and both biological and environmental factors. The bottom line is that diabetes is very complicated, and for even the most educated and diligent patients, it’s nearly impossible to keep track of everything that affects blood glucose. So when you see an out-of-range glucose value, don’t judge yourself – use it as information to make better decisions. As a patient, I always fall into the trap of thinking I’m at fault for out of range blood sugars. By taking my medication, monitoring my blood glucose, watching what I eat, and exercising, I would like to have perfect in-range values all the time. But after 13 years of type 1 diabetes, I’ve learned it’s just not that simple. There are all kinds of factors that affect blood glucose, many of which are impossible to control, remember, or even account for. Based on personal experience, conversations with experts, and scientific research, here’s a non-exhaustive list of 22 factors that can affect blood glucose. They are separated into five areas – Food, Medication, Activity, Biological factors, and Environmental factors. I’ve provided arrows to show the ge Continue reading >>

High Altitude's Never-ending Love For Hypoglycemia - Diabetes Daily Grind | Real Life Diabetes Podcastdiabetes Daily Grind | Real Life Diabetes Podcast

High Altitudes Never-Ending Love For Hypoglycemia On trail to Mt. St. Vrain in the Rocky Mountain National Park 2 days. 8 low blood sugars. The numbers tellthestory:the higher you climb, the lower you fall.We all enjoy good paradox, right? Am I a mountain man? No, partlybecause it takes me 3 weeks to grow a 5 oclock shadow, and I spend the majority of my life at sea level. Oxygen likes to have a good time at sea level. It glides into my lungs with relative ease, slips into my blood, and enjoys homeostasis. At high elevations, especially those approaching 10,000 feet, oxygen gets depressed. It hides out with its cats and starts crocheting. In response to this hermitism, the heart works double time. Being that the heart is a relatively selfish organ in its oxygen (and subsequently glucose) use, it singlehandedly elevates our metabolism, by 10-20% at my best guess. So whats the end result for the insulin-deficient? Low blood sugars. When you toss in a bit of strenuoushiking on a non-acclimated body, youve got yourself the perfect recipe for consistent hypos. Its now day 3. Im about to set out on a hike. Just scarfed down a healthy sized breakfast and Im defying all logic with a no bolus policy. Why? Well, because its hard to bounce back from a low just 30 minutes into a hike. Ill check every 30 minutes, avoid complete diabetes management ignorance, and bask in some mountain air.

Diabetes In The Altitude

Diabetes In The Altitude

I spent the last week in Crested Butte, Colorado, for what has now become an annual family ski trip. The place we were staying was at an elevation of 7,000-something feet. Of course, my mom told us to drink plenty of water and take saltwater nose drops to flush the system out. All of this is fine and dandy, but I wondered what, if any, effect does altitude have on diabetes ? I know that my lungs were working a bit harder to adapt to the drier air. I was out of breath after climbing two sets of stairs. I also found that I needed a snack every couple of hours on the slopes, but this makes sense, as snow skiing is a workout. I would leave the condo every morning with my glucometer, NovoLog FlexPen, needles, and about four granola bars to eat on the lifts in between runs in case I felt a little low. The tricky part here was that it was more of a guessing game, because my glucometer could easily get too cold at the top of the mountain to check my blood glucose. Anyone have any tips on checking your blood glucose outside in really cold weather? This year had exceptionally good weather for spring skiing and we celebrated my niece Sara Reevess fifth birthday. I really enjoy spending time with her and watching her grow up. We skied together and she followed right in my tracks. There is nothing cuter than a five-year-old with pigtails on skis. After a long day on the slopes, we got in the hot tub with everyone for a few minutes and she felt like a big girl. One morning, before breakfast, I was in the kitchen drawing up my insulin , and she was at the bar having cereal. I asked her if she wanted to give me a shot, and she said no. Then she said something that surprised me. She said one of her best friends, Molly, has diabetes. Maybe its just that it was coming from an adorable fi Continue reading >>

Effect Of High Altitude On Blood Glucose Meter Performance.

Effect Of High Altitude On Blood Glucose Meter Performance.

Abstract Participation in high-altitude wilderness activities may expose persons to extreme environmental conditions, and for those with diabetes mellitus, euglycemia is important to ensure safe travel. We conducted a field assessment of the precision and accuracy of seven commonly used blood glucose meters while mountaineering on Mount Rainier, located in Washington State (elevation 14,410 ft). At various elevations each climber-subject used the randomly assigned device to measure the glucose level of capillary blood and three different concentrations of standardized control solutions, and a venous sample was also collected for later glucose analysis. Ordinary least squares regression was used to assess the effect of elevation and of other environmental potential covariates on the precision and accuracy of blood glucose meters. Elevation affects glucometer precision (p = 0.08), but becomes less significant (p = 0.21) when adjusted for temperature and relative humidity. The overall effect of elevation was to underestimate glucose levels by approximately 1-2% (unadjusted) for each 1,000 ft gain in elevation. Blood glucose meter accuracy was affected by elevation (p = 0.03), temperature (p < 0.01), and relative humidity (p = 0.04) after adjustment for the other variables. The interaction between elevation and relative humidity had a meaningful but not statistically significant effect on accuracy (p = 0.07). Thus, elevation, temperature, and relative humidity affect blood glucose meter performance, and elevated glucose levels are more greatly underestimated at higher elevations. Further research will help to identify which blood glucose meters are best suited for specific environments. Continue reading >>

Asknadia: Why High Altitudes Will Give You High Blood Sugars

Asknadia: Why High Altitudes Will Give You High Blood Sugars

AskNadia: Why High Altitudes Will Give You High Blood Sugars Why do my BGs run high when I hike in higher altitudes? When you exercise in elevations your body is accustomed to, chances are you have a good idea of how your blood sugar will respond. Exercising in high altitudes such as hiking generally, reduces your oxygen intake and stresses your body. Stress releases cortisol, the stress hormone, causing blood sugars to go up. Additionally, research demonstartes that carbohydrate metabolism may be comprised at higher altitudes causing insulin resistance. On the flip side, If you get dehydrated from hiking you will experience similar symptoms to hypoglycemia; shortness of breath, nausea, and rapid heart beats. Blood Glucose Meters, CGMs & Insulin Pumps Medical devices can vary in their accuracy at higher elevations. If one device is less accurate, it will be confusing to isolate which one is impacting your blood sugar. Calibrate all your devices to affirm their accuracy before you start your trip. This will add anther layer of security to assure your blood sugar readings are within the proper range for your devices. I would also recommend testing your blood sugar before, during and after your hike to give you a baseline on how higher elevations impact your blood sugars, making your return trip less stressful and more predicable. If possible, bring back up diabetes supplies just in case you ascertain accuracy issues with one medical device.

Diabetes And High Altitude: Your Complete Travel Guide

Diabetes And High Altitude: Your Complete Travel Guide

Does altitude affect your diabetes? Some people say yes, some say no. As with many aspects of diabetic care, it depends largely on the individual. What is altitude sickness? Altitude sickness...as defined by Google is... “Illness caused by ascent to high altitude, characterised by hyperventilation, nausea, and exhaustion resulting from shortage of oxygen.” So basically if you are going higher in the world than what you are used to...Then you are likely to experience altitude sickness. It affects everyone differently- I have had people tell me they couldn’t leave their hotel rooms, to people who managed it easily. Everyone is brilliantly unique! Diabetes and altitude sickness is then a whole other ball game. Blood glucose and altitude Does altitude affects blood sugars? Altitude can impact your blood sugars in a variety of ways... 1) Hypoglycemia and altitude The symptoms of altitude sickness are quite similar to those of low blood sugar (hypoglycemia), such as, sickness, feeling light headed & dizzy, actual headaches & out of breath; so it can make it difficult to actually work out whether you are in a hypo or suffering from attitude sickness- this happened quite frequently with myself in Bolivia & Peru, and I would recommend testing your blood sugars even more frequently to make sure you know the difference. 2) Hyperglycemia and altitude Altitude can potentially cause your blood sugars to go high- now I have seen articles argue for and against this, but I will tell you that in my own experience, this is completely true. At high altitude my blood sugars took a turn for the worst and were a lot harder to control. I frequently had high blood sugars for no other logical reason- and when you have the continual symptoms of a high blood sugar, and the symptoms of altitu Continue reading >>

Living At High Altitude Could Reduce Type 2 Diabetes Risk

Living At High Altitude Could Reduce Type 2 Diabetes Risk

Living at high altitude could reduce type 2 diabetes risk Living at high altitude could reduce type 2 diabetes risk Sitting less and walking more could reduce fasting insulin levels by 11 per cent 27 January 2017 People living at higher altitudes have a reduced risk of type 2 diabetes , heart disease and stroke , according to Spanish researchers. Scientists at the University of Navarra suggest that the geographic area in which you live to contribute to the risk of metabolic syndrome. This is the medical term for the combination of high blood sugar , blood pressure and cholesterol , which contributes to a higher risk of type 2 diabetes , heart disease and stroke. "We found that those people living between 457 to 2,297 metres had a lower risk of developing metabolic syndrome than those living at sea level (zero to 121 metres)," said co-senior author and PhD candidate Amaya Lopez-Pascual. Obesity, smoking and sedentary behaviours are among the leading risk factors for metabolic syndrome, but not a lot is known about how our environment could affect this risk. The researchers analysed data from a Spanish project that asked participants to submit their health information twice-yearly since 1999. This data was then used to track the development of metabolic syndrome in relation to the altitude of where participants lived, of whom were initially health at the beginning of the study. It was shown that the higher the altitude where a person lived, the less likely they were to develop metabolic syndrome. This association existed even after analysis of family history. "Living or training at high altitudes or under a simulated hypoxic [oxygen deficient] environment seems to help with heart and lung function, losing weight , and improves insulin sensitivity ," said co-senior author Continue reading >>

How Elevation Affects Your Blood Sugar

How Elevation Affects Your Blood Sugar

If you regularly travel from a sea-level location (such as Miami) to a high-level location (such as Albuquerque or, say, a mountaintop), you might wonder why your blood sugars always read lower at the high elevation. Its not your imagination: Most blood glucose meters use a chemical reaction that requires oxygen from the air to measure blood sugar. At high altitudes, there is less oxygen in the air, which causes the results to be lower. Thus, the results you get may be affected by altitude. If you are traveling to a place with a much different altitude, read the instructions that came with your meter and also the package insert in the strips. You may also call the toll-free 800 number in the package insert, or write to the company that makes the meter to find out whether its readings are affected by altitude. If you spend time on social media, why not get your diabetes tips there also? Lifescript has just launched a dedicated type 2 diabetes Facebook page that will offer diabetes tips, recipes, inspiration and more.

Altitude And Type 1 Diabetes

Altitude And Type 1 Diabetes

As you may already know, travel in general can have a big impact on Type 1 diabetes management. This is typically due to elements such as stress hormones, time change and other shifts in routine that can cause blood sugar levels to behave differently. However, there are other things to consider when taking trips or exploring the outdoors that might not occur to us right away – such as changes in altitude. The most important thing to remember when planning to journey some place at a higher altitude is that nobody is affected the same way, so it is best to be prepared for multiple outcomes. Altitude sickness By far the most common side effect of being at high altitudes is altitude sickness, which can then lead to (or simulate) other symptoms that can affect T1D management. Common symptoms of altitude sickness include: shortness of breath rapid heartbeat nausea exhaustion All of this is due to the decrease in oxygen, but these symptoms are also common when suffering from hypoglycemia (low blood sugar!). So it is important to test blood sugar levels often to distinguish between the two. Blood sugar levels Hypoglycemia – There is no direct evidence that altitude causes low blood sugar, but as previously mentioned, altitude symptoms can feel quite similar. Also, increased exercise (if hiking or walking a lot while in high altitudes), can definitely lead to lows. Hyperglycemia – Traveling, exercising and managing T1D when out in the elements can cause a good deal of stress. Stress hormones lead to high blood sugar. Insulin resistance There have been studies that suggest that higher altitudes can cause insulin resistance due to carbohydrates not being metabolized as effectively. This can be another cause of high blood sugar and it can also lead to ketones/ketoacidosis in Continue reading >>

This topic is now archived and is closed to further replies. Does altitude affect blood sugar readings? A friend called me today to see if I might help find an answer for him. He is 70, diagnosed type II 2 years, fairly well controlled by diet and exercise alone. Normal bgs. fasting 110-125, dropping to 100 before lunch. 2 hr PP normally in the 130's. He watches his carbs carefully. Around 15-25 grams carb at lunch and 10-15 at other meals -- less than 75 day. Problem is he is vacationing in New Mexico at 8700' above sea level -- he lives at 700' in Texas. His blood sugar has gone up very high with little or no change in his diet. Fasting is now 170's and doesn't drop as it usually does. PP after lunch (his largest meal) is also 170's. Lowest he's been since being in NM is 145+/-. His question is does altitude affect bgs, and if so, what can he do to help bring numbers down without meds? (He's not close to medical help where he's vacationing.) I've searched this forum and found nothing. Did find a a 2 year old thread on another forum that indicated bgs in Type 1s can be affected either way by altitudes above 6500', and meters tend to lose accuracy above that elevation also. Does anyone have any other information or personal experience that I can pass along to him as how he can bring his bgs down? I've been vacationing in Utah for the past week, at 9200 feet, and I find that my BGs are running higher than usual, but not hugely. Average for the last 7 days is running 94; 5% higher than the week before. Fastings all in the 90s (and one 101), after a week in the high 80s. My highs are not necessarily higher (only Continue reading >>

Ain't No Mountain High Enough: Managing Diabetes In High Altitudes (part Ii) | Speaking Of Diabetes | From Joslin Diabetes Center

Zack McCune snowboarding in Squaw Valley, California While there are many people who enjoy snowboarding, skiing, and hiking in the mountains, there are others who like push the limits even further. Some consider climbing into the clouds to reach mountaintop summits to be the ultimate test of mind and body. For people managing diabetes, mountain climbing can present even more challenges. In the second installment of our two part series, we take a look at what you need to know when your winter activities involve extreme altitudes. In the U.S., some of the highest ski resort summits are Beaver Creek at 11,440 ft, Vail at 11,570 ft, and Breckenridge at 12,998 ft. But what if youre planning on going even higher? Mount Whitney in California has a 14,505 foot summit, Kilimanjaro is 19,308 feet above Tanzania, and Ojos del Salado is a whopping 22,608ft in the air. Theres a lot more to think about than the cold . At those altitudes its pretty complex in that there are a lot of physiological changes that impact the diabetes, says Jacqueline Shahar , M.Ed., RCEP, CDE, a Certified Diabetes Educator and Manager of Exercise Physiology at Joslin Diabetes Center. Although it hasnt been studied extensively, there have been a few studies monitoring climbers with type 1 diabetes as they ascended steep peaks. Besides being attentive to problems experienced at lower mountain altitudes like decreased temperatures, exacerbated diabetic neuropathy from the cold, and increased risk of low blood sugar from low oxygen and increased physical activity, you also have to be aware of worsening diabetic retinopathy . The increased altitude can worsen the affect diabetes has on your eyes and even cause retinal hemorrhages, so make sure to have a thorough eye exam and an okay from your doctor before emb Continue reading >>

Blood Glucose And Altitude

Blood Glucose And Altitude

I am 72 years old and have had diabetes for 15 years. At sea level in Southern California, with a moderate activity level and normal eating habits, I need between 140 and 150 units of Humalog each day. When I exercise, my blood sugars rise, and I need insulin to come back down. I keep my blood glucose in check by measuring 4 to 6 times per day, and I use both a needle and a pump. I control to between 70 and 110 and have an A1C of 6.2.I currently live in Aspen/Snowmass, Colo., at an altitude of 8,200 feet. Although I do exercise more, my insulin requirement is between 40 and 50 units each day. In addition, when I exercise, my blood sugars drop, so I can only ski or bike starting at an elevated blood sugar level. Quite the opposite from sea level.The dawn phenomenon that I experience requires me to take an additional 15 units of insulin at sea level, but only an additional 6 units when I am at a higher altitude.I have not found an explanation yet for this phenomenon.
