Blood Sugars High In Morning

The Dawn Phenomenon – Why Are Blood Sugars High In The Morning?

The Dawn Phenomenon – Why Are Blood Sugars High In The Morning?

Getting high blood sugars after a period of fasting is often puzzling to those not familiar with the Dawn Phenomenon. Why are blood sugars elevated if you haven’t eaten overnight? This effect is also seen during fasting, even during prolonged fasting. There are two main effects – the Somogyi Effect and the Dawn Phenomenon. Somogyi effect The Somogyi effect is also called reactive hyperglycaemia and happens in type 2 diabetic patients. The blood sugar sometimes drops in reaction to the night time dose of medication. This low blood sugar is dangerous, and in response, the body tries to raise it. Since the patient is asleep, he/she does not feel the hypoglycaemic symptoms of shakiness or tremors or confusion. By the time the patient awakens, the sugar is elevated without a good explanation. The high blood sugar occurs in reaction to the preceding low. This can be diagnosed by checking the blood sugar at 2am or 3am. If it is very low, then this is diagnostic of the Somogy Effect. Dawn phenomenon The Dawn Effect, sometimes also called the Dawn Phenomenon (DP) was first described about 30 years ago. It is estimated to occur in up to 75% of T2D patients although severity varies widely. It occurs both in those treated with insulin and those that are not. The circadian rhythm creates this DP. Just before awakening (around 4am), the body secretes higher levels of growth hormone, cortisol, glucagon and adrenalin. Together, these are called the counter-regulatory hormones. That is, they counter the blood sugar lowering effects of insulin, meaning that they raise blood sugars. The nocturnal surge of growth hormone is considered the primary cause of the DP. These normal circadian hormonal increases prepare our bodies for the day ahead. That is, glucagon tells the liver to start p Continue reading >>

How To Avoid High Morning Blood Sugars

How To Avoid High Morning Blood Sugars

We’ve all been there before. You wake up. Lay in bed for a few before getting your booty up to go kill the workday and accomplish big things. Check your blood sugar. 115 (6.3 mmol/l) stares back at you. You smile to yourself: life is good. Forty minutes later, when you sit down to eat, your CGM gives you a “high” notification, and you’re 180. You have eaten NOTHING. All you’ve done is prepare for the day and prepare food. Now you face the grim potential of chasing your sugars all day long. What the… This isn’t Dawn Phenomenon Many people would blame this rise in blood sugar on dawn phenomenon (DP), which has a similar endpoint, but a different mechanism. Dawn phenomenon is the result of hormones releasing in the body in the early morning – predominantly growth hormone, cortisol, epinephrine, and glucagon – which in turn increase insulin resistance. The current basal insulin from the pump or long-acting injections is no longer enough, and blood sugars rise. That hormonal surge happens around 2am-6am, with most of it occurring in the middle of the night. Let’s say you woke up at 8:30am and aren’t in the “DP zone.” It’s not DP. Then what? Feet on the floor The moment your feet touch the floor as you roll out of bed, you signal to your body, “Hey, I need energy for all the stuff I’m about to do!” Your body recognizes you haven’t eaten in lord knows how many hours. Your body is also lazy smart and wants the most easily accessible source of energy: the liver. The liver is the Wal-Mart for stored energy, since it’s got everything you need. It stores glycogen that can be easily broken down when fasted or needed for activity, AND is the home of gluconeogenesis, a process where protein is broken down to glucose for energy. Guess what? You’r Continue reading >>

Controlling The Dawn Phenomenon

Controlling The Dawn Phenomenon

Do you wake up with a blood glucose level that’s higher than when you went to bed? You might wonder how this could be. Is this “dawn phenomenon” serious, and what can you do about it? Our reader Mishelle commented here, “I don’t eat [much] during the day. [I take metformin morning and night.] My blood sugar is still too high in the morning…sometimes 125–140ish.” How can Mishelle’s glucose levels go up if she didn’t eat anything? She probably has a mild case of dawn phenomenon. Her glucose is going up from sources other than digested food. Some of it is produced by the liver from stored starch and fatty acids. Livers that produce too much glucose are one of the main ways diabetes causes high blood glucose levels. Other organs also produce small amounts of glucose. This is called “gluconeogenesis” for you science freaks out there. Organs do this to keep blood glucose from going too low at night or other times of not eating. From about 2 AM to 8 AM, most people’s bodies produce hormones, including cortisol, glucagon, and epinephrine. All these hormones increase insulin resistance and tell the liver to make more glucose. The idea is to get you enough glucose to get out of bed and start the day. The whole process is apparently started by growth hormones. Everyone has a dawn phenomenon. Otherwise they’d be too weak to get breakfast. But in people without diabetes, insulin levels also increase to handle the extra glucose. People with diabetes can’t increase insulin levels that much, so their early morning blood glucose levels can rise dramatically. Experts disagree on how many people have a dawn phenomenon. Estimates range from 3% to 50% of Type 2s and from 25% to 50% of Type 1s. Is dawn phenomenon a serious problem? It can be serious. According t Continue reading >>

High Blood Glucose Levels Before Breakfast

High Blood Glucose Levels Before Breakfast

Tweet If you are regularly having high sugar levels before breakfast, there are a number of causes which could be the reason for it. Below are some of the more common reasons, including an explanation of how they can cause high sugar levels and what action you may wish to take to tackle the problem. For advice on how to spot high patterns, see our guide to dealing with highs and lows. Too little intermediate or long acting (basal) insulin If you are consistently getting high readings before breakfast, it could be that your long acting (basal) insulin is too low. If you take intermediate insulin (such as NPH insulin), consistently high sugar levels in the morning could be the result of taking too little intermediate insulin at dinner time. Action Consider increasing your dose of long acting or intermediate insulin. If increasing your insulin, do so gradually and test your blood glucose regularly to identify whether your blood glucose is going to low as a result. As always, be prepared to test your blood glucose if you feel the symptoms of hypoglycemia. If you at all unsure of how or whether to adjust your insulin, speak to your diabetes health team who will be able to help you. Be careful if you are considering increasing insulin Make sure your health team are happy for you to adjust your own insulin doses and consult them if you are in any doubt. If you increase your insulin, do so gradually to prevent risking severe hypoglycemia from occurring and test your sugar levels regularly to check low sugar levels are not occurring Having a meal with a delayed spike for dinner Some meals have a delayed spike, that is they can cause a significant rise in blood sugar levels that occurs a number of hours after having eaten. Meals that can typically lead to a delayed increase in bl Continue reading >>

Why Do I Have High Blood Sugar Levels In The Morning?

Why Do I Have High Blood Sugar Levels In The Morning?

Some people experience very high blood sugar levels in the morning. But what implications does this have for a person's health? There are two main causes of high blood sugar in the morning, the dawn phenomenon and the Somogyi effect This article explores these two causes of high blood sugar levels in the morning. It also discusses what risk factors may cause people to experience them and gives practical advice around how to better manage blood sugar levels. Contents of this article: The dawn phenomenon The dawn phenomenon has to do with natural body changes that occur during the sleep cycle: Midnight - 3 a.m. While most people are sleeping, their body has little need for insulin. During this period, however, any insulin that may have been taken during the evening causes the blood sugar levels to drop off drastically. Between 3 - 8 a.m. The body automatically begins to dish out stored sugar (glucose) in preparation for the upcoming day. In addition, hormones that actively reduce the body's sensitivity to insulin are also being released. During this time period, counter-regulatory hormones are being released. This can interfere with insulin, which may lead to a rise in blood sugar. These include growth hormones, such as: cortisol glucagon epinephrine These events are all happening simultaneously as bedtime levels of insulin are beginning to taper off. Each of these events ultimately plays a part in causing blood sugar levels to rise at "dawn" or in the morning. Who the dawn phenomenon affects Although people with diabetes are generally more aware of the dawn phenomenon, it actually happens to everyone. However, it affects people with or without diabetes differently. Typically, people who do not have diabetes tend not to notice these high blood sugar levels in the morning. Continue reading >>

7 Morning Rituals Proven To Lower Morning Blood Sugar Naturally

7 Morning Rituals Proven To Lower Morning Blood Sugar Naturally

If you’re a diabetic, you may find that your blood sugar levels are at their peak in the morning. This is due to the fasting period overnight. It’s common for blood sugar tests to require a period of fasting beforehand to get the best natural levels. You need to get your blood sugar levels down right away. The good news is you don’t necessarily need to rely on medication. While you will want to take medication in the way that your doctor has prescribed, you will still want to follow these seven-morning rituals. It is possible to reverse type II diabetes and focus on a healthier and more natural lifestyle. Even if you’re not a diabetic, you will want to keep your morning blood sugar levels down. Here are the seven must-follow morning rituals that have proven to lower the blood sugar levels on a morning completely naturally. Wait, Why Is Your Blood Sugar Up In the Morning? Why is it that your blood sugar levels will rise overnight? You don’t eat anything, so how can you possibly add any glucose to your system? Well, those who suffer from type II diabetes will find this is most problematic. The body still creates glucose throughout the night. It needs to, whether you’ve eaten something or not. This natural process is called gluconeogenesis, and there is nothing you can do to stop it – nor would you want to. In a healthy person, this process doesn’t cause a major problem. Those with diabetes will find the gluconeogenesis process is increased. That means your body produces more glucose naturally than it would if you were healthy. Let’s not forget that the stress hormone cortisol also plays a part. This increases slowly on a morning until it reaches a peak early in the morning. The cortisol will elevate the blood sugar levels, so you end up with naturally hi Continue reading >>

Managing Morning Blood Sugar Highs: How To Treat The Top 3 Causes

Managing Morning Blood Sugar Highs: How To Treat The Top 3 Causes

A high blood sugar reading first thing in the morning can throw off your whole day — and signal a chronic problem. Despite their best efforts to control their blood sugar levels, some people simply wake up with elevated blood sugar. Starting your day this way isn't just alarming: If it becomes a pattern, high morning readings can make it difficult to achieve your long-term diabetes management goals. Whether you have type 1 or type 2 diabetes, a morning blood sugar high can be due to several causes. But with a little detective work and the help of your diabetes care team, you can isolate the cause and take steps to correct it. Here are three common scenarios: 1. The Dawn Phenomenon This occurs during the night while you're asleep and the body releases stress hormones. This phenomenon usually occurs between 3 a.m. and 8 a.m. and involves growth hormone, cortisol, and adrenaline, which trigger the production and release of glucose from your liver. The end result of this chemical cascade is an increase in blood sugar. “These hormones are designed to get us up and moving in the morning,” says endocrinologist Renee Amori, MD, assistant professor of medicine in the division of endocrinology at the Drexel University College of Medicine in Philadelphia. While everybody experiences these natural changes in hormone levels, in people with diabetes the body may not adjust appropriately. This can lead to higher-than-normal blood sugar at the start of the day. Testing for these elevated first morning blood sugars is one way to diagnose people with type 2 diabetes. 2. The Somogyi Effect High morning readings can also be caused by the Somogyi effect, a rebound response that occurs when the body overcompensates for a low blood sugar reaction at night. If you take blood sugar–lowe Continue reading >>

Blood Sugar: What Causes High Blood Sugar Levels In The Morning

Blood Sugar: What Causes High Blood Sugar Levels In The Morning

There are two reasons why your blood sugar levels may be high in the morning – the dawn phenomenon and the Somogyi effect. The dawn phenomenon is the end result of a combination of natural body changes that occur during the sleep cycle and can be explained as follows: Your body has little need for insulin between about midnight and about 3:00 a.m. (a time when your body is sleeping most soundly). Any insulin taken in the evening causes blood sugar levels to drop sharply during this time. Then, between 3:00 a.m. and 8:00 a.m., your body starts churning out stored glucose (sugar) to prepare for the upcoming day as well as releases hormones that reduce the body's sensitivity to insulin. All of these events happen as your bedtime insulin dose is also wearing off. These events, taken together, cause your body's blood sugar levels to rise in the morning (at "dawn"). A second cause of high blood sugar levels in the morning might be due to the Somogyi effect (named after the doctor who first wrote about it). This condition is also called "rebound hyperglycemia." Although the cascade of events and end result – high blood sugar levels in the morning – is the same as in the dawn phenomenon, the cause is more "man-made" (a result of poor diabetes management) in the Somogyi effect. There are two potential causes. In one scenario, your blood sugar may drop too low in the middle of the night and then your body releases hormones to raise the sugar levels. This could happen if you took too much insulin earlier or if you did not have enough of a bedtime snack. The other scenario is when your dose of long-acting insulin at bedtime is not enough and you wake up with a high morning blood sugar. How is it determined if the dawn phenomenon or Somogyi effect is causing the high blood sug Continue reading >>

Why Is My Blood Sugar High In The Morning?

Why Is My Blood Sugar High In The Morning?

That early morning jump in your blood sugar? It's called the dawn phenomenon or the dawn effect. It usually happens between 2 and 8 a.m. But why? Generally, the normal hormonal changes your body makes in the morning will boost your blood sugar, whether you have diabetes or not. If you don't, your body just makes more insulin to balance everything out. You don't even notice that it's happening. But if you have diabetes, it's different. Since your body doesn't respond to insulin the same as most, your fasting blood sugar reading can go up, even if you follow a strict diet. The boost in sugar is your body's way of making sure you have enough energy to get up and start the day. If you have diabetes, your body may not have enough insulin to counteract these hormones. That disrupts the delicate balance that you work so hard to keep, and your sugar readings can be too high by morning. The effects of the dawn phenomenon can vary from person to person, even from day to day. Some researchers believe the natural overnight release of what are called counter-regulatory hormones -- like growth hormones, cortisol, glucagon and epinephrine -- makes your insulin resistance stronger. This will make your blood sugar go up. You may also have high blood sugar in the morning because: You didn't have enough insulin the night before. You took too much or too little medicine. You ate the wrong snack before bedtime. If the dawn phenomenon affects you, try to: Eat dinner earlier in the evening. Do something active after dinner, like going for a walk. Check with your health care provider about the medicine you’re taking. Eat breakfast. It helps bring your blood sugar back to normal, which tells your body that it's time to rein in the anti-insulin hormones. Eat a snack with some carbohydrates and Continue reading >>

How To Fix High Morning Blood Sugars (dawn Phenomenon)

How To Fix High Morning Blood Sugars (dawn Phenomenon)

There are various possible causes of a high blood sugar level in the morning: The Dawn Phenomenon which is a natural rise in blood sugar due to a surge of hormones secreted at night which trigger your liver to dump sugar into your blood to help prepare you for the day. Having high blood sugar from the night before which continue through the night into the morning. Reactive hyperglycemia which is also called the Somogyi Effect. This is when a low blood sugar in the middle of the night triggers your liver to dump sugar into your blood in an attempt to stabilize your blood sugar. Why Are My Blood Sugars High in the Morning? There is a simple strategy for diagnosing the source of high blood sugars in the morning. Test your blood sugar before bed. Test your blood sugar in the middle of the night. Test your blood sugar in the morning. It takes a little bit of effort, but you only need to do it a few times to diagnose the issue. TheSomogyi Effect is less common than the Dawn Phenomenon, according to an article published by The Polish Journal of Endocrinology. To diagnose either of these phenomena, scientists recommend checking blood sugar levels for several nights specifically between 3 a.m and 5 a.m. or using a continuous glucose monitoring system (CGM). Many healthcare practitioners are now offering the use of a loan CGM for a few days which can be helpful to observe nighttime blood sugar activity. How to Fix High Blood Sugars in the Morning The Dawn Phenomenon refers to a surge of hormones excreted by your body in the early morning hours. These hormones rise each night around the same time to prepare your body to wake. Basically, your body is starting the engine, releasing some fuel, and prepping to go for the day. The Dawn Phenomenon occurs in all humans regardless of whet Continue reading >>

Why Is Blood Sugar High In The Morning?

Why Is Blood Sugar High In The Morning?

Q: Why does my blood sugar go up in the morning when I've eaten right and taken my medicines? A: You don't mention how high your blood glucose levels are rising. But blood glucose will increase after eating, even if you "eat right." The main thing that affects fasting blood glucose is the amount of glucose that the liver releases during the night. In type 2 diabetes, the liver tends to release too much glucose during sleeping hours. The body cannot process all that glucose properly because there isn't enough insulin, and the body resists the action of the insulin that is present. Insulin resistance tends to be more of a factor in the morning. So morning blood glucose levels are often too high. Some people with type 1 have high blood glucose levels in the early morning because of the dawn phenomenon, in which the release of hormones contributes to elevated levels. Or glucose levels may rebound from overnight episodes of hypoglycemia (low blood glucose). Keep testing your blood glucose two hours after your first bite of breakfast and write down what you eat. Then share the results with your health-care provider so you can adjust medication or your meal plan.

Why Is Blood Sugar Highest In The Morning?

Why Is Blood Sugar Highest In The Morning?

Many people with diabetes find that their fasting blood sugar first thing in the morning is the hardest blood sugar to control. In addition, they find that if they eat the same food for breakfast as they do for lunch or dinner they will see a much higher blood sugar number when testing after breakfast than they see at the other meals. The reason for this is a normal alteration in hormones experienced by many people not just people with diabetes. It is called "Dawn Phenomenon." What Causes Dawn Phenomenon? The body prepares for waking up by secreting several different hormones. First, between 4:00 and 6:30 a.m. it secretes cortisol, epinephrine, and norepinephrine. You may recognize these as the hormones involved in the "fight or flight response." In this case, their job is more benign, to give you the energy to get up and moving so you can find the food your body needs for energy. To help you do this, these hormones also raise your blood sugar. After a long night's sleep, the fuel your body turns to to get you going is the glucose stored in the liver. So after these stress hormones are secreted, around 5:30 a.m., plasma glucose rises. In a person with normal blood sugar, insulin will also start to rise at this time but many people with diabetes won't experience the corresponding rise in insulin. So instead of giving their cells a dose of morning energy, all they get is a rise in blood sugar. Not Everyone Experiences Dawn Phenomenon Researchers who have infused different hormones into experimental subjects have found that the trigger for dawn phenomenon is a nocturnal surge in growth hormone. If they block the growth hormone, blood sugars stay flat. This may explain why some people, particularly older people, do not experience a rise in blood sugar first thing in the mor Continue reading >>

Diabetes Forum The Global Diabetes Community Find support, ask questions and share your experiences. Join the community Help! High Blood Sugars in the morning, fine the rest of the day! I am hoping some people might be able to offer some advice. I am 27 and have had diabetes for 25 years. I am usually well controlled (especially in the past 5 years) however for the past few months I have been waking up with high blood sugars each morning. And I mean high- this morning I was 17.2. I take Glargine (split dose am and pm) and then carb count with Humalog during the day. The rest of the day I am absolutely fine, running at between 4 and 6 most of the time. And there seems to be no pattern to the highs. Most mornings I am around 12-15 but sometime I am normal at 5. I tried cutting out desserts, eating earlier, eating later but nothing seems to change. My doctor suggested increasing my Glargine, which I did for a couple of weeks but I was hypoing all over the place so I have gone back to the original dose. Has anyone ever had anything similar? Or does anyone have any advice? I am pretty much up for trying anything right now as I feel so awful when I wake up Yes, I have done the thing where you test every 2 hours through the night - and it seems to be in the last few hours before waking up (I usually get up at 7am). To me this suggests I am running out of insulin in those last few hours, but is there a way to combat that? I am pretty good at rotating my injection sites. I have to admit I am not sleeping great, but I havnt for a number of years and its only in the last few months that this has become an issue! Thanks for your response, I will try rotating my sites abit more to see if it helps I had the same issue for the longest time and my doctor got me one of those devices (c Continue reading >>

The Dawn Effect: Tips For Fixing High Morning Blood Sugars

The Dawn Effect: Tips For Fixing High Morning Blood Sugars

An early morning spike in the blood sugar can be a sign of poorly-controlled diabetes or something called the Dawn Effect. Here's what you can do. The dawn phenomenon sometimes called the dawn effect, is the term given to an early morning spike in the fasting blood sugar in an individual with diabetes. Typically occurring between 2 and 8 AM, it can be frustrating for those who are making every effort to control their blood sugar. Fortunately, the dawn phenomenon can be effectively managed. Why it Happens Everyone—those with or without diabetes—experiences a rise in blood sugar in the early morning. “There is a surge in growth hormone secretion in the early morning and this appears to be the hormone that may be the most responsible for the dawn phenomenon, at least in people with type 1 diabetes,” says Robert Courgi, MD, a hospitalist and endocrinologist at Southside Hospital in Bay Shore, New York. “The dawn phenomenon is apparently not only responsible for a rise in fasting glucose, but it can also account for an exaggerated rise in post-breakfast blood glucose.” Growth hormone, as well as hormones like cortisol, are “get-up hormones that work to get us started on our day,” explains Yan Yan Sally Xie, MD, an endocrinologist at Long Island Jewish Medical Center in New Hyde Park, New York and North Shore University Hospital in Manhasset, New York. “But all these hormones cause glucose levels to rise.” In a person who doesn’t have diabetes, there is sufficient insulin to cope with the blood glucose, or sugar, when it rises, Dr. Courgi says. “But in someone with diabetes, there’s just not enough insulin to control the sugar,” he adds. The pancreas isn’t able to produce insulin as needed, so the blood glucose rises. The Consequences of High Blo Continue reading >>
