In this sense, the Dawn Phenomenon
Dawn phenomenon
The dawn phenomenon, sometimes called the dawn effect, is an early-morning increase in blood sugar which occurs to some extent in all humans, more relevant to people with diabetes. It is different from chronic Somogyi rebound in that dawn phenomenon is not associated with nocturnal hypoglycemia. It is thought to occur due to temporal elevation in serum cortisol, epinephrine and norepinephrine associat…
How to reduce dawn phenomenon naturally?
To address the dawn phenomenon, we need a combination of these factors:
- Slow liver’s morning production of glucose (gluconeogenesis) – Apple Cider Vinegar
- Stimulate better insulin production – Stevia and Apple Cider Vinegar
- Inhibit glucagon – Stevia
- Increase nutrient sensitivity – Stevia
Can non diabetics have the dawn phenomenon?
The dawn phenomenon is more likely to occur in a diabetic than in a non-diabetic. The dawn phenomenon is a consequence of the diurnal variation of the stress hormone called cortisol.
What causes dawn phenomenon?
The causes of Dawn Phenomenon are mostly hormonal: the natural overnight release of counter-regulatory hormones, such as growth hormone, adrenaline, cortisol, epinephrine, and glucagon increases insulin resistance, resulting in higher blood sugar levels overnight and in the morning.
How bad is diabetes?
When people with diabetes consume too many carbs at a time, their blood sugar levels can rise to dangerously high levels. Over time, high levels can damage your body’s nerves and blood vessels, which may set the stage for heart disease, kidney disease, and other serious health conditions.

Does dawn phenomenon happen to everyone?
Everyone experiences the dawn phenomenon to some extent, but most people do not notice it because their insulin response naturally makes the necessary adjustments. In a person with diabetes, this may not happen.
What causes the dawn phenomenon in non diabetics?
Researchers determined that the early morning glucose rise was caused by an increase in the so-called “counterregulatory hormones” cortisol, epinephrine, and norepinephrine. They are called counterregulatory hormones primarily because they “counter” the effects of insulin.
Does dawn phenomenon mean I have diabetes?
The dawn phenomenon happens in people with either type 1 or type 2 diabetes. It's caused by changes in hormones that lead to increases in blood sugar that begin in the early morning hours. Many people that experience the dawn phenomenon won't have any physical symptoms.
Can stress cause dawn phenomenon?
Unlike typical glucose spikes, the dawn effect is not a direct result of eating, stress, or exercise: It's a spontaneous increase in your fasting blood sugar.
Should I worry about the dawn phenomenon?
Those hormones can work against insulin to cause your blood sugar to rise slightly. When this happens, it is known as 'dawn phenomenon. ' In most people, dawn phenomenon is typically harmless because your body creates a small amount of insulin to correct the problem.
How do you beat dawn phenomenon?
Instead of carbohydrate rich foods—like pasta or white rice—resistant starches or proteins may be better night time meals for individuals experiencing the dawn phenomenon. It's also been suggested that night time exercise, as well as early morning exercise has the potential to reduce dawn phenomenon1,13.
What causes blood sugar to rise in non diabetics?
Look out for these surprising triggers that can send your blood sugar soaring: Sunburn—the pain causes stress, and stress increases blood sugar levels. Artificial sweeteners—more research is needed, but some studies show they can raise blood sugar. Coffee—even without sweetener.
Can non diabetic have high blood sugar?
Nondiabetic hyperglycemia means your blood glucose (sugar) level is high even though you do not have diabetes. Hyperglycemia may happen suddenly during a major illness or injury. Or, hyperglycemia may happen over a longer period and be caused by a chronic disease (diabetes type I or II).
Does intermittent fasting help with dawn phenomenon?
Does intermittent fasting aid in this phenomenon? The dawn phenomenon directly associates with insulin sensitivity or production. Improving insulin sensitivity via a low-carb diet and/or intermittent fasting, would lessen the morning fasting blood sugar values. Also, reduce the dawn phenomenon effect.
What time does the dawn phenomenon start?
If you're experiencing the dawn phenomenon, which raises your blood sugar between approximately 3 and 8 a.m., your doctor may recommend that you avoid increasing your long-acting insulin.
What does the dawn phenomenon feel like?
Share on Pinterest Symptoms of the dawn phenomenon include nausea, weakness, and extreme thirst. The dawn phenomenon refers to a rise in blood sugar released by the liver. The release happens as the person's body is preparing to wake for the day. The body normally uses insulin to cope with this rise in blood sugar.
Does metformin reduce dawn phenomenon?
Metformin, an oral diabetes medication commonly prescribed for people with type 2 diabetes, can help slow down the release of glucose from the liver and prevent the dawn phenomenon.
Why does dawn phenomenon occur?
The dawn phenomenon In the early hours of the morning, hormones, including cortisol and growth hormone, signal the liver to boost the production of glucose, which provides energy that helps you wake up. This triggers beta cells in the pancreas to release insulin in order to keep blood glucose levels in check.
Can you have Somogyi effect and not be diabetic?
The dawn effect involves a rise in early morning blood sugar levels. This results from declining levels of insulin and an increase in growth hormones. Everyone experiences higher blood sugar levels in the morning, whether they have diabetes or not.
Which hormone is responsible for dawn phenomenon?
The dawn phenomenon is a normal rise in blood sugar as a person's body prepares to wake up. In the early morning hours, hormones (growth hormone, cortisol, and catecholamines) cause the liver to release large amounts of sugar into the bloodstream.
Why does my blood sugar rise when I haven't eaten anything?
This means that your blood sugar may be high in the morning, even before you eat anything. A few things can cause this surge in blood sugar, including: hormone release early in the morning that increases insulin resistance. insufficient insulin or medication left in your body from the night before.
Why does blood sugar rise in the morning?
It is believed that the rise in blood sugar during the early morning hours is due to the release of glucose from the liver —this can be referred to as a liver dump.
What is the dawn effect?
What is the dawn phenomenon that some people with diabetes experience? Can anything be done about it? Answers from M. Regina Castro, M.D. The dawn phenomenon, also called the dawn effect, is the term used to describe an abnormal early-morning increase in blood sugar (glucose) — usually between 2 a.m. and 8 a.m. — in people with diabetes. Some researchers believe the natural overnight release of the so-called counter-regulatory hormones — including growth hormone, cortisol, glucagon and epinephrine — increases insulin resistance, causing blood sugar to rise. High morning blood sugar may also be caused by insufficient insulin the night before, insufficient anti-diabetic medication dosages or carbohydrate snack consumption at bedtime. If you have persistently elevated blood sugar in the morning, checking your blood sugar once during the night — around 2 a.m. or 3 a.m. — for several nights in a row will help you and your doctor determine if you have the dawn phenomenon or if there's another reason for an elevated morning blood sugar reading. What you can do Your doctor may recommend a number of options to help you prevent or correct high blood sugar levels in the morning: Avoid carbohydrates at bedtime. Adjust your dose of medication or insulin. Switch to a different medication. Change the time when you take your medication or insulin from dinnertime to bedtime. Use an insulin pump to administer extra insulin during early-morning hours. Continue reading >>
Is blood sugar a non-diabetic?
BLOOD SUGARS: THE NONDIABETIC VERSUS THE DIABETIC Since high blood sugar is the hallmark of diabetes, and the cause of every long-term complication of the disease, it makes sense to discuss where blood sugar comes from and how it is used and not used. Our dietary sources of blood sugar are carbohydrates and proteins. One reason the taste of sugar—a simple form of carbohydrate—delights us is that it fosters production of neurotransmitters in the brain that relieve anxiety and can create a sense of well-being or even euphoria. This makes carbohydrate quite addictive to certain people whose brains may have inadequate levels of or sensitivity to these neurotransmitters, the chemical messengers with which the brain communicates with itself and the rest of the body. When blood sugar levels are low, the liver, kidneys, and intestines can, through a process we will discuss shortly, convert proteins into glucose, but very slowly and inefficiently. The body cannot convert glucose back into protein, nor can it convert fat into sugar. Fat cells, however, with the help of insulin, do transform glucose into fat. The taste of protein doesn’t excite us as much as that of carbohydrate— it would be the very unusual child who’d jump up and down in the grocery store and beg his mother for steak or fish instead of cookies. Dietary protein gives us a much slower and smaller blood sugar effect, which, as you will see, we diabetics can use to our advantage in normalizing blood sugars. The Nondiabetic In the fasting nondiabetic, and even in most type 2 diabetics, the pancreas constantly releases a steady, low level of insulin. This baseline, or basal, insulin level prevents the liver, kidneys, and intestines from inappropriately converting bodily proteins (muscle, vital organs) into g Continue reading >>
What causes the dawn phenomenon?
sugar) around the hours of waking, roughly between 4-8 AM. Although the exact underlying causes of the dawn phenomenon are still unclear, it is known that hormone s, including adrenaline, cortisol, glucagon, and growth hormone, play a large part. These hormones follow a circadian rhythm, or a daily cycle, and tend to be found in higher concentrations in the blood in the morning to help prepare us for the day ahead.
Does the dawn phenomenon occur only in people with prediabetes and type 2 diabetes?
Healthy individuals secrete enough insulin and are insulin sensitive enough to counteract a rise in morning blood glucose. However, someone with prediabetes or type 2 diabetes is insulin resistant and/or may not secrete enough insulin, which allows blood glucose to rise. This may be further compounded in the early morning hours because our body is more insulin resistant compared to the rest of the day (1) causing an elevated fasting glucose to remain elevated longer. Progression of prediabetes and type 2 diabetes is likely to result in a worsening of the dawn phenomenon as insulin function and sensitivity continue to diminish.
How can I combat the dawn phenomenon? Will reducing my carb intake help?
If you want to understand if elevated morning blood glucose numbers are a result of the dawn phenomenon or from too many dietary carbohydrates, all you need to do is test at multiple times throughout the day. First and foremost, you should be familiar with what your fasting glucose looks like. Whether it be your most recent lab values from the doctor or checking your glucose with a meter, the best way to know where your fasting glucose falls is to measure it, and to test it on a few different days. Similarly, testing your glucose throughout the day, before and after meals, and before you go to bed can help you understand how your body responds to the food you eat.Once you’ve tested enough that you understand your baseline glucose with your current habits, try incorporating each of the strategies outlined below into your routine. Continue testing your blood glucose and you’ll see what impact each change has on your morning fasting glucose.
Why is HBA1C important?
Because HbA1c is a measure of your blood glucose over the last 3 months. The average value matters more than any individual blood glucose value. Example blood glucose curve of someone controlling their type 2 diabetes through nutritional ketosis who experiences the dawn phenomenon (2) .
Why does fasting glucose stay elevated in the morning?
This may be further compounded in the early morning hours because our body is more insulin resistant compared to the rest of the day (1) causing an elevated fasting glucose to remain elevated longer.

What hormones release glucose into the blood?
The hormones that promote glucose release into the blood include: 1 Adrenaline: Known as the “fight or flight” hormone, adrenaline increases blood flow to the muscles and promotes the release of glucose into the blood. 2 Cortisol: Known as the “stress hormone”, cortisol also plays a role in increasing blood glucose. 3 Glucagon: Signals the liver to release glucose into the blood. 4 Growth Hormone: Important for repair and regeneration and promotes the release of glucose into the blood.
What hormones are involved in the breakdown of glucose?
1) Glycogenolysis, the breakdown and release of stored glucose (a.k.a. glycogen) 2) Gluconeogenesis, the creation of glucose from components of protein (i.e. certain amino acids) or fat (i.e. glycerol) One more hormone that plays an important role is insulin. When blood glucose rises, insulin is released and helps move glucose out ...
What happens to glucose levels after 5:30 a.m.?
After 5:30 a.m., plasma glucose, insulin, and C-peptide concentrations all increased significantly ; rates of glucose production, glucose utilization, and insulin secretion also increased (all P less than 0.05).
Does plasma glucagon change?
Plasma glucagon did not change significantly throughout the period of observation. These results indicate that a dawn-like phenomenon, initiated by an increase in glucose production, occurs in nondiabetic individuals.

What happens in people with diabetes?
Individuals that have diabetes may produce too little insulin. They may also have insulin resistance — when the cells of the body don’t respond to insulin. In this case, blood sugar levels remain high as you wake up in the morning.
Why is the dawn phenomenon important?
Since even small increases in blood sugar levels can impact your health, managing the dawn phenomenon can be an important step in reducing your risk of diabetes complications.
Why does insulin not last in the morning?
This can happen for a couple of reasons. If you inject long-acting insulin early, insulin levels in your bloodstream may not last until the morning. Or, if you use an insulin pump, the levels of insulin it administers in the night may be too low to counteract the dawn phenomenon.
What is dawn phenomenon?
Takeaway. The dawn phenomenon is an increase in blood sugar levels, or hyperglycemia, that happens in the morning. This typically occurs between the hours of 3:00 a.m. and 8:00 a.m. The dawn phenomenon is common in individuals with either type 1 or type 2 diabetes, and it has an estimated prevalence of over 50 percent.
