Does Blood Sugar Go Up At Night


Its Strange That Blood Sugar In A Diabetic Can Rise Despite Not Having Eaten Anything Since Typically Eating Causes Blood Sugar To Go Up

Sleep Interrupted? The Blood Sugar and Sleep Connection | John Douillard’s LifeSpa

But its no uncommon occurrence that in diabetes, glucose or blood sugar levels can actually rise in the absence of eating.

When we dont take food into our body for energy, our liver will try to help us by releasing glucose into our blood so we have the energy we need to stay alive, says Lucille Hughes, RN, CDE, director of diabetes education at South Nassau Communities Hospital;in Oceanside, NY.

For people with diabetes, the liver may release too much glucose, causing blood sugar to go up.

This is why its so important for diabetics to regularly take blood sugar readings, even if they feel fine.


The liver has hundreds of jobs. One of those jobs is to release glucose into the bloodstream for energy because the body requires energy to function, even when at rest.

Basic bodily functions require energy and glucose provides that energy.

In diabetes, things are out of whack in the body. The liver in the diabetic may sometimes overestimate how much sugar to release into the bloodstream.

Or, to put it another way, the liver over-corrects the problem.

The only way that a diabetic can stay ahead of this curve is to monitor;their glucose levels on a regular basis throughout the day to make sure that the sugar level doesnt sneak its way into getting into a dangerously high range.


Sleep Impacts Brain Function

Glucose is fuel for the brain. It provides the energy needed to carry out its functions. When youâre sleep-deprived, the metabolic activity in your brain decreases significantly.Â;

Overall, studies state that sleep deprivation has damaging effects on brain functionâparticularly functions such as alertness, attention, decision making, and cognitive processes.Â;

How To Prevent Low Blood Sugars In The Future

There is probably no way to completely eliminate low blood sugars at night, but I have learned how to limit them quite a bit. What I do is pretty simple I try to learn from my mistakes. If I have a low during the night, Ill go back and see how my bolus and basal patterns were the day before, what I ate, and what I did.

For example, my last low blood sugar was at 4 am a few nights ago, and when I went back and analyzed the data, this is what I found:

Since it was 4 am and my last snack was at 11 pm, the low couldnt be due to my last bolus. I also hadnt changed my basal amount. However, I had moved my workout to later in the evening. So my conclusion was that to limit future nighttime lows, I should take less basal insulin before I go to bed if I work out later in the evening. Thats a pretty easy fix. I reduced my nightly basal and now Im sleeping through the night again and waking up with perfect sugars.

  • Check your level before bed.;According to Sulay Shah, M.D., a board certified endocrinologist, the only way to know if you are at risk is to monitor your blood glucose levelsas there arent always telltale signs.If you check and you notice that your levels are close to 70 mg/dL at bedtime, then you know you might be at risk, Dr. Shah says. In this case, he recommends eating some complex carbohydrates, like a peanut butter sandwich, an apple with peanut butter or one slice of multigrain toast with some avocado.
  • Dont skip dinner.;If you arent eating dinner, Dr. Shah advises skipping your rapid-acting insulin or medicine, like glipizide or glimepiride, that can decrease your blood sugar levels. The goal here is to match your meal and medication, he says.
  • Monitor your alcohol intake.;If you notice that your blood sugar is dropping after having a few beers or vodka sodas, then Dr. Shah warns that you may need to try to eat complex carbohydrates with the alcohol. Dr. Shah notes that blood sugar tends to drop 3 to 4 hours after drinking alcohol. When you regularly drink alcohol, you are decreasing the amount of stored glucose in the liver which helps to maintain a blood sugar in normal range, he explains.

    How Does Lack Of Sleep Raise Your Risk

    Itâs hard to know for certain. Many studies have suggested that short sleepers have irregular eating habits, snack more, and are more likely to eat unhealthy foods.

    Other research has found that shortchanging sleep can directly affect how the body makes other hormones, which in turn affect blood sugar. For example, when you stay up late, your body makes more of the hormone cortisol, which affects how insulin works.

    Also, growing evidence shows that disrupting your bodyâs biological clock by being awake at night can make your cells more resistant to insulin. In one study, researchers altered the circadian rhythms of 16 healthy volunteers by allowing only 5 hours of sleep each night for 5 nights, much like a sleep-deprived workweek. When those volunteers ate food at night — a time when the body isnât biologically prepared for a spike in blood sugar — their bodies didnât use insulin normally.

    How Can You Tell The Difference

    The Somogyi effect can occur any time you or your child has extra insulin in the body. To sort out whether an early morning high blood sugar level is caused by the dawn phenomenon or Somogyi effect, check blood sugar levels at bedtime, around 2 a.m. to 3 a.m., and at your normal wake-up time for several nights. A continuous glucose monitor could also be used throughout the night.

    • If the blood sugar level is low at 2 a.m. to 3 a.m., suspect the Somogyi effect.
    • If the blood sugar level is normal or high at 2 a.m. to 3 a.m., it’s likely the dawn phenomenon.

    Real Reason Why Blood Sugar is High In The Morning? Quiz below!

    People with diabetes can have low blood sugar levels because of the medicines they have to take to manage their diabetes. They may need a hormone called or diabetes pills to help their bodies use the sugar in their blood.


    These medicines help take the sugar out of the blood and get it into the bodys cells, which makes the blood sugar level go down. But sometimes its a tricky balancing act and blood sugar levels can get too low.

    People with diabetes need to keep their blood sugars from getting too highor too low. Keeping blood sugar levels in a healthy range means balancing when and what they eat, and when they exercise with when they take medicines.

    Whether you were recently diagnosed with type 2 diabetes or have been living with the condition for several years, you know how fickle blood sugar levels can be, and how important it is that they stay controlled.

    Proper blood sugar control is key for warding off potential;diabetes;complications, such as kidney disease, nerve damage, vision problems, stroke, and heart disease, according to the National Institutes of Health . Plus, keeping your levels in check on a daily basis can help you stay energized, focused, and in a good mood, explains Lisa McDermott, RD, CDCES,;a diabetes specialist with the Pittsburgh-based Allegheny Health Network.


    According to the American Diabetes Association , proper medication, effective meal planning, regular exercise, and regular blood sugar checks can all help you keep your levels within a healthy range. The ADA recommends blood glucose stay within 80 to 130 milligrams per deciliter before meals and below 180 mg/dL two hours after the start of a meal. Furthermore, the organization recommends getting an;A1C test, which measures your average blood glucose over the past two to three months, at least twice per year if your levels are stable and you are meeting treatment goals.

    What Happens To Blood Sugar While You Sleep

    Itâs tied to whether the hormone insulin, which removes glucose from the blood, is working the way itâs supposed to. Blood sugar levels surge while youâre sleeping, usually around 4 to 8 a.m. for someone with a normal sleep schedule. In a healthy person, insulin can handle the surge by telling muscle, fat, and liver cells to absorb the glucose from the blood, which keeps your levels stable.

    For people who have diabetes or who are likely to get it, insulin canât do that job very well, so blood sugar levels will rise higher.

    High Blood Sugar Levels In The Morning

    A person usually has slightly higher blood sugar or glucose levels in the morning. But, in some people with diabetes, these levels are significantly high.

    that get worse over time, due to these blood sugar spikes.


    According to the National Institute of Diabetes and Digestive and Kidney Diseases, healthy blood sugar levels are:

    • from 80130 milligrams per deciliter just before eating
    • below 180 mg/dl 2 hours after eating

    In addition, they note that:

    • A low blood sugar level is under 70 mg/dl.
    • A high blood sugar level is over 180 mg/dl.

    There are two main causes of high blood sugar in the morning: the dawn phenomenon and the Somogyi effect.

    This article explores these causes, including what they can mean for a persons health and when to see a doctor.

    The dawn phenomenon relates to natural body changes that occur during the sleep cycle.


    In the morning, everyone experiences a slight rise in blood glucose levels. A person without diabetes will not experience effects, as their body can adjust. For a person with diabetes, however, this rise can be significant, and it may need treatment.

    At the same time, the body is producing glucagon, another hormone, which can lead to a further rise in blood sugar.

    This happens just as nighttime levels of insulin are starting to taper off.

    Blood Sugar And Sleep Problems

    Sleep can affect your blood sugar levels, and your blood glucose control can also affect your sleep. ;Its a vicious cycle.

    As the amount of sleep decreases, blood sugar increases, escalating the issue. Lack of sleep has been shown to increase blood sugar levels and the risk of diabetic issues. Higher blood sugar means less long-lasting fat metabolism in the night and even less sleep.


    Researchers at Boston University School of Medicine found that people who slept less than 6 hours a night had more blood sugar complications compared to those who received 8 hours of sleep.;

    What Is A Dangerous Blood Sugar Level

    WHY is my blood sugar UP AND DOWN? Role of diabetic medicines & diet in type 2 diabetes treatment.

    A normal blood sugar level is between 70 and 130 after you have been fasting for a few hours. Blood sugar levels can be dangerous if they are too high or too low.

    Low blood sugars can be caused by not eating enough, or by trying to lower your sugar too quickly. A blood sugar under 60 is considered dangerous. It can lead to confusion or loss of consciousness, which can be deadly. It is important to have a snack with you at all times in case this happens to you. If it does happen, think about what you did or didnt do that lead to the low number. If it happens often, start writing things down to help you track what the cause is so that you can avoid it.

    High blood sugars over 300 are pretty concerning.; A lot depends on what your sugar typically runs. If you are normally in the 200s, then a sugar of 320 wouldnt affect you the way that it would for someone whose typically runs 150.

    If your blood sugar gets too high, then you may have Ketoacidosis. What happens is that the body does not have enough insulin to use the glucose cells, so it starts to break down fat and muscle for fuel. This causes ketones to enter the bloodstream and causes a pretty bad chemical imbalance. Ketones can also be found in your urine, which is an easy way to test. Signs of Diabetic Ketoacidosis are:

    • Fruity smelling breath
    • Loss of vision
    • An abnormal increase in blood sugar

    You should also seek medical attention for this as well to rehydrate your body before any complications happen.

    How Is It Determined If The Dawn Phenomenon Or Somogyi Effect Is Causing The High Blood Sugar Levels

    Your doctor will likely ask you to check your blood sugar levels between 2 a.m. and 3 a.m. for several nights in a row. If your blood sugar is consistently low during this time, the Somogyi effect is suspected. If the blood sugar is normal during this time period, the dawn phenomenon is more likely to be the cause.

    Some additional clues that the Somogyi effect may be the cause include nightmares, restless sleep and overnight sweating as these are all signs of low blood sugar levels.
