Why Are My Fasting Blood Sugars So High?

It is relatively more challenging for the body to use insulin and manage blood sugar levels with overweight or obesity. The body fails to actively respond to insulin due to extra weight in the body. It results in increased high fasting blood glucose levels and an increased risk of type 2 diabetes. Insulin insensitivity leads to weight gain, leading to poor insulin sensitivity, creating a loop.

Although the exact mechanisms are unknown, research links fat to insulin resistance and the growth of type 2 diabetes. Therefore, maintaining a healthy weight can help reduce the risk of high fasting blood glucose levels and even reduce the risk of type 2 diabetes.

What Is The Somogyi Effect

A second possible cause of high blood sugar levels in the morning is the Somogyi effect, sometimes also called rebound hyperglycemia. It was named after the doctor who first wrote about it.

If your blood sugar drops too low in the middle of the night while you are sleeping, your body will release hormones in an attempt to rescue you from the dangerously low blood sugar. The hormones do this by prompting your liver to release stored glucose in larger amounts than usual. But this system isnt perfect in a person with diabetes, so the liver releases more sugar than needed which leads to a high blood sugar level in the morning. This is the Somogyi effect.

Understanding Why Are Fasting Glucose Levels High

Fasting glucose levels are your blood sugar levels on an empty stomach. It is usually measured early in the morning when the person wakes up. It is because your body digests the last meal , and the released glucose is either absorbed or stored in the morning. A fasting blood sugar test can diagnose if a person has diabetes or not. For example, it is normal if your fasting blood sugar levels are less than 100mg/dL . However, if the fasting blood sugar level is between 100mg/dL to 125mg/dL, you are in the prediabetic stage. In addition, fasting blood sugar levels above 125mg/dL indicate diabetes.

The readings mentioned above suggest that you should be cautious if your fasting blood sugar levels are above 100mg/dL. High fasting blood sugar levels indicate the stage of diabetes you are at. However, it is possible to manage it. And the results are rewarding. If you are prediabetic, maintaining healthy fasting blood sugar levels can help reverse the condition. Further, it can help prevent the development of diabetes in the future.

A Warning Of Developing Type 2 Diabetes

Impaired fasting glycaemia is sometimes called pre-diabetes. This is when blood glucose levels in the body are raised, but are not high enough to mean that the person has diabetes. IFG means that the body isnt able to use glucose as efficiently as it should. This is because a layer of fat around the cells of the body, prevents insulin doing its job and taking the glucose into the cells of the body where its needed for energy. This situation is reversible by losing weight and hence the fat around the cells disappears. If you dont lose weight however, is it unlikely that you wont eventually develop Type 2 Diabetes.

IFG has no symptoms and can often go undiagnosed for years. Although there are no symptoms, many people diagnosed with IFG are overweight. Nine out of 10 people with IFG have high blood pressure, raised cholesterol levels or a family history of the condition.

IFG can lead to the development of type 2 diabetes. People with IFG are five to 15 times more likely to develop type 2 diabetes than people with normal glucose levels. However, this isnt inevitable. You can take steps to reduce the chances of this happening. People with IFG also have a slightly increased risk of heart disease and stroke.

Signs of high blood sugar levels include:

  • Peeing a lot: The kidneys respond by flushing out the extra glucose in urine. People with high blood sugar need to pee more often and in larger amounts.
  • Drinking a lot: Someone losing so much fluid from peeing that often can get very thirsty.
  • Losing weight even though your appetite has stayed the same: If there isnt enough insulin to help the body use glucose, the body breaks down muscle and stored fat instead in an attempt to provide fuel to hungry cells.
  • Feeling tired: Because the body cant use glucose for energy properly, a person may feel unusually tired.

Why Does Blood Sugar Go Up In The Morning What Is The Dawn Phenomenon

There are a few main reasons why your glucose levels may be higher in the morning. One of these is known as the dawn phenomenon.

The dawn phenomenon occurs early in the morning between 3 am and 8 am while you are still asleep. As morning approaches, the body naturally signals your liver to produce glucose, giving your body the energy it needs for the start of the day. Caused by changes in hormonal levels, the dawn phenomenon happens to all people, with or without diabetes. However, for those without diabetes, insulin levels increase and they do not experience hyperglycemia.

Another reason you may experience higher morning glucose levels is because your injected insulin wears off. If your body has insufficient insulin during the night, your glucose levels may start to rise. To combat this, you may consider trying a new basal insulin, adjusting the timing and amount of your basal dose , or changing your nighttime basal rates .

The last reason you may experience higher morning glucose levels is known as the Somogyi effect. This occurs if your glucose levels fall too low during the night, caused by too much insulin or medication. To respond, your liver produces more glucose to try to maintain your glucose levels, which may result in hyperglycemia. The Somogyi effect is not as common as the other reasons described.

You should also try to drink plenty of sugar-free fluids to prevent dehydration. And if you are feeling unwell, especially if you are vomiting, you should follow any sick day rules you have been given and contact your diabetes healthcare team for advice.

How To Control Blood Sugar With Intermittent Fasting

Why are my Morning Fasting Blood Sugar Levels high?

If youd like to try intermittent fasting for blood sugar control, there are a few things for you to consider, especially if you have diabetes.

Choose an intermittent fasting plan that wont cause you stress. During your fast, your insulin levels decrease. In response, your body releases hormones from your liver, one of which is the stress hormone, cortisol. Cortisol tells the liver to release more glucose. So if youre in a state of stress, or if you have diabetes, your liver is more likely to over-react and release more glucose than you need. As a result, your blood sugar levels will increase.

If youre your blood sugar goes up, and you havent eaten, its likely your liver release glucose into your bloodstream. Exercise is a vital way to utilize sugar in your blood and help your body return to a fat-burning state.

Its uncommon, but fasting can cause you to experience hypoglycemia or low blood sugar. If you have diabetes, this can potentially be dangerous since diabetes medications already put you at risk for low blood sugar. Talk to your doctor about your intent to start a fast, especially if youre on diabetes medications. Its possible for you to fast safely when your doctor manages your diabetes medications appropriately.

Causes Related To Personal Health

Insulin resistance

This condition occurs when the cells in your muscles, fat, and liver are unable to use the glucose in your bloodstream for energy. Your pancreas responds to this increase in glucose by producing more insulin to help your body process it. This excess amount of insulin in the bloodstream can eventually cause your body to lose insulin sensitivity or build resistance to it, leading to higher blood glucose levels.

Bodyweight and body fat

Research connects being overweight and having a higher body fat percentage with high blood glucose levels. In fact, a high body fat percentage might be a clearer indicator of high blood sugar and diabetes than weight or body mass index .

Other health conditions

Certain conditions could make you more likely to have high blood glucose. These include Cushingâs disease, polycystic ovarian syndrome , and gestational diabetes. Blood glucose may also rise as the result of common illnesses like a head cold or the flu.

Hormonal changes

It isnât just stress and sleep that can cause fluctuations in hormones. Illness, physical pain and trauma, menopause or menstruation can as well. In any of these instances, your blood glucose levels may rise due to the changes in your hormone levels.

Medications

Gut issues

A growingbody of research links imbalances in the microbiota living in our guts to an inability to regulate glucose levels in the blood. This is sometimes due to antibiotic use or infection.
