3 reasons why blood sugar increases without a clear cause

It is a common belief that blood sugar levels only increase when you eat too many sweets or white starches. However, the reality is much more complicated. There are hidden, hard-to-see causes that can have a big impact on blood sugar levels.

Several factors can cause high blood sugar even when the patient eats properly, takes medication, and monitors blood sugar levels carefully, according to the health website Healthline (USA).

Lesser-known causes that can cause high blood sugar levels include:

Illness or stress

When you are sick or under prolonged stress, your body releases more cortisol and adrenaline. These are stress hormones that help your body cope with life's risks. However, they also increase blood sugar.

According to the American Diabetes Association, when the body is infected or stressed, the liver releases glucose into the bloodstream. This natural mechanism helps to temporarily increase the body's energy supply. However, for diabetics, due to a decrease in the hormone insulin, their bodies cannot use this glucose effectively. As a result, blood sugar levels increase.

Dehydration can increase blood sugar

Water makes up about 60% of the body. Therefore, dehydration will affect many physiological functions, including blood sugar. When the body lacks water, the amount of sugar in the blood will be more concentrated, causing blood sugar to increase even without eating anything else.

According to the Cleveland Clinic (USA), dehydration reduces plasma volume, causing blood glucose levels to increase. In addition, the kidneys function less effectively when dehydrated, leading to a decrease in the ability to excrete excess sugar through urine. Therefore, if a diabetic feels dry mouth, dizziness or dark urine, drink water immediately.

Side effects of the drug

Certain medications, some of which many people may not think of, can cause high blood sugar. For example, corticosteroids, diuretics, antidepressants, birth control pills, and some antipsychotics can all increase blood glucose levels.

For example, corticosteroids increase insulin resistance and prompt the liver to make more glucose, leading to significant increases in blood sugar. If a diabetic is taking medication and notices an unusual increase in blood sugar, consult your doctor, according to Healthline .
