Blood sugar Levels Affect on the Body

How blood sugar levels affect the body

Insulin and glucagon don't work straightaway, particularly if the blood sugar is very high or very low.


High blood sugar
Symptoms of high blood sugar include:

Urinating more often than usual. The kidneys respond to high blood sugar by trying to get rid of excess glucose.
Feeling excessively thirsty, especially if also urinating often. As the kidneys try to regulate blood sugar, it can cause dehydration and feelings of intense thirst.
Feeling excessively hungry. This is not caused by high blood sugar, but by the low insulin effect that often goes with high blood sugar.

Excessive hunger and thirst are common symptoms of high blood sugar levels.
