Diabetes is a problem with your body that causes blood sugar (also called blood glucose) levels to rise higher than normal. This is also called hyperglycemia. When you eat, your body breaks food down into sugar and sends it into the blood. Insulin then helps move the sugar from the blood into your cells.
Why is blood sugar high in diabetes?
High blood sugar levels happen when the body either can’t make insulin (type 1 diabetes) or can’t respond to insulin properly (type 2 diabetes). The body needs insulin so glucose in the blood can enter the cells of the body where it can be used for energy.
Is blood sugar related to diabetes?

Drinking water regularly may rehydrate the blood, lower blood sugar levels, and reduce diabetes risk ( 20 , 21 ). Keep in mind that water and other zero-calorie drinks are best. Avoid sugar-sweetened options, as these can raise blood glucose, drive weight gain, and increase diabetes risk ( 22 , 23 ).
How can I quickly lower my blood sugar?
When your blood sugar level gets too high — known as hyperglycemia or high blood glucose — the quickest way to reduce it is to take fast-acting insulin. Exercising is another fast, effective way to lower blood sugar. In some cases, you should go to the hospital instead of handling it at home.

Is 5.7 blood sugar normal?
In general: A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal. A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L ) is considered prediabetes. This result is sometimes called impaired fasting glucose.
Is 170 sugar level normal?
The goal for managing diabetes is to achieve glucose values as close to this as possible, but the recommended range is 80-130 mg/dl. There is no specific value used to define hyperglycemia in all individuals. In general, a glucose level above 160-180 mg/dl is considered hyperglycemia.
