Are high blood sugar and diabetes the same thing?

High blood sugar and diabetes are not the same thing.

High blood sugar refers to the concentration of glucose in the blood exceeding the normal range, but high blood sugar does not necessarily mean diabetes. There are many reasons for high blood sugar. For example, under stress conditions, such as strenuous exercise, emotional excitement, infection, surgery, etc., the body will secrete some hormones that cause temporary increases in blood sugar; ingesting too much high-sugar food at one time may also cause temporary high blood sugar. In addition, the use of certain drugs may also affect blood sugar levels. Diabetes is a chronic disease characterized by a prolonged increase in blood sugar levels. Diabetes is related to a variety of factors, including genetic factors, environmental factors, lifestyle, etc. Diabetes patients due to insufficient insulin secretion or function defects, resulting in blood sugar can not be effectively used and stored, resulting in sustained blood sugar rise. Diabetes can cause damage to many organs and systems of the body, such as cardiovascular system, kidneys, eyes, nervous system, etc., increasing the risk of various complications, such as coronary heart disease, kidney failure, retinopathy, neuropathy, etc.
