High blood sugar may be related to the liver.
The liver is a storage organ that synthesizes and releases glycogen, which is closely related to the stabilization of blood glucose. The liver can absorb and utilize glucose, convert glucose into hepatic glycogen for storage, which in turn lowers blood glucose, or the liver can break down hepatic glycogen, which provides energy for the body.
In severe liver disease, the synthesis of hepatic glycogen is blocked and the storage of hepatic glycogen is reduced, resulting in increased blood glucose concentration half an hour to one hour after eating but normal fasting blood glucose and normal or lower than normal blood glucose two to three hours after meals, so high blood glucose may be related to the liver.
It is recommended that you visit a hospital and ask your doctor to make a judgment if you have abnormal liver function or abnormal blood glucose values.
