The pancreatic gland is an organ that secretes insulin in the body. When pancreatitis occurs, the function of the pancreas decreases and the secretion of insulin decreases, thus causing secondary diabetes. For acute pancreatitis after hospitalization to give active treatment, pancreatitis disease control and stabilization, blood sugar will also decline. Because the function of the pancreas is restored at this time, the natural function of the pancreatic secretion will be restored and the body will regulate blood sugar. In the case of permanent secondary diabetes, it is necessary to give subcutaneous insulin injections to lower blood sugar, and the specific method of insulin use requires consultation with an endocrinologist.
