DM is a group of diseases characterized by hyperglycemia ( elevated blood glucose ) resulting from defects in insulin secretion, insulin action, or both.
Diabetes mellitus is not infectious but it is inheritable especially the type 2 diabetes mellitus.
Diabetes is a chronic disease which requires early diagnosis and regular and prolonged treatment, or complications are likely to occur and to threaten health and life. There are three main acute complications: hypoglycemia, ketoacidosis, and hyperosmolar hyperglycemic syndrome.
Diabetic ketoacidosis ( DKA ) is a state of insulin deficiency. When the glucose is unable to enter cells and accumulates within bloodstream, it triggers high blood sugar.
When patients sense hunger, dizziness, tremor, cold sweating, and lack of strength, their plasma glucose level is often lower than 70 mg/dl - the typical symptoms of hypoglycemia.
Due to recent changes in lifestyles, the average life has prolonged while the population of chronic diseases has risen annually. This is most obvious in the rapid increase of diabetes patients.
