The general goal of the diabetes treatment is to maintain normal glycemic levels.
Type I diabetes is treated with parenteral administration of insulin. Insulin must be administered intravenously or intramuscularly because as a protein it would be digested if ingested orally. In type II diabetes treatment is done with oral drugs that regulate the glucose metabolism or in more severe cases with parenteral administration of insulin. The moderation of carbohydrate ingestion is an important aid to diabetes treatment.
The diabetes treatment with the use of hypoglycemic agents, like insulin or oral medicines, must be carefully and medically supervised since if wrongly used these drugs may abruptly decrease the glucose blood level, cause hypoglycemia and even death.
Many other forms of diabetes treatment are under research worldwide.
