Diabetes mellitus (Hyperglycemia):

 
  • The insulin-dependent diabetes mellitus (IDDM) is caused by a failure of the Beta-cells to produce adequate amount of insulin.
  • The non-insulin-dependent diabetes mellitus (NIDDM) appears to involve failure of insulin to facilitate the movement of glucose into cells.
  • In both disorders the blood glucose concentration is elevated above the normal range.
  • Some of the glucose is excreted in the urine, and water follows the glucose, causing excessive urination and dehydration of body tissues. 
  • This causes excessive thirst (polydipsia). 
  • The cells are unable to utilize glucose and other carbohydrates for energy production.
  • They utilize their proteins for it. The person becomes very weak. 
  • Degradation of fats increases, producing ketone bodies (ketosis). 
  • The latter are acidic and poisonous. 
  • Blood cholesterol level rises. Healing power is impaired.
  • A tendency towards non-insulin-dependent diabetes appears to be inherited as an autosomal recessive characteristic.
