Diabetes Mellitus, Insulin-Dependent (C0011854)

Definition (MEDLINEPLUS)

Diabetes means your blood glucose, or blood sugar, levels are too high. With type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth.

Type 1 diabetes happens most often in children and young adults but can appear at any age. Symptoms may include

  • Being very thirsty
  • Urinating often
  • Feeling very hungry or tired
  • Losing weight without trying
  • Having sores that heal slowly
  • Having dry, itchy skin
  • Losing the feeling in your feet or having tingling in your feet
  • Having blurry eyesight

A blood test can show if you have diabetes. If you do, you will need to take insulin for the rest of your life.

NIH: National Institute of Diabetes and Digestive and Kidney Diseases

Definition (NCI) A chronic condition characterized by minimal or absent production of insulin by the pancreas.(NICHD)
Definition (MSH) A subtype of DIABETES MELLITUS that is characterized by INSULIN deficiency. It is manifested by the sudden onset of severe HYPERGLYCEMIA, rapid progression to DIABETIC KETOACIDOSIS, and DEATH unless treated with insulin. The disease may occur at any age, but is most common in childhood or adolescence.
Definition (CSP) subtype of diabetes mellitus that is characterized by insulin deficiency; it is manifested by the sudden onset of severe hyperglycemia, rapid progression to diabetic ketoacidosis, and death unless treated with insulin; the disease may occur at any age, but is most common in childhood or adolescence.
