Diabetes Mellitus
MEDOP 230- Endocrinology: Diabetes Mellitus
Type | Definition | Note | Treatment |
---|---|---|---|
Type 1 *insulin-dependent diabetes mellitus (IDDM)* | the pancreas secretes no insulin and the patient must receive insulin injections. | • Sometimes known as juvenile-onset diabetes mellitus because it develops during childhood, adolescence, or young adulthood. • Is an autoimmune disease in which the body makes antibodies against the islets of Langerhans. | requires drug therapy with insulin. |
Type 1.5 *latent autoimmune diabetes in adults (LADA)* | the pancreas still secretes some insulin—just not enough. | • Similar to type 1 diabetes in that it is an autoimmune disorder in which the body makes antibodies against the pancreas. | treated similarly to type 2, although insulin will more likely be required. |
Type 2 *non-insulin-dependent diabetes mellitus (NIDDM)/adult- onset diabetes mellitus (ADDM)* | insulin secretion is decreased because the patient is obese and has developed insulin resistance. | • Is not the result of an autoimmune disorder. | typically managed with oral antidiabetic drugs and occasionally insulin. |
Gestational diabetes mellitus (GDM) | Occurs in some women during pregnancy, when increased levels of estradiol and progesterone block the action of insulin | resolves upon delivery of the baby. | |
Oral antidiabetic drugs stimulate the pancreas to produce more insulin, so they do not work for patients with type 1 DM. | |||
Complication: Diabetic ketoacidosis (DKA) | Condition in which a high level of acidic substances called ketones accumulates in the blood because the body metabolizes fat rather than glucose | this lowers the blood pH and can lead to diabetic coma. | |
Complication: Diabetic neuropathy | Decreased or abnormal sensation in the extremities due to damage to the myelin sheaths around nerves. | ||
Complication: Diabetic nephropathy | Condition in which high levels of glucose and ketones cause degenerative changes in the nephrons of the kidneys | can lead to kidney failure. | |
Complication: Diabetic retinopathy | Degenerative changes in the retina due to the local effect of excess glucose and ketones | also involves formation of fragile blood vessels that rupture easily. | |
Complication: Atherosclerosis | Formation of fatty deposits and plaques in the arteries | process is accelerated in patients with DM because of abnormalities in fat metabolism. | |
Complication: Impotence | Difficulty achieving an erection | may occur as a result of nerve damage and atherosclerosis. | |
Complication: Foot injury | Patients with DM are at increased risk due to poor eyesight and decreased sensation. | • Wound healing is slow because of poor blood flow and high blood glucose. • Small injuries may progress to ulcers or gangrene. |
