Diseases of pancreas
MEDOP 230- Endocrinology: Diseases of the pancreas
| Disease | Definition | Note | Symptom |
|---|---|---|---|
| Hyperinsulinism | Condition in which a pancreatic adenoma causes hypersecretion of insulin. | • High insulin levels lead to low blood glucose (hypoglycemia). • If untreated, hypoglycemia can progress to insulin shock and coma. | • Symptoms of hypoglycemia include shakiness, headache, sweating, dizziness, and fainting. |
| Insulin resistance syndrome (IRS) | Condition in which hypersecretion of insulin occurs because cell receptors develop resistance to insulin. | • Receptor resistance- glucose remains in blood instead of entering body cells. • The pancreas senses high glucose level and tries to lower it by secreting more insulin. • Eventually, the pancreas becomes exhausted and the patient develops DM | |
| Diabetes mellitus (DM) hunger). | Condition in which the beta cells of the pancreas are unable to secrete enough insulin. | ||
| hyperglycemia | Low insulin levels | result in elevated blood glucose | |
| Glycosuria | excess glucose in the urine | occurs as the kidneys work to rid the body of the excess glucose. | |
| Polyuria | production of large amounts of urine | develops as the glucose brings water along with it. | |
| Polydipsia | increased thirst | caused by excessive urination | |
| Polyphagia | excess hunger | caused by the inability to metabolize glucose |
