Study Notes

Foundational Concepts of Diabetes

Diabetes is a general term for any metabolic disorder causing excessive thirst and the production of a large volume of urine. Your source material identifies two main types:

Consequences of Sugar Accumulation in DM:
* Hyperglycemia: Sugar appears excessively in the blood.
* Glucosuria: Sugar appears in the urine.
* Ketosis: Accumulation of ketones in the bloodstream, disturbing acid-base balance.
* Diabetic Coma: Can eventually result from severe ketosis.

Insulin Pharmacokinetics and Metabolism

Degradation of insulin primarily occurs in three main areas:
* Liver: About 50% of the insulin reaching the liver via the portal vein is destroyed before it even reaches the general circulation. The liver's degradation capacity is near its maximum.
* Kidney: Insulin is filtered in the renal glomeruli and then reabsorbed and degraded by the renal tubules. If kidney function is diminished, the liver generally cannot compensate for less renal degradation.
* Muscles: These also contribute to insulin degradation.

Pathophysiological Mechanisms & Complications of Diabetes

Diabetes broadly refers to disorders of metabolism causing excessive thirst and large volumes of urine. Specifically, Diabetes Mellitus (the focus here) is a disorder of carbohydrate (CHO) metabolism where sugars aren't properly used for energy due to a lack of pancreatic hormone (insulin). This contrasts with Diabetes Insipidus, a rare metabolic disorder characterized by dilute urine and constant thirst, but not related to blood sugar.

Principles of Insulin Therapy and Management

Insulin is a polypeptide hormone produced in the beta-cells of the Islets of Langerhans within the pancreas. These beta cells make up 60-80% of the islet and are stimulated to secrete insulin by glucose, amino acids, fatty acids, and ketone bodies. Insulin is crucial for controlling the uptake, utilization, and storage of cellular nutrients by activating glucose and ion transport systems.
