Study Notes
Glucose Regulation
- Insulin is the hormone responsible for allowing glucose to enter cells.
- Normal glucose levels in the body range from 70-140 mg/dL.
- The liver releases glucose into the bloodstream.
- Ketone bodies are produced when the body breaks down fat for energy instead of glucose.
Diabetes
- Type 1 Diabetes is caused by a lack of insulin production.
- Type 2 Diabetes is characterized by insulin resistance and impaired insulin secretion.
- Insulin is the main hormone released in the 'fed state' and promotes glucose uptake.
- Glucagon, released from pancreatic alpha cells, raises blood glucose levels by breaking down glycogen and increasing gluconeogenesis.
Pancreatic Functions
- Beta cells produce insulin, the main source of energy in the body.
- Glucagon, released from pancreatic alpha cells, stimulates glucose release from the liver.
Diabetes and Other Systems
- Diabetes is linked to poor dental care, as high blood sugar levels can lead to oral health issues.
- Incretin, a hormone stimulated by food, stimulates insulin response from beta cells and inhibits gastric emptying.
- Gastrin, another hormone, has minimal effects on gastric emptying and does not inhibit glucagon secretion from alpha cells.
Diabetes Diagnosis and Complications
- Hemoglobin A1C (HbA1C) is the main diagnostic test for diabetes, measuring the 3-month average of serum glucose.
- Diabetes can lead to acute complications, including Diabetic Ketoacidosis (DKA), which is caused by a lack of insulin and characterized by high blood sugar, ketone buildup, and acidosis.
- Clinical presentations of DKA include nausea, vomiting, abdominal pain, and rapid breathing.
Microvascular Complications
- Diabetic retinopathy is a microvascular complication directly related to diabetes and blood pressure control.
- The most common type of neuropathy associated with diabetes is peripheral neuropathy.
- The initial phase of nephropathy associated with diabetes is characterized by microalbuminuria.
- The recommended treatment for retinopathy associated with diabetes is laser photocoagulation.
Prevention and Treatment
- Intensive therapy has been shown to reduce the risk of retinopathy and nephropathy in diabetes patients.
- In the DCCT study, intensive therapy resulted in an approximate 1.9% difference in A1C levels compared to conventional therapy.
- The goal A1C level recommended by the ADA is <7.0%.
- The normal range for A1C levels is 4.0-5.6%.
- The primary prevention strategy for retinopathy and nephropathy in diabetes patients is tight blood sugar control.
- Other causes of neuropathy associated with diabetes include vitamin deficiencies, thyroid dysfunction, and concurrent medical conditions.
