Study Notes

Diabetes Mellitus Overview

Diabetes mellitus (DM) is a collection of metabolic disorders, characterized by elevated blood glucose levels.
Abnormal insulin production, impaired insulin utilization, or both contribute to hyperglycemia.
Genetic, autoimmune, viral, and environmental factors (lifestyle, obesity, stress) are involved in the development of DM.
65%-80% of individuals with DM die as a result of heart disease or stroke.
Type 1 DM (10% of cases) is characterized by an autoimmune attack on the pancreatic beta cells, resulting in a complete lack of insulin production.
Type 2 DM (90% of cases) is associated with insulin resistance, where the body's cells do not respond adequately to insulin.
Other types include gestational diabetes, prediabetes, and secondary diabetes. There are a total of 11 categories of diabetes mellitus.

Pathophysiology of Glucagon and Insulin

Glucagon is synthesized and released by the pancreas in response to low blood glucose, promoting glucose production and release, which is important during periods of fasting.
Insulin, the primary metabolic regulator, facilitates glucose transport into cells, lowering blood glucose.
Insulin is continuously released ("basal rate") and delivers "boluses" when food is ingested.
Insulin opposes glucagon, epinephrine, growth hormone, and cortisol to regulate blood glucose concentrations.
Target blood sugar levels are typically between 4-6/7 mmol/L.

Diabetes Diagnostics

Hemoglobin A1C measures glucose levels over a period (90-120 days), providing an indication of long-term blood sugar control.
Fasting plasma glucose measures blood glucose after an overnight fast, often used for diagnosis.
A random plasma glucose test measures blood glucose without regard to timing of meals, and is used if symptoms are present.
The OGTT measures blood glucose after consuming a glucose load of 75g, assessing how the body metabolizes glucose.

Diabetes Clinical Management

Type 1 DM treatment primarily involves exogenous insulin administration via injections or pumps.
Type 2 DM management often starts with lifestyle changes including nutrition, weight loss, exercise, and oral antihyperglycemic agents (OHAs).
OHAs aim to increase insulin production, enhance/improve insulin sensitivity and/or reduce glucose production. Metformin and Gluconorm are examples.
Insulin types are classified based on onset, peak, and duration of action (rapid-acting, short-acting, intermediate-acting, long-acting).

Diabetes Acute Complications

Hypoglycemia, a common acute complication, occurs when blood glucose levels fall below 4 mmol/L. This occurs when there is too much insulin, not enough food, or delays in timing of insulin, or both.
Symptoms include sweating, trembling, palpitations, anxiety, hunger, nausea, tingling, disturbed sleep, weird dreams, lethargy, weakness, dizziness, confusion, headache, drowsiness, vision changes, difficulty speaking, and even unconsciousness. Severity depends on the blood glucose level.
Treatment involves administration of 15-20 grams of fast-acting carbohydrates.
Severe hypoglycemia requires intravenous dextrose and/or glucagon.
Hyperglycemia complications include diabetic ketoacidosis (DKA), and hyperosmolar hyperglycemic syndrome (HHS).

Diabetes Chronic Complications

Chronic complications include vascular damage (retinopathy, nephropathy, neuropathy), cardiovascular disease, infections, and others.
Vascular damage arises from the accumulation of damaging substances in blood vessels, including byproducts of glucose metabolism (e.g., sorbitol).
Risk factors for complications include long-term hyperglycemia and poor self-management.
Foot care is a crucial aspect of diabetes management, as patients with diabetes are highly susceptible to foot problems.

DM: Safety, Cultural, and Foot Care Tips

Important considerations for diabetic care include understanding a patient's needs and lifestyle changes.
Patients should be aware of various risk factors.
Regular foot examinations and proper foot care are crucial to prevent complications.
DM patients should be aware of safety measures and how to recognize and respond to their condition. Important to be careful when mixing medications (alcohol and Metformin).

DM and Alcohol

Alcohol can inhibit glucose production and may alter glucose levels, potentially leading to hypoglycemia/hyperglycemia.
Patients must exercise caution.
Open communication with healthcare providers about alcohol consumption is essential.
Metformin and alcohol may increase the risk of lactic acidosis.
