Core Concepts: Understanding Blood Sugar and Insulin

To fully grasp the diabetes lexicon, it's essential to understand the fundamental relationship between blood sugar (glucose) and insulin. After we eat, our bodies break down carbohydrates into glucose, which enters the bloodstream. Insulin, produced by the pancreas, acts like a key, unlocking cells to allow glucose to enter and be used for energy. In people with diabetes, either the pancreas doesn't produce enough insulin (type 1 diabetes) or the body's cells become resistant to insulin's effects (type 2 diabetes), leading to elevated blood glucose levels.

1. Glucose (Blood Sugar)

Glucose is a simple sugar that is the body's primary source of energy. It comes from the food we eat, especially carbohydrates. After digestion, glucose is absorbed into the bloodstream, raising blood sugar levels.

Normal Range: A normal fasting blood glucose level is generally between 70 and 99 mg/dL.
Hyperglycemia: High blood sugar; occurs when there is too much glucose in the blood. Symptoms can include increased thirst, frequent urination, and blurred vision.
Hypoglycemia: Low blood sugar; occurs when there is too little glucose in the blood. Symptoms can include shakiness, sweating, confusion, and dizziness.

2. Insulin

Insulin is a hormone produced by the beta cells of the pancreas. It plays a critical role in regulating blood glucose levels by allowing glucose to enter cells for energy or storage.

Insulin Resistance: A condition in which cells do not respond effectively to insulin, requiring the pancreas to produce more insulin to maintain normal blood glucose levels.
Basal Insulin: Long-acting insulin that provides a steady background level of insulin throughout the day.
Bolus Insulin: Rapid-acting insulin taken before meals to cover the glucose from food.

Example: The Body's Glucose Regulation Process

Imagine eating a slice of pizza. The carbohydrates in the pizza are broken down into glucose, which enters your bloodstream. In someone without diabetes, the pancreas would release insulin to allow that glucose to enter your cells, keeping your blood sugar levels stable. However, in someone with diabetes, this process is impaired, leading to high blood sugar levels if not managed appropriately.

Decoding Diabetes Terminology: A Comprehensive A-Z Guide

This section provides a detailed glossary of common diabetes terms, covering various aspects of the condition from diagnosis to management.

A1C (Glycated Hemoglobin): A blood test that reflects average blood glucose levels over the past 2-3 months. Target A1C levels vary depending on individual circumstances but are generally below 7%.
Autoimmune Disease: A condition in which the body's immune system attacks its own cells. Type 1 diabetes is an autoimmune disease where the immune system destroys the insulin-producing beta cells in the pancreas.

Basal Rate: The continuous, low-dose delivery of insulin by an insulin pump to cover the body's basic insulin needs between meals and during sleep.
Blood Glucose Meter (Glucometer): A device used to measure the level of glucose in the blood.
BMI (Body Mass Index): A measure of body fat based on height and weight, used to assess whether a person is underweight, normal weight, overweight, or obese.

Carbohydrates (Carbs): One of the three macronutrients in food (along with protein and fat). Carbs are the primary source of glucose for the body.
Continuous Glucose Monitor (CGM): A device that continuously tracks glucose levels in real-time through a sensor inserted under the skin. It provides trends and alerts about high and low glucose levels.
Complications: Long-term health problems that can arise from poorly controlled diabetes, such as neuropathy, nephropathy, retinopathy, and cardiovascular disease.

Diabetes Distress: The emotional burden, stress, and feelings of frustration or being overwhelmed that can accompany living with diabetes.
DKA (Diabetic Ketoacidosis): A serious complication of diabetes that occurs when the body produces high levels of blood acids called ketones. It's often caused by insufficient insulin and can be life-threatening.
Dawn Phenomenon: An increase in blood glucose levels in the early morning hours, typically between 3 AM and 8 AM.

Endocrinologist: A doctor who specializes in hormone-related conditions, including diabetes.

Fasting Blood Glucose: Blood glucose level measured after an overnight fast (usually at least 8 hours).
Foot Care: Essential for people with diabetes to prevent foot ulcers and infections due to neuropathy and poor circulation.

Gestational Diabetes: Diabetes that develops during pregnancy. It usually disappears after delivery but increases the risk of developing type 2 diabetes later in life.
Glycemic Index (GI): A measure of how quickly a food raises blood glucose levels.
Glycemic Load (GL): A measure that considers both the GI of a food and the amount of carbohydrate it contains, providing a more accurate picture of its effect on blood glucose.

Honeymoon Phase: A temporary period in type 1 diabetes where the pancreas still produces some insulin, reducing the need for injected insulin.
Hyperglycemia: High blood sugar; occurs when there is too much glucose in the blood. Symptoms can include increased thirst, frequent urination, and blurred vision.
Hypoglycemia: Low blood sugar; occurs when there is too little glucose in the blood. Symptoms can include shakiness, sweating, confusion, and dizziness.

Insulin Pump: A small, computerized device that delivers insulin continuously throughout the day through a catheter inserted under the skin.
Islets of Langerhans: Clusters of cells in the pancreas that produce insulin, glucagon, and other hormones.

Ketones: Chemicals produced when the body breaks down fat for energy because it doesn't have enough insulin to use glucose.

LADA (Latent Autoimmune Diabetes in Adults): A form of type 1 diabetes that develops slowly in adults, often misdiagnosed as type 2 diabetes.
Lipohypertrophy: Lumpy, raised areas under the skin caused by repeated insulin injections in the same spot.

Macrovascular Disease: Disease of the large blood vessels, leading to conditions like heart attack, stroke, and peripheral artery disease.
Microvascular Disease: Disease of the small blood vessels, leading to complications like retinopathy, nephropathy, and neuropathy.

Nephropathy: Kidney disease caused by damage to the small blood vessels in the kidneys.
Neuropathy: Nerve damage caused by high blood glucose levels, leading to numbness, tingling, pain, and other symptoms.

Oral Hypoglycemic Agents: Medications taken by mouth to lower blood glucose levels in people with type 2 diabetes.

Postprandial Blood Glucose: Blood glucose level measured 1-2 hours after eating.
Prediabetes: A condition in which blood glucose levels are higher than normal but not high enough to be diagnosed as diabetes. People with prediabetes are at increased risk of developing type 2 diabetes.

Retinopathy: Eye disease caused by damage to the small blood vessels in the retina.

Somogyi Effect: A rebound high blood glucose level in the morning caused by an overnight low blood glucose level.
Sulfonylureas: A class of oral hypoglycemic agents that stimulate the pancreas to release more insulin.

Type 1 Diabetes: An autoimmune disease in which the body's immune system destroys the insulin-producing beta cells in the pancreas, requiring lifelong insulin therapy.
Type 2 Diabetes: A condition in which the body's cells become resistant to insulin, and the pancreas may not produce enough insulin to overcome this resistance. It is often associated with obesity and lifestyle factors.

Urine Ketones: Ketones present in the urine, indicating that the body is breaking down fat for energy due to insufficient insulin.
