A Comprehensive Guide to Diabetes Terminology
Here’s a detailed breakdown of common diabetes-related terms, explained simply and clearly.
A1C (Glycated Hemoglobin)
The A1C test is a blood test that reflects your average blood sugar levels over the past 2-3 months. It measures the percentage of your hemoglobin (a protein in red blood cells that carries oxygen) that is coated with sugar (glucose). Higher A1C levels indicate poorer blood sugar control.
- Normal A1C: Below 5.7%
- Prediabetes A1C: 5.7% - 6.4%
- Diabetes A1C: 6.5% or higher
Example: If your A1C is 7.0%, it means that approximately 7% of your hemoglobin is coated with glucose, indicating that your average blood sugar level has been elevated over the past few months.
Autoantibodies
Autoantibodies are antibodies (proteins produced by the immune system to fight off foreign substances) that mistakenly attack the body's own tissues. In type 1 diabetes, autoantibodies often target the insulin-producing cells (beta cells) in the pancreas, leading to their destruction and a subsequent lack of insulin.
Basal Insulin
Basal insulin is a long-acting type of insulin that provides a steady background level of insulin throughout the day and night. It helps to keep blood sugar levels stable between meals and during sleep. Common examples include insulin glargine (Lantus, Toujeo), insulin detemir (Levemir), and insulin degludec (Tresiba).
Blood Glucose (BG)
Blood glucose (BG), also known as blood sugar, is the concentration of glucose (sugar) in the blood. It is usually measured in milligrams per deciliter (mg/dL) or millimoles per liter (mmol/L). Monitoring your blood glucose levels is crucial for managing diabetes.
- Normal Fasting BG: 70-100 mg/dL
- Normal BG 2 hours after meal: Less than 140 mg/dL
Bolus Insulin
Bolus insulin is a rapid-acting type of insulin taken before meals to cover the carbohydrates you are about to eat. It helps to prevent blood sugar spikes after eating. Examples include insulin lispro (Humalog), insulin aspart (Novolog), and insulin glulisine (Apidra).
Carbohydrates (Carbs)
Carbohydrates (Carbs) are one of the three main macronutrients (along with proteins and fats) found in foods. They are the body's primary source of energy. When you eat carbs, your body breaks them down into glucose, which raises your blood sugar levels. Monitoring carbohydrate intake is essential for diabetes management. Sources include grains, fruits, vegetables, and sugary foods.
Continuous Glucose Monitoring (CGM)
Continuous Glucose Monitoring (CGM) is a device that continuously tracks blood sugar levels throughout the day and night. A small sensor is inserted under the skin to measure glucose levels in the interstitial fluid (fluid surrounding the cells). CGM systems provide real-time glucose readings, trends, and alerts, helping you make informed decisions about your diabetes management. Examples include Dexcom, Freestyle Libre, and Medtronic Guardian. Continuous Glucose Monitor Cgm 101 A Guide For Persons With Diabetes
Diabetes (Diabetes Mellitus)
Diabetes is a chronic metabolic disorder characterized by elevated blood sugar levels. It occurs when the body does not produce enough insulin (type 1 diabetes) or cannot effectively use the insulin it produces (type 2 diabetes). This leads to hyperglycemia (high blood sugar), which can damage various organs and tissues over time. Type 1 Vs Type 2 Diabetes Key Differences In Causes And Treatment
Diabetic Ketoacidosis (DKA)
Diabetic Ketoacidosis (DKA) is a serious complication of diabetes that occurs when the body doesn't have enough insulin to use glucose for energy. As a result, the body starts breaking down fat for fuel, producing ketones (acids) that can build up to dangerous levels in the blood. DKA is more common in people with type 1 diabetes and requires immediate medical attention.
Symptoms of DKA can include:
- Excessive thirst
- Frequent urination
- Nausea and vomiting
- Abdominal pain
- Fruity-scented breath
- Confusion
Gestational Diabetes
Gestational diabetes is a type of diabetes that develops during pregnancy in women who did not have diabetes before. It usually resolves after childbirth but increases the risk of developing type 2 diabetes later in life. It's essential to manage gestational diabetes to protect the health of both the mother and the baby.
Glucagon
Glucagon is a hormone produced by the pancreas that raises blood sugar levels. It is often used to treat severe hypoglycemia (low blood sugar) in people with diabetes. Glucagon works by signaling the liver to release stored glucose into the bloodstream.
Glucometer
A glucometer, also known as a blood glucose meter, is a device used to measure the level of glucose in the blood. A small drop of blood, usually obtained by pricking a fingertip, is placed on a test strip, which is then inserted into the meter. The meter provides a digital reading of the blood glucose level.
Glucose
Glucose is a simple sugar that is the body's main source of energy. It comes from the food we eat, especially carbohydrates. In people with diabetes, the body has difficulty regulating glucose levels, leading to high or low blood sugar.
Hemoglobin
Hemoglobin is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. It is the molecule that is measured in the A1C test.
Hyperglycemia
Hyperglycemia is the medical term for high blood sugar. It occurs when the glucose level in the blood is higher than normal. Chronic hyperglycemia can lead to various health complications, including nerve damage, kidney damage, and cardiovascular disease.
Symptoms of hyperglycemia can include:
- Increased thirst
- Frequent urination
- Blurred vision
- Fatigue
- Headaches
Hypoglycemia
Hypoglycemia is the medical term for low blood sugar. It occurs when the glucose level in the blood is lower than normal. Hypoglycemia can be caused by taking too much insulin, skipping meals, or exercising strenuously.
Symptoms of hypoglycemia can include:
- Shakiness
- Sweating
- Dizziness
- Confusion
- Irritability
- Hunger
- Headache
Insulin
Insulin is a hormone produced by the pancreas that helps glucose enter cells to be used for energy. In people with type 1 diabetes, the pancreas does not produce insulin. In people with type 2 diabetes, the body does not use insulin effectively. Insulin is often prescribed as a medication to help manage blood sugar levels.
Insulin Resistance
Insulin resistance is a condition in which the body's cells do not respond properly to insulin. As a result, the pancreas has to produce more insulin to maintain normal blood sugar levels. Insulin resistance is a key feature of type 2 diabetes.
Ketones
Ketones are chemicals produced when the body breaks down fat for energy. This happens when there isn't enough insulin to use glucose for fuel. High levels of ketones can lead to diabetic ketoacidosis (DKA), a serious complication of diabetes. Ketones can be measured in the blood or urine.
Lipids
Lipids are fats and other fatty substances in the blood. High levels of certain lipids, such as cholesterol and triglycerides, can increase the risk of cardiovascular disease, a common complication of diabetes.
Neuropathy
Neuropathy is nerve damage. Diabetic neuropathy is a common complication of diabetes that can affect nerves throughout the body, causing pain, numbness, tingling, and weakness, particularly in the hands and feet.
Nephropathy
Nephropathy is kidney disease or damage. Diabetic nephropathy is a complication of diabetes that can lead to kidney failure if left untreated. High blood sugar levels can damage the blood vessels in the kidneys, impairing their ability to filter waste products from the blood.
Prediabetes
Prediabetes is a condition in which blood sugar 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, heart disease, and stroke. Lifestyle changes, such as diet and exercise, can help prevent or delay the onset of type 2 diabetes.
Retinopathy
Retinopathy is damage to the retina, the light-sensitive tissue at the back of the eye. Diabetic retinopathy is a complication of diabetes that can lead to vision loss and blindness. High blood sugar levels can damage the blood vessels in the retina.
Type 1 Diabetes
Type 1 Diabetes is an autoimmune disease in which the body's immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body cannot produce insulin, and people with type 1 diabetes require lifelong insulin therapy.
Type 2 Diabetes
Type 2 Diabetes is a metabolic disorder characterized by insulin resistance and progressive loss of insulin secretion from the pancreas. In type 2 diabetes, the body's cells do not respond properly to insulin, and the pancreas eventually cannot produce enough insulin to overcome this resistance. Type 2 diabetes is often associated with obesity, physical inactivity, and a family history of diabetes.
Practical Application and Real-World Scenarios
Understanding these terms is not just about knowing definitions; it's about applying this knowledge in practical situations.
Scenario 1: Doctor's Visit
Imagine you are at a doctor's appointment, and the doctor mentions that your A1C is 7.2%. Now, you know this means your average blood sugar has been high over the past few months, indicating that your diabetes management plan needs adjustment. You can discuss strategies to lower your A1C with your healthcare provider, such as adjusting your bolus insulin doses before meals or increasing your basal insulin.
Scenario 2: Managing Hypoglycemia
You feel shaky and sweaty, and your glucometer reads 65 mg/dL. You recognize these as symptoms of hypoglycemia (low blood sugar). Knowing this, you can quickly take action by consuming a fast-acting carbohydrate source like glucose tablets or juice to raise your blood sugar levels.
Scenario 3: Meal Planning
When planning meals, you now understand the importance of managing your carbohydrate (carb) intake. You can use this knowledge to make informed choices about the foods you eat, aiming for balanced meals that help maintain stable blood glucose (BG) levels. For example, you might pair complex carbohydrates with protein and healthy fats to slow down the absorption of glucose and prevent blood sugar spikes.
