Find definitions of common diabetes and other medical terms
Like any medical condition, diabetes comes with its own language that you need to learn and understand. This can help you have more productive conversations with your healthcare team. Below are some of the common terms you will come across in this site.1
A low, steady flow of longer-acting insulin.
A cut or surface. Usually used to describe the features of a pen needle tip.
Blood glucose meter
A small, portable machine used to check blood glucose levels. After a finger is pricked with a lancet for a small drop of blood, the drop is placed on a test strip in the meter. The meter then displays the blood glucose level.
The main sugar found in the body and the body's main source of energy. Also called blood glucose.
Body mass index (BMI)
A measure used to assess a person's body weight relative to their height. BMI is used to determine if a person is underweight, normal weight, overweight or obese.
An extra amount of fast-acting insulin taken to cover a planned rise in blood glucose, such as a meal or a snack.
A term used to describe a needle that has thinner walls and a wider internal diameter than a standard thin-wall needle.
A measure of how thin a needle is. The larger the gauge number, the thinner the needle.
A type of diabetes that develops when a woman is pregnant and then usually goes away after delivery. Gestational diabetes increases the risk that the mother will develop diabetes later in life.
A type of carbohydrate-rich food made from hard, dry seeds. The two main types are cereals (e.g., wheat, rye) and legumes (e.g., beans, soybeans).
A type of injectable medication that causes the pancreas to release more insulin and the liver to release less sugar into the bloodstream. Also called glucagon-like peptide 1 receptor antagonist.
A medical term usually used to refer to blood sugar levels (e.g., glycemic control, hypoglycemia).
A chemical messenger made in one part of the body that triggers an action in another part of the body.
When blood sugar is too high. Healthcare teams may be interested in fasting hyperglycemia (i.e., the blood sugar after eight hours without eating) or postprandial hyperglycemia (i.e., the blood sugar one to two hours after eating).
