HDL cholesterol: High-density-lipoprotein (HDL), a fat found in the blood, takes extra cholesterol from the blood to the liver for removal. Also called “good” cholesterol

 

Hemodialysis: The use of a machine to clean wastes from the blood after the kidneys have failed. The blood travels through tubes to a dialyzer, a machine that removes wastes and extra fluid. The cleaned blood then goes back into the body

 

Hemoglobin A1C test: See A1C

 

Heredity: The passing of a trait from parent to child

 

High blood glucose: See hyperglycemia

 

High blood pressure: See hypertension

 

Honeymoon phase: Temporary remission of hyperglycemia that occurs in some people newly diagnosed with type 1 diabetes, when some insulin secretion resumes for a short time, usually a few months, before stopping again

 

Hormone: A chemical produced in one part of the body and released into the blood to trigger or regulate particular functions of the body. For example, insulin is a hormone made in the pancreas that tells other cells when to use glucose for energy. Synthetic hormones, made for use as medicines, can be the same or different from those made in the body

 

Human leukocyte antigens (HLA): Proteins located on the surface of the cell that help the immune system identify the cell either as one belonging to the body or as one from outside the body. Some patterns of these proteins may mean increased risk of developing type 1 diabetes

 

Hyperglycemia: Excessive blood glucose. Fasting hyperglycemia is blood glucose above a desirable level after a person has fasted for at least 8 hours. Postprandial hyperglycemia is blood glucose above a desirable level 1 to 2 hours after a person has eaten

 

Hyperinsulinemia: A condition in which the level of insulin in the blood is higher than normal. Caused by overproduction of insulin by the body. Related to insulin resistance

 

Hyperlipidemia: Higher than normal fat and cholesterol levels in the blood

 

Hyperosmolar hyperglycemic nonketotic syndrome (HHNS): An emergency condition in which one’s blood glucose level is very high and ketones are not present in the blood or urine. If HHNS is not treated, it can lead to coma or death

 

Hypertension: A condition present when blood flows through the blood vessels with a force greater than normal. Also called high blood pressure. Hypertension can strain the heart, damage blood vessels, and increase the risk of heart attack, stroke, kidney problems, and death

 

Hypoglycemia: A condition that occurs when one’s blood glucose is lower than normal, usually less than 70 mg/dL. Signs include hunger, nervousness, shakiness, perspiration, dizziness or light-headedness, sleepiness, and confusion. If left untreated, hypoglycemia may lead to unconsciousness. Hypoglycemia is treated by consuming a carbohydrate-rich food such as a glucose tablet or juice. It may also be treated with an injection of glucagon if the person is unconscious or unable to swallow. Also called an insulin reaction

 

Hypoglycemia unawareness: A state in which a person does not feel or recognize the symptoms of hypoglycemia. People who have frequent episodes of hypoglycemia may no longer experience the warning signs of it

 

Hypotension: Low blood pressure or a sudden drop in blood pressure. Hypotension may occur when a person rises quickly from a sitting or reclining position, causing dizziness or fainting
