Diabetes mellitus DM , commonly known as diabetes , is a group of metabolic disorders characterized by a high blood sugar level over a prolonged period of time.
Diabetes means your blood glucose, or blood sugar , levels are too high. With type 2 diabetes, the more common type, your body does not make or use insulin well. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart , eyes , kidneys , nerves , and gums and teeth.
Type 3 Diabetes and Alzheimer’s Disease: What You Need to Know
Diabetes mellitus is a disorder in which the body does not produce enough or respond normally to insulin, causing blood sugar glucose levels to be abnormally high. Diabetes damages blood vessels and increases the risk of heart attack, stroke, chronic kidney disease, and vision loss. People with diabetes need to follow a healthy diet that is low in refined carbohydrates including sugar , saturated fat, and processed foods. They also need to exercise and usually take drugs to lower blood sugar levels. Diabetes mellitus is a disorder in which the amount of sugar in the blood is elevated.
Diabetes mellitus , disorder of carbohydrate metabolism characterized by impaired ability of the body to produce or respond to insulin and thereby maintain proper levels of sugar glucose in the blood. Diabetes is a major cause of morbidity and mortality, though these outcomes are not due to the immediate effects of the disorder. They are instead related to the diseases that develop as a result of chronic diabetes mellitus. These include diseases of large blood vessels macrovascular disease, including coronary heart disease and peripheral arterial disease and small blood vessels microvascular disease, including retinal and renal vascular disease , as well as diseases of the nerves. Insulin is a hormone secreted by beta cells, which are located within clusters of cells in the pancreas called the islets of Langerhans. Patients with diabetes may have dysfunctional beta cells, resulting in decreased insulin secretion, or their muscle and adipose cells may be resistant to the effects of insulin, resulting in a decreased ability of these cells to take up and metabolize glucose.

Type 1 and type 2 diabetes both occur when the body cannot properly store and use glucose, which is essential for energy. Sugar, or glucose, collects in the blood and does not reach the cells that need it, which can lead to serious complications. Type 1 diabetes usually appears first in children and adolescents, but it can occur in older people, too. The immune system attacks the pancreatic beta cells so that they can no longer produce insulin.
Diabetes is a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin secretion, insulin action, or both. The chronic hyperglycemia of diabetes is associated with long-term damage, dysfunction, and failure of differentorgans, especially the eyes, kidneys, nerves, heart, and blood vessels. Several pathogenic processes are involved in the development of diabetes. The basis of the abnormalities in carbohydrate, fat, and protein metabolism in diabetes is deficient action of insulin on target tissues. Impairment of insulin secretion and defects in insulin action frequently coexist in the same patient, and it is often unclear which abnormality, if either alone, is the primary cause of the hyperglycemia. Symptoms of marked hyperglycemia include polyuria, polydipsia, weight loss, sometimes with polyphagia, and blurred vision. Impairment of growth and susceptibility to certain infections may also accompany chronic hyperglycemia.
Diabetes mellitus also called DM or diabetes for short refers to a health condition where your body has difficulty converting sugar to energy. Typically, we think of three kinds of diabetes:. The pancreas has both endocrine and exocrine glands, and they have their respective functions. Insulin is one of the hormones that beta-islet cells in the Islets of Langerhans, which is endocrine pancreas tissue, produce and secrete. When the exocrine pancreas becomes diseased and then causes a secondary insult to the endocrine pancreas that ultimately leads to DM, this is T3cDM. Exocrine pancreatic diseases that may lead to T3cDM include pathology such as:. Over time, untreated diabetes can cause damage to your blood vessels, including vessels in your brain.

Back to Health A to Z. Diabetes is a lifelong condition that causes a person's blood sugar level to become too high. Type 2 diabetes is far more common than type 1.
