Hyperosmolar hyperglycemic state (HHS), also known as hyperosmolar non-ketotic state (HONK), is a complication of diabetes mellitus in which high blood sugar results in high osmolarity without significant ketoacidosis. [4] [5] Symptoms include signs of dehydration, weakness, leg cramps, vision problems, and an altered level of consciousness. [2]
Acute complications are complications that develop rapidly and can be exemplified as diabetic ketoacidosis (DKA), hyperglycemic hyperosmolar state (HHS), lactic acidosis (LA), and hypoglycemia. [1] Chronic complications develop over time and are generally classified in two categories: microvascular and macrovascular .
Hyperosmolar syndrome or diabetic hyperosmolar syndrome is a medical emergency caused by a very high blood glucose level. The prefix " hyper- " means high, and " osmolarity " is a measure of the concentration of active particles in a solution , so the name of the syndrome simply refers to the high concentration of glucose in the blood .
Chronic hyperglycemia (high blood sugar) injures the heart in patients without a history of heart disease or diabetes and is strongly associated with heart attacks and death in subjects with no coronary heart disease or history of heart failure. [22] Also, a life-threatening consequence of hyperglycemia can be nonketotic hyperosmolar syndrome. [16]
Hyperosmolar nonketotic coma (usually type 2) in which an extremely high blood sugar level and dehydration alone are sufficient to cause unconsciousness. In most medical contexts, the term diabetic coma refers to the diagnostical dilemma posed when a physician is confronted with an unconscious patient about whom nothing is known except that ...
Each year, about 4% of type 1 diabetics in the United Kingdom develop DKA, versus 25% of type 1 diabetics in Malaysia. [1] [5] DKA was first described in 1886 and continued to be a universally fatal condition until introduction of insulin therapy in the 1920s. [7] With adequate and timely treatment today, the risk of death is between <1% and 5% ...
Insulin resistance syndrome A syndrome (set of signs and symptoms) resulting from insulin resistance. It is also called metabolic syndrome. Insulin shock A severe condition that occurs when the level of blood glucose (sugar) drops too far and quickly. The signs are shaking, sweating, dizziness, double vision, convulsions, and collapse.
The World Health Organization definition of diabetes (both type 1 and type 2) is for a single raised glucose reading with symptoms, otherwise raised values on two occasions, of either: [65] fasting plasma glucose ≥ 7.0 mmol/L (126 mg/dL) or. glucose tolerance test with two hours after the oral dose a plasma glucose ≥ 11.1 mmol/L (200 mg/dL)
