The complications of diabetes can dramatically impair quality of life and cause long-lasting disability. Overall, complications are far less common and less severe in people with well-controlled blood sugar levels. [3] [4] [5] Some non-modifiable risk factors such as age at diabetes onset, type of diabetes, gender, and genetics may influence risk.
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]
Patients should closely monitor their sugar levels to ensure that they reduce rather than continue to remain high. High blood sugar levels are not as easy to detect as hypoglycemia and usually happens over a period of days rather than hours or minutes. If left untreated, this can result in diabetic coma and death.
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 ...
The fluctuation of blood sugar (red) and the sugar-lowering hormone insulin (blue) in humans during the course of a day with three meals. One of the effects of a sugar-rich vs a starch-rich meal is highlighted. [1] The blood sugar level, blood sugar concentration, blood glucose level, or glycemia is the measure of glucose concentrated in the blood.
Type 2 diabetes (T2D), formerly known as adult-onset diabetes, is a form of diabetes mellitus that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. [6] Common symptoms include increased thirst , frequent urination , fatigue and unexplained weight loss . [ 3 ]
This resulting hyperglycemia is clinically relevant in diabetic patients as its lasting effects can lead to overall poor glycemic control. In Type 1 diabetics hyperglycemia due to the dawn phenomenon can persist despite adequate insulin compensation overnight, while in Type 2 diabetics the dawn phenomenon has been shown to be resistant to ...
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]
