A pill taken to lower the level of glucose (sugar) in the blood. Only some people with noninsulin-dependent diabetes take these pills. See also: Oral hypoglycemic agents. One of the sulfonylureas. (Diabeta; Glynase; Micronase; Euglucon) Glycemic index The effect of a food on blood glucose (sugar) levels over a period of time.
Prediabetes, often considered the step before diabetes, is when you have higher than usual blood glucose (blood sugar) levels. Your levels aren’t high enough to be classified as type 2 diabetes.
The normal level for fasting blood sugar in non-diabetic patients is 70 to 99 mg/dL (3.9 and 5.5 mmol/L). Another useful test that has usually done in a laboratory is the measurement of blood HbA1c (hemoglobin A1c) levels. In the blood, there is a molecule called hemoglobin which carries oxygen to the cells. Glucose can attach itself to this ...
People with type 1 diabetes mellitus who must take insulin in full replacement doses are most vulnerable to episodes of hypoglycemia (low blood glucose levels). This can occur if a person takes too much insulin or diabetic medication, does strenuous exercise without eating additional food, misses meals, consumes too much alcohol, or consumes alcohol without food.

Even so, sulfonylureas and insulin are not the only medications available to people with type 2 diabetes these days, said Ng. “Newer blood sugar control medications work by different mechanisms ...
Diabetic ketoacidosis (DKA) is one of the life-threatening severe complications of diabetes that demands immediate attention and intervention. [7] It is considered a medical emergency and can affect both patients with T1D (type 1 diabetes) and T2D (type 2 diabetes), but it is more common in T1D. [8]
Blood-sugar levels naturally fluctuate throughout the day, the body normally maintaining levels between 70 and 110 mg/dL (3.9–6.1 mmol/L). [3] [2] Although 70 mg/dL (3.9 mmol/L) is the lower limit of normal glucose, symptoms of hypoglycemia usually do not occur until blood sugar has fallen to 55 mg/dL (3.0 mmol/L) or lower.
Sustained higher levels of blood sugar cause damage to the blood vessels and to the organs they supply, leading to the complications of diabetes. [48] Chronic hyperglycemia can be measured via the HbA1c test. The definition of acute hyperglycemia varies by study, with mmol/L levels from 8 to 15 (mg/dL levels from 144 to 270). [49]
