Blood glucose monitoring Most people with type 2 diabetes test at least once per day. The Mayo Clinic generally recommends that diabetics who use insulin (all type 1 diabetics and many type 2 diabetics) test their blood sugar more often (4–8 times per day for type 1 diabetics, 2 or more times per day for type 2 diabetics), both to assess the effectiveness of their prior insulin dose and to help determine their next insulin dose. Blood glucose monitoring reveals individual patterns of blood glucose changes, and helps in the planning of meals, activities, and at what time of day to take medications.
Glucose Glucose Glucose (also called dextrose) is a simple sugar with the molecular formula . Glucose is the most abundant monosaccharide, a subcategory of carbohydrates. Glucose is mainly made by plants and most algae during photosynthesis from water and carbon dioxide, using energy from sunlight. There it is used to make cellulose in cell walls, which is the most abundant carbohydrate. In energy metabolism, glucose is the most important source of energy in all organisms. Glucose for metabolism is partially stored as a polymer, in plants mainly as starch and amylopectin and in animals as glycogen. Glucose circulates in the blood
