Symptoms of type 2 diabetes excessive weight gain(those over 40)-excessive thirst-excessive urination-excessive weakness-poor circulation-slow healing-vision problems
Sulfonylureas are? oral hypoglycemic drugs that work by increasing insulin production from the pancreas and improving peripheral insulin activity
Side effects of sulfonylureas? GI distress-weakness-fatigue-lethargy-vertigo-headache-hypoglycemia
How do alpha-glucosidase inhibitors work? By delaying digestion of complex carbohydrates and subsequent absorption of glucose. *Take with 1st bite of meals
