Hypoglycemic drugs used by patients with hypoglycemia include acarbose, voglibose and miglitol. Eating starchy foods such as biscuits and steamed bread will reduce the sugar-raising effect, because drugs will inhibit the decomposition of carbohydrates into glucose. Such patients should directly supplement foods that can be converted into glucose as soon as possible, such as candy, sugar tablets or fruits with high sugar content, which is both quick and effective.
