Did you know you have sugar in your blood? Your body needs glucose, a form of sugar, to have enough energy. After you eat, your blood absorbs glucose. If you eat more sugar than your body needs, your muscles and liver store the extra. When your blood sugar begins to fall, a hormone tells your liver to release glucose. In most people, this raises blood sugar. If it doesn't, you have hypoglycemia, and your blood sugar can be dangerously low. Signs include

• Hunger
• Shakiness
• Dizziness
• Confusion
• Difficulty speaking
• Feeling anxious or weak

Hypoglycemia is usually a side effect of diabetes medicines. Eating or drinking something with carbohydrates can help. If it happens often, your health care provider may need to change your treatment plan.
