Hypoglycemia can happen for many reasons, though it most commonly occurs in persons on oral medications or on insulin to control diabetes. Low blood sugar must be treated promptly so that it does not progress into diabetic shock or coma. Having regular meals and snacks is important in preventing episodes of hypoglycemia.
Shakiness and Dizziness
You might feel like your hands are trembling so that you have difficulty writing or keeping your hands still. You might feel dizzy, faint and lightheaded or like you are going to pass out. If this is the case, treat yourself with a form of glucose and sit down or lie down.
Hunger and Headache
When your blood sugar is low, the body sends signals that it needs sugar for energy. You might feel very hungry. A sudden craving for sweets or other food is a common sign. You may also feel cold, clammy or sweaty when you have low blood sugar. Having a headache is very common. Check your blood sugar to confirm you are not having a hypoglycemic episode.
Sudden Behavior or Mood Change
You may not feel as alert as you usually do. You might feel irritable or confused suddenly. It is important that this symptom not be written off by others as bad behavior, especially in children who are diabetic.
Other Symptoms
Some persons will report that they feel a tingling sensation around the mouth. Most times, this symptom is accompanied by other symptoms. Your vision might become blurred, or you might have double vision. Some persons may experience seizures as a result of low blood sugar. This is a less common symptom.
