What Is Hypoglycemia?

Hypoglycemia means your blood sugar level is lower than normal. Blood sugar, or glucose, gives your body energy. When levels drop too low, your body cannot work well. Hypoglycemia can happen to anyone, but it is more common in people with diabetes. According to the Centers for Disease Control and Prevention (CDC), knowing about hypoglycemia helps you stay safe. For this reason, it is important to learn the signs and causes of hypoglycemia.

Common Causes of Hypoglycemia

There are several causes of hypoglycemia. Sometimes, it happens because of diabetes treatment. However, other reasons can also lead to low blood sugar. Here are some common causes of hypoglycemia:

  • Taking too much insulin or diabetes medicine
  • Skipping meals or eating less than usual
  • Exercising more than normal without eating enough
  • Drinking alcohol, especially without food
  • Certain illnesses, like severe infections
  • Rare hormone or enzyme problems
  • In the United States, most cases of hypoglycemia are linked to diabetes treatment. Still, anyone can experience low blood sugar under certain conditions.

    Recognizing the Symptoms of Hypoglycemia

    It is important to spot low blood sugar symptoms early. Quick action can prevent serious problems. Signs of hypoglycemia can be mild or severe. For example, you may notice these symptoms:

  • Shakiness or trembling
  • Feeling very hungry
  • Sweating more than usual
  • Feeling anxious or nervous
  • Dizziness or lightheadedness
  • Headache
  • Weakness or tiredness
  • Fast heartbeat
  • Confusion or trouble focusing
  • Irritability or mood changes
  • Sometimes, symptoms can get worse. If blood sugar drops very low, you might faint or have a seizure. Therefore, it is important to treat low blood sugar right away.

    When to Seek Medical Help

    Most of the time, mild hypoglycemia can be treated at home. However, you should get medical help if:

  • Your symptoms do not improve after eating or drinking sugar
  • You cannot eat or drink safely
  • You faint, have a seizure, or cannot wake up
  • You have frequent episodes of low blood sugar
  • In these cases, call your doctor or emergency services right away. Early treatment can prevent serious health problems.
