What are the signs and symptoms of hypoglycemia (low blood sugar)?
Symptoms of hypoglycemia can start quickly, and they can vary from person to person. One person can also experience different symptoms for each episode. The signs of hypoglycemia are unpleasant. But they provide good warnings that you should take action before your blood sugar drops more. The signs include: Shaking or trembling. Weakness. Sweating and chills. Extreme hunger (polyphagia). Faster heart rate. Dizziness or lightheadedness. Confusion or trouble concentrating. Anxiety or irritability. Color draining from your skin (pallor). Tingling or numbness in your lips, tongue or cheeks. Signs of severe hypoglycemia include: Blurred or double vision. Slurred speech. Clumsiness or difficulty with coordination. Being disoriented. Seizures. Loss of consciousness. Severe hypoglycemia is life-threatening. It needs immediate medical treatment. In rare cases, severe hypoglycemia that isn’t treated can result in a coma and/or death. You can also experience low blood sugar while sleeping (nocturnal hypoglycemia). Symptoms may include: Restless sleep. Sweating through your pajamas or sheets. Crying out during sleep. Having nightmares. Feeling tired, disoriented or confused after waking up.
