Hypoglycemia, or low blood sugar, can be dangerous. It occurs when your body uses up glucose too fast or it gets into your bloodstream too slowly. Undereating can mean not enough glucose is available in the first place, and can also be a cause. Drinking alcohol significantly increases your risk for hypoglycemia.
Here are some signs you’re hypoglycemic:
- Sudden weakness or jitteriness, particularly in the arms or legs.
- Moodiness, or feeling overwhelmed, frustrated, angry or irritated. You may feel like you want to cry for no reason.
- Breaking into a cold sweat.
- Nausea and hunger.
- Slurring and confusion, or spacing out.
If you have these symptoms, try eating something, especially if you’re diabetic and on insulin therapy. Sugary food will help in the short term but could cause the condition to recur, so eat something more balanced about 15 minutes later. Do not drive in this condition; if you’re drinking, stop. Hypoglycemia can also be a result of a serious illness, so if you’re experiencing these symptoms regularly, talk to a doctor.
