Hypoglycemia: Causes, Symptoms, and What You Need to Know

When your hypoglycemia, a condition where blood glucose levels fall below normal, typically under 70 mg/dL. Also known as low blood sugar, it can hit fast and hit hard—shaking, sweating, confusion, even fainting. It’s most common in people with diabetes, a chronic condition where the body struggles to regulate blood sugar, but it doesn’t only affect them. Anyone on insulin, certain oral meds, or even skipping meals can slip into it.

Insulin, a hormone that helps cells absorb glucose from the bloodstream is often the culprit. Too much insulin, whether from an injection, medication, or the body overproducing it, pulls sugar out of the blood too fast. But it’s not just about insulin. Skipping meals, drinking alcohol on an empty stomach, or overdoing exercise without eating enough can trigger it too. People with blood glucose, the amount of sugar circulating in the bloodstream, critical for energy fluctuations from other conditions—like liver disease, hormone imbalances, or rare tumors—can also experience it. The body reacts quickly: heart races, hands tremble, mind feels foggy. Left untreated, it can lead to seizures or loss of consciousness.

You don’t need to guess if you’re having a low. Keep glucose tabs handy—glucose tablets, juice, or even candy. Know your warning signs: dizziness, hunger, irritability, blurry vision. Check your sugar if you can. If you’re helping someone who’s confused or passed out, don’t give them food or drink—call emergency help. Their body can’t process it safely. Prevention matters: eat regular meals, carry a snack, adjust meds with your doctor, and track patterns. If lows happen often, something’s off—maybe your dose is too high, or you’re not eating enough carbs. Don’t ignore it. Hypoglycemia isn’t just a nuisance; it’s a signal your body needs attention.
