Many of us become dizzy from time to time. You stand up too quickly and feel dizzy. You skip lunch and feel lightheaded by late afternoon. Sometimes, the lightheadedness in the body parts may be so strong you feel like you’re going to pass out. Dizziness is a catch-all term used to describe many feelings of being changeable or off-balance. Usually, it’s a minor issue that resolves when you lie down. However, if you have other symptoms that accompany the dizziness, it may be a sign of something more serious.
Low blood sugar
“When you don’t have enough blood sugar, every system in your body goes on reserve to use as little energy as possible, counting your brain, making you feel lightheaded or confused,” says Dr. Grossman. It may only take a drink of juice to relieve your symptoms, but it’s best to get your blood sugar levels analyze, especially if you need more glucose (sugar) in intravenous or pill form.
Heart attack and stroke
Other symptoms of a heart attack often accompanying lightheadedness are chest pain, shortness of breath, nausea, arm pain, back pain, or jaw pain. Symptoms suggesting a stroke are the sudden onset of headache, numbness, weakness, visual changes, trouble walking, or slurred speech. “But in older adults, lightheadedness may be the only symptom of a heart attack or a stroke, especially if it doesn’t go away,” says Dr. Grossman. In that case, every second counts, so get to an emergency room for treatment.
