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.\nSometimes, the lightheadedness 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 lightheaded 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.\n\nCauses of Dizziness\nSometimes, dizziness is used to describe vertigo, a motion and balance issue usually caused by an inner ear disorder. Vertigo is a feeling that you’re standing still but the world around you is spinning or tilting. Both vertigo and dizziness can cause nausea or vomiting when severe.\nOccasional dizziness can be caused by:\n\n\nA quick drop in blood pressure (like when you stand up too fast)\n\n\nAllergies\n\n\nIllness or infection\n\n\nDehydration\n\n\nAnxiety or stress\n\n\nHeavy periods\n\n\nSome medications\n\n\nAnemia (low iron)\n\n\nAlcohol and tobacco can also cause you to feel lightheaded from time to time. Changing your diet, drinking more water, and treating any illnesses or allergies may help resolve your symptoms.\nHow to Tell When Dizziness May Be Serious\nDizziness alone is often not much cause for concern, especially if it passes after a few moments. However, if you experience additional symptoms or fainting, you should talk to your doctor.\nIf you experience vomiting, double vision, or trouble using your arms or legs, you should get immediate medical attention. In fact, lightheadedness, along with shortness of breath, back pain, and fainting, are more common signs of heart attack in women than chest pain.\nOther signs that your dizziness might be a sign of something more serious:\n\nChest pain\nFever\nShortness of breath\nTrouble walking\nFalling\nStiff neck\nSigns of a stroke\n\nPreventing Dizziness\nLeading a healthy lifestyle, limiting smoking, and maintaining a healthy weight can help lessen the feeling of dizziness and help prevent more serious problems.
