Why Do I Feel Lightheaded?

why do i feel light headed

The words dizziness and lightheadedness are used to describe similar symptoms, but they are different. Dizziness is a feeling of unbalance or the threat of fainting, while lightheadedness refers to the fact that you cannot keep your balance. People with lightheadedness often experience unsteadiness, sweating, or a sense of heavyness in their body. It may even affect their vision. A lack of blood to the brain may cause a person to become lightheaded. While lightheadedness is not usually a cause for concern, it can be a sign of a serious medical problem.

Certain medications may be the cause of lightheadedness. Medications that lower blood pressure or make you urinate more frequently can cause lightheadedness. These drugs are known diuretics and can cause fainting spells. However, adjusting the dosage or switching to a different drug can help you avoid the lightheadedness. It’s important to contact your doctor as soon as you experience lightheadedness, as it may be an early symptom of a stroke.

Vertigo, or spinning sensation, can be a sign of inner ear problems or an imbalance in your central nervous system. In most cases, this type of vertigo is caused by a problem with the inner ear and can occur as a side effect of certain medications. While lightheadedness should pass on its own within a few minutes, persistent dizziness is a warning sign of a serious medical condition, and should be investigated by your doctor.
