Dizziness

Light-headed, spinning or unsteady?

Dizzy covers several different feelings, and describing yours helps a doctor find the cause. Light-headedness feels like you might faint, often when you stand up quickly, are dehydrated or overheated, or have low blood sugar; sitting or lying down with your legs raised can help. Vertigo feels as if you or the room is spinning, often with nausea. Its most common cause is an inner ear problem called BPPV, brought on by moves such as rolling over in bed or looking up. Unsteadiness means trouble keeping your balance. Migraine can also cause dizziness (see headache).

Stroke signs, and medicines that can make you dizzy

Dizziness is occasionally a sign of stroke. Think F.A.S.T.: has the face drooped, can they lift both arms, is their speech slurred? If you see any of these signs, time is critical: call Triple Zero (000) straight away. Also call 000 for dizziness with chest pain or pressure, shortness of breath, numbness or weakness in the face, arm or leg, vision changes, trouble talking or swallowing, confusion or fainting. Some medicines can cause dizziness, including some blood pressure medicines, antidepressants, sedatives and anticonvulsants. A pharmacist can review your medicines, but don't stop or change one without checking first. For advice at any hour, call healthdirect on 1800 022 222.
