Dizziness can also be a symptom of stress or anxiety, high blood pressure, diabetes, heart disease, or internal bleeding. A cold , allergies , or a virus infection may also produce dizziness. Some medications, particularly birth control pills and large doses of amphetamines, have dizziness as a side effect. Dizziness may also follow a concussion or violent shock to the brain . One type of dizziness, called positional vertigo , happens when you stand up or turn your head suddenly.
Some people develop a tendency toward positional vertigo as they age.
This happens because nerve impulses travel to the brain more slowly in old age. Some medicines have positional vertigo as a side effect. When you feel vertigo , sit still and keep your eyes fixed on an object that is also still. For other forms of dizziness, sit with your head between your knees to increase the blood flow to your brain . See your physician if your dizziness is particularly bad or if you become dizzy frequently.
