What to do about Dizziness
Find out if your dizziness warrants a doctor’s visit

Dizziness is medically defined as a feeling of lightheadedness and unsteadiness. Additional symptoms may include feeling a loss of balance or vertigo. You may feel like the room is spinning. Although most causes of dizziness are not serious and quickly resolve themselves on their own, some bouts of dizziness can lead to indications of more serious problems.
Common Causes of Dizziness   
Lightheadedness typically occurs when there is not enough blood getting to the brain. If there is a sudden drop in your blood pressure or you are dehydrated because of excessive vomiting, diarrhea, fever, dizziness may also occur. Many people experience lightheadedness if they get up too quickly from a seated position, especially as they get older. Flu, common cold, or allergies are often accompanied by dizziness as well.
Lightheadedness can also signal the onset of more serious conditions, including heart problems (such as abnormal heart rhythm or heart attack), stroke, and severe drop in blood pressure (shock). However, you will usually have additional symptoms like chest pain, a feeling of a racing heart, loss of speech, change in vision, or other symptoms along with dizziness.
Additionally, vertigo is often caused by benign positional vertigo and labyrinthitis. Benign positional vertigo occurs when you switch the position of your head. Labyrinthitis is a condition that usually follows a cold or flu and is caused by a viral infection of the inner ear. Another common inner ear problem is Meniere's disease, which  causes vertigo, loss of balance, and ringing in the ears.
Rarely, vertigo or feeling unsteady might be a sign of seizures, a brain tumor, stroke, multiple sclerosis, or a bleeding in your brain. In such conditions, other symptoms usually accompany the sense of dizziness.
Minimizing dizziness
Avoid sudden changes in posture if you tend to get lightheaded when you stand up. Drink fluids if you are thirsty or lightheaded. You may need intravenous fluids if you are unable to keep fluids down from nausea or vomiting. These are delivered to you at the hospital.
Certain forms of vertigo can be reduced by working with a physical therapist. Medications from your doctor may help you feel better. If you want, you can try taking medications such as antihistamines, sedatives, or pills for nausea. Surgery may be necessary if you have Meniere's disease.
When to get emergency medical care:
• If the dizziness accompanies a head injury
• If the person suffers from a fever over 101°F
• If the dizziness is accompanied by convulsions or ongoing vomiting
• If the person also experiences chest pain, heart palpitations, shortness of breath, weakness, inability to move an arm or leg, or change in vision or speech
• If the person is fainting and losing consciousness for more than a few minutes
