Dizziness is a term used to describe when you are feeling woozy, or faint. Vertigo, a symptom of dizziness, is the feeling that the room is spinning around you. When people experience dizziness, it may be a symptom showing the balance mechanism in your inner ear is not working properly.

What causes dizziness?

Circulation: If your brain does not get enough blood flow, you feel lightheaded. Almost everyone has experienced this on occasion when standing up quickly from a lying down position. But some people have light-headedness from poor circulation on a frequent or chronic basis. This could be caused by arteriosclerosis or hardening of the arteries, and it is commonly seen in patients who have high blood pressure, diabetes, or high levels of blood fats (cholesterol). It is sometimes seen in patients with inadequate cardiac (heart) function, hypoglycemia (low blood sugar), or anemia (low iron). Certain drugs also decrease the blood flow to the brain, especially stimulants such as nicotine and caffeine.

Vertigo refers to the sensation of being in a spinning environment. At rest, continuous and balanced signals from the peripheral vestibular system keep the eyes stationary via connections in the brain. When the head moves, a physiological imbalance in the signals leads to small movements of the eyes that keep vision optimal. When a sudden abnormality in the balance of the signals occurs, the result is a pattern of eye movements referred to as nystagmus.

The most common causes of vertigo are benign positional vertigo and labyrinthitis. Benign positional vertigo is vertigo that happens when you change the position of your head. Labyrinthitis usually follows a cold or flu and is caused by a viral infection of the inner ear. Meniere's disease is another common inner ear problem. It causes vertigo, loss of balance, and ringing in the ears.

Much less commonly, vertigo or feeling unsteady is a sign of stroke, multiple sclerosis, seizures, a brain tumor, or a bleed in your brain. In such conditions, other symptoms usually accompany the vertigo or imbalance.

Dizziness Symptoms

Extremities (arms and legs): tingling, weakness, clumsiness or weakness, fast, slow, or irregular pulses

Chest: pain (tightness, squeezing, burning, or pressure), shortness of breath, palpitations, jaw pain

Dizziness: Treatment

Treatment is determined by the underlying cause. If an individual has a cold or influenza, a few days of bed rest is usually adequate to resolve dizziness. Other causes of dizziness, such as mild vestibular system damage, may resolve without medical treatment.

If dizziness continues, drug therapy may prove helpful. Because circulatory problems often cause dizziness, medication may be prescribed to control blood pressure or to treat arteriosclerosis. Sedatives may be useful to relieve the tension that can trigger or aggravate dizziness. Low blood sugar associated with diabetes sometimes causes dizziness and is treated by controlling blood sugar levels. An individual may be asked to avoid caffeine, nicotine, alcohol, and any substances that cause allergic reactions. A low-salt diet may also help some people.

Dizziness is lightheadedness, feeling like you might faint, being unsteady, loss of balance, or vertigo. Dry heaves when it is at its worst. The nausea is worse in the morning and is aggravated by moving and somewhat alleviated by eating. More serious conditions that can lead to lightheadedness include heart problems (such as abnormal heart rhythm or heart attack), stroke, and severe drop in blood pressure (shock). Common symptoms of dizziness associated with aging include lightheadedness, a spinning sensation, giddiness, wooziness, or unsteadiness. Dizziness may be just mildly annoying or caused by something possibly life threatening. Lightheadedness is a feeling that you are about to faint or "pass out. Nausea is the body's way of reacting to an infection or condition.

Always carry a "sipper" cup filled with your favorite drinks. Dizziness and vertigo caused by a vestibular migraine may be triggered by turning your head quickly. Brain causes. Stroke, tumor, headaches, migraines, hyperventilation. Fainting (syncope) - A loss of blood supply to the brain causing loss of consciousness, typically after loss of blood output by your heart. Dementia or senility - Any illness causing confusion or changed state of mind, such as medications, drugs, or alcohol. Many things may trigger this infamous "common faint"—emotions, rapidly assuming an upright position, even urination. Promptly treat ear infections, colds, flus, sinus congestion, and other respiratory infections. This may help prevent labyrinthitis and Meniere's disease.

Nausea and vomiting can occur in both children and adults. Nausea is often indicative of an underlying condition elsewhere in the body. Nausea is also an adverse effect of many drugs. Nausea may also be an effect of a large intake of sugary foods. Nausea is the sensation that there is a need to vomit. Nausea can be acute and short-lived, or it can be prolonged. Nausea and vomiting can sometimes be symptoms of more serious diseases such as heart attacks, kidney or liver disorders, central nervous system disorders, brain tumors, and some forms of cancer. It is estimated that 50 to 90 percent of pregnant women experience nausea, while 25 to 55 percent experience vomiting. It often occurs with or precedes vomiting, but both nausea-without-vomiting and vomiting-without-nausea are possible.
