Dizziness may be the result of too much or too little blood in the brain. It is a very frequent symptom of indigestion, being often caused by gas in the stomach. By pressure of the distended stomach upon the aorta, it interferes with the circulation of the blood in the lower extremities and causes congestion of the head. The use of tobacco, tea and coffee, and alcohol, are frequent causes of severe, obstinate vertigo. This is especially true of tobacco. Exposure to great heat, either of the sun or other artificial sources, is a cause which is especially active in hot weather. Malaria sometimes produces vertigo. Loss of sleep, overwork, sexual excesses and abuses, and inhalation of impure air are very frequent causes. A few cases have been observed in which most obstinate vertigo was produced by disease of the ear. It has also in some cases depended upon diseases affecting the heart, brain, spine, kidneys, liver, or sexual organs.

The Treatment of Vertigo

Attention to all the laws of hygiene, avoidance of the known causes, employment of a simple unstimulating diet comprising but a very small portion of meat, constitute the main essentials of the treatment of obstinate vertigo. When it is induced by congestion, a hot foot-bath should be employed with cold applications to the head, and the patient should sleep at night with his head elevated, and should avoid stooping. When the symptom is due to the opposite condition of the blood-vessels of the brain, or anaemia, the patient should remain in a horizontal position as much as possible, and should avoid rising suddenly from a recumbent or sitting posture. Upon the approach of an attack of vertigo, he should lie down at once, or bend the body forward with the head between the knees. Such other measures should be employed as are recommended for cerebral anaemia.
