Hypotension

Hypotension is a condition characterized by blood pressure being reduced or below normal levels. The symptoms of hypotension, or low blood pressure, include dizziness, fainting, palor, a feeling of coldness, and shock. The presence of hypotension may itself cause depression, lethargy, and fatigue. Hypotension may be caused by some medications; however, causes that are more serious include peripheral neuritis, diabetes mellitus, tabes dorsalis, and Parkinson's disease.

Typically, hypotension corrects itself spontaneously. When the condition does not resolve on its own, improvement may be seen through the addition of salt to the diet to increase blood volume and the use of corticosteroids. When the cause is peripheral neuritis, treatment of this condition is required to correct the low blood pressure.
