What causes Hyperhidrosis?
Sweating helps the body stay cool. In most cases, it is perfectly natural. People sweat more in warm temperatures, when they exercise, or in response to situations that make them nervous, angry, embarrassed, or afraid.
However, excessive sweating occurs without such triggers. Those with hyperhidrosis appear to have overactive sweat glands. The uncontrollable sweating can lead to significant discomfort, both physical and emotional.
When excessive sweating affects the hands, feet, and armpits, it's called primary or focal hyperhidrosis.
If the sweating occurs as a result of another medical condition, it is called secondary hyperhidrosis. The sweating may be all over the body, or it may be in one area. Conditions that cause second hyperhidrosis include:
Acromegaly Anxiety conditions Cancer Carcinoid syndrome Certain medications and substances of abuse Glucose control disorders Heart disease Hyperthyroidism Lung disease Menopause Parkinson’s disease Pheochromocytoma Spinal cord injury Stroke Tuberculosis or other infections </s>
