Sweaty hands and feet

Introduction The hand and foot hyperhidrosis is mainly manifested in the palm of the hand and sweaty on the soles of the feet. Mild patients only show wet palms, and severe palms can secrete sweat visible to the naked eye. When sweating, the palms are cold, and only a few patients can keep their fingers warm when sweating.

Patients often have sweating in the palms and other parts from childhood or adolescence, affecting daily life and work. Excessive sweating in the hands easily affects the flexibility of hand operation, interferes with manual operations, and the patient influences interpersonal interactions by avoiding shaking hands with others, and creates a state of evasion and anxiety. The survey showed that 50% of patients felt insufficient self-confidence and 38% had frustration. The patient with a sense of depression also reached about 20%.

Cause

Systemic hyperhidrosis can be an abnormal physiological reaction, or one of the symptoms of certain diseases such as hyperthyroidism and diabetes. Local hyperhidrosis may result in increased secretion of choline acetate due to sympathetic nerve damage or abnormal reaction, resulting in excessive sweat secretion by the small sweat glands. Patients often have sweating in the palms and other parts from childhood or adolescence, affecting daily life and work. Excessive sweating in the hands easily affects the flexibility of hand operation, interferes with manual operations, and the patient influences interpersonal interactions by avoiding shaking hands with others, and creates a state of evasion and anxiety.
