Hyperhidrosis (Excessive Sweating)- Symptoms, Causes and Treatment 

We all sweat while working out or in a hot and humid weather condition. This is perfectly normal. But there are people who sweat more than normal. This excessive sweating is called Hyperhidrosis. It may occur even in unusual situations like cold temperatures or in a relaxed non-working state. It can affect the whole body or certain areas like underarms (axillary hyperhidrosis), palms and soles of the feet (palmoplantar hyperhidrosis). Excess sweating, particularly in these areas, can be observed from the adolescent age itself. 

While normal sweating is alright, excess sweating can be embarrassing in many situations as your clothes get stained and people don’t prefer talking to you or being around you. Many of them do not seek treatment as they are not aware that hyperhidrosis is treatable. It may also be caused by underlying diseases like hyperthyroidism, so diagnosing hyperhidrosis is very important. Keep reading to find out the symptoms, causes and treatment of hyperhidrosis.
