What Causes Excessive Sweating?
There are many factors that can be attributed to excessive sweating. As a dermatologist, Dr. Weishar distinguishes between the two types of hyperhidrosis – primary and secondary, to ensure that your hyperhidrosis treatment is specific to the cause thereof.
Primary Focal Hyperhidrosis
Primary focal hyperhidrosis is a medical condition characterized by excessive sweating on certain parts of the body, such as the hands, feet, underarms and head. Unlike other forms of excessive sweating, primary focal hyperhidrosis is not caused by another medical condition or medication side-effect. It tends to affect both sides of the body equally (in a “symmetric” pattern), and usually produces more sweat in specific “focal areas”. For example, people with sweaty palms often have concurrent excessive sweating in their feet as well. It usually begins in childhood or adolescence.
Secondary Generalized Hyperhidrosis
Secondary generalized hyperhidrosis is a type of excessive sweating that is caused by an underlying medical condition, or by taking certain medications. As its name implies, the hallmark of secondary hyperhidrosis is generalized sweating on multiple areas of the body, including the face, chest and back. It can also be accompanied by night sweats while sleeping.
