Primary focal hyperhidrosis causes people to sweat excessively in a localised area such as their palms. Although it is classified as a medical condition, sweaty palms are not generally a sign of disease and will not affect a person’s health.
Symptoms tend to be symmetrical, affecting both sides equally. Primary focal hyperhidrosis is thought to stem from a malfunction in the nervous system.
While the condition isn’t medically dangerous, it can cause issues in a person’s quality of life. Some people tend to dodge certain social situations to avoid exposing themselves to others.
