Understanding Why You Sweat Excessively

Does everyday activity cause you to sweat more than usual? Do your palms become so damp before a handshake that you need a tissue? While this might seem inconvenient or embarrassing, excessive sweating could be a symptom of an underlying health issue. Recognizing the reasons behind this condition is essential for proper management.

What leads to excessive sweating?
Research indicates that hormonal imbalances, obesity, and infections can contribute to hyperhidrosis. However, not all cases are serious, and some may not be harmful.

Normal sweating helps regulate body temperature, but hyperhidrosis involves uncontrollable and excessive perspiration. It can be categorized into localized hyperhidrosis, affecting specific areas, or generalized hyperhidrosis, impacting the entire body.

Localized hyperhidrosis
This form affects about 1-3% of people, typically beginning in adolescence or late childhood. It isn't necessarily tied to medication or disease but results from minor nervous system irregularities.

Understanding whether your sweating is localized or generalized is key to determining its severity and potential causes.

Generalized hyperhidrosis
This more severe type causes pervasive sweating across the whole body and often signals an underlying health issue. Night sweats are common in this case. Causes can include thyroid problems, diabetes, menopause, pregnancy, or neurological conditions like Parkinson’s disease. It may also relate to cardiovascular or autoimmune disorders.

If you cannot identify the cause, consulting a healthcare professional is advised for proper diagnosis and treatment.
