05FAQ
Questions about excessive sweating.
01What is hyperhidrosis?+
Hyperhidrosis is sweating beyond what the body needs to regulate temperature. It can affect specific areas such as the underarms, hands, feet, or face, or appear as more widespread sweating. The pattern matters because excessive sweating can also be caused by a medicine or another health condition.
Understand hyperhidrosis02How do I know if my sweating may be hyperhidrosis?+
Repeated sweating that affects both sides of a body area, began relatively early, happens at least weekly, and interferes with daily life can fit a primary focal pattern. These are clues, not a diagnosis. Sweating that starts suddenly, happens during sleep, affects much of the body, or is markedly one-sided deserves clinical evaluation.
Check how much sweating affects you03What causes excessive sweating?+
Sometimes excessive sweating is the condition itself. This is called primary hyperhidrosis. It can also be linked to a medicine, another health condition, or a physical change such as menopause. Ecrina cannot determine the cause, so new or unusual sweating should be reviewed by a clinician.
Compare primary and secondary patterns04What treatments are available for hyperhidrosis?+
Options include antiperspirants, prescription skin treatments, iontophoresis, injections, oral medicines, and procedures. There is no single best treatment for everyone. Body area, sweating pattern, severity, side effects, and treatment burden all affect the choice.
Compare treatment options05Do treatments differ for underarms, hands, feet, or face?+
Yes. Underarms have the broadest set of studied prescription and procedural options. Iontophoresis has controlled evidence for hands and feet, while treatments used near the face and eyes need extra care. Evidence for one body area should not automatically be applied to another.
Find guides for where you sweat06Can anxiety make excessive sweating worse?+
Stress and anxiety can make sweating more noticeable for some people, especially in areas already prone to it. But anxiety is not the only possible explanation, and it does not show whether sweating is primary or secondary. Look at the full pattern, including when it began, where it happens, and whether it occurs during sleep.
Understand the patterns that matter07Is hyperhidrosis genetic?+
Primary focal hyperhidrosis can run in families, but family history is only one clue. Current evidence does not establish one hyperhidrosis gene, a certain inheritance pattern, or a consumer DNA test that can diagnose it.
Read what family studies show08When should I see a clinician about excessive sweating?+
Get urgent medical help if sweating comes with chest pain, fainting, trouble breathing, fever, unexplained weight loss, or a rapid change in your health. See a clinician if it begins suddenly, happens mainly during sleep, affects much of your body, is markedly one-sided, or follows a medication change. You can also ask for help whenever sweating disrupts daily life.
