Hyperhidrosis
Mild
Hyperhidrosis is a condition in which a person sweats excessively and unpredictably, even when the body does not need to cool itself. Sweating may be particularly noticeable on the hands, feet, underarms, face, or other areas. Primary hyperhidrosis often affects specific areas and may occur without another underlying disease. Excessive sweating can interfere with daily activities, work, social situations, and emotional well-being.

When to Seek Medical Attention
Hyperhidrosis is usually not an emergency but may require medical evaluation when excessive sweating is persistent or interferes substantially with daily activities. Seek assessment when sweating is new, unexplained, occurs during sleep, or is accompanied by other symptoms. Sudden heavy sweating with chest pain, shortness of breath, fainting, or severe illness requires urgent medical attention.

Overview
Hyperhidrosis is a condition in which a person sweats excessively and unpredictably, even when the body does not need to cool itself. Sweating may be particularly noticeable on the hands, feet, underarms, face, or other areas. Primary hyperhidrosis often affects specific areas and may occur without another underlying disease. Excessive sweating can interfere with daily activities, work, social situations, and emotional well-being.
Symptoms 1
Cold Intolerance
Causes 3
Primary hyperhidrosis is usually associated with overactive sweat glands, and in many cases no specific cause is identified. It may run in families. Secondary hyperhidrosis occurs when excessive sweating is related to another medical condition or a medicine. Possible associated conditions include infections, hormone disorders, neurologic conditions, low blood sugar, and other illnesses. Some medicines can also cause increased sweating.
Genetics
Obesity
Stress
Risk Factors
A family history of excessive sweating can increase the likelihood of primary hyperhidrosis. Primary focal hyperhidrosis commonly begins during childhood or adolescence, although it can occur later. Risk for secondary hyperhidrosis depends on the presence of an underlying medical condition or use of a medicine that affects sweating. Anxiety or emotional stress may worsen sweating, although they are not necessarily the underlying cause of primary hyperhidrosis.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on the pattern, location, duration, and severity of excessive sweating and whether it occurs without normal triggers such as heat or exercise. A physical examination and medical history can help distinguish primary from secondary hyperhidrosis. When another condition is suspected, blood or urine tests may be used to evaluate possible causes. In selected cases, tests that measure sweating may help document the amount and distribution of perspiration.
Prevention
Key Prevention Tips
Primary hyperhidrosis cannot always be prevented because its exact cause is often unknown
Avoiding known triggers such as excessive heat, certain foods, or stressful situations may reduce episodes in some people
Good skin hygiene and breathable clothing can help manage moisture and reduce skin irritation
When excessive sweating begins suddenly or is accompanied by other symptoms, medical evaluation is important because treating an underlying condition or changing a causative medicine may address secondary hyperhidrosis
