What causes excessive sweating under the armpits?

Under normal circumstances, excessive underarm sweating is caused by physiological factors, but it may also be related to pathological conditions such as bromhidrosis or hyperhidrosis. Doctors should select targeted treatment measures based on the specific underlying cause and promptly manage symptoms to prevent progression. The details are as follows:

1. Physiological Factors

After intense physical activity, nerve cells send signals to the hypothalamus, activating sweat glands and resulting in underarm sweating and fatigue. Symptoms typically resolve spontaneously with appropriate rest and do not require special treatment.

2. Pathological Factors

1) Bromhidrosis

Influenced by hot weather, genetics, or other factors, apocrine glands in the armpits may become infected with diphtheroid bacteria, leading to unpleasant odor and excessive sweating. Patients should maintain dryness and cleanliness of the armpits. In severe cases, treatments such as laser therapy or electroacupuncture may be used according to medical advice to promptly alleviate discomfort.

2) Hyperhidrosis

Long-term heavy alcohol consumption or chronic stress may affect overall health, causing excessive sweating, eczema, and similar symptoms in areas such as the underarms, limbs, and back. Treatment may include medications such as oryzanol tablets, chlorpromazine hydrochloride tablets, or propranolol hydrochloride tablets under a doctor's guidance. Skin hygiene should be maintained during medication.

In addition, conditions such as diabetes or hyperthyroidism may also contribute to excessive sweating. It is advisable to engage in moderate exercise regularly, avoid prolonged high-intensity workouts, and seek timely medical care when symptoms occur.
