What causes excessive sweating under the armpits?

Under normal circumstances, excessive underarm sweating refers to frequent perspiration in the armpits. This condition is usually caused by emotional fluctuations, body temperature regulation, infections, hyperhidrosis, diabetes, and other factors. If discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:

1. Emotional fluctuations

When experiencing emotional changes, the sympathetic nervous system is activated, stimulating sweat glands to secrete sweat, resulting in frequent underarm sweating. Learning relaxation techniques such as deep breathing, meditation, and yoga may help regulate emotions.

2. Temperature regulation

The human body regulates its temperature through sweating in hot environments or after strenuous exercise. Since the armpits contain a high concentration of sweat glands, they naturally tend to sweat frequently. This is a protective mechanism to maintain normal body temperature. Keeping indoor temperatures comfortable, wearing breathable and sweat-absorbing clothing, and drying sweat promptly after exercise can help keep the underarms dry.

3. Infection

Infections are typically caused by invading bacteria, fungi, or other pathogens. Inflammation can stimulate sweat glands to produce more sweat, leading to persistent underarm sweating as a way to cleanse and expel pathogens. Symptoms may include local redness, swelling, and pain. Patients should follow medical advice and may be prescribed medications such as metronidazole tablets, azithromycin tablets, or cefixime tablets for treatment.

4. Hyperhidrosis

Hyperhidrosis is a condition characterized by abnormally increased sweating in localized or generalized areas of the skin. Abnormal sweat gland activity can lead to persistent underarm sweating, which may also be accompanied by excessive sweating of the palms and soles. Patients may take medications such as Acanthopanax senticosus tablets, vitamin B1 tablets, or oryzanol tablets as directed by a physician.

5. Diabetes

Diabetes results from absolute or relative deficiency in insulin secretion or impaired insulin utilization. Long-standing diabetes can damage the autonomic nervous system, disrupting normal regulatory functions of sweat glands and potentially causing abnormal sweating, including the symptoms described. Treatment should follow medical guidance and may include medications such as metformin hydrochloride tablets, glipizide tablets, or insulin aspart injection.

Maintain a healthy diet by avoiding spicy and irritating foods, and ensure regular hygiene and dryness of the body.
