What are the reasons for excessive sweating in the palms and armpits?

Under normal circumstances, excessive sweating in the palms and armpits may be caused by emotional fluctuations, high-temperature stimulation, hyperhidrosis, hyperthyroidism, diabetes, or other reasons. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analysis is as follows:

1. Emotional fluctuations: When feeling nervous or anxious, the sympathetic nervous system becomes excited, stimulating increased sweat secretion from glands in the palms and armpits. Regulating emotions through deep breathing, meditation, and similar methods can help prevent extreme emotional changes. After sweating, use a clean towel to wipe the area promptly and keep it dry.

2. High-temperature stimulation: When exposed to high temperatures for prolonged periods or after intense physical activity, the body increases sweat production to dissipate heat. Reduce time spent in hot environments, wear breathable clothing during exercise, carry absorbent tissues, and promptly wipe away sweat.

3. Hyperhidrosis: Overactive local sweat glands can lead to hyperhidrosis, causing significantly more sweating in the palms and armpits than normally required. Patients may apply medications such as aluminum chloride solution, methenamine solution, or formaldehyde solution topically as directed by a physician to reduce sweat secretion.

4. Hyperthyroidism: Excessive thyroid hormone secretion accelerates metabolism, leading to generalized sweating, particularly noticeable in the palms and armpits. Patients should take antithyroid medications such as methimazole tablets, propylthiouracil tablets, or carbimazole tablets as prescribed to control thyroid hormone levels.

5. Diabetes: Fluctuations in blood glucose levels or diabetic neuropathy can disrupt autonomic nerve function, resulting in excessive sweating in the palms and armpits. Patients should manage their blood sugar with medications such as insulin injection, glimepiride tablets, or metformin tablets as directed by a healthcare provider, helping stabilize metabolic function.

In daily life, choose loose-fitting, breathable cotton clothing and avoid synthetic or tight garments. Maintain a light diet, reduce intake of spicy and irritating foods, and avoid alcohol consumption. Keep a regular sleep schedule and avoid staying up late, which helps maintain stable endocrine function.
