What causes excessive sweating in the armpits?

If you have excessive sweating in your armpits, you should pay attention to whether it is caused by hyperhidrosis. Hyperhidrosis is mainly caused by excessive secretion of the eccrine sweat glands, and the common symptom is abnormally excessive sweating. Mental and neurological diseases or endocrine disorders can also cause symptoms of excessive sweating.

One is caused by systemic diseases, such as endocrine disorders (hyperthyroidism, diabetes, hyperpituitarism, etc.), nervous system diseases, some infectious diseases (malaria, tuberculosis, etc.) and long-term illness causing physical weakness. Excessive sweating can be resolved as long as these systemic diseases are controlled.

The second is psychogenic sweating, which is caused by high tension and emotional excitement, and is due to sympathetic nervous system disorders. Taking some sedatives orally (such as atropine, propantheline, belladonna mixture, etc.) has a temporary effect, but has side effects such as dry mouth.

The third is gustatory sweating, which is another physiological phenomenon, such as sweating caused by eating certain irritating foods (chili, garlic, ginger, cocoa, coffee). This situation generally does not require treatment, only dietary restrictions.

4. Hyperhidrosis is caused by excessive secretion of the eccrine sweat glands, which manifests as abnormally excessive sweating throughout the body (generalized hyperhidrosis) or locally (localized hyperhidrosis). Hyperhidrosis can be secondary to certain mental and neurological diseases, metabolic diseases, endocrine disorders, tumors, drugs, etc., which is called secondary hyperhidrosis; the cause of primary hyperhidrosis is unknown, the most common sites of occurrence are the palms, armpits and soles, and occasionally occur in the head and neck, trunk and calves. The age of onset is mostly from childhood, worsens in adolescence and accompanies life. When the condition is serious, it not only affects the patient's work, life and study, but may even cause psychological disorders in the patient and make him afraid to participate in normal social activities.
