What Are the Causes of Excessive Sweating in the Armpits?

There are mainly two reasons for excessive underarm sweating. One is physiological reasons, such as excessive heat, poor personal hygiene, and poor breathability of clothing. Of course, we should also be alert to some diseases. Some systemic diseases can easily lead to excessive underarm sweating. In this case, timely examination should be carried out in hospitals to avoid excessive harm to health. What are the causes of excessive underarm sweating? Let's take a brief look.

1. Systemic diseases are caused by systemic diseases, such as endocrine disorders (thyroid hyperfunction, diabetes, pituitary hyperfunction, etc.), nervous system diseases, some infectious diseases (malaria, tuberculosis, etc.), and long-term illness causing physical weakness. As long as these systemic diseases are controlled, the situation of excessive sweating can be resolved. Hyperhidrosis is caused by excessive secretion of eccrine glands, manifesting as excessive sweating in the whole body (generalized hyperhidrosis) or locally (localized hyperhidrosis). Hyperhidrosis can be secondary to some mental and neurological diseases, metabolic diseases, endocrine disorders, tumors, drugs, etc., which is called secondary hyperhidrosis.

2. Mental reasons are mental sweating caused by high tension and emotional excitement due to sympathetic nerve imbalance. Taking some sedatives (such as atropine, probenecid, belladonna mixture, etc.) temporarily helps, but it may have side effects such as dry mouth.

3. Physiological reasons are gustatory sweating, which is another physiological phenomenon. For example, sweating caused by eating some stimulating foods (chilli, garlic, ginger, cocoa, coffee) generally does not require treatment, but only dietary restrictions. When the condition is severe, it not only affects the patient's work, life, and learning, but may also cause psychological barriers and prevent them from participating in normal social interactions. Localized excessive sweating can be caused by sympathetic nerve damage or abnormal responses, which lead to an increase in the secretion of acetylcholine and excessive secretion of eccrine glands.
