Why do my hands, feet and armpits sweat so much?

For many people, summer is actually quite uncomfortable because they experience excessive sweating in their hands, feet and armpits. This situation not only makes them feel hot and uncomfortable, but also puts them in embarrassing situations in some public places. So, what is the reason for excessive sweating in their hands, feet and armpits?

1. Primary hyperhidrosis : refers to the state of hypersecretion of sweat glands without obvious reasons. It is a phenomenon of excessive secretion of sweat glands caused by autonomic nervous function disorder. The most obvious symptom is localized sweating. Hyperhidrosis of the hands belongs to this category, which is caused by the excessive activity of the sympathetic nerves that control the sweat glands in the hands, armpits, and soles of the feet. There is a familial susceptibility, presenting an autosomal dominant inheritance trait, and it may be passed on to offspring.

2. Secondary hyperhidrosis : Hyperhidrosis symptoms are caused by some neuroendocrine and other systemic diseases (such as hyperthyroidism, diabetes, hypoglycemia, cardiovascular disease, respiratory failure, etc.). The most obvious symptom is systemic sweating.

3. First of all, we should rule out whether the excessive sweating of hands and feet is caused by disease . Generally speaking, diabetes, hyperthyroidism, hypertension, congestive heart failure, hemiplegia, spinal trauma, tumors, tuberculosis, etc. can cause abnormal sweating and be accompanied by obvious corresponding symptoms. In this case, it is necessary to control the condition promptly and then the excessive sweating can be resolved. In addition to the above situations, there are some other manifestations of sweating, such as changes in sweat color, including yellow sweat, red sweat, black sweat, etc. This situation requires a doctor to make a comprehensive judgment and then diagnose and treat it. If a seriously ill patient suddenly breaks out in a sweat, has cold limbs, weak or heavy sweating, or has rapid breathing, etc., it indicates that the condition is very serious.

4. Humans have two types of sweat glands . One type is small and distributed throughout the body. Its main function is to sweat and regulate body temperature. The other type is larger, called apocrine glands, which are distributed in special areas such as the armpits and pubic area, with the most glands in the armpits. The fluid secreted by the apocrine glands is originally an odorless liquid, but when the fluid is decomposed by the bacteria retained in the armpits, it becomes a smelly liquid, commonly known as "body odor". Patients with excessive underarm sweating are prone to bacterial growth, and the odor is particularly strong, causing great trouble to their lives.
