Sweating must be divided into physiological sweating and pathological sweating. Pathological sweating is the cause of hyperhidrosis, which is generally the manifestation of central nervous system dysfunction. Chinese medicine believes that sweating is caused by yin-yang imbalance. Whether it is hot or cold, even in winter, some people sweat a lot, and some people sweat profusely. If they exercise a little or eat something, they will sweat all over. What is the reason? There are two kinds of sweating.
(1) Normal physiological phenomena during metabolism. For example, 1, children have vigorous metabolism during their growth and development, and produce relatively more heat and waste, so they sweat more than adults. 2. The child's nervous system development is not sound enough. The sympathetic nerve that manages the secretion of sweat glands loses control of the brain during sleep, which is prone to temporary excitement, leading to excessive sweating, which will slowly disappear after two or three hours. This situation is common in children aged 3-6, and will gradually disappear with age.
(2) Pathological hyperhidrosis. There are medical classification rules for sweating, including spontaneous sweating, night sweats, head sweats, half-body sweats, hand, foot and heart sweats, etc. The most common are spontaneous sweating and night sweats. The so-called spontaneous sweating is involuntary sweating for no reason, usually in an environment where it is not hot and does not exercise during the day. Night sweats are medically considered to be sweating when you fall asleep at night and stop sweating after waking up. Of course, there are many other sweating situations that are classified. Spontaneous sweating and night sweats are partly pathological in medicine and combined with some diseases. Sometimes it is related to the disorder of the central nervous system in the body. Spontaneous sweating is related to many diseases, such as fever, pneumonia, rheumatic fever and so on. In addition, there are some causes of endocrine disorders, such as menopausal syndrome, and some metabolic diseases, such as hyperthyroidism. There are also some common diseases such as diabetes, hypoglycemia or coronary heart disease, pain and hypoxia. There is also sweating caused by drugs, such as taking aspirin. So there are still many reasons for spontaneous sweating. Rickets caused by calcium deficiency in children will lead to more sweating at night, accompanied by symptoms such as grumpy, easy to wake up, protruding forehead and late teething. Anemia, rheumatism and malnutrition can all lead to excessive sweating. Caused by epidemic febrile diseases, metabolic diseases and mental factors.
Hypoglycemia: it can lead to pallor, cold sweat, tremor of hands and feet, etc.
Hyperthyroidism: In addition to being afraid of heat and sweating, patients also show symptoms such as increased appetite, overeating, emaciation, increased stool frequency, palpitation and mental stress.
Diabetes: Due to autonomic nerve dysfunction, sweating often increases abnormally, and patients are accompanied by symptoms such as overeating, polyuria and weight loss.
Pheochromocytoma: The common symptoms are profuse sweating, paroxysmal sweating, and sometimes persistent sweating, as well as palpitation, shaking hands and cold limbs. And the attack is often accompanied by obvious blood pressure increase.
In addition, patients with hypertension and menopausal women will also have hyperhidrosis.
Spontaneous sweating: sweating during the day, especially after exercise, is mostly caused by qi deficiency or yang deficiency, and can be adjusted by taking warm tonic drugs.
Night sweats: sweating after falling asleep and stopping after waking up, which is more common in people with yin deficiency and excessive fire, especially those with pulmonary tuberculosis.
Nose sweat: Every time you sweat when you are emotional, nervous, tired from work or talk too much, sweat will seep from both sides of your nose and nose. More common in allergic rhinitis and low immunity, easy to catch a cold.
Sweating on the forehead: Sweating is confined to the head and forehead, and even sweating seems steaming, which is more common in people with excessive yang and excessive digestion.
Half body sweating: refers to half body sweating, while the other half body sweating little or nothing. It is more common in young patients with hypertensive encephalopathy, renal hypertension, stroke, hemiplegia and paraplegia. Hemiplegia can be caused by diseases such as paraplegia, bilateral limb imbalance or paraplegia. Traditional Chinese medicine believes that this is caused by poor circulation of qi and blood and poor meridians.
Fatigue sweat: refers to excessive sweating in the heart pit and middle part of the breast, which is caused by excessive anxiety, thinking, shock and fear. Common in overworked intellectuals.
Perspiration in perineum: Perspiration is confined to perineum and external genitalia, which is common in gynecological diseases such as vulvar itching and vaginitis, and there may also be perineum sweating with peculiar smell.
Sweat under the armpit: Sweat smells like body odor, which is caused by abnormal secretion of sweat glands under the armpit. More common in youth and middle age, women are more than men.
Half-head sweating: the whole head is divided into two parts by the nose, half of which sweats and the other half does not sweat. This is caused by the husband and wife sharing the same room after a serious illness, yin and yang deficiency, and feeling cold.
Sweat on hands, feet and heart: It usually occurs when you are nervous or excited or when you speak in public. It mostly occurs in teenagers and is mostly caused by mental depression.
