Why do you always sweat when it's sultry?

Some people, especially in love sweating, often sweat profusely when eating meals or doing something in summer or winter, and sweat profusely when they are a little nervous. This disease is called hyperhidrosis in medicine.

Hyperhidrosis can be caused by febrile diseases, metabolic diseases and mental factors. In summer, the climate is hot and people are under high temperature. Hyperhidrosis is a normal phenomenon. If it is also the case under low temperature, it should be considered as a pathological condition.

There are mainly the following diseases that cause hyperhidrosis:

First, hypoglycemia.

There are many reasons for hypoglycemia. Sympathetic nerve hyperactivity can be the main manifestation during the attack. When the blood sugar suddenly drops, the sympathetic nerve is excited, and a large amount of adrenaline is released, which can lead to the patient's pale face, cold sweat, hand and foot tremor and so on.

the second is hyperthyroidism, which is called hyperthyroidism for short.

Fear of heat and excessive sweating is one of the characteristics of this disease, and it is also manifested as mental stress, personality change, irritability, inability to concentrate, difficulty in falling asleep and other symptoms. In addition, suffering from hyperthyroidism, increased appetite, eating more, but people lose weight. In hyperthyroidism, the gastrointestinal function is enhanced, and most patients have increased defecation times, and at the same time have symptoms such as palpitation and decreased work efficiency.

the third is pheochromocytoma.

The common symptom of chromaffin cells is sweating profusely. Sweating is paroxysmal, and sometimes it can continue to sweat, but facial flushing or whitening can occur at the same time during paroxysmal attacks. There will also be palpitations, hand tremors, cold limbs and so on. However, the onset of this disease is often accompanied by obvious blood pressure increase and headache symptoms caused by it.

the fourth is diabetes.

Diabetes mellitus is often accompanied by abnormal sweating due to autonomic dysfunction. But patients also have "three more and one less", that is, "eat more, drink more, urinate more and lose weight" It is generally not difficult to make a diagnosis by blood sugar test and urine sugar test.

.............................................................................

Sweating is a physiological function of human body to excrete and regulate body temperature. However, if the way of sweating, the amount, color and smell of sweat change, it can be regarded as a precursor of some diseases and should be paid attention to. The following is the explanation of some common sweating phenomena from the perspective of traditional Chinese medicine:

spontaneous sweating

It is not called "spontaneous sweating" because of the sweltering weather, taking sweating drugs and other stimulating factors. Spontaneous sweating is mostly caused by weak lung qi deficiency, weak defensive yang and leakage of body fluid, so it is often accompanied by symptoms of yang deficiency such as fatigue, fatigue, shortness of breath and fear of cold. It is more common in children with rickets and patients with hyperthyroidism.

night sweats

when you fall asleep, you sweat, but when you wake up, you stop sweating. Night sweats are mostly caused by yin deficiency, which leads to hyperactivity of yang, yin does not control yang, and body fluid is sweating, so it is often accompanied by symptoms such as five upset, insomnia, dry mouth and pharynx. It is common in patients with pulmonary tuberculosis infiltration.

war sweating

refers to sweating after shivering all over the body, which is a manifestation of the struggle between good and evil in the process of febrile diseases. It is a good phenomenon that the fever subsides after sweating, and the pulse is still and the body is cold, which means that the evil is gone and the vitality is restored. If the limbs are cold and fidgety after sweating, it means that the healthy qi is invincible, and the healthy qi goes down with weakness, which is a critical illness. War sweat is more common in the early and middle stages of various infectious diseases.

absolutely sweating

refers to severe illness, weakness of vital qi, and excessive sweating when the yang is about to take off, which is often accompanied by shortness of breath, cold limbs, weak pulse, and sometimes there is no equal danger. It is an image that the yang will be completely exhausted, and it is more common in patients with heart failure and collapse.

head sweating

sweating is limited to the head. It is mostly caused by pathogenic heat in the upper jiao or damp-heat stagnation and steaming in the middle jiao, which is more common in Yangming fever and damp-heat syndrome. If it is seen after a serious illness, or the elderly are panting and sweating, it is mostly deficiency. For example, sudden profusion of forehead sweat at the end of serious illness is a crisis in which deficiency of yin goes up, yin deficiency cannot attach to yang, and yin and body fluid take off with qi. However, children often sweat on their heads when they sleep. If there are no other symptoms, they are not symptoms.
