Why do I sweat after eating?

It is normal to sweat while eating and sleeping when the weather is hot. This is because the sweat glands in the human body are in a state of diffusion, so sweating symptoms will naturally appear. However, if you sweat profusely when the weather is cold, you should consider that you are physically weak or lack of yang energy in your body, which requires timely examination.

Sweating is a physiological function of the human body to excrete and regulate body temperature, but if the sweating pattern, amount, color and smell of sweat change, it can be a precursor to certain diseases and should be taken seriously. The following is an explanation of some common sweating phenomena from the perspective of traditional Chinese medicine:

Spontaneous sweating

Frequent sweating that is not caused by hot weather, taking diaphoretics or other stimuli is called "spontaneous sweating". Spontaneous sweating is mostly caused by weak lung qi, weak Wei Yang, and leakage of body fluids, and is therefore often accompanied by symptoms of Yang qi deficiency such as fatigue, weakness, shortness of breath, and chills. It is more common in children with rickets and patients with hyperthyroidism.

Night sweats

You sweat when you fall asleep and stop sweating when you wake up. Night sweats are mostly caused by Yin deficiency. Yin deficiency leads to Yang hyperactivity. Yin cannot control Yang, and body fluid turns into sweat. Therefore, it is often accompanied by symptoms such as fever in the five parts of the body, insomnia, and dry mouth and throat. It is common in patients with pulmonary tuberculosis infiltration stage.

War sweat

That is, sweating followed by whole body shivering is a manifestation of the struggle between good and evil during the process of febrile disease. If the fever subsides after sweating, the pulse becomes calm and the body becomes cool, it means that the evil has gone away and the body is at peace, and the vital energy has recovered, which is a good phenomenon. If the limbs become cold and the patient becomes restless after sweating, it means that the body's health cannot overcome the negative energy and that the body's health becomes weaker, which is a serious symptom. War sweats are common in the early and middle stages of various infectious diseases.

No sweat

It refers to a critical condition, when the vital energy is weak and the Yang energy is about to be exhausted, the patient will sweat profusely, and is often accompanied by critical symptoms such as rapid breathing, cold limbs, weak pulse, and sometimes absent pulse. It is a sign that the Yang energy is about to be exhausted, and is more common in patients with heart failure and collapse.

Head sweat

Sweating is limited to the head. It is mostly caused by evil heat in the upper burner, or stagnation of damp heat in the middle burner, and is more common in Yangming heat syndrome and damp-heat syndrome. If it occurs after a serious illness, or in the elderly with shortness of breath and sweating on the forehead, it is mostly a symptom of deficiency. If a person suddenly breaks out in forehead with profuse sweat at the end of a serious illness, it is a dangerous sign that the yin is rising, the yin deficiency cannot attach to the yang, and the yin fluid is lost along with the qi. However, children often sweat on their heads when they sleep. If there are no other symptoms, it is not a sign of illness.

Partial sweating

Commonly known as "half-body sweat". It can be found on the left or right side, upper or lower body. They are all caused by wind-phlegm or rheumatism blocking the meridians, or insufficient nutrition and defense, or disharmony of Qi and blood. It is more common in patients with rheumatism or hemiplegia. If an elderly person sweats profusely, it may be a precursor to a stroke.
