The liver is an important organ of the body, but also one of the more fragile and susceptible to disease. The liver is mainly responsible for detoxification, blood clotting, immunity, metabolism, and liver juice production, etc. The liver is also the organ with the longest life span in the body – 70 years. This means that under normal conditions, a person’s liver function does not begin to decline until age 70, compared to 25 years for the skin, 35 years for the bones, and 40 years for the teeth and eyes. However, the liver is the only organ that does not feel pain, so even if there is a real problem with the liver, it will probably not notify us (pain), which requires us to: correctly understand the liver warning information, to protect their health in a timely manner. The liver may be “silent”, but it can still behave abnormally! The liver is a silent organ, and when it is overloaded, it causes heat to escape from the body and can easily transfer heat to other parts of the body so that it can try to cool itself by excessive sweating. Tight muscle pains can be liver disease. Vague pains with tight muscle pains, or swelling, are most likely caused by the liver. We should know that chronic hepatitis can cause slight enlargement of the liver, and if it reaches the degree of liver fibrosis and cirrhosis, it will be more powerful, and the surface of the liver will be rough and hard, making people feel muscle tightness. As for conditions such as fatty liver and liver cancer, because they squeeze the surrounding tissues, the muscles will also feel as if they are being held up by something. With a bad liver, corresponding symptoms will appear on the face. Long-term staying up late will lead to different degrees of damage to the internal organs, especially indirectly leading to the accumulation of liver toxins, which leads to blocked hormone secretion in the body, and the liver reduces the increase in sebum secretion, eventually leading to the growth of acne and the appearance of pimples and acne. According to data studies, for patients with liver disease, nephritis, and gastrointestinal diseases can cause bad breath to appear. When the liver is damaged, our mouth emits a putrid and strong odor. For such patients, I recommend maintaining the habit of exercising moderately every day and gradually controlling the amount of exercise according to the different conditions of one’s liver function. In the early stage of exercise, one should jog without affecting the comfort of the body and control the jogging time with fatigue. Liver care is by no means a one-day effort, anything is valuable in persistence.
