The liver is a complex and mysterious organ, like a chemical factory that synthesizes various raw materials into substances needed by the body, and like a waste treatment plant that turns harmful substances that enter the body or are produced by metabolism in the body into harmless substances. However, do not pay attention to protect and cherish it, it will lead to disease, and even life-threatening. What happened to Fu Biao, a famous actor, undoubtedly made people know more about liver cancer, which is known as the “king of cancer”. But liver cancer is only one of the big family of liver diseases, there are also fatty liver, alcoholic liver, drug liver, hepatitis B, liver cirrhosis and other liver diseases, so how important it is to do a good job of liver health care, away from liver disease! The liver, like the heart, is one of the important pillars that support the building of life, because it has physiological functions that are inseparable from life. One is the metabolic function. We eat a lot of food every day, the proteins, fats, sugars and vitamins in the food, must first go to the liver for chemical processing, into the nutrients that the body needs, and then for life activities required. The second is the detoxification function. Toxic waste generated during the metabolic process of the body, plus toxins mixed into the water and food, must be detoxified by the liver. The liver is the body’s largest detoxification organ, as long as the liver function is normal, there is no need to worry about residual toxins in the body or poisoning. Third, the immune function. It safeguards health by engulfing, isolating and eliminating invading and endogenous pathogens. In addition, there are physiological roles such as bile production, synthesis of clotting factors and regulation of water and salt metabolism. In short, life cannot be lived without the liver, and a healthy liver is a healthy life. Although the liver is powerful, it has its limits. As we reach middle age, our body enters an eventful period and the liver cells tend to weaken. However, the number of harmful substances that the liver is exposed to is increasing, such as pesticide pollution, tobacco and alcohol addiction, taking various drugs and additives in the diet, etc., are increasing the liver’s detoxification burden, and once the load of liver function is exceeded, the liver itself will be poisoned. Such as chronic alcoholism, chronic drug poisoning, etc., and some even develop cirrhosis of the liver. The liver is also a fragile organ that can cause disease if not properly protected. The most vicious of the liver’s natural enemies is the hepatitis virus. Among them, hepatitis B virus is the most prominent, and it is the main cause of liver cancer. Every year, about 300,000 to 500,000 people die from hepatitis B-related liver disease in China. More middle-aged people suffer from liver disease, and most of the disease is hidden and difficult to detect early, which has become a major threat to middle-aged people. The scary thing about liver disease is that there are no particularly significant symptoms at the beginning of the disease. The liver has no nerves, so minor problems do not manifest themselves earlier, so the liver is called the “silent organ”. Once you feel pain in the liver, it is because the liver is enlarged and the liver envelope is involved. In addition, the liver has a strong compensatory function, and when it is damaged, it can still maintain daily life as long as about 30% of its function is still functioning, so the liver is also known as a “tenacious organ”. Because of the liver’s “silent” and “tenacious” character, most liver diseases are asymptomatic, which is why doctors call liver disease the “biggest invisible killer”. Although liver disease is scary, it is not fatal as long as it is detected in time. Therefore, middle-aged people should pay special attention to protecting their liver, and if there is any discomfort in the liver or liver area, it should be checked early and liver disease should be treated early. So how to give the liver to reduce the burden at ordinary times? One, is in a relaxed mood, optimistic and cheerful: Chinese medicine cloud: worry hurt the spleen, anger hurt the liver. Liver like Shu evil depression, when angry, easy to cause liver gas stagnation, liver gas is not comfortable, and over time prone to liver disease. Middle-aged people shoulder the work and family two burdens, emotional instability, often love to anger or sulking, which is extremely detrimental to the liver. Therefore, you must learn to self-regulate, and try to be calm, relaxed, optimistic and cheerful. Second, is to quit smoking and alcohol, to protect the liver: smoke contains more than 300 kinds of toxic substances, these toxic substances, not only damage the lungs, heart, brain and other organs, but also damage the liver. Alcohol is second only to tobacco life killer, long-term heavy drinking can cause alcoholic hepatitis, followed by liver necrosis or liver cirrhosis. Therefore, people should quit smoking and alcohol in middle age. Third, is a balanced diet, regular ration: eat too much, more than the body’s needs, the excess will accumulate in the human body caused by obesity. But the activity is reduced, the excess nutrients into fat will also be fat. Obesity is not only the cause of cardiovascular disease, and can lead to fatty liver, fatty liver further development can cause liver cirrhosis. So middle-aged people a to eat in moderation, nutritional balance. Fourth, is regular drinking water, favorable metabolism: middle-aged and elderly people with the increase in age, the body gradually reduce water, but due to the decline of the thirst center, the body is often not feel thirsty, so it is extremely important to drink water regularly. Hydration can maintain the effective amount of circulating blood in the body to ensure the liver blood supply, so that its metabolism is carried out smoothly; hydration can also reduce the concentration of its metabolites, reduce the damage of toxic substances to the liver, to play the role of “internal washing”. Hydration to plain water is good, do not believe in the market of a variety of drinks, to prevent damage to the liver. Five, is the prevention of liver disease, early treatment of disease: once the bloating, loss of appetite, nausea, jaundice, liver or liver discomfort, etc., should promptly go to the hospital for treatment. The principle of treatment is to use less medication and more rest. Too much medication, too long, is not only a waste and will increase the burden on the liver, causing adverse drug reactions, and even cause drug accumulation poisoning. Sixth, is to exercise, persistent: frequent outdoor physical activity is a liver, the best way to protect the liver. Exercise can not only promote the body’s gas exchange, blood flow, so that the liver has enough oxygen and nutrients supply, and can accelerate metabolism, promote the elimination of waste or toxic substances out of the body, to play a role in liver health, liver protection. In addition to this, physical examination is more important, because “the disease from the shallow Chinese medicine”, early detection of the body’s improper and receive appropriate treatment, is the wise move.
