The liver is a very important organ in the human body and is the largest gland in the body, performing more than a hundred tasks every day. The food we eat is digested and absorbed in the gastrointestinal tract, which includes nutrients and toxic substances, almost all of which enter the liver, where they are digested, absorbed, transformed, and detoxified, making the liver considered the largest metabolic organ. In addition, the liver has a strong compensatory capacity, as long as 30% of the liver tissue is working, it can maintain daily life, so the liver is called the “silent organ”. Therefore, we should take care of and protect this “silent organ” which is very important to us, so what can healthy people, hepatitis B virus carriers and liver disease patients do for their liver? First of all, adopt good living habits: try to stay up as late as possible to let the liver get enough rest; eat less greasy food and more fresh vegetables and fruits; quit drinking and smoking; do not abuse drugs and reduce the consumption of raw and cold seafood. Secondly, it is recommended to visit safe medical institutions: for example, some operations such as ear piercing, tattooing, dental repair, etc. and blood contact, otherwise these irregular operations may transmit hepatitis virus and cause infectious liver disease; furthermore, healthy people or liver disease patients who are not infected with hepatitis B virus, get vaccinated against hepatitis B and hepatitis D. In addition, be alert to some signals from the liver: general weakness, easy fatigue, nausea, aversion to oil and grease, loss of appetite, vomiting, discomfort in the liver area, yellow urine and other symptoms, promptly visit the hospital to check the body. For hepatitis B virus carriers, that is, no symptoms, or symptoms are not obvious can not be slack on their liver, to regularly go to the hospital for examination, so that your specialist doctor a comprehensive understanding of your liver situation, so as to determine the treatment plan, otherwise there is a risk of missing a good opportunity for standardized treatment, bringing serious consequences, making liver disease more and more serious, or even the occurrence of liver cancer. Finally, I hope you can have a clearer understanding of and better protect the liver, the most important metabolizing, detoxifying and “silent organ” of the body.
