In recent years, the number of elderly people with abnormal liver function is increasing. The main reason for this is drug-related hepatitis. As people get older, the function of each organ is gradually decaying, and with the increasing number of medical examinations, advanced medical devices can be used to determine each organ, therefore, many elderly people are examined for some organ damage to varying degrees. For example, coronary heart disease, hypertension, hyperlipidemia, diabetes, degenerative joint disease, cerebral infarction, cerebral thrombosis and so on. Some elderly people can be counted as suffering from more than 10 diseases. Theoretically, damage to the organs should of course be treated with drugs to improve and restore their function. However, it should be emphasized that all drugs need to be metabolized and excreted in the liver and kidneys. A large number of drugs entering the body at the same time will inevitably increase the burden on the liver and kidneys, leading to the deterioration of the already declining liver and kidney function, and ultimately, contrary to expectations, causing irreversible damage to the body. This kind of abnormal liver function in the elderly caused by taking a variety of drugs can be called “senile drug hepatitis”. So, how should I choose the medication? First, you should ask an experienced doctor to help you determine how many diseases you have. It is common sense to distinguish between “mild, severe, slow and urgent”, and to use medication in case of severe and urgent illnesses. However, for some degenerative diseases of the elderly, mainly due to the gradual decline of organ function with age, the test results are certainly not consistent with the normal value, but as long as it does not significantly affect the quality of life, and the drug can not cure the disease of the elderly, you can consider temporarily not to take drugs, using other physical therapy methods to relieve symptoms. Secondly, for chronic diseases that require long-term medication, such as hypertension and coronary heart disease, it is best to choose drugs that are simple to use and in small doses, only once a day, only one capsule of slow-release, long-acting preparations. Third, choose a good time to take the medication, the general drug is best to choose to take before or 30 minutes after a meal. Gastric drugs, including gastric mucosa protectors, are best taken before meals, while diuretics are best avoided before bedtime, the increase in urination at night will affect sleep; antihypertensive drugs are appropriate to take in the morning. It is best not to take both western and Chinese medicines at the same time, and taking them separately can reduce the adverse reactions generated by each other. Fourth, avoid taking the wrong medication because of the number of drugs. Find several small pill boxes of different shapes and colors, and store the drugs you need to take every day in separate boxes, one small box at a time, and take them regularly. Avoid taking the wrong medicine. Fifthly, for the so-called health supplements for the elderly, such as royal jelly, cerebral platinum, calcium, multivitamins, lecithin, deep-sea fish oil, etc., it is better not to take them at the same time as regular medications, because these health supplements are non-essential medications and do not need to be taken strictly on time. Finally, it is also important to remind the elderly not to store too many medications for a long period of time, as storage conditions at home are limited to avoid taking spoiled medications. Medications at home also need to be checked regularly for shelf life, and medications that have exceeded their shelf life should not be taken.
