* Food. Old people can eat some foods rich in high-quality protein, such as milk, eggs, fish and so on. These foods can provide necessary nutrition for the body and enhance physical fitness. At the same time, moderate consumption of red dates and longan, two foods with the functions of invigorating qi and enriching blood, is also beneficial to health.
* Drugs. According to the theory of traditional Chinese medicine, the general weakness of the elderly may be caused by deficiency of both qi and blood. Therefore, under the guidance of doctors, drugs such as Bazhen Granules and Shiquan Dabu Pills can be used for treatment. However, it should be noted that the elderly should follow the doctor's advice and should not increase or decrease the drug dosage by themselves.
The above suggestions are for reference only. If the old man is seriously weak or lasts for a long time, it is recommended to seek medical treatment in time.
