First, steel needle disinfection is not strict.
The main instruments of "catgut embedding at acupoint to lose weight" are steel needle and catgut. These two instruments have been regarded as disposable products abroad, and regular hospitals in China also advocate patients to use disposable needles. Although it is not mandatory, at least one injection should be given to everyone, and it must be disinfected with professional high-pressure steam after use, which is difficult for informal hospitals to do. In hospitals, steel needles are generally disinfected with alcohol, but alcohol can only kill bacteria and has no effect on viruses such as hepatitis B and hepatitis C. Especially in summer, the concentration of alcohol after volatilization may not reach 75%, and the disinfection effect will be worse. After steel needles are inserted into human acupoints, capillaries may be broken. Therefore, if the steel needle is reused without adequate high temperature and high pressure disinfection, it is easy to cause the spread of blood diseases between people, and the most contagious ones are hepatitis B and AIDS.
Second, there is a problem with needle users.
If you don't have professional training and are not familiar with the acupuncture points or anatomical structures of the human body, you are prone to danger. "Catgut embedding at acupoints to lose weight" is actually an extension of acupuncture weight loss, and it is a medical method that invades the human body. Although the needle was not applied to the fatal key part, the needle collector was prone to faint when he was hungry, weak and tired.
Third, the direction of embedding thread is not well grasped, and depression or nerve injury may occur.
"Catgut embedding at acupoint to lose weight" requires that half catgut be implanted into fat layer and half into muscle. If it is improper, simply implanting the thread in the fat layer will cause fat liquefaction and bury some depressions. If you stab the wrong point, it will seriously damage the nerves of the human body.
