The epiphysis of normal people began to close at the latest 18 years old. From then on, they no longer have the ability to develop, so they are not tall. You're 22 years old, and you can't grow up whether you take medicine or exercise.

If you really want to increase your height, you can go to the hospital for an operation called Iriza Love (especially Baidu Summer), which is mostly used for deformity correction and limb lengthening.

Its principle is: cut off the tibia and fibula (that is, the two bones of the calf), install the Iriza love ring frame, and rotate the screws on the frame to make it elongate. The extension speed shall not exceed 1 mm/day. Theoretically, it can be extended indefinitely.

At present, the operation technique is mature and accurate, but all operations have certain risks, and it is generally not recommended unless it is particularly necessary. If you really want to do it, Russian is the first choice for this operation, and its Iriza Love Research Center is the birthplace and authority of this technology. If you want to be in China, the best doctors are Qin Sihe and Xia Hetao.
