Whether or not you can still grow taller at the age of 20 is determined by the development of the body’s epiphyses. If the epiphyses have not closed, there is still a possibility of growth; if they have already closed, they will not continue to grow. In most cases, the growth of height depends on the development of the epiphyses. If the epiphyses have not closed after the age of 20, there is still a possibility to grow taller. If the epiphyses are closed, there is no possibility of further growth. Generally, the epiphysis of a normal person closes around the age of 18. Of course, in addition to epiphyseal development, the body’s nutritional intake and lifestyle also have a great deal to do with height. When the epiphyses are not completely closed, you can eat more nutritious food and choose sports suitable for your situation, which can also promote the growth of height. Therefore, in order to continue to grow taller at the age of 20, it is best to go to the hospital to check the epiphyseal development, under the guidance of a professional doctor to regulate.
