Iam 17 years boy iam 175 cm tall iam not growing height since 1year my younger brother is taller than me ineed to grow 185cm please help me , iam very serious about this?

Growth last year?: If there was growth last year, may still grow some this year (must check the doctor's growth chart to know). Most people reach their maximum height in their late teens. Without nutritional problems or chronic childhood illnesses, height is largely based on genetics and parental heights. Aside from eating right, exercising, sleeping well, and being happy, there's little one can do to change height.
