I am 16 and my height is only 4 feet and 10 inches and my weight is 52kg, i am really not happy with my height and weight and also my period irregular?

See MD: Your body mass index is just a little elevated, so a healthy diet and exercise would fix that. As far as your height goes, if you've had your period for more than 3 years, your growth plates are probably closed so you don't have much growth potential left. You should discuss your growth and irregular periods with you physician.

Normal: height is genetic with some environmental influences, after periods height increase is almost complete. Adolescent girls usually have irregular periods. This may be normal for you

Unhappy: Your height and weight are genetically determinedAs it stands your BMI is normal. It would seem that you have reached at least 90 percent of your height and as a 16 year old it may take several months before your body adjusts to a normal monthly schedule
