Symptoms: Short height

Doctor: Welcome to Ask The Doctor.We are here to help you.Height is constitutional and depends on height of your parents. Short stature can be due to some medical issues too. Height increases till a age, then it stops increasing as the end of long bones fuse by this time.If you don’t have any medical problems, I would not suggest you any medicine for that. Some people try hormones, but trust me interfering with hormones of your body can be serious.Since you have no problems, you can just get your thyroid profile done.Stay away from Newspaper & TV advertisements claiming to increase your height.Share my opinion with your doctor before acting upon it.I hope it helps.Stay Healthy.
