Is it possible for me to increase height at 18?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am 18 years old, and my height is 5 feet 8 inches. I want to increase my height to 6 feet.

What should I do?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

It is essential to understand that most people have already completed the majority of their height growth by this time, as the growth plates in the bones typically close between 16 and 18 years in girls and 18 and 21 years in boys.

If your growth plates are still open, a small amount of natural height increase may be possible. To support your maximum potential height,

  1. Focus on a balanced diet rich in protein, calcium, vitamin D, zinc, and other essential nutrients.

  2. Get seven to nine hours of good-quality sleep each night, as growth hormone is released during deep sleep.

  3. Maintain regular physical activity, such as stretching exercises, yoga, swimming, skipping, and workouts that improve posture.

  4. Avoid smoking, alcohol, and excessive junk food, as these can negatively affect bone health.

Maintaining a healthy weight is also essential because being underweight or overweight can impact posture and overall growth.

If you are very concerned, you can consult an orthopedic doctor or endocrinologist for an X-ray of the wrist to check bone age and growth plate status. No medication or supplement can safely guarantee an increase in height after growth plates close.

Focus on good posture, fitness, and confidence, as these can make you appear taller and healthier even if your height does not change significantly.

I hope I have answered your question.

Let me know if I can assist you further.

Thank you.
