Hello dear
I understand your concern
Sorry to say there is no medicine that will increase the height at your age.
Height is determined by a combination of genetic and environmental factors. Human growth is regulated by human
growth hormone secreted by
anterior pituitary gland, which gradually subside after adolescence.
At the age of 18-19 year and of long bones/
epiphyseal plate has already been closed so no further increase in height.
Some Orthopedic Surgeons claim to increase length of long bones, thus height by applying traction or by ilizarov technique.
So if your very concern then consult the orthopedics surgeon for the surgical process.
Eat healthy diet rich in protein, drink plenty of water and maintain proper posture, do regular exercise.
Just accept your height and try to feel comfortable with it.
Avoid commercial product available in market
Hope this may help you
Contact further if follow up needed
Best regards
Dr. Sagar
