First of all, please do not get influenced by any over the counter medication
& advertisements which claim to increase height or reduce weight...it may be harmful.
Height of an individual is determined by Genetics, Environmental & Nutritional factors and Hormonal
factors (most important the Growth Hormone
secreted by pituitary gland
An individual stops growing in height after the fusion of the Epiphyses (growth plates) of the long bones, which occurs by the age of 19-22 yrs in males.
So, as you have crossed the above mentioned age group, height cannot be increased any further with medications.
Regarding the problem of overweight
, you need to make certain certain modifications regarding your diet & lifestyle.
Taking a healthy & balanced diet, avoid high calorie & oil rich foods, exercise regularly & avoid stress.
Wishing you Good Health.
Thanks and take care.
