Dear Priya, Height of an individual is determined by Genetics, Environmental & Nutritional factors and Hormonal factors (most important the Growth Hormone secreted by pituitary gland in brain) An individual stops growing in height after the fusion of the Epiphyses (growth plates) of the long bones, which occurs by the age of 15-19 yrs in females. So...you may still have a chance of gaining your height. Make sure that you are taking a healthy & balanced diet, exercise regularly & avoid stress. Protein rich diet like soya, groundnut, pulses, etc should be incorporated in your diet plan. One more thing...avoid consuming any over the counter medication which claim to boost your growth hormone & increase height...it may be harmful. Wishing you Good Health. Thanks and take care.
