Hello,
To gain height, focus on maintaining a healthy lifestyle with a balanced diet, regular exercise, and sufficient sleep. While these factors primarily influence height during growth years, there are limited options for height increase in adulthood. Limb lengthening surgery is an option for some individuals seeking height enhancement. Still, it's essential to consult with a qualified orthopaedic specialist to discuss the risks, benefits, and suitability of this procedure for your specific case.
