Thank you for getting in touch with us. As I see, you are complaining of a loss in height after your started weight training
. Loss in height is not possible in normal condition unless there is a traumatic injury
to a part of the body or arthritis
which deforms the knee. The only reason I can think of is that you have put on some muscle mass and have become more bulky in the last one year. Well built men often look shorter than thin man. If you still feel you have lost height, you can get in touch with an Endocrinologist
or Internal Medicine specialist and he can guide you further. Hope this helps.
