Low Stomach Acid Help?

For about 7 months now I think that I may have had low stomach acid as a result of taking a two week dosage of Zantac 150. I am a 17 year old male going through puberty and I am stressed because I am concerned that the low stomach acid has affected my growth/puberty. Is it possible for low stomach acid to have an effect on growth or development because of the inability to digest proteins? Could it have decreased my testosterone levels or raised my estrogen levels? I need as much info as possible on the concern of whether this could have had any type of effect on growth/development/puberty. I have not been formally diagnosed by a gastroenterologist on have low stomach acid, but I am going to one tomorrow. It seems that I have had a lot of the symptoms of low stomach acid, and it seemed that the Betaine Hydrochloride Capsules have helped. All information is appreciated thank you!
