Indigestion. What more can be done?

From the past 2 months i am facing indigestion. No medicines worked for me in the first month. I has acidity, bloating ,gas and constipation(but stool was soft. I was just not able to pass it properly).This happened every single day . In the second month I switched to naturopathy treatment which cured my acidity and did improve my digestion a bit but not completely. I still have occasional(2times a week) bloating, gassy stool which disintegrates and belching. This increases a lot during my period(extra body heat, lose motions). I am unable to digest milk and related milk products which i could digest earlier very easily. I am 152cm and currently weigh 50.5kg(i have lost 3kg in 2 months) Can this problem be cured? How long will it take for my digestion to improve? What more can be done?
