I am a 34 year old female.in 2018 i underwent an endoscopy which was normal, i had bloating and digestion issues that's why i underwent, but again at times i do have the same issue of bloating, digestion issues, soemtimes acidity and change in bowel like stomach upset. My life is stressfull that's true but don't know wether out of stress or physcial problem. Do i need to udnergo endoscopy again? Or there is amy alternativw to endoscopy like blood test or usg or xrays which i can do to check my digestion and eseophasgylus functions and other gastric issues. Plz suggest, as endoscopy everytime is a bit painful. Thanks!
