HI
Sir , my mother's age is 65 yrs old,with eskamic heart, her angiogram report is normal no blockage has been found. Now she is having monotrate 10mg,dytor 10 after b.f,Deplatt A (75) after lunch and Rosuvas (10) and Cardace (5) after dinner. Now for few weeks before she is suffering from severe stomach pain and severe acidity with consitipation. We consult a Gastroenterologist he prescribed drotin for pain(sos), and pan 40,and suggested for lfg test. In the test report her billirubin os 1.12,sgpt307,gopt800. He then again suggested for MRCP test. They are suspecting stone in bile duct and gall ballder. Dr also prescribed URSOKEM Plus twice daily. My question is that is it safe for person for gall stone operation like her, or some medicine are there so she can be cured without operation
