Gastro prob. Is still there. pls hlp?

I am writing for my mother. She is 60 years. She had her gall bladder with stone rwmoved in 2000. She has hypothyroidism and blood pressure , blood sugar and takes medicine for that . She also has an ear condition, trinititus and also takes medicines bilovas for that. Presently from the month of April all family members except had severe corona. But from that time she is suffering from a strange condition of excessive gas , nausea, loss of apetite and less sleep and improper bowel movement. She had been undergoing medication since then but her condition has not improved. The first doc gave her creon 10000, Sompraz L, she tried it for 6 months but on having med she is alright when she stops it again condition returns. So we showed another doc he asked to immediately  stop  sompraz L and said it was bad for prolactin. He gave endoscopy which was also fine. But on his med also same thing happened. Now we have shown another doc who gave  Colospa, Razd but same thing is still there. Pls hlp
