Gas and indigetion. To this recurrence?

Having frequent gas and indigestion. Less spicy, less oily and boiled food gives relief. On 14.10.22 did USG and found borderline Hepato splenomegaly. In the last part of 2023 due to a family emergency had some exceptions in my diet and the problem reoccurred. Did a UGI endoscopy on 31.12.2023 and found everything normal. In the Fibroscan report dt.30.12.2023 CAP(db/m) Mean is 263, E(kPa)median is 4.0 and IQR/Med is 11%. Is the fibroscan report normal? What should I do for a permanent solution to this recurrence? I don't have much constipation and in stress sometimes my bowel does not clear regularly. Presently going through a strict diet and my symptoms are relieved at 90%. In 2021 I suffered from COVID-19.
