Stomach discomfort after two c section.

Hi,i had two c section.After my first c section ,I am completely normal like before pregnancy. But after my second c section, i am not feeling normal. There are some discomfort in my digestive track. Not feeling good about my stomach and digestive track. Sometimes feeling dull ache in lower stomach around my c section scar and sometimes feeling pain when passing gas. Not able to gain weight even with good diet after second c section. Very often feeling tired after going to toilet. I had my first c section on 2017 August and second was in 2021 May. I am doubting about my food absorption and kindly clarify whether surgeries might weakened the digestive/stomach part. Sometimes feeling like always want to go to toilet. After my second c section , scar got infected little bit and it discharged some clear white kind of paste and blood. Doctor said there was some thread irritation and cholesterol is getting dissolved and coming out.Kindly suggest on my stomach discomfort part. Ragards,Ramya
