I can understand your frustration. You mention that you have had
abdominal surgeries including gallbladder
and also mesh insertin
. Your symptoms of pain and fullness in the upper part
of the abdomen may indicate slow passage from the stomach
into the intestine of your ingested food. This could happen in
different circumstances. If you have some scarring at the lower
end of the stomach opening from an old healed ulcer , that could
cause mild blockage. If you are a diabetic and not well controlled
you can have a condition called Gastroparesis
that would slow down
the stomach. But my best guess in your case, is "Adhesions".
Especially after multiple abdominal surgeries , scar tissue develops
and in some, this can cause kinking of the intestine and cause intermittent
blockage or obstruction. If you get relief after passage of gas or after
, this could be a cause. It is very difficult to identify adhesions
but some cases a GI series and a small bowel follow through X-rays
can show abnormalities, if there is significant kinking.
In some cases mesh itself can cause reaction and scarring with pain.
Hope you have had complete blood work.
You can discuss these with your doctor and get tested .
I wish you well.
