Dear friend, welcome to HCM!
do you mean swelling over the body? or the abdomen is distended?
Do you get pain in the flanks, fever, chills, nausea still?
We need specific description of your symptoms in detail to answer your query more precisely.
However, you could have residual/ recurrent cystitis
(UTI) and/ or kidney dysfunction
if there is swelling appearing all over.
H. pylori can cause gastritis
(acidity) and has no connection to UTI.
Take care and please keep me informed of your progress.
I hope to have answered your query satisfactorily.
