Does bloating from eating too much gassy food cause pouch to stretch over time?

No it does NOT i asked that same question to my PCP and she said and i quote no it does its the result to of

drinking to much fluid and it sits in your stomach waiting to pee the excess fluid(s) in your case to much to drink.?

It won’t stretch your tummy but it’s causes discomfort & fills up your tummy with gas so you then struggle to eat the food you need. The fermenting foods that produce the gas can limit your ability to absorb essential nutrients too. So probably something to avoid where possible post surgery. Remember to eat small bites slowly & avoid if possible the foods that cause you the most bloating.
