I’d be surprised if a J-pouch could suck in much air, but a well-trained rectum can (see https://en.wikipedia.org/wiki/Le_Pétomane for some amusing history). My guess with this much gas would be SIBO, which is usually treated with a longish course of rifaximin or doxycycline.

I would also blame it on a kind of bacterial overgrowth. Sometimes I was going to bed at night and could pass gas every some minutes. A bathroom trip could resolve that. Otherwise it would not stop until bacteria had finished their 'meal'. That's why I don't eat about 5 or 6 hours before sleep.

It should be a lot better when you take antibiotics(?)

It can also help to cut down sugar, not to overeat and to have a cup of herbal tea with a meal.

Instead of butt in the air you could try to lie flat on your front.  Bend your knees (feet in the air) and lean your legs left then right (slowly). Occaisonally lower your legs to the floor (relaxing moves things along too)

As well as manipulating the pouch with your muscles, the act of pressing against the floor helps massage the area too.  You can even try sliding a hand under a particuarl part of your stomach to apply a bit more pressure.

I find i get much more out and in a totally controlled way.

You need more space of course, but as its safer i find i can do it in any quet room fully clothed (kitchen floor, on a bed even on a setee although theres less room).

I have had a j pouch for approx 39 years-I had some problems with pouchitis, etc-a few years ago I went to Cleveland Clinic and saw Dr Bo Shen-who has since left there and went to NYC-I had a variety of testing done and it was shown that my pouch was stretched out and I was prescribed pelvic floor therapy and to stop taking NSAIDS for joint pain-Dr Shen felt like the NSAIDS damaged my pouch.The pelvic floor therapy was helpful-o still use it today.I have been having large amounts of gas that causes me to experience abdominal discomfort and nausea. I do not know why I started to have so much gas-after I eat anything I have abdominal distention and need to use the bathroom to expel the gas. I have also found the need to change position to expel the gas-after reading other peoples experiences I realized I am not alone in this. I am now living near Huntsville Alabama and there are no specialists that deal with J pouch problems here-I am now thinking of trying a probiotic to see if that helps decrease the gas. If anyone has any other suggestions I would love to hear from you.

@EAC When gas is the major symptom then it’s worth suspecting SIBO. A longish course of antibiotics (doxycycline or rifaximin) seems to be commonly used to treat it - doxycycline for a couple of months worked for me. There is a breath test for SIBO, but my doctor went by symptoms alone.

Thank you for your reply-I will look into this
