Does IBS make your burps smell?

Sometimes when I burp I can literally smell it, as can other people.
I try closing my mouth to burp but the force of the burp causes my to involuntarily open my mouth and a foul smell follows.
My burps always have a foul taste too, of everything I have eaten all mixed together. It can be pretty gross.

Could someone else share your experiences so that I know I'm not alone?

  1. Hi , I'm sorry that you're experiencing this.
    One of our contributors talked about a similar symptom along with constipation: "I started having one of the most uncomfortable parts of constipation: hard, disgusting burps." (https://irritablebowelsyndrome.net/living/constipation-vacation), as well as this community member who shared in this forum: https://irritablebowelsyndrome.net/forums/belching-and-gas. The comments here might also be helpful.
    I'm also going to link this article about excessive gas and possible causes: https://irritablebowelsyndrome.net/symptoms/gas-flatulence-common-sign-symptom-of-ibs, maybe you'll find some helpful ideas in there.
    Have you asked your doctor about this and if yes, what did they say?
    Have you ever been tested for SIBO (https://irritablebowelsyndrome.net/living/getting-tested-for-sibo), as this could be a potential cause?
    Hopefully, other community members will chime in soon and share their experiences with you. Karina (team member)

    1. I don't get constipation, usually the opposite. I suffer with a lot of wind more.

      1. Also sometimes I uncontrollably belch loudly half way through a meal, which can be gross. Yesterday I hiccuped loudly and went to say "excuse me" but instead a massive burp followed, sounding gross and bringing back food I'd just swallowed back into my mouth.
        I put my hand over my mouth then said "pardon me" very apologetically because others were eating. They didn't mind but that's not the point.


        I ate slower after that but still managed a big burp afterwards, although not as wet. I couldn't smell it though.

        1. Since gas seems to be a big problem for you, I would definitely consider getting tested for SIBO if you haven't already.
          I'm also wondering if this might be caused by something you eat? I get horrible bloating from gluten, for example. Others have a similar reaction to dairy, or even other foods.
          Do you get these symptoms at any time of day, or at specific times?
          Have you ever tried keeping a food diary (https://irritablebowelsyndrome.net/living/food-journal-download) to see if you can find a common trigger ?

      2. Hi ! My stomach rumbles loudly as soon as waste starts making its way through my small and large intestine. I can feel nauseous during this time too. Worst case is belching and farting at the same time, with and without foul smells and tastes. I have a simple rule of thumb: Let it rip, even if it causes embarrassment! And always cover my mouth just in case. I did try drinking 9.5+pH water to quiet the rumblings, and I thought it worked at first. But then the rumblings started up WHILE I'd been drinking an entire bottle of this alkaline water! So--back to the drawing board.
