No, IBS may cause symptoms of abdominal cramping, spasms, constipation and/or diarrhea but it would NOT be expected to cause enlarged lymph nodes.
Now you may have enlarged lymph nodes due to one of many possible reasons and the benign explanations are more likely.
You could have had a recent gastroenterititis and this would do it. This is a viral infection (most typically) of the GI tract and typically will cause some diarrhea and abdominal discomfort.
Some general viral infections will cause enlarged lymph nodes throughout the body. Mononucleosis (Epstein Barr virus) is notorious for doing this for example.
There are a number of general infections >>generally viral that may cause enlarged lymph nodes.
Now on the other hand you may have a case of mesenteric adenitis and this would be associated with enlarged lymph nodes and generally causes some abdominal discomfort.
Bacterial infections of the small bowel or large bowel (colonitis) could be the explanation. A CBC (complete blood count ) would help to differentiate what type of process your body was fighting to cause these enlarged nodes.
It's possible that it may have been a borderline call on the part of the radiologist or in other words the nodes may have not been terribly enlarged and may be more or less normal for you...
Of potential concern with enlarged lymph nodes would be lymphoma which is a malignancy. You would be at low risk for this at your age but it is a possible concern and may warrant some follow up testing.
I hope this information is helpful for you.

Thanks Dr. I haven't had any diarrhea, which made my doctor think any type of gastro infection was unlikely. My CBC and bloodwork are normal, as was stool test for parasites, bacteria and occult blood. I've been having this bloating/constipation for 2-3 months. That being the case would some type of cancer, most likely showed up on the CT scan or bloodwork? Now I am freaking out a little, as I don't think it was any type of infection so I keep thinking theres something wrong. I am assuming they weren't too enlarged, my doctor said he should even have told me, once he saw how I over-reacted and said to not even think about it as it was no big deal. But of course, I can't stop thinking about it. Thanks!
Some cancers show up on a structural study while others not so well.
I get the impression from your remarks above that the findings of enlarged lymph nodes was probably not that significant and may have been a borderline call. It may be normal for you for example.
You probably did not have any grossly enlarged nodes or a suspicious group or they would have been standing on their heads....
At age 29 you are at very low risk for cancer.
No I doubt that is the case.
How often do you have a BM?
You can help this conditrion in general by increasing your daily fluid intake and get daily exercise such as walking at least. You may benefit from a daily stool softener if you have hard firm stols. Options here would include Colace, Docusate, Surfak or mineral oil...
You might try a probitotic to see if this helps with the bloating problem. This helps to normalize the GI tract with beneficial type bacteria. Some bacteria are more gas forming and can contribute to the bloating symptom.'
probiotic....DanActive or Activia as examples.
You are very welcome!
