I'll try to give you an informed answer here but it's tricky as context matters. Generally IBS should not interfere with sleep excessively. Sure you might wake up 30min early due to cramps in the morning or you might have to go to the bathroom in the middle of the night after eating a big chilli (or something you don't tolerate well) just before you go to sleep.
Hardly surprising to most patients, but if you have these problems on a regular basis without any specific trigger this might be a red flag. Nighttime symptoms and awakening from your sleep is something Physicians often ask as a standard question to rule out other potential causes and it is cited in several scientific publications as a warning sign or something to pay attention to. (See references below)
"In taking a detailed history, patients should be asked specifically if they are awakened from sleep by the symptoms or if they are already awake when symptoms occur" page 4
As you see it depends a lot on why you are awakened at night. Additionally I know that getting a correct IBD diagnosis takes an average of 5 years after seeking medical care for these symptoms the first time. This was a study made in Sweden, so it's not representative for every healthcare system ofc. Now I'm not saying you might have IBD, you have had your testing done and you'll know the circumstances, but I'm trying to convey that it might be tricky to find a correct diagnosis because of the asymmetry presented due to IBS being a diagnosis of exclusion. Something to keep in mind when considering your nighttime symptoms. Hope this was helpful and hey I can tell you there are several drugs in development treating IBS pain You can checkout the Pipeline I wrote here: https://www.ibsgroup.org/forums/topic/353586-new-treatments-in-development/
Hi- I have exactly what you are talking about, it has been this way for years. Early morning pain and cramps. I have been told by many doctors that that means it may be something other than IBS because IBS apparently should not cause sleep disturbances. However, I have always and only ever been diagnosed with IBS.
When I was super sick I woke up at night many times to do diarrhea and also because I was in pain. So even though it may be a red flag, if all the testing/excluding all diseases(IBD for example) is negative then it can also be a symptom of IBS.
My only symptoms related to sleep are when evening time approaches, around 8-9PM my guts start burning. During my sleep I have no issues, after I am waking up I have horrible back pain though. I need to have a hot shower to relax my back muscles otherwise I can barely move.
