IBS Types: Why Symptoms and Treatment Differ
Many patients come in with a diagnosis of Irritable Bowel Syndrome (IBS), but their symptoms can look very different. Some struggle mostly with constipation and bloating. Others have frequent loose stools and urgency. Some alternate between the two. This is important because IBS is not one single condition with one single treatment. IBS is considered a disorder of gut-brain interaction, meaning that there can be changes in the way the gut moves, senses pressure and communicates with the nervous system. This is also why patients can have significant symptoms even when a colonoscopy, imaging or basic laboratory testing is normal.
Different Patterns of IBS
IBS is generally divided into three main types:
IBS-C is constipation-predominant IBS. Patients may have hard stools, straining, bloating or the feeling that they have not completely emptied their bowels.
Interestingly, having a bowel movement every day does not necessarily mean that you are not constipated. If bowel movements require significant straining or consistently feel incomplete, constipation may still be part of the problem.
IBS-D is diarrhea-predominant IBS. These patients may have loose stools, urgency, frequent morning bowel movements or diarrhea soon after eating.
IBS-M is mixed IBS, where patients alternate between constipation and diarrhea.
Knowing which pattern is present helps us decide where to focus treatment.
Why Can Bloating Be So Uncomfortable?.
Another common feature of IBS is visceral hypersensitivity.
Simply put, the nerves in the digestive tract may become more sensitive to stretching and pressure. A normal amount of gas or intestinal distention may therefore feel much more uncomfortable to someone with IBS.
This also explains why bloating does not always mean that the body is producing an excessive amount of gas.
Sometimes the issue is how the intestinal tract is sensing and responding to it.
There Is No One IBS Treatment
Because IBS can present so differently, treatment should be individualized.
For one patient, improving constipation and intestinal motility may make the biggest difference. For another, identifying food triggers may be more important. Others may need treatment directed toward diarrhea, gut sensitivity, stress or the gut-brain connection.
This is why we don’t like to approach IBS as simply a list of foods to eliminate or supplements to take.
The more useful question is:
What pattern is your digestive system showing, and what may be driving it?
