Abdominal pain, cramping, diarrhea, constipation: Today most doctors recognize these symptoms as possible signs of irritable bowel syndrome (IBS).
But standardized criteria to diagnose this condition didn’t exist until the 1980s. Prior to then, some doctors dismissed IBS as a psychosomatic issue due to the absence of physical evidence related to IBS (e.g., bleeding, growths, obstructions).
With one in six Americans suffering from this disorder, you may find that hard to believe. And that's not the only thing that might surprise you about IBS, says Michael Brown, MD, a gastroenterologist at Rush University Medical Center.
According to Brown, there are a few other common misconceptions about this disorder, so he offers the following facts:
While young and middle-aged women tend to attract more media attention when it comes to IBS, it affects men as well. In fact, one third of those suffering from IBS are men. Doctors also diagnose it in children and older adults.
Diagnosing IBS involves a process of elimination and can take time. But make no mistake, the condition is real and has a set of clearly defined diagnostic criteria that can reduce the need for invasive and expensive testing.
If you experience symptoms that interfere with your daily living, you should definitely discuss it with your primary care physician or a gastroenterologist. To diagnose the condition, doctors will refer to the Rome criteria, [see below] which specifies the types and duration of symptoms that define IBS and its subtypes.
Bloating is a common but not uniform feature of IBS
While stress can trigger and even worsen symptoms — perhaps because of disruption in communication between the gut and the brain — it isn't what causes IBS.
Actually, no one knows for sure what causes IBS, but the nerves and muscles surrounding bowels appear to be super sensitive in people with IBS, which can cause sensitivity to only mild bowel irritation and gut movement abnormalities that result in constipation, pain and diarrhea.
While doctors define these two conditions as diseases, they categorize IBS as a syndrome. Why?
Like stress, some foods spark IBS symptoms, and even the simple act of eating can sometimes bring about symptoms. While food affects everyone differently, for those with IBS, certain culinary culprits appear to be especially problematic, including the following:
Brown recommends keeping a food and symptom diary to help identify problematic foods. But changing your diet is typically not enough to curb symptoms. Managing stress and anxiety can also play an important role in alleviating symptoms, as can medications for more severe cases.
Some patients may also benefit from physical therapy which can help tighten (or loosen) the pelvic floor and abdominal muscles, areas that may contribute to IBS symptoms.
