, Concept Process: Irritable Bowel Syndrome
Irritable Bowel Syndrome (IBS) is a “gastrointestinal disorder with manifestations of
abdominal pain/discomfort and changes in normal bowel habits (Hubert and VanMeter, 2017)”.
The pathophysiology is “the rapid transit time of feces through the bowel. This causes
hypersensitivity on the enteric system (Hubert and VanMeter, 2017)”. The basic concept of IBS
is gastric motility, “which refers to the movement of food from the mouth through the pharynx
(throat), esophagus, stomach, small and large intestines and out of the body (UC San Diego
Health, n.d)”. The small intestine is “approximately 20 feet long, which makes it the longest part
of the digestive system. Here, most of the nutrients and minerals from food are absorbed into the
body (UC San Diego Health, n.d)”. The large intestine, “also known as the colon, is responsible
for absorbing water from undigested food. Food is transported through the large intestine to the
rectum, where it is expelled from the body (UC San Diego Health, n.d)”. A gastrointestinal (GI)
motility disorder can cause feelings of severe constipation, recurrent vomiting, bloating,
diarrhea, nausea, and weight loss (UC San Diego Health, n.d)”. IBS is a GI motility disorder.
Health promotion and disease prevention include “eating more fiber, avoid gluten, and
follow a special diet called FODMAP (Chang, 2017)”. The risk factors for IBS include “Certain
medications, family history of digestive diseases, stress, anxiety, certain foods (Chang, 2017)”.
Expected findings in IBS include “bloating, gas, alternating diarrhea and constipation, lower
abdominal pain, diarrhea, constipation, nausea, fecal urgency and incomplete evacuation of
bowels (Hubert and VanMeter, 2017)”. Laboratory tests that can be done include “stool samples,
blood test, hydrogen breath test, upper GI endoscopy, colonoscopy (Chang, 2017)”. For IBS, the
