Irritable bowel syndrome affects between 25 and 45 million Americans. That’s around 10-15% of population. About 2 in 3 people with IBS are female.
What is irritable bowel syndrome (IBS)?
Irritable bowel syndrome (IBS) is a chronic digestive disorder that affects millions of Americans. Symptoms include bloating, stomach pain, diarrhea, constipation and a feeling of incomplete bowel movement. The symptoms might fluctuate with time, but they are frequently lifelong. IBS can be managed effectively with the right approach and treatment plan.
IBS vs IBD
Irritable bowel syndrome or inflammatory bowel disease
IBS and IBD are both gastrointestinal disorders that cause similar symptoms. But they differ in the underlying causes and treatment options.
IBS is made up of a group of symptoms whereas IBD is an autoimmune disease caused by persistent inflammation and swelling of the intestines. IBS does not develop into IBD or cause permanent damage to your intestines such as bleeding or cancer.
Inflammatory Bowel Disease, or IBD, is a chronic condition caused by inflammation of the digestive system. IBD usually manifests in one of three different ways:
- Crohn’s disease
- Ulcerative colitis
- Indeterminate (containing features of both diseases)
What causes IBS?
Although the exact cause for IBS is not fully understood, it is believed to be an interplay of multiple factors:
Dysmobility refers to a condition in which there are abnormal muscle contractions in your gastrointestinal tract
- Stronger and longer contractions may cause gas, bloading, and diarrhea
- Weak contractions may hinder the passage of food and result in dry, firm stools.
- Brain-gut dysfunction
Failure to communicate between the nerves in your brain and gut
- If brain and gut signals are not synchronized, your body may overreacto to normal changes in the digestion process and cause pain, diarrhea, or constipation.
- Hypersensitive GIT nerves
The nerves that control the muscles in the digestive tract can become hypersensitive in people with IBS and cause abdominal discomfort and bloating.
- Childhood trauma
IBS symptoms are more common in those who have experienced stressful situations, particularly in their early years. Research suggests childhood traumatic experiences are associated with an increased risk of developing adult IBS symptoms.
- Gut microbial changes
Changes in bacteria, fungi, and viruses are a few examples. These organisms often live in your intestines and are important for maintaining health.
According to research, IBS patients' microorganisms may be different from those of healthy individuals.
- Severe infection
After a severe case of diarrhea brought on by bacteria or a virus, irritable bowel syndrome (IBS) may appear, also referred to as gastroenteritis.
There may be a connection between irritable bowel syndrome (IBS) and an overabundance of bacteria in the intestines or bacterial overgrowth.

Wheat, dairy products, citrus fruits, beans, cabbage, milk, and fizzy beverages are a few of them.
During times of high stress, the majority of individuals with IBS notice severe or more frequent symptoms. Although stress does not cause IBS it just makes them worse.
Irritable bowel syndrome (IBS) may be your gut's reaction to stress in life, according to some studies.
