IBS (Irritable Bowel Syndrome) is a common digestive disorder that affects the large intestine. It causes a variety of uncomfortable symptoms but does not damage the digestive tract. IBS is a long-term condition that can come and go over time.

Common Signs and Symptoms of IBS

1. Abdominal Pain or Cramping
Often in the lower belly
Relieved after passing gas or having a bowel movement

2. Changes in Bowel Habits
Diarrhea (IBS-D) – frequent, loose stools
Constipation (IBS-C) – hard or infrequent stools
Mixed type (IBS-M) – alternating between diarrhea and constipation

3. Bloating and Gas
Feeling full or swollen in the abdomen
Excessive passing of gas

4. Mucus in Stool
White or clear mucus may appear in the stool

5. Feeling of Incomplete Bowel Movement
Even after going to the bathroom, you may feel like you haven’t fully emptied

Additional Clues
Symptoms often worsen after eating
Symptoms may be triggered by stress or anxiety
No blood in stool or fever (if these are present, it could indicate a different condition)

How IBS Is Diagnosed
There’s no single test for IBS. Diagnosis is usually based on:
Review of your symptoms
Physical exam and medical history
Excluding other conditions (like celiac disease, IBD, or infections)
Doctors may order blood tests, stool tests, or a colonoscopy if needed
