IBS symptoms (irritable bowel syndrome) centre on recurring abdominal pain or cramps linked to bowel movements, together with bloating and a change in stool frequency or form: diarrhoea, constipation or both. The pain often eases after passing stool. IBS is very common, affecting roughly 1 in 10 adults, and does not damage the bowel or cause cancer. Symptoms such as bleeding, weight loss or night-time diarrhoea are not typical of IBS and need investigation.
Key points
- Main symptoms: abdominal pain with bowel changes, bloating, urgency, mucus and incomplete emptying.
- Types: IBS-D (diarrhoea), IBS-C (constipation), IBS-M (mixed).
- Stress, certain foods, meals and hormonal changes commonly trigger flares.
- Diagnosis is based on symptoms after simple tests exclude other conditions.

Main IBS Symptoms
- Abdominal pain or cramps, often lower abdomen, related to bowel movements
- Bloating and a visibly swollen belly, worse as the day goes on
- Diarrhoea, often urgent, especially in the morning or after meals
- Constipation with hard or lumpy stools
- Alternating diarrhoea and constipation
- Mucus (white or clear) in the stool
- Feeling of incomplete emptying after passing stool
- Excess gas and rumbling
Doctors diagnose IBS when pain occurs at least one day a week over the last three months, linked to defecation or to a change in stool frequency or form (the Rome IV criteria).
Types of IBS
| Type | Main stool pattern |
|---|---|
| IBS-D | Loose or watery stools most of the time |
| IBS-C | Hard or lumpy stools most of the time |
| IBS-M | Both hard and loose stools |
| IBS-U | Does not fit clearly into one pattern |
Your type can change over time, and treatment is tailored to it.
What Does an IBS Flare Feel Like?
A flare often begins after a large or fatty meal, a stressful day or certain foods. People describe crampy pain, rapid bloating, urgent trips to the toilet or, in IBS-C, days without a bowel movement and a heavy, swollen feeling. Flares can last hours to days and then settle.
Symptoms Outside the Gut
- Tiredness and poor sleep
- Back pain and headaches
- Nausea and early fullness (overlap with functional dyspepsia)
- Frequent urination
- Anxiety and low mood, which both trigger and result from IBS
IBS in Women
IBS is more common in women, and symptoms often worsen around periods. Painful periods, endometriosis and pelvic floor problems can mimic or coexist with IBS. New bowel symptoms in women over 50, especially with bloating and early fullness, should be checked for ovarian causes.
Common IBS Triggers
- Foods: onion, garlic, beans and chana, cabbage, milk (in lactose intolerance), wheat in some people, fried and spicy food, artificial sweeteners
- Drinks: tea and coffee in excess, fizzy drinks, alcohol
- Large or irregular meals
- Stress and anxiety through the gut-brain connection
- After gastroenteritis (“post-infectious IBS”)
- Hormonal changes
- Some antibiotics and changes in gut bacteria
Red Flags: When It May Not Be IBS
See a gastroenterologist promptly if you have:
- Blood in the stool or black stools
- Unexplained weight loss or anaemia
- Diarrhoea that wakes you at night
- Fever or persistent vomiting
- Symptoms starting after age 45–50
- Family history of colon cancer, inflammatory bowel disease or celiac disease
These may point to IBD, celiac disease, infection or colon cancer, and a colonoscopy may be needed.
How IBS Is Diagnosed
- Detailed history and examination
- Blood count, inflammation markers and celiac screening
- Stool tests (infection, calprotectin to separate IBS from IBD)
- Thyroid tests where relevant
- Colonoscopy only when red flags or age-related risk are present
Treatment Options
- Diet: regular meals, adequate water, adjusting fibre (soluble fibre like isabgol helps many), and a supervised low-FODMAP approach for persistent symptoms
- Medicines by type: antispasmodics for cramps; loperamide or other agents for IBS-D; osmotic laxatives for IBS-C; low-dose gut-nerve modulators for pain
- Stress management: exercise, sleep, breathing techniques and, where needed, gut-directed psychological therapy
- Probiotics may help some people
