Symptoms worth assessing
Inflammatory bowel disease is easy to mistake for a sensitive gut. These symptoms deserve objective testing rather than reassurance alone:
- Diarrhoea lasting more than a few weeks
- Blood or mucus in the stool
- Abdominal pain, cramping and urgency
- Waking at night to open your bowels
- Unintended weight loss or persistent fatigue
- Iron deficiency anaemia
- A family history of Crohn's disease or ulcerative colitis
How your assessment works
Your appointment begins with a detailed history and examination, followed by blood tests and a stool calprotectin test that measures inflammation in the bowel. Where the picture suggests inflammation, colonoscopy with biopsies confirms the diagnosis and shows how extensive it is. Biopsy results take a few weeks and are discussed with you at follow-up.
Telling IBD apart from IBS
Many people are told they have a sensitive gut when in fact inflammation is present, and others are investigated repeatedly when their symptoms are functional. Objective testing separates the two quickly, which avoids both unnecessary treatment and missed diagnoses.
Ongoing care and NHS specialist services
Once a diagnosis is made, treatment is planned with you. Straightforward management can continue privately, while complex or advanced therapy such as biologic treatment is delivered through NHS specialist IBD services, with onward referral arranged where that is the right route for your care.

Crohn's and colitis FAQs
What is inflammatory bowel disease?+
Inflammatory bowel disease (IBD) describes long-term inflammation of the digestive tract, most commonly Crohn's disease and ulcerative colitis. It differs from irritable bowel syndrome because there is visible inflammation and tissue damage, which can be seen at endoscopy and measured on blood and stool tests.
What are the symptoms of Crohn's disease and ulcerative colitis?+
Common symptoms include persistent diarrhoea, blood or mucus in the stool, abdominal pain and cramping, urgency, fatigue, unintended weight loss and mouth ulcers. Symptoms often come and go in flares, and any of them lasting more than a few weeks should be assessed.
How is inflammatory bowel disease diagnosed?+
Assessment usually combines blood tests, a stool calprotectin test that measures bowel inflammation, and colonoscopy with biopsies. Laboratory analysis of biopsies takes a few weeks, after which the findings and a treatment plan are discussed with you.
