Irritable Bowel Syndrome (IBS) in Oxford, Banbury & Aylesbury

Dr Udit Mittal provides consultant-led diagnosis and management of Irritable Bowel Syndrome across Oxfordshire and Buckinghamshire

Irritable Bowel Syndrome (IBS) is a common long-term condition affecting how the bowel functions. It may cause abdominal pain, bloating and changes in bowel habit such as diarrhoea, constipation, or a mixture of both.
Although IBS can significantly affect quality of life, it is not dangerous, does not damage the bowel and does not increase the risk of bowel cancer.
IBS is recognised as a disorder of gut–brain interaction, meaning the bowel becomes more sensitive and its movement less predictable. Symptoms are genuine and manageable with the right structured approach.
For patients experiencing IBS symptoms in Oxfordshire, consultant-led assessment helps confirm the diagnosis and provide a personalised management plan.

What Symptoms Can IBS Cause?

• • Recurrent abdominal pain or cramping

• • Pain often related to opening the bowels

• • Bloating or visible abdominal distension

• • Diarrhoea (IBS-D)

• • Constipation (IBS-C)

• • Alternating diarrhoea and constipation (IBS-M)

• • Urgency

• • Feeling of incomplete bowel emptying

• • Passage of mucus

Symptoms often fluctuate and may worsen during periods of stress, after certain foods, or following a gastrointestinal infection.

What Causes IBS?

There is no single cause. IBS is thought to result from a combination of factors:

Increased Gut Sensitivity

The bowel becomes more sensitive to normal digestion and stretching.

Altered Bowel Movement Patterns

Changes in how quickly or slowly the bowel moves.

Gut–Brain Interaction

The digestive system communicates closely with the nervous system. Stress can influence symptoms, although IBS is not “psychological.”

Post-Infectious Changes

Some individuals develop IBS after gastroenteritis.

Gut Microbiome Changes

Alterations in gut bacteria may contribute in some cases.
IBS reflects altered function rather than structural damage.

How Is IBS Diagnosed?

IBS is diagnosed using a positive clinical approach, as recommended by UK and international guidelines.
Assessment typically includes:

• • Detailed symptom history

• • Physical examination

• • Limited blood test
  • Stool tests where appropriate

Tests may be performed to exclude:

• • Coeliac disease

• • Inflammatory bowel disease

• • Other treatable conditions

In the absence of warning signs, extensive investigations are usually unnecessary.

When Should Symptoms Not Be Assumed to Be IBS?

Prompt medical review is required if you experience:

• • Rectal bleeding

• • Black stools

• • Unintentional weight loss

• • Anaemia

• • Persistent night-time symptoms

• • New bowel symptoms after age 50

• • Strong family history of bowel cancer or IBD – consider GI cancer screening

These features do not automatically indicate serious disease but require assessment.

Treatment of IBS

There is no single treatment that works for everyone. Management is individualised.

Lifestyle & Eating Habits

• • Regular meals

• • Avoiding long gaps between meals

• • Reducing caffeine, alcohol and fizzy drinks

• • Maintaining hydration

• • Regular physical activity

Fibre

• • Soluble fibre (e.g. psyllium) may help

 

• • Insoluble fibre may worsen bloating in some individuals

Dietary Approaches

• • Mediterranean-style diet

• • Low FODMAP diet (with dietitian guidance)

Medications (Symptom-Directed)

For Abdominal Pain

• • Antispasmodics

• • Peppermint oil

For Diarrhoea

• • Loperamide

• • Bile acid binders where appropriate

For Constipation

• • Osmotic laxatives

• • Fibre supplementation

For Persistent PainLow-dose neuromodulators may help regulate gut pain signalling.

Psychological & Gut-Focused Therapies

• • Cognitive behavioural therapy

• • Gut-directed hypnotherapy

These can be particularly effective in long-standing or severe IBS.

Probiotics

If trialled, use one product at a time for several weeks and continue only if improvement occurs.

When Should You See a Gastroenterologist?

• • Symptoms persist despite first-line measures

• • Warning features are present

• • Symptoms significantly affect daily life

• • Tailored dietary or medication strategies are required
