Irritable Bowel Syndrome (IBS)
Irritable Bowel Syndrome (IBS) is a common, long-term digestive system issue, leading to discomfort in daily life. Dr Nadir Abbas, an award-winning NHS Consultant and IBS specialist, offers a clear, rule-out diagnostic approach to ensure your symptoms aren’t caused by other conditions & to provide you with a tailored treatment plan.
What is Irritable Bowel Syndrome (IBS)?
Irritable Bowel Syndrome (IBS) is a common, long-term condition that affects how your digestive system works. It is known as a functional disorder, meaning that while the bowel appears normal on tests, the way the gut and brain communicate is out of sync, making your digestive system oversensitive.
Dr Nadir Abbas is an IBS specialist who rules out your IBS the right way, ensuring your symptoms are not caused by more serious conditions.
As Seen On
Types of Irritable Bowel Syndrome
The four main types of IBS are:
IBS-C (Constipation Predominant)
Characterised by infrequent bowel movements or hard, lumpy stools.
IBS-D (Diarrhoea Predominant)
Characterised by frequent, loose, or watery stools and sudden urges to go.
IBS-M (Mixed)
A combination where you alternate between periods of constipation and diarrhoea.
IBS-U (Unclassified)
Symptoms vary significantly and do not fit neatly into the other three categories.
Common Symptoms of IBS
IBS symptoms often come and go in waves, known as flare-ups. Common daily signs include:
- Pain or cramping in the abdomen.
- Frequent bloating or wind passing.
- Significant changes in your bowel habits.
- The presence of clear or white slime during bowel movements.
Key Causes or Triggers of Irritable Bowel Syndrome
As an expert IBS specialist, Dr Abbas looks for these common root causes to help understand your flare-ups:
Extra Sensitive Nerves
The nerves in your bowel might be overly sensitive. This means normal digestion or small amounts of gas can feel extremely painful.
Muscle Spasms
Your gut muscles might squeeze too hard and too fast, causing diarrhoea. Or, they might squeeze too weakly, causing hard constipation.
Past Infections
Many patients develop IBS shortly after a very bad stomach bug or severe food poisoning.
Unbalanced Gut Bacteria
The healthy, natural microbes and bacteria living inside your bowel might be out of balance.
Stress and Worry
While stress does not directly cause IBS, high anxiety or difficult life events can deeply upset your gut and trigger severe symptoms.
How Our Specialist Rules Out Irritable Bowel Syndrome
Dr Nadir Abbas uses a structured process to rule out IBS & ensure your symptoms are not caused by more serious conditions like IBD or Coeliac disease. His diagnostic pathway includes:
Clinical Consultation & Risk Assessment
Dr Nadir conducts a 30-minute private consultation to identify red flag symptoms and review your medical history.
Same-Day, Advanced Blood Screening
Detailed tests are performed to check for anaemia and nutritional deficiencies that IBS alone would not typically cause.
Faecal Calprotectin Test
This specific stool test checks for gut inflammation; a low result helps Dr Nadir rule out IBD (such as Crohn’s or Colitis) and confirm an IBS diagnosis.
Coeliac Disease Testing
Before diagnosing IBS, he makes sure that your symptoms are not due to an immune system problem with gluten.
Targeted Investigations (If Required)
If results are unclear, Dr Nadir uses his expertise in advanced imaging to examine the bowel lining directly and exclude other serious gastrointestinal issues.
Gastroenterologist-Led IBS Management
Dr Nadir Abbas, a leading IBS specialist, provides a multidisciplinary approach that moves beyond basic advice to offer advanced, evidence-based relief.
Dietary Therapy
Dr Nadir works with specialist dietitians to implement the Low-FODMAP diet, which is clinically proven to reduce bloating and pain.
Advanced Medicine
Treatment is given according to your specific IBS type using modern gut-motility medications and antispasmodics to settle your system.
Brain-Gut Support
For complex cases, he incorporates gut-directed therapies to manage the communication between your nervous system and your gut.
Advanced Rule Out & IBS Treatment Approach by Dr Nadir
The most critical step in treating IBS is making sure it is, in fact, IBS. Many serious gut issues hide behind similar symptoms.
Dr Abbas uses a strict rule-out approach. Before confirming IBS, he runs advanced tests to absolutely rule out serious conditions like Crohn’s Disease, Ulcerative Colitis, Coeliac Disease, and colon cancer. Once we know your bowel is safe from disease, we can confidently start your IBS recovery plan.
