What is Irritable Bowel Syndrome?
Irritable Bowel Syndrome (IBS) is a common digestive disorder that affects the large intestine, causing symptoms like abdominal pain, bloating, gas, diarrhea, and constipation. It is a chronic condition with no known cure, but symptoms can be managed through diet, stress reduction, and medications.
IBS does not cause permanent damage to the intestines but can significantly impact daily life. Triggers vary among individuals and may include certain foods, stress, or hormonal changes. Lifestyle changes, probiotics, and a high-fiber diet often help in managing symptoms effectively.
Common Symptoms of IBS
Abdominal Pain & Cramping - Usually relieved after a bowel movement.
Bloating & Gas - Feeling of fullness and excessive gas.
Diarrhea (IBS-D) - Frequent, loose, or watery stools.
Constipation (IBS-C) - Hard, infrequent stools with difficulty passing.
Alternating Bowel Habits (IBS-M) - Switching between diarrhea and constipation.
Mucus in Stool - Presence of white or clear mucus in bowel movements.
Urgency to Defecate - Sudden and strong urge to use the restroom.
Other Symptoms of Irritable Bowel Syndrome (IBS)
Incomplete Bowel Movements
Nausea
Fatigue
Food Intolerance
Lower Back Pain
Frequent Urination
What are the Causes of IBS?
Irritable Bowel Syndrome (IBS) has no single cause, but several factors contribute to its development. It is often linked to digestive issues, nervous system problems, and gut sensitivity.
Causes of IBS-
Abnormal Gut Motility - Irregular contractions of the intestines cause diarrhea or constipation.
Nerve Dysfunction - Increased sensitivity in the gut leading to pain and discomfort.
Gut Microbiome Imbalance - Changes in gut bacteria affecting digestion.
Food Triggers - Certain foods like dairy, spicy foods, or gluten can worsen symptoms.
Stress & Anxiety - Emotional stress can affect gut function and trigger IBS flare-ups.
Hormonal Changes - Women often experience worsened symptoms during menstruation.
Infections or Gut Inflammation - Prior gastrointestinal infections or inflammation can lead to IBS.
Different Types of IBS
Irritable Bowel Syndrome (IBS) is classified into different types based on the predominant bowel habits. Each type has distinct symptoms, but all involve chronic digestive discomfort.
Types of IBS-
IBS-C (IBS with Constipation) - Hard, infrequent stools with difficulty passing.
IBS-D (IBS with Diarrhea) - Frequent, loose, or watery stools.
IBS-M (Mixed IBS) - Alternating between constipation and diarrhea.
IBS-U (Unclassified IBS) - Symptoms that don’t fit into the other categories.
Diagnosis of IBS
IBS is diagnosed based on symptoms, medical history, and ruling out other digestive conditions. There is no single test for IBS, so doctors use specific criteria and examinations.
1. Medical History & Symptom Assessment
Doctors evaluate bowel habits, pain patterns, diet, and stress levels to identify IBS triggers.
2. Rome IV Criteria for IBS
IBS is diagnosed if abdominal pain occurs at least once a week for three months, along with-
Pain linked to bowel movements
Changes in stool frequency
Changes in stool form
3. Physical Examination
Doctors check for bloating, tenderness, and other digestive issues.
Tests for IBS
Tests help rule out infections, food intolerances, and serious conditions like IBD or celiac disease.
1. Stool Tests
Used to check for infections, inflammation, or blood in the stool.
Fecal Occult Blood Test (FOBT) - Detects hidden blood.
Calprotectin Test - Identifies inflammation.
2. Blood Tests
Helps rule out anemia, celiac disease, or infections.
3. Colonoscopy or Sigmoidoscopy
Used for severe cases to check for colon inflammation, polyps, or other conditions.
4. Hydrogen Breath Test
Diagnoses lactose intolerance or small intestinal bacterial overgrowth (SIBO).
5. Imaging Tests (If Needed)
X-ray, ultrasound, or CT scan may be used to rule out other digestive problems.
Once other conditions are excluded, IBS is diagnosed based on symptoms.
Conclusion
Irritable Bowel Syndrome (IBS) is a common but manageable digestive disorder that affects bowel habits and causes discomfort. While it has no cure, symptoms can be controlled through lifestyle changes, diet modifications, stress management, and medications. Early diagnosis and proper management help improve quality of life, allowing individuals to live comfortably with the condition. If symptoms persist or worsen, consulting a doctor is essential to rule out other serious conditions.
