Key Points from the Article

• Awareness Month:
• • April is recognized as IBS Awareness Month to promote understanding of this common yet often stigmatized gastrointestinal disorder.
• Definition and Nature:
• • IBS is a chronic, generally lifelong, functional gastrointestinal disorder characterized by a disrupted gut-brain connection.
  • It involves how the gut and brain interact, leading to symptoms without structural damage to the intestines.
• Prevalence in India:
• • A 2023 consensus by the Indian Neurogastroenterology and Motility Association estimates IBS prevalence in India ranges from 0.4% to 4.2%.
  • This figure may underestimate the true disease burden due to underreporting and lack of awareness.

• Types of IBS:
• • IBS with Constipation (IBS-C): Characterized by predominant constipation and abdominal discomfort.
  • IBS with Diarrhea (IBS-D): Marked by frequent diarrhea alongside abdominal discomfort.
  • IBS with Mixed Bowel Habits (IBS-M): Features alternating diarrhea and constipation with abdominal discomfort.
  • Undefined IBS (IBS-U): Symptoms vary and do not fit neatly into other categories.
• Symptoms:
• • Common symptoms include abdominal discomfort, bloating, diarrhea, constipation, or alternating bowel habits.
  • Symptoms can significantly impact daily life and social functioning.
• Diagnosis:
• • No definitive test exists; diagnosis relies on a complete medical history and symptom assessment.
  • Physical exams and tests like blood tests, stool tests, and breath tests (for bacterial overgrowth) may be conducted.
  • Imaging tests such as colonoscopy, upper endoscopy, or scans may be used to rule out other conditions.
• Comorbidities:
• • Many IBS patients experience coexisting chronic pain conditions like fibromyalgia, chronic pelvic pain, or chronic fatigue syndrome.
  • Mental health issues such as anxiety, depression, and sleep disturbances are also common among IBS sufferers.
• Treatment Approaches:
• • Focuses on symptom management rather than a cure.
  • Lifestyle Modifications: Include regular exercise, 7-9 hours of sleep nightly, and stress-reducing relaxation techniques.
  • Medications: Options include fiber supplements, laxatives, pain relievers, antispasmodics, probiotics, or antidepressants, tailored to symptoms.
  • Treatment varies based on individual symptom profiles.
• Key Distinctions:
• • IBS does not increase the risk of colon cancer, unlike some other gastrointestinal conditions.
  • It differs from Inflammatory Bowel Disease (IBD), which involves inflammation and structural changes in the gut.
• Public Health Advice:
• • Individuals with symptoms should consult healthcare providers for accurate diagnosis and tailored treatment plans.
  • Early diagnosis and management can improve quality of life and reduce healthcare burdens.
