IBS
What is IBS (Irritable Bowel Syndrome)?
Irritable Bowel Syndrome (IBS), also known as irritable bowel, spastic colon, or mucous colitis, is a disorder characterized by abdominal pain and alterations in bowel habits. It is distinct from inflammatory bowel disease (IBD).
Are your fluctuating bathroom habits impacting your daily life? If so, you might be experiencing Irritable Bowel Syndrome (IBS). This condition causes abdominal pain, cramping, and changes in bowel patterns. IBS is classified as a functional bowel disorder rather than a disease, meaning that while colonoscopic examinations may appear normal, the colon’s behavior can vary significantly. Symptoms can range from mild to severe and typically include diarrhea, constipation, or both, accompanied by abdominal discomfort, bloating, and gas. These symptoms often temporarily improve after a bowel movement, highlighting the condition’s strong connection to psychological factors like stress, anxiety, or depression. IBS is more prevalent among women and can manifest at any age, though it often starts in adolescence or early adulthood. Dietary factors, such as consuming fatty foods or caffeinated beverages like coffee and tea, can exacerbate symptoms. Keeping a food diary can aid in identifying triggers, assisting doctors in diagnosing IBS through medical history and
excluding conditions like lactose or gluten intolerance or bowel infections. While there’s no specific test for IBS, managing symptoms often involves lifestyle adjustments like eating smaller, more frequent meals and increasing fiber intake to regulate bowel movements. Medications such as laxatives or antispasmodics like Hyoscyamine can also provide relief, while addressing underlying stress or mood disorders may require strategies like exercise, meditation, or antidepressant therapy. Remember, while IBS affects the abdomen, its roots often lie in psychological factors, emphasizing the mind-body connection in managing symptoms.
What Causes Irritable Bowel Syndrome?
The precise origins of IBS remain unclear, though it may follow bacterial or parasitic infections of the intestines (e.g., post infectious IBS) or be triggered by stress-induced heightened nerve activity between the gut and brain. It can emerge at any age but is more prevalent among women and less common in those over 50. About 10% to 15% of Americans report IBS symptoms, making it a primary reason for gastroenterologist referrals.
Symptoms of Irritable Bowel Syndrome
IBS symptoms vary from person to person, ranging from mild to severe, with diagnosis typically requiring symptoms at least three days per month over three months. Common manifestations include abdominal pain, cramps, gas, bloating, and altered bowel habits (IBS-D for diarrhea, IBS-C for constipation).
Exams and Tests for Irritable Bowel Syndrome
Diagnosing IBS generally relies on symptom assessment, although lactose-free diets and tests for celiac disease, anemia, or stool abnormalities may be used to rule out other conditions. Colonoscopy may be recommended based on age, symptoms, or abnormal test results.
Treatment of Irritable Bowel Syndrome
Treatment aims to alleviate symptoms, often involving lifestyle changes such as exercise and improved sleep, though no one-size-fits-all diet exists. Medications like anticholinergics, probiotics, antidepressants, or specific drugs for IBS-D or IBS-C may be prescribed, tailored to individual needs.
Outlook (Prognosis):
IBS can persist throughout life, varying in impact from manageable to disabling, but generally responds well to treatment without causing permanent intestinal damage or serious disease like cancer.
When to Seek Medical Advice:
Consult a healthcare provider if you suspect IBS or notice persistent changes in bowel habits that don’t resolve.
