Chronic loose or poorly formed stools can occur due to several conditions, including irritable bowel syndrome (IBS-D), food intolerances (such as lactose intolerance), chronic intestinal infections, malabsorption disorders (including celiac disease), inflammatory bowel disease,
thyroid disorders, or disturbances in the normal gut microbiota. A detailed history and evaluation are required to determine the exact cause.
Important points include:
Duration of symptoms
Frequency of bowel movements
Presence of blood, mucus, abdominal pain, bloating, weight loss, fever, or nocturnal diarrhea
Dietary triggers
Recent travel, antibiotic use, or medication history
Initial investigations may include:
Complete blood count (CBC)
Stool routine examination and stool culture if indicated
Thyroid function tests
Celiac disease screening
Inflammatory markers and other tests based on clinical findings
Treatment depends on the underlying cause and should not be started without proper evaluation. Maintaining adequate hydration, avoiding known dietary triggers, and seeking consultation with a gastroenterologist are recommended.
