  • Malnutrition
  • Reduced quality of life
Consequently, diagnostic testing becomes an important part of long-term management. IBS (Irritable Bowel Syndrome) One of the most common causes of chronic diarrhea is Irritable Bowel Syndrome. IBS is a functional digestive disorder that affects the large intestine. Although IBS does not cause permanent intestinal damage, it can significantly impact daily life. What Is IBS? IBS affects how the digestive tract functions. As a result, bowel movements may become irregular. Some individuals experience constipation, while others experience diarrhea-predominant IBS. Common Symptoms of IBS Frequent Loose Stools Patients may experience recurrent diarrhea. Abdominal Cramping Pain often improves after bowel movements. Bloating Abdominal fullness is a common complaint. Gas and Discomfort Digestive symptoms often fluctuate over time. Therefore, IBS should be considered when symptoms persist without an obvious infection. How Is IBS Diagnosed? There is no single test that confirms IBS. Instead, doctors often use diagnostic testing to rule out other conditions. Common investigations may include:
  • Stool Test
  • CBC
  • Thyroid Function Test
  • Inflammatory Markers
  • Food Allergy Assessment
Consequently, testing helps narrow down potential causes. Infection-Related Chronic Diarrhea Infections remain another important cause of persistent diarrhea. Although many infections resolve quickly, some may continue for weeks or months. Therefore, identifying infectious causes is critical. Bacterial Infections Certain bacteria can cause prolonged digestive symptoms. Examples include:
  • Salmonella

  • Shigella
As a result, stool culture testing may be recommended. Parasitic Infections Parasites may cause chronic diarrhea, particularly in certain environments. Symptoms may include:
  • Loose stools
  • Abdominal pain
  • Weight loss
  • Fatigue
Therefore, stool testing becomes essential for accurate diagnosis. Viral Infections Although viral infections are typically short-lived, some cases may contribute to prolonged digestive disturbances. Consequently, a comprehensive evaluation may be required.

Therefore, food-related causes should also be considered. Food Allergies Food allergies involve an immune system response. Common triggers include:

  • Eggs
  • Nuts
  • Seafood
  • Wheat

Additional Tests That May Be Recommended Depending on symptoms and medical history, healthcare providers may suggest additional investigations. Complete Blood Count (CBC) A CBC helps evaluate:
  • Infection
  • Anemia
  • Inflammation
Consequently, it often forms part of a comprehensive evaluation. Electrolyte Profile Chronic diarrhea can lead to loss of:
  • Sodium
  • Potassium
  • Chloride
Therefore, electrolyte testing is important. Thyroid Function Test Overactive thyroid function may sometimes contribute to chronic diarrhea. As a result, thyroid testing may be recommended.

  • Vitamin B12
  • Vitamin D
  • Iron
Liver Function Test (LFT) Digestive symptoms can occasionally be associated with liver-related conditions. Therefore, liver assessment may be included. Kidney Function Test (KFT) Persistent diarrhea may affect hydration and kidney function. Consequently, kidney health monitoring may be necessary. When Should You Seek Medical Attention?

Therefore, an urgent assessment may be necessary. Managing Chronic Diarrhea While Awaiting Diagnosis Although treatment depends on the underlying cause, certain measures may help reduce symptoms.
