Clinical Causes: Inhalation of airborne bacteria, leading to primary lung infection that can spread to the digestive organs Contaminated food or water sources containing Mycobacterium tuberculosis Direct contact with infected individuals through oral or fecal routes Hematogenous spread from a primary tuberculosis focus elsewhere in the body Immunocompromised states, such as HIV/AIDS, increasing susceptibility

Key Symptoms: Persistent abdominal pain Unexplained weight loss Chronic diarrhea or altered bowel habits Fever and night sweats Loss of appetite Nausea and vomiting Palpable abdominal mass in some cases Signs of intestinal obstruction or bleeding

Diagnosis Path: Diagnosis involves a combination of clinical evaluation, laboratory tests, and imaging studies. Physicians may perform endoscopy with tissue biopsies to identify granulomatous inflammation or presence of bacteria. Additional diagnostic approaches include: - Histopathological examination - Acid-fast bacilli (AFB) staining - Cultures for Mycobacterium tuberculosis - Imaging techniques such as CT scans to assess the extent of organ involvement - Tuberculin skin test (Mantoux test) or interferon-gamma release assays (IGRAs)

Treatment Protocols: Treatment generally involves a long-term course of multiple antibiotics to eradicate the infection. Standard therapy includes: - First-line anti-tubercular drugs such as isoniazid, rifampicin, ethambutol, and pyrazinamide - Duration of therapy typically lasts 6-12 months, depending on severity and response - Close medical supervision to monitor treatment effectiveness and manage potential side effects - Supportive care, including nutritional support and management of complications - In some cases, surgical intervention may be necessary to address strictures or perforations
