Gastrointestinal Tuberculosis

Gastrointestinal tuberculosis (GI TB) is a type of tuberculosis that affects the digestive system, including the stomach and intestines. It’s caused by the bacteria Mycobacterium tuberculosis, the same bacteria that cause pulmonary tuberculosis, but it affects the digestive tract instead. Understanding GI TB, its symptoms, causes, diagnosis, and treatment is essential for early detection and effective management.

Types of Gastrointestinal Tuberculosis:

1. Intestinal Tuberculosis: Affects the intestines, including the small intestine and colon.
2. Peritoneal Tuberculosis: Involves the lining of the abdominal cavity, called the peritoneum.
3. Tuberculous Colitis: Specifically affects the colon.
4. Tuberculous Enteritis: Affects the small intestine.

Causes of Gastrointestinal Tuberculosis:

1. Infection with Mycobacterium tuberculosis bacteria through contaminated food or water.
2. Weakened immune system, such as in HIV/AIDS or due to certain medications.
3. Close contact with individuals infected with tuberculosis.
4. Poor living conditions and overcrowding.
5. Malnutrition and poor dietary habits.
6. Smoking and substance abuse, which weaken the immune system.
7. Chronic diseases like diabetes or kidney disease.
8. Travel to regions with high tuberculosis prevalence.
9. Lack of access to healthcare and preventive measures.
10. Occupational exposure in healthcare settings.
11. Alcohol abuse, which weakens the immune system.
12. Age, as older adults are more susceptible to infections.
13. Genetic predisposition to tuberculosis.
14. Previous history of tuberculosis infection.
15. Immunosuppressive therapies, such as for organ transplants.
16. Poor hygiene practices.
17. Underlying lung diseases.
18. Crowded living conditions.
19. Poverty and socioeconomic factors.
20. Drug-resistant strains of tuberculosis.
