Stomach TB, also known as abdominal tuberculosis, is a type of tuberculosis that affects the digestive system. While TB is commonly associated with the lungs, it can also infect other parts of the body, including the stomach and intestines. Recognising the symptoms early can help in getting timely treatment and preventing complications.
What Is Stomach TB?
Stomach TB occurs when Mycobacterium tuberculosis, the bacteria that causes TB, infects the stomach, intestines, or surrounding lymph nodes. It can develop after consuming contaminated food or milk, or when TB from the lungs spreads to the abdomen.
This condition can be tricky to diagnose because its symptoms often resemble other digestive disorders like irritable bowel syndrome (IBS), Crohn’s disease, or even stomach infections.
Key Symptoms of Stomach TB
Since stomach TB affects the digestive system, most symptoms are related to gut health. Here are the most common signs to watch for:
1. Persistent Abdominal Pain
Dull or cramping pain in the stomach that doesn’t go away
Pain may worsen after eating
2. Unexplained Weight Loss
Losing weight without trying
Loss of appetite
3. Digestive Issues
Diarrhoea (sometimes with mucus or blood)
Constipation (in some cases)
Feeling bloated or full quickly
4. Fever and Fatigue
Low-grade fever, especially in the evenings
Constant tiredness and weakness

5. Swelling in the Abdomen
Fluid buildup (ascites) causing a swollen belly
Enlarged lymph nodes that may be felt as lumps
6. Night Sweats
Excessive sweating at night, unrelated to room temperature
If you experience two or more of these symptoms for more than two weeks, it’s important to consult a doctor.
What Causes Stomach TB?
Stomach TB can develop due to:
Swallowing TB bacteria (through contaminated food or unpasteurized milk)
Spread from lung TB (if TB infection reaches the abdomen)
Weak immune system (HIV, diabetes, or malnutrition can increase risk)
How Does Stomach TB Affect Health?
If left untreated, stomach TB can lead to:
Bowel obstruction (due to scarring in the intestines)
Malnutrition (poor absorption of nutrients)
Peritonitis (infection of the abdominal lining)
Fistulas (abnormal connections between organs)
Early diagnosis and treatment can prevent these complications.
Tips for Managing Stomach TB
If diagnosed with stomach TB, following your doctor’s advice is crucial. Here are some additional ways to support recovery:
1. Follow the Prescribed TB Treatment
TB treatment usually involves 6-9 months of antibiotics.
Never skip doses, as incomplete treatment can lead to drug-resistant TB.
2. Eat a Nutritious Diet
High-protein foods (eggs, lentils, lean meats) help in healing.
Iron-rich foods (spinach, beans) prevent anaemia.
Small, frequent meals are easier to digest.
3. Stay Hydrated
Drink plenty of fluids to prevent dehydration from diarrhoea.
4. Rest and Avoid Stress
TB weakens the body, so adequate rest is essential.
5. Monitor Symptoms
Keep track of any new or worsening symptoms and inform your doctor.
When to See a Doctor?
If you experience:
Unexplained weight loss + fever + stomach pain
Blood in stool or persistent diarrhoea
Severe bloating or vomiting
It’s best to consult a gastroenterologist for proper testing.
Conclusion
Stomach TB is treatable if detected early. If you or a loved one has persistent digestive issues along with fever and weight loss, don’t ignore the signs. Early medical intervention can help in a full recovery.
