A persistent cough, unusual fever during the night, fatigue that is not like normal pregnancy fatigue — these may be early symptoms of tuberculosis (TB) for some pregnant women. The term causes distress for many women who are expecting their babies, but the good news is that tuberculosis is treatable during pregnancy, and it is incredibly safe to treat it during pregnancy rather than let it go untreated.
Pakistan has one of the highest burdens of TB in the world with the fifth position in the world with approximately 6% of the cases around the globe. TB is a high-risk pregnancy condition. This makes it particularly important for women in Pakistan be aware of the disease. It is estimated that around 200,000 women worldwide develop tuberculosis during pregnancy or post-delivery every year.

1.What Is Tuberculosis?
Tuberculosis refers to the diseased caused by Mycobacterium tuberculosis. Sometimes, it attacks the lungs (pulmonary TB) but also the lymph nodes, spine, kidney, and peritoneum (extrapulmonary TB). Contagion occurs through the air. An active and untreated TB patient who coughs or sneezes is capable of spreading the disease but it is not transmitted through utensils and touch.
Not everyone infected with tuberculosis gets sick.
Doctors divide TB into:
1. Latent TB infection, the bacteria are there but inactive. Person reports good health. There are no symptoms and there is no risk of transmitting the disease, even to babies.
The second type is active TB disease.
2. The bacteria are multiplying and an individual has health problems and may infect others. Pregnancy modifies the immunological status of a woman. The immune system becomes competent enough to protect the developing fetus. This shift also increases the risk of transformation from latent to active TB infection, especially during the postpartum period. This is why antenatal screening for TB is extremely important in such countries as Pakistan where TB prevalence is high.
2. Why Pregnancy Changes the Picture:
Pregnancy affects a woman’s immune response as her body undergoes changes to provide the optimal conditions for the developing fetus. This could make her organism more prone to the reactivation of latent TB infection and developing symptoms of active disease. Therefore, effective TB screening during pregnancy in countries with a high burden of TB infection is crucial.
3. Symptoms of Tuberculosis During Pregnancy.
The issue with TB in pregnant women is that the early signs can mimic the common symptoms of pregnancy. It’s important to note the essential differences:
1. Coughing for more than 2-3 weeks should be treated as the most important warning sign; normal pregnancy does not cause long-term coughing,
2. Slight fever that often gets worse at night,
3. Heavy sweating during the night,
4. Losing weight suddenly or not gaining enough weight,
5. Continuous tiredness that does not improve with rest,
6. Lack of appetite.
7. Chest pain or shortness of breath.
8. Coughing blood-stained sputum, which means that TB is at an advanced stage, and help is needed quickly.
If TB has reached other organs, symptoms may also include swollen lymph nodes, back pain, and abdominal swelling; remember to tell your doctor about any of these symptoms, especially if you have recently been in contact with a person suffering from TB.
🩺 اہم علامات — ایک نظر میں
دو ہفتوں سے زیادہ رہنے والی کھانسی، شام کے وقت ہلکا بخار، رات کو پسینہ آنا، وزن کا کم ہونا اور بلا وجہ تھکاوٹ — یہ عام حمل کی علامات نہیں ہیں۔ اگر آپ کو یہ علامات محسوس ہوں تو فوری طور پر اپنے معالج سے رجوع کریں۔ ٹی بی کا بروقت علاج ماں اور بچے دونوں کے لیے محفوظ اور مؤثر ہے۔
4. Risk Factors Of Tuberculosis In Pregnancy:
You can have a good chance of suffering from active TB disease in case you:
Have been exposed to someone who has been reported to have active TB disease
Suffer from diseases such as HIV, diabetes, or other diseases that are capable of affecting the immune system adversely
Have a lack of food, or you are nearly starving
Spend time with many people in shared living quarters or work in TB -favorable conditions (a hospital, shelter, etc.)
Are from areas plagued by TB pathogens
5. How Tuberculosis Is Diagnosed During Pregnancy:
It is often worried that TB testing might not be safe during pregnancy. This is unwarranted fear as all standard TB tests have safe alternatives:
TB skin test (Mantoux / TST) — Limited amount of test material is injected under the skin of forearm, and then the test is interpreted after 2–3 days. It is safe and accepted as valid method during pregnancy.
TB blood test (IGRA) — A blood test that determines how well the immune system reacts to TB proteins. It is safe in pregnancy and the results do not depend on previous BCG vaccination unlike the skin test.
Sputum smear, culture and GeneXpert (CBNAAT) — In suspected cases of TB,
Sputum sample is tested and cultured. Certain testing facilities in Pakistan offer GeneXpert MTB/RIF, a fast molecular testing method which determines the fact of TB and the level of rifampicin resistance.
Chest X-ray — Safe through pregnancy but must be carried out with the help of lead shielding of abdomen and pelvis so that there is no danger for the child.
6. Can Tuberculosis Harm the Baby?
Not taking care of active tuberculosis in mothers raises the chances of the baby being born underweight as well as developing tuberculosis. For this reason, the doctors prefer to treat active tuberculosis instead of delaying it. On the other hand, there is very low risk connected with the administration of the tuberculosis medicine.
7. Safe Treatment During Pregnancy:
Active TB disease – standard first-line treatment used worldwide during pregnancy.
This is typically delivered through DOTS (Directly Observed Treatment, Short-course), the WHO-recommended model to ensure the full course is completed correctly.
When isoniazid is prescribed, your doctor will typically add vitamin B6 (pyridoxine) alongside it to prevent nerve-related side effects
Your obstetrician and tuberculosis doctor will keep track of the functioning of your liver and the growth of the baby all along the way. Any changing, halting or initiating of tuberculosis medication should take place only after consultation with the physician.
Treatment of inactive tuberculosis would usually be delayed until two to three months after childbirth unless the patient belongs to the high-risk group which may require the initiation of treatment earlier.
دوا کے بارے میں یقین دہانی
ٹی بی کی معیاری ادویات حمل میں محفوظ سمجھی جاتی ہیں اور نال کے ذریعے بچے کو کوئی نقصان دہ اثر نہیں پہنچاتیں۔ علاج بند کرنے یا خود سے دوا تبدیل کرنے سے گریز کریں۔
8. Breastfeeding While Taking TB Treatment:
Mothers taking standard TB medication can continue breastfeeding almost without exception, as only negligible amounts of the drug gets into breast milk.
One funny side effect of rifampicin is that it can change the colour of breast milk, urine, tears, and sweat to light orange — which is harmless.
9. Urgent Red Flags: When to Seek Immediate Medical Care.
If you experience any of the following symptoms, seek medical care immediately:
- A cough lasting over two weeks without Improvement,
- Coughing blood,
- High fever with chills,
- Breathing problems or
- Chest pain, considerable weight loss.
10. How to Prevent Tuberculosis During Pregnancy:
Make sure you ask about TB screening during routine antenatal visits, especially if you reside in high TB burden area like Pakistan.
- If someone in your family is diagnosed with TB, make sure you get tested whether you feel alright or not.
- Complete the full course of TB treatment — stopping early is how drug-resistant strains like MDR-TB (multidrug-resistant) and XDR-TB (extensively drug-resistant) develop.
- Make sure you eat healthy food, rich in iron and protein.
- Ensure adequate ventilation in your home, particularly if the household has been a historical hotspot for TB.
BCG Vaccination for the Newborn: In high-burden countries like Pakistan, babies receive the BCG vaccine at birth regardless of the mother's TB history. If you had active TB during pregnancy, discuss any additional newborn monitoring with your pediatrician.
11. Frequently Asked Questions (FAQ):
Q1. Does the existence of tuberculosis in a pregnant woman have adverse effects on the baby?
The existence of TB that has not been treated may lead to complications such as low birth weight and, in certain cases, transmission of the bacteria both before and soon after delivery. Hence, it is always better to seek treatment for the disease.
Q2. Is it safe for pregnant women to be prescribed TB medication?
Yes. Although isoniazid, rifampicin, and ethambutol will cross through to the placenta, there is no evidence that they pose any risks for the unborn baby. Vitamin B6 (pyridoxine) is typically prescribed alongside isoniazid to prevent nerve-related side effects, and liver function is monitored throughout treatment.
Q3. Should mothers avoid breastfeeding if they are taking TB medicine?
In most cases, mothers do not need to quit breastfeeding as the amount of the drugs in the milk is too small to have negative effects on the baby.
Q4. Is performing an X-ray on the lungs safe for pregnant women?
Yes, a woman can undergo an X-ray at any stage of pregnancy because the radiation dose is small.
Q5. In what way does TB differentiate from routine pregnancy exhaustion?
Average tiredness reduces through rest and does not include coughing. TB should be suspected when tiredness is accompanied by coughing for 2-3 weeks, nighttime fever, sweating at night, or unexplained loss of weight.
Q6. Should my infant receive the BCG vaccine at birth if I contracted TB during pregnancy?
In countries with high disease burden like Pakistan, newborns have to undergo BCG immunization regardless of whether or not the mother had a prior TB infection. Consult with your pediatrician about further assessment if you experienced active TB.
Q7.Where can pregnant women get TB testing in Pakistan?
Government-run BHUs and NTP-affiliated centers across Pakistan offer free or low-cost TB testing, including GeneXpert MTB/RIF where available. If you're unsure where to start, you can message our clinic on WhatsApp for guidance on your nearest testing facility.
12. Key Points:
Important points: It is always abnormal to have a cough that lasts longer than 2-3 weeks in pregnancy. All conventional tests for tuberculosis are safe during pregnancy. Untreated active tuberculosis poses more risk for the baby than the therapy. Breastfeeding is usually safe to continue.
