Why is pregnancy not recommended in patients with active TB?

Pregnancy in patients with active TB may have a double adverse effect on the mother and the foetus, so pregnancy is not recommended for this group of patients. For example, when a patient with active TB becomes pregnant, the growth of TB bacteria may be harmful to the pregnant woman’s body; she may also be susceptible to blood-borne TB or even systemic TB after delivery, and the foetus may become infected with TB or be malformed as a result of improper treatment during pregnancy.
In addition, patients with active TB need to take anti-tuberculosis drugs, some of which can be toxic to the foetus and cause damage. Therefore, patients with active TB should consider pregnancy after they have been actively cured and have been off their medication for six months.
