Bleeding after three months of tuberculosis treatment may be a normal phenomenon, or it may be due to irregular medication or improper treatment. 1. Normal phenomenon: Due to the long course of tuberculosis, if the patient’s condition is more serious, the treatment time is more than three months, therefore, there will still be bleeding in the course of treatment, but the overall clinical symptoms have been reduced compared with the previous one, which is considered to be a normal phenomenon. 2. Irregular use of medication: If patients with tuberculosis usually have improper use of medication, such as omission, underdose, etc., to a certain extent, it will affect the therapeutic effect, and then there will be tuberculosis treatment for three months and still bleeding phenomenon. 3. Improper treatment: Secondly, bleeding after three months of tuberculosis treatment may also be due to improper treatment, which means that the current treatment measures cannot control the disease, and timely adjustment of the treatment program is needed, such as replacing or adding drugs, or adopting surgical treatment. It is recommended that patients who are still bleeding after three months of tuberculosis treatment should go to the hospital for a follow-up examination to clarify the specific cause of the bleeding and then cooperate with the doctor to carry out standardized treatment.
