Tuberculosis itself does not cause darkening of the face; it may be due to an adverse reaction to anti-tuberculosis drugs or other factors.
Tuberculosis is an infection caused by the tubercle bacillus, resulting in a series of symptoms such as dry cough, night sweats (abnormal sweating after going to sleep and stopping after waking up), and weight loss.
Its damage to the human body is mainly reflected in the lungs, which can form an inflammatory reaction and cause such symptoms. Usually, it does not damage the skin, and Mycobacterium tuberculosis does not affect the skin’s pigmentation, so tuberculosis itself does not lead to darkening of the face.
It may be caused by the adverse reaction of anti-tuberculosis drugs or other factors. Anti-tuberculosis drugs such as isoniazid, rifampicin, etc. may affect the normal pigmentation of the skin and lead to a similar manifestation; in addition, long-term outdoor work and hereditary factors may also lead to darkening of the face.
Therefore, tuberculosis itself does not cause darkening of the face, it is recommended to consult a doctor in time for examination, according to the doctor’s instructions for appropriate treatment.
