Hi Kittu, Welcome to HealthcareMagic Forum.
You haven't mentioned what exactly are your Mother's symptoms? High Levels of IgG
antibody of TB suggests
Chronic Infection. If IgM values were to be higher it suggests a New Infection. Since it is confirmed she will have to take Anti-TB medications for 3 to 6 Months to one complete year for complete recovery as there will be chances of Relapse of the Infection is the course is not completed. Take her for regular follow up.
She should eat healthy nutritious balanced diet which should include fresh fruits and Green leafy vegetables along with
Protein rich foods like
Eggs, milk, chicken, fish etc.. As this will improve her
immunity and will help her fight the Infection better. She should be exercising regularly and taking adequate rest.
I Wish her Good Health, Take Care.
