Hi welcome to Health care magic forum.
Thanks for calling H.C.M.Forum.
Your father is suffering from
tuberculosis, we are in doubt of what diet we should give him in breakfast, lunch, and dinner.
It took 6 months to get the diagnosis. Clinically it is proved, and the test reports are awaiting.
These days there is nothing to worry about the tuberculosis, there are several drugs for tuberculosis and several combinations recommended for the disease depending upon the age and weight of the patient, for complete recovery.
But the treatment should be given after confirming the disease only so leave about the treatment to your doctor.
Regarding diet you can give any diet he is interested, it is the only disease, where there is chance of different menus.
Give im light breakfast like foods with little spices, and oils.
In the lunch, give him an egg daily, and you can give nonvegetarian foods as well.
In the night you can give him light dinner, having green leafy vegetables, pulses, and any vegetables.
Give any food upto his ability to eat, slowly appitite will increase, don't ebberass him in the meanwhile, for food in excess.
i hope you got my point. thank you.
