Welcome to HCM,
In any wasting diseases ESR
is high but it is not always that your mother is having tuberculosis
or any other wasting disease.
Go for x-ray chest and find out that is there any lesion in her lungs.
Consult Physician and get all necessary investigations done.
Give her high nourishing diet, fresh fruits and more green veggies.
After report doctor will start treatment accordingly.
Ok and bye.
