hello zara, you have not given complete medical and personal history of your aunty.please tell her age, whether she is diabetic ,whether on some medication etc. From the precise information given by you it might be possible that her cholesterol
/ lipid levels may be raised i.e dyslipidemia
. you can have her following tests done:-
1. Blood sugar (Fasting and PP)
2. Lipid Profile
3. S. Urea
4. S. Creatinine
6. Urine (R/M)
7. Fundoscopy done by ophthalmologist.
The test adviced by your doc is TMT and not TNT. It is a Tread Mill Test.
Hope this may be useful to you in planning treatment of your aunt. thanks.
