Thanks for using Healthcaremagic,
Your father is having multiple medical problems and taking many drugs.
How much liver enzymes are elevated and what are the numbers for platelets and need to be correlated clinically and treatment depends on cause.
Many diabetic and cholesterol
medicines are metabolized in liver can lead to elevation of liver enzymes SGPT and SGOT and logically dose of of such drug needs to be reduced or stopped altogether.
Infection like viral fever
can increase liver enzymes this needs to be treated accordingly.
Other common cause could be Fatty liver
which can be easily diagnosed with Ultrasound
This is good that aspirin is stopped please repeat liver function and platelet count
if count is still low and associated with bleeding then supportive transfusion(PRP) may be required.
Please consult Internal medicine specialist treatment depends on cause.
Hope this helps,
Dr.Akhilesh Dubey M.D.
