Hi there, I understand your concerns.
There maybe various causes of raised TG levels. So a complete history would be needed for ruling out secondary causes of high TG.
Along with the medication, physical activity, avoidance of alcohol and smoking, avoiding food rich in saturated fats should be the best way forward.
Next Steps
Consult for detailed history.
Get following tests:
HbA1C,
Thyroid Profile prior to consultation.
