Hi Zamryz! Welcome to HealthcareMagic,
Your LFT- ALT level should not be read in isolation. What are the levels of bilirubin
& other liver
enzymes? You are also on anti-hypertension
medications few of them may cause elevation of liver enzymes. The best way, which you asked, is not to reduce ALT yourself, but discuss it with your physician. I think, after a confirmatory LFT for isolated ALT elevation, your doctor may modify/suggest your treatment.
