My sister has hep c genotype 1. Just got it her viral load is very low. What are some holistic things she could do to keep it low?

No alcohol. Avoid any alcohol and avoid getting coinfected with hiv. The immune system works to control the virus so avoiding stress, eating healthy and no tobacco or any drugs may also help. Low viral loads should help lead to higher cure rates with antiviral treatment when she is ready. Low viral load does not predict slower rate of scarring (fibrosis).
