@nisey22157 Hello and welcome to Mayo Connect. We are patients and caregivers living with a variety of medical conditions who try to help and support one another along the way.

When you say "doctor says treating the liver will help" can you explain a little? Is this your primary provider, a specialist, a naturopath...
Have you possibly been told that you have a "fatty liver" or other liver disorder?
And when you say you struggle with losing weight, is this a new thing, or has it always been a problem for you?

All that said, the whole issue of doing a liver cleanse is controversial. The liver can heal itself over time (if not permanently damaged by scarring or cirrhosis) by avoiding all the things that make it work harder - here is a very good, easy to read article explaining:

I would like to hear what steps you have taken on your journey so far.
