high acidity and not sure where to go next

I have done 5 Liver Flushes and got out heaps of stones but also lost alot of weight and now under 50 kilos. I have low iron and proteins and my kidneys are not flushing correctly even though I did a kidney cleanse with a herbal tincture two flushes ago. I dont have any back pain. It has been suggested that I am not absorbing nutrients but I am not sure what to do next. I am also feeling nauseous after the Liver Flushes and it takes my system three weeks to be back on track so I am reluctant to keep doing the flushes until i can stablise my weight. But probably my greatest concern is that my urine PH is totally acid even though I have a full vegan, Sugar free, gluten free diet. appreciate guidance. Tweet
