Of course, avoid alcohol. I'm sure that's not an issue.
It sounds as though the medical condition you have exceeds general wellbeing and requires the care of a physician. I hope that you are receiving proper care and advice.
I found a couple of articles relevant to your combination of conditions although I recommend following your medical treatment.
With your concern about a low pH level, I thought you might find useful information in this Medline article titled Acidosis. The article describes Acidosis as a condition in which there is too much acid in the body fluids. It is the opposite of alkalosis (a condition in which there is too much base in the body fluids). The information suggests that liver failure can cause lactic acidosis or the buildup of lactic acid.
I do not find any studies about diet for a combination of chronic liver disease and low pH. I did find trusted information about nutrition for liver disease, but the recommendations could be quite different in your case. So, again, take this information to your physician to discuss it.
According to the U.S. National Institute of Health, some people with liver disease must eat a special diet. This diet helps the liver function and protects it from working too hard. Liver disease causes the body to struggle in processing proteins, and waste products may build up.
Suggested dietary changes for liver disease may include:
reducing the consumption of animal protein
increasing carbohydrates to be in proportion to protein
eat fruits, vegetables, and lean protein - avoiding high saturated fat animal meets
because the liver processes waste, avoid eating uncooked shellfish when suffering from liver disease
take any vitamins and medicines prescribed by your doctor
limit your salt intake
