Depending on the degree of cirrhosis, some people might not have enough of the key minerals and fat-soluble vitamins (which are vitamins
K, A, D, and E) that the body requires. However, a balanced diet should easily provide these and in the rare case when it doesn't, your doctor can prescribe a supplement.
There are two things you should avoid: alcohol and high-fat foods. For people with cirrhosis, regardless of the cause, alcohol should be completely avoided.
