question: Hi Doctor, i lost my daughter last month due to what the doctors said was hepatomegaly, why was her stool black in color?Could it be that her liver had a problem after she underwent Nephrectomy in December last year?Following some liver function tests done shortly before her demise it showed her Liver had stopped functioning long time ago, but she had never presented with jaundice, help me understand these as im stil trying to get into terms with the death f ma one and only daughter.
