Nausea, Trouble With Digestion And Swollen Abdomen. What Could This Be?

Hi, For now a couple of months, I haven t feel well. I almost always feel nausea, I have trouble with my digestion, sometimes during short episodes I feel bad and throw up after a meal. A lot of acidity in my stomach, often I have swollen abdomen. Diarhea or pale loose stools are my daly routine, sometime with mucus. I have bad breath and bad body odor even if I have a perfect hygien routine, two showers a day, brushes teeth twice a day... I do everything I can, but it seems not enough. My sweat smell so bad, like ammonia or cat pee. My urin is dark and smells funny too. Most of the people around me notices I smell bad, even short after a shower. Some say i smell like fart, cat pee, like smelly feet. I had trouble with my liver a couple years ago. My enzymes were so high, I coudn t eat, always throwing up. I had yellow skin and eyes. They said I had some kind of liver disease. All I could do was take a three months break to recover. I don t know if this can be related, but with what I read on the net it might be. But what could I have?? What are the diseases that causes bad smells like mines?
