Weight loss, vomiting and diarrhea are very vague signs and common to many conditions - parasitic, bacterial and viral gastroenteritis, inflammatory bowel disease, liver and kidney disease can all cause the symptoms you describe. I strongly recommend a full blood panel in order to investigate internal causes as the weight loss is progressive and would suggest that there may be additional complicating factors present. Semi-solid and liquid foods such as freshly boiled chicken and rice can be easier to digest than dry or solid foods and may help the bowel to readjust, I would also consider adding a probiotic such as fortiflora in the meantime as this may help with bowel recovery following the bloodied diarrhea
