Hi, thank you for asking Healthcare magic. I have gone through your query and understood your concerns. Initially, your problem was probably malabsorption resulting from indigestion of fat but now there is a possibility of an infection. I would suggest you wait for the laboratory results. But in the meantime, you can take acetaminophen (Tylenol) to control the fever. I hope that answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. We will be delighted to answer more questions from you. I wish you good health
