Hi, my mom just undergone open surgery for appendicitis and after that she is taking metronidazole she feels always like vomiting and lose her appetite is it normal after surgery until when? Now she is still waiting for the biopsy. Her stool also is a lil bit watery is it only side effect of the antibiotics? What to expect after appendix removal to a patient with diabetes also? What are the dos and do nots of eating? Thank you.
