###Human: Will antibiotics help to improve IBS? ###Assistant: Hi. I have gone through your query and reports (attachment removed to protect patient identity). I can understand your concern. As you told that your mother had IBS (irritable bowel syndrome), I want to tell you that antibiotics are not the treatment for IBS. Probiotics can help. She might have developed antibiotic induced diarrhea after taking tablet Flagyl (Metronidazole). I have seen her reports and they seem to be normal except ultrasound which is difficult to interpret as it is not clear.  No need to worry she might have developed malabsorption syndrome because of chronic diarrhea as she cannot tolerate lactose containing food. There is no need to give excess vitamin B12 unless there is deficiency. Your mother needs proper evaluation and blood transfusion is not required. Get her serum vitamin B12, folate, serum calcium, vitamin D, stool routine and occult blood checked. Consult a gastroenterologist. As she had chronic diarrhea she needs colonoscopy also.
