Hi, There can be many reasons for recurrent symptoms of food poisoning after taking treatment.1. The first reason can be that the medications and antibiotics did not clear the bacteria. This can happen because the bacteria are resistant, or the antibiotics were not taken for a duration long enough to cause elimination of infection.2. The second reason can be that there is still some contamination around in food or Chat Doctor. 3. The third can be due to severe form of infection like typhoid and this requires long duration treatment for 2 - 3 weeks.4. The symptoms of food poisoning might be potentiated by underlying irritable bowel disease.5. There can be an underlying surgical cause like diverticulitis that is causing the symptoms. An ultrasound scan or CT scan abdomen might be required for persistent symptoms.
