Hi. Thanks for your query. Noted the history and understood the concerns. Gases and loose motions may not be related to putting in taking out implanon and since you are using preventive methods the pregnancy tests would definitely be negative. Hence the cause of gases and loose stools can be due to stress and is called as IBS that is irritable bowel syndrome. But this to say as IBS all the tests of blood, stool, ultrasonography and colonoscopy should be negative and hence should be done to rule out any pathology. If IBS then a proper stress control measures, avoidance of the foods and beverages that instigate or enhance the problems can be well controlled. Rarely you may need further specific and symptomatic management if needed. If any disease is found during the course of investigations then it should be treated appropriately.
