Hi and Welcome to Healthcare Magic... Having bowel movements immediately after taking food along with abdominal cramps / pain can be due to many causes. I would first like to know if this is an acute or a chronic problem because the causes would vary accordingly. If it has been acute and only for a few days, it could be due to a gastro-intestinal infection, particularly a parasitic infection such as giardiasis. Sometimes an infection of the reproductive tract can also irritate the bowel and cause such symptoms. If it has been a chronic problem, it is likely to be an Irritable Bowel Syndrome (IBS), where the predominant symptoms are chronic abdominal pain or discomfort or cramping and frequent bowel irregularities. So, if it has been an acute problem, I would suggest consulting a general practitioner and if needed, getting a few tests done such as stool, urine tests. If it turns out to be an infection, then you may have to take a course of antibiotics. If it has been a chronic problem and if your basic investigations are normal, then you can consider the folowing advise: 1) Try dietary adjustments such as increasing the fibre content in your diet, avoiding foods that stimulate your intestines like spicy foods, coffee, tea, carbonated drinks, etc. (Smoking can also be an irritant) 2) Try to have a healthy lifestyle with regular exercise and proper sleep habits. 3) Try to avoid stress and try relaxation methods like deep breathing, meditation, etc. 4) Sometimes, certain medication can help (anti-spasmodics, anti-anxiety medication, etc.) - it s better to consult a doctor for this rather than trying over-the-counter-medication. I am not clear what your concern is regarding taking an emergency contraceptive pill. Have you been getting your periods after taking the pill? Please clarify... If you have any further doubts / clarifications, please feel free to ask me... Hope you get well soon. Regards, Dr. Jonas Sundarakumar
