Hi. Thanks for your query... This is a severe form of your problem ans you should visit the ER sooner. The probable causes are infection of intestines or some part of abdomen. You need to be seen by a Doctor to examine clinically for the vitals like temperature, pulse, respiration, blood pressure. If the vitals are disturbed you need to be admitted , investigated and treated accordingly. Initially you need tests of blood to see the level of infection,blood sugar, kidney and liver function tests; urine , stool tests and most important standing X-ray abdomen and ultrasonography. Visit the ER ASAP, do not try anything at home, do not take solid foods as empty stomach or only liquids are necessary for investigations.
