What Causes Abdominal Cramps, Blood In Stool And Vomiting After Eating Food?

food-borne gastroenteritis
Detailed Answer:
Hello,
it seems that you've had a food-borne gastroenteritis. Vomiting suggests the presence of preformed toxin. The stool culture will be more helpful probably although in many cases no pathogen can be detected. If you've had fever then antibiotic treatment might be necessary. Without fever and if you're getting better then you can wait without antibiotic treatment.
Regarding the blood, it depends on its origin. If its from irritated hemorrhoids, which may bleed after repeated bowel movements, then there are no serious worries, unless the bleeding is severe. If it's blood homogeneously mixed with the stool then it could originate from the inflammed intestine due to the gastroenteritis. Gastroenteritis with bleeding usually denotes more serious disease. When combined with fever it's even more serious.
Make sure you drink enough fluids and visit your doctor if vomiting and diarrheas prevent you from hydrating yourself. Regarding food intake, you should try to avoid fiber, fat and milk because they may worsen diarrhea. Prefer carbohydrates and protein (rice with chicken for example).
Best wishes for a speedy recovery!
