In most cases, intestinal flu, also referred to as gastroenteritis, resolves on its own within 10 days, explains WebMD. It is important for individuals with gastroenteritis to increase fluid intake while recovering to prevent dehydration caused by vomiting and diarrhea. Individuals should avoid milk and acidic juices, as these beverages may exacerbate symptoms.
It is important for individuals infected with gastroenteritis to seek medical attention if vomiting persists for more than 48 hours or if vomit contains blood, explains Mayo Clinic. Additional symptoms that may indicate a medical emergency include bloody stools, high fever and the inability to hold down fluids for 24 hours. Sufferers should also consult with a physician if they experience symptoms of dehydration, such as dark yellow urine, decreased urination, dry mouth and vertigo.
