Viral gastroenteritis mostly lasts just less than a week and gets even better without having any medical treatment as referred by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Therefore, frequent diarrhea and vomiting might lead to excessive dehydration that is significantly dangerous in older adults and children. People having the symptoms of dehydration might look for medical attention.
Gastroenteritis might also be the reason for consuming contaminated food that can let harmful viruses, bacteria, or parasites to let them enter your body. The food poisoning symptoms are similar to those who are having viral gastroenteritis, and people must look to the doctor if they are experiencing dehydration or the symptoms might get worse.
