Gastroenteritis can be classified as bacterial gastroenteritis, and viral gastroenteritis is depending upon the infectious micro-organism (bacteria, virus) causing it. Bacteria causing gastroenteritis include Shigella, Campylobacter, Salmonella, Clostridium, Escherichia coli, and Staphylococcus, etc. While the viruses that boost in spreading infectious intestinal disease are rotavirus, norovirus, sapovirus, adenovirus, and astrovirus.
Viruses and bacteria easily spread through water and food and infect the gastro tract. Also if a person doesn’t follow good personal hygiene, then the virus or bacteria can spread from their own hands. Bacteria and virus that cause food poisoning and diarrhea are also responsible for causing gastroenteritis in several people. Viruses like the norovirus and the rotavirus spread to humans from water, dairy products, raw vegetables, and uncooked food. Bacteria are responsible for gastroenteritis and spread to a human in the same way as the viruses.
The classic symptoms of gastroenteritis begin with severe abdomen pain usually. It’s not a constant pain, but it’s more like cramps which come and frequently go in a rhythmic fashion. It may be an excessive pain. Nausea and vomiting is another sign as the body stops accepting any more food until the bacteria or virus is cleared out. Headaches are another symptom that is caused due to the dehydrating effect of the disease. Diarrhea is also a primary symptom and due to excessive diarrhea dehydration is also caused. The person may be going to the bathroom to pass motion more than three to four times in an hour and also are constantly thirsty.
However, gastroenteritis is diagnosed only after a blood and stool test and is determined based on which bacteria or virus was found.
