Acute gastroenteritis is primarily caused by unsanitary eating habits or exposure to cold, spicy, and other irritants, leading to acute inflammation. The main symptoms include abdominal pain, diarrhea, nausea, vomiting, or fever, and a routine blood test may show elevated white blood cells and neutrophils. If these symptoms appear, it is advisable to visit a hospital promptly for a routine blood test. Once a diagnosis is confirmed, doctors will treat with anti-inflammatory fluids, antiemetics, antidiarrheals, etc. Generally, mild acute gastroenteritis can be cured within two to three days of treatment. However, some patients may experience severe vomiting and diarrhea, leading to dehydration, electrolyte disorders, and even shock, which would extend the required treatment duration.
