Patients with acute gastroenteritis experience rapid onset of symptoms but can recover quickly with proper and standard treatment after diagnosis. Acute gastroenteritis generally involves simultaneous infection of the intestinal and gastric mucosa by bacteria or viruses. With appropriate treatment, using anti-inflammatory medications or probiotics, the disease can be rapidly resolved without any problems, typically healing within two to three days. Therefore, when suffering from acute gastroenteritis, it is important to rest, preferably by staying in bed without engaging in strenuous activities to avoid exacerbating the condition. Usually, taking two to three days off from work is completely sufficient.
