Duration of stomach flu depends on the severity of the attack. The condition may become worse in case of infants, young children and elderly who cannot drink sufficient fluids to compensate for dehydration experienced during the illness. For these people, stomach flu can last for 3 weeks or more.
The stomach flu is self-limited, meaning the symptoms usually end in 2-3 days, but can last up to 10 days. There is no cure, so focus on preventing it from spreading and making yourself as comfortable as possible while the virus runs its course. 2. Understand how the illness is spread.
