Fatigue
Many people with stomach flu often have a lack of overall energy or a sensation of tiredness. Unlike normal exhaustion, this condition will not go away even when you rest or sleep. Indeed, it might persist for days or even weeks until it disappears itself. The main reason why you experience this symptom is that your body has to spend a lot of energy on fighting harmful viruses and bacteria which are causing the flu. The best way to deal with gastroenteritis-related fatigue is to contact your healthcare provider for medical advice. [5]
