The dreaded ‘winter vomiting bug’ threatens to wreak havoc on the start of our festivities. There is currently no conventional treatment, [i] so read on to learn how nutrition and lifestyle may help you avoid infection, and support you during and after infection if it comes to that.
Norovirus is the infamous microbe responsible. The symptoms of winter vomiting bug include severe diarrhea and vomiting, and often fever, muscle aches, and weight loss too. Anyone can pick up this pesky bug, however young children, the elderly, and immunocompromised individuals are most vulnerable. [ii]
Symptoms usually only last 2-3 days, but norovirus can disrupt our health for several months, if not years, after the infection has cleared. It can trigger post-infectious irritable bowel syndrome (PI-IBS)[iii],[iv] and this is certainly what we observe in clinical practice.
