Answer:
Increase in the temperature of the body
Explanation:
Gastroenteritis or the stomach flu refers to infectious diarrhoea which causes inflammation in the stomach or the small intestine of the gastrointestinal tract of the digestive system.
The microbe responsible for the stomach flu could be a virus or a bacteria and the symptoms produced by the body are the vomiting, the abdominal cramps muscle pain and headache.
The disease could also result in mild fever which is caused by the increase in the temperature of the body as an adaptation to kill the invaded microbe.
Thus, Increase in the temperature of the body is correct.
