Fever
With stomach flu, your body will have different responses. One of them is to increase the interior temperature, thus leading to a fever. While many people often consider this as a negative effect, a fever during stomach flu can actually be an effective way of eliminating the virus or bacteria causing the issue. However, if your fever exceeds 102 degrees and lasts more than 5 days, it is extremely important to visit your doctors because it can be a severe case. Also, you might experience chills during this condition, which happen when there are changes in your body temperatures. [4]
