The flu is different from the stomach bug in the sense that the flu may affect the respiratory system of the body while the stomach bug will affect the digestive system. The virus that causes these two different conditions are different from each other. The symptoms that you will experience when you are suffering from both are also highly different from each other.
Flu is considered to be more serious especially if it would not be immediately medicated. There are some people who only start with flu but after some time, they will start to suffer from bronchitis or even pneumonia. It is best to get yourself checked by a medical professional so that you can get the necessary treatments that your body needs.
You may think that the flu and the stomach bug are the same, but it would only be somewhat similar if you would use stomach flu and a stomach bug. Stomach flu means that your stomach is not feeling well. You may think that your stomach is acting up. There are instances when you will not be able to keep anything down.
When you feel this way, you need to figure out what has caused your stomach flu. It might be something that you have eaten, or it might also be because of your condition. A stomach bug is a condition that will make you feel that your stomach is not working or digesting as well as it should.
