Adverse effect

Okay kiddo, so an adverse effect is something that happens when we take some kind of medicine or eat some kind of food that our body doesn't like. It can make us feel really yucky, like we might get a headache or stomach ache or feel really tired.

You know how your body has a lot of different parts that all work together? Well, sometimes when we take medicine or eat food, it can mess with how those parts work. For example, if we take too much medicine or medicine that our body doesn't like, it can make our heart beat too fast or too slow or it can make it hard to breathe.

Adverse effects can happen to anyone, even adults, and doctors and scientists are always testing and studying medicines and foods to make sure they don't have too many adverse effects. They want to make sure that everything we eat or take makes us feel good and healthy.
