What could be the possible reasons for a furry girl having diarrhea in a fanfic?

It could be due to a viral or bacterial infection. In a fanfic setting, perhaps she caught a bug from someone else in her fictional world. For instance, if she was in a crowded place like a concert or a busy market and came into contact with someone who was sick, she could get an infection that causes diarrhea.

There could be many reasons. Maybe she ate some contaminated food like unwashed fruits or spoiled dairy products. Another possibility is that she has a food intolerance, for example, lactose intolerance if she consumed dairy. It could also be due to a virus or bacteria she caught, like the norovirus which is quite common and can cause diarrhea.

She could find some special herbs. In many fanfics, there are often magical or medicinal herbs that can cure various ailments. So she might search for and consume a herb known for its digestive - regulating properties.

Food poisoning is a common reason. For example, if she ate expired food or food contaminated with bacteria.

A girl may have a pale white stomach if she is constantly stressed. Stress can affect the body's hormonal balance and blood flow, which may lead to paler skin. Also, if she has a genetic predisposition to having fair skin in that area, it will be pale white. Moreover, if she recently recovered from an illness, especially one that affected her digestive system, her stomach might look paler as the body is still in the process of fully recovering and getting back to normal blood flow and pigmentation in that area.

There are several possible reasons. Firstly, emotional factors can play a role. If she is going through a period of stress or sadness, she might overeat. Secondly, a new hobby related to food, like cooking and then eating the results. Thirdly, a change in her daily routine. For instance, if she used to be very active during the day but then starts sleeping more and moving less. In a furry girl weight gain story, these factors can combine to cause her to gain weight.

Maybe she caught a cold. In many fanfics, characters get fevers because they were out in the rain or caught a virus from someone else.

This is a rather unseemly topic, but one could imagine a situation where a cheerleader ate something bad right before a big game or performance. Maybe she had some spoiled food from a concession stand and her stomach started acting up suddenly during the routine, leading to an embarrassing situation with her pants.

One reason could be that she is carrying something in her pocket like a phone, a small wallet or keys which create a bulge. For example, if she has a large and bulky phone case, it can be quite noticeable.

Another reason might be as a form of punishment or lesson. Athena, being the goddess of wisdom, could be teaching Percy something about seeing the world from a different perspective. By turning him into a girl, he might gain new insights into how females are treated in the world of the story, whether it's in the demigod community or among mortals.
