Food is a common cause. For example, eating too much junk food or food that has gone bad can lead to a belly ache.
I knew a boy who had a belly ache because he ate some expired snacks. He started feeling pain in his belly not long after. His parents rushed him to the hospital where he was given medicine to relieve the pain and help with his digestion.
Maybe he ate too much junk food.
Poor diet is a very common cause. Eating too many processed foods, high in fat and sugar, can lead to a big belly. For example, those who consume a lot of fried foods regularly are likely to gain belly fat.
He might have taken some medicine.
If the pain is due to indigestion, lying down on her side in a comfortable position and taking it easy for a while can be beneficial. Avoiding any strenuous activity gives the stomach time to settle. Also, over - the - counter antacids can be used if the pain is caused by excess stomach acid, but it's best to consult a doctor or pharmacist first.
One common cause is a delay in the development of bladder control. Young boys' bladders may not be fully developed to hold urine throughout the night. Another cause can be stress. For example, if there are changes at home like a new baby or moving to a new place, it can trigger bedwetting. Also, some medical conditions such as urinary tract infections might lead to it.
I'm not entirely sure specifically what a 'belly ache fanfic' is about as it could be very unique to the creator. It might be a fan - created story that somehow involves the concept of a belly ache, perhaps in a humorous or dramatic way within the context of a particular fandom.
In some fanfics, a character might get a stomach ache due to eating something strange in a magical world. For example, in a fantasy fanfic, a character eats a glowing fruit not meant for humans and gets a severe stomach ache. Remedies could be a special potion made by a local healer.
Food poisoning can be a reason. Just like if a woman eats something rotten or contaminated, it can lead to a bad belly ache.
One possible reason could be indigestion. If a girl eats too much junk food or something that doesn't agree with her stomach, it can cause pain. For example, consuming a large amount of spicy food might irritate the stomach lining.
