Why do you get 'stomachache' in your lower abdomen when your stomach is much higher up in the body?

* Constipation is one of the most common reasons for abdominal pain. If you haven't had a bowel movement (poop) for a while or if it hurts to go to the bathroom or your bowel movements are hard, you are probably constipated. * Diarrhea is often caused by an infection that some people call "the stomach flu." Doctors call this type of diarrhea/infection gastroenteritis. When you have diarrhea - runny, watery bowel movements - you may also feel sick to your stomach. * Vomiting. Feeling sick to your stomach and throwing up can also be linked to gastroenteritis. The pain is one way your body tells you to stay near a bathroom! * An infection someplace else in your body may cause belly pain, too. A sore throat, pneumonia, an ear infection, or a cough can sometimes cause tummy trouble as well. * Food. Some kids get abdominal pain because they ate too much of something, ate a food that was too spicy or greasy, ate a food they have an allergy to, or ate food that sat around in the fridge for too long and went bad. The pain is the body's way of telling you that your stomach and intestines are having a tough job breaking down or digesting this food. For example, some people have lactose intolerance, which means they have a tough time digesting lactose, a type of sugar found in milk and other dairy foods. Whatever the cause, funky foods can quickly make your tummy feel funky! * Appendicitis or other painful problems. If the pain starts by your belly button and then moves to the lower right side of your abdomen, it might be appendicitis. Fever or vomiting, along with pain that gets worse and worse and a loss of appetite, can also be signs of appendicitis. * Severe pain also can be caused by a urinary tract infection or a blocked intestine. Infection by bacteria or a parasite, heartburn, irritable bowel disease, or inflammatory bowel disease also can cause abdominal pain. * Stress. Many, many kids (and adults, too) have a "nervous stomach" when they are worried or stressed.
