Lower Abdominal Pain
The lower abdomen on the left side has the sigmoid colon as it comes down and bends. This is a favorite location for larger parasites to settle permanently. Flukes, roundworms, parasites of all kinds and their attendant bacteria and viruses can be felt if they produce gas and pain. Sometimes they live perfectly quietly, seemingly in harmony with us.
Moving the bowel more frequently expels them repeatedly and prevents their numbers from getting very high. Nature may help you with this by setting up diarrhea.
Diarrhea is your clue that intestinal freeloaders are present.
The small intestine leads into the colon at your lower abdomen on the right side. At the junction is the ileocaecal valve that prevents backwash, and the appendix. The ascending colon goes up your right side then becomes the transverse colon that crosses your abdomen at the belly button level. The colon descends on your left side, leading into the sigmoid.
E. coli and Salmonella and Shigella are "enteric" (they live in your bowel) bacteria that can give you severe abdominal distress and pain. In fact, you can become a chronic sufferer. They can live on hands and under your fingernails, so reinfection from yourself is the most important source. Never, never touch your fingers to your lips. Most importantly, don't try to stop your frequent bowel movements. They will stop on a dime when your parasites and bacteria are dead and gone.
Other sources of E. coli are personal water bottles, other people's hands, hands that have changed baby diapers or cleaned bathrooms.
Hands do everything. To eliminate their threat of reinfection, cut out the section on hands and paste it on your refrigerator.
