Diseases of the digestive system can present in a variety of ways, depending on the location of the problem within the gastrointestinal tract, the severity and duration of the problem, and the sensitivity of the organs to potentially painful changes within the tract.
It is true that many people occasionally experience a bout of diarrhea
or stomach pains, but only a doctor
can help you determine if your symptoms are "run-of-the-mill" or warrant further investigation. A thorough history can be performed, looking for signs that are often labeled as "red flags." These symptoms include weight loss, bloody bowel movements, dark black tarry bowel movements, anemia
, fever, vomiting, and chronic or significant abdominal pain that is not relieved by bowel movements. These symptoms should raise concern for an underlying process that may endanger your health and need further work-up by your physician.
Following a thorough history and physical exam, your physician may choose to perform further testing with blood work (for example, testing for anemia and thyroid dysfunction) or may choose to do an imaging study (ultrasound) or procedure (such as a colonoscopy) to gain further information to make an accurate diagnosis.
