The gastrointestinal system or, as it’s sometimes called, the "GI system," is the body’s plumbing system. It allows people to eat food, digest and absorb energy from the food and expel waste. In humans, it is made up of the mouth, esophagus (the tube that food travels down to meet the stomach), the stomach, the small intestine (where nutrients are absorbed and passed to the bloodstream) and the large intestine (where excess water is removed). The large intestine also includes the appendix. The pancreas and spleen are also considered part of the GI system.

Some symptoms you might be experiencing if you are having gastrointestinal problems include:

  • Blood in your stools 
  • Constipation 
  • Diarrhea 
  • Severe cramping and indigestion 
  • Vomiting

the right screening

right now

The recent untimely death of actor Chadwick Boseman has put the spotlight on the importance of not delaying colon cancer screenings. Dr. Ergen Muso shares his knowledge of at-home tests and colonoscopies—the “gold standard” test. 

Don't Delay

Important Screenings

“It can be confusing to know what is best and safe after months of stay at home orders,” says CMC gastroenterologist, Dr. Hatem Shoukeir. “However, colorectal cancer screenings are essential to keep you healthy. In fact, delaying them due to fears of contracting COVID-19 can actually cause more harm than good. Colon cancer is highly treatable, especially when caught early.” Call CMC’s NH Gastroenterology to schedule an appointment:

Tests to identify GI issues

Your CMC gastroenterologist may perform tests to determine what part of your gastrointestinal system is malfunctioning. These may include various types of imaging including endoscopy, colonoscopy, sigmoidoscopy or biopsies. They may perform abdominal X-rays for issues of the lower GI tract. In some cases, your GI problem may be treated with medication or it may require surgery to return you to full functioning. Our experts will diagnose and treat you with the care you deserve.
