An Overview of Common GI Tract Issues in the US

Gastrointestinal (GI) tract issues rank among the most common health problems in the United States. A study by the American Gastroenterological Association found that between 60 and 70 million Americans live with one or more GI diseases, which can seriously impact overall health and wellness. In 2018, the National Institutes of Health reported that two out of three Americans experienced GI symptoms at any given time.

The GI tract is a key component of the human digestive system. Specific diseases and symptoms may impact the tract, which moves food throughout the body, or other parts of the digestive system, such as the liver, pancreas, and gallbladder. Gallstones, for instance, impact upwards of 25 million Americans, nearly 75 percent of whom are women. A gallstone is a solid lump that forms in the gallbladder as bile crystallizes. The stones vary in size from grains of sand to the size of a golf ball. Initial symptoms include sharp, stabbing pain in the abdomen, which, over time, can cause nausea and vomiting. Without medical or surgical intervention, gallstones can develop into more serious digestive problems, such as pancreatitis.

Gastroesophageal reflux disease (GERD) and gastroesophageal reflux (GER), also known as acid reflux, represent an even more common GI issue for Americans, impacting between 20 and 33 percent of the population. Many Americans experience GER following a large meal or after drinking too much coffee, while GERD involves reflux symptoms occurring at least twice per week. Often, individuals can minimize the discomforting symptoms via lifestyle changes, but advanced cases of GERD may demand medication or one of several surgical procedures.

Irritable bowel syndrome (IBS) is another common GI issue, impacting 10 percent of people in the United States every year. IBS symptoms include abdominal pain, bloating, constipation, and changes in bowel movements. Symptoms often impact a person’s ability to go about their daily lives, though a combination of medication, probiotics, medical nutrition, and mental health therapies can mitigate symptoms.

A combined 3 million Americans live with ulcerative colitis or Crohn’s disease, two painful inflammatory GI diseases. Ulcerative colitis involves inflammation of the large intestine, resulting in sores along the intestinal lining. The sores cause abdominal pain, as well as the repeated urgent need to have bowel movements. A chronic disease, ulcerative colitis may last for years without dissipating, and researchers have yet to develop a cure, though dietary changes and certain medicines can reduce symptoms.

Similarly, Crohn’s disease impacts the body with severe and chronic inflammation. However, inflammation is not limited to the large intestine and can spread throughout the GI tract, all the way from the mouth to the anus. Crohn’s is an especially painful disease, with additional symptoms including frequent diarrhea, cramping, and severe weight loss. Individuals living with Crohn’s disease must take medication and practice various physical therapies.

Peptic ulcers can also cause abdominal pain. These open sores form along the lining of the stomach and the top of the small intestine due to bacterial strains that weaken the GI tract’s protective outer layer and allow stomach acid to directly contact various tissues. Most treatment plans involve a regimen of antibiotics.

Finally, hemorrhoids impact close to 50 percent of Americans aged 50 and older. A hemorrhoid is a blood vessel in the rectum or anus that swells, causing severe itching and pain. Risk factors for hemorrhoids include chronic constipation and diarrhea, meaning they often accompany other GI issues, while treatment plans typically consist of stool softeners and refraining from straining the impacted area.
