Inflammatory bowel disease more prevalent than previously thought

More than three times as many American adults have been diagnosed with Crohn’s disease or ulcerative colitis than was believed, a new analysis has found.

The diseases, both classified as types of inflammatory bowel disease, or IBD, contribute to a diminished quality of life and costly medical complications, said analysts at the U.S. Centers for Disease Control and Prevention.

Investigators reviewed data from the 2015 National Health Interview Survey and found that an estimated 3.1 million U.S. adults, or about 1.3 percent of all U.S. adults, had been diagnosed at some point with IBD.

The finding that inflammatory bowel disease is more prevalent than health officials had realized “is important to understanding the burden this disease currently places on the U.S. health care system,” researchers wrote. “Highlighting population subgroups with higher prevalence rates of inflammatory bowel disease can enable a better understanding of the disease and the populations most affected.”

Another recent study found links between Crohn’s disease and an increased risk for thyroid cancer.

What is inflammatory bowel disease?

Crohn’s disease and ulcerative colitis are both chronic inflammatory conditions of the gastrointestinal tract. Ulcerative colitis affects only the colon; Crohn’s may affect any part of the GI tract, from the mouth down.

Symptoms may include:

  • Persistent diarrhea
  • Rectal bleeding
  • Frequent urge to move bowels
  • Fever
  • Loss of appetite followed by weight loss
  • Fatigue
  • Abdominal cramping

Health care providers often treat the symptoms of the diseases with medication, but most Crohn’s sufferers will eventually require surgery, according to the CDC.

The statistics about the prevalence of inflammatory bowel disease, “Prevalence of Inflammatory Bowel Disease Among Adults Aged ≥18 Years — United States, 2015,” were reported in the CDC’s Morbidity and Mortality Weekly Report this fall.

The study linking Crohn’s disease and thyroid cancer was published in the journal Inflammatory Bowel Diseases, the journal of the Crohn’s & Colitis Foundation of America Inc.
