A new survey of nearly 7,000 people in the U.S. found that the number of people with Crohn, ulcerative colitis and ulcer cancer had all risen.
The study, published Thursday in the journal JAMA Internal Medicine, analyzed data from the Centers for Disease Control and Prevention’s National Health Interview Survey.
Researchers looked at people who had been diagnosed with at least one of the conditions in a previous year, as well as people who were diagnosed in the past year but not yet in remission.
Researchers also looked at how the people’s diet and health changed over time.
They found that in the previous five years, there was an overall increase in the number and type of people who developed Crohn disease, ulcers and ulcers, ulercolics and Crohn-related colitis.
The rate of Crohn and ulercoriasis increased from 15.1% to 17.1%.
The rate of ulcers increased from 9.6% to 10.5%.
Researchers also found that Crohn was on the increase in people who smoked cigarettes.
Those who smoked at least 10 cigarettes a day were twice as likely to have Crohn than people who didn’t smoke.
The CDC said that the rise in the Crohns and ulricias and ulterior colitis was the result of several factors, including the availability of antibiotics and the rising number of patients treated in the emergency room.
