Celiac disease more common among Americans with Punjabi ancestry, study shows

About 1.8 million Americans have celiac disease, an immune-based condition brought on by the consumption of gluten in genetically susceptible patients. Among patients diagnosed with celiac disease by small intestinal biopsy in the U.S., those from the Punjab region of India have the highest rates of disease, according to new research published in Clinical Gastroenterology and Hepatology,1 the official clinical practice journal of the American Gastroenterological Association.

"While celiac disease was previously thought to be a disease predominantly affecting Caucasian Europeans, it is now recognized as one of the most common hereditary disorders worldwide," said study author Benjamin Lebwohl, MD, Herbert Irving Assistant Professor of Medicine and Epidemiology at the Celiac Disease Center at Columbia University Medical Center, New York, NY. "Our findings help shed light on the distribution of celiac disease in the U.S. and will aid gastroenterologists in diagnosing their patients."

This research gives insights into celiac disease found in the U.S. Among patients who underwent testing for celiac disease:

  • Celiac disease was most common among Americans from the Punjab region of India.
  • Celiac disease was significantly less common among U.S. residents of South Indian, East Asian and Hispanic ancestry.
  • The rate of celiac disease among patients of Jewish and Middle Eastern ethnicities was similar to that of other Americans.
  • Men and women had similar rates of celiac disease when tested, no matter their ethnicity.

"While previous studies have suggested that celiac disease may be more common in female patients, based on our findings we recommend that physicians consider celiac disease in men as often as they consider it in women," added Dr. Lebwohl.

When a patient is having signs of celiac disease, a doctor will do a biopsy in which several small pieces of tissue are sampled from the small intestine for examination with a microscope. The doctor is looking for villous atrophy, or damage to the wall of the small intestine, a finding which most often represents celiac disease.

    I don't know about the Punjab a region of India but in the USA people daily lifestyle and feeding system is a root of Celiac disease. I am not saying people should not eat delicious foods but wants to say that they all should follow the diet and other medical procedure that will make their health in good. Also, when they get disease should try natural remedy or medicine like "Lean N Clean®" first with experts approval.
