How Common is Celiac Disease?
Celiac disease is an autoimmune disorder that primarily affects the small intestine when gluten is ingested. Its prevalence has been increasing globally, affecting approximately 1% of the population in many countries. However, estimates suggest that only about 20% of those affected are diagnosed, leading to a significant number of individuals who remain undiagnosed and may suffer from related health issues.
The frequency of celiac disease can vary by geographical region, ethnic backgrounds, and age groups. In areas with high-risk populations, such as those of Northern European descent, rates can be as high as 1 in 100 individuals. Conversely, in some parts of Asia and sub-Saharan Africa, prevalence rates are lower, around 0.1% or even less.
Moreover, celiac disease may present at any age, although it is often diagnosed in childhood or among adults in their 30s and 40s. Increased awareness and improved screening methods have contributed to higher reported rates as healthcare professionals become more attuned to the disease's symptoms and complications.
In summary, while celiac disease affects about 1% of the population, under-diagnosis remains a crucial issue, indicating that many cases may go unrecognized. Continued education and research are essential for better awareness, diagnosis, and management of this chronic autoimmune condition.
