Celiac disease exists in both Africa and Asia, although the prevalence and awareness of the disease can vary greatly between different regions and countries on these continents. Celiac disease is an autoimmune disease that can affect genetically predisposed individuals anywhere in the world, regardless of race or ethnicity. However, there are several factors that influence the perception and recognition of celiac disease in Africa and Asia:
The genetic predisposition to celiac disease is mainly linked to the presence of the HLA-DQ2 and HLA-DQ8 alleles. Although these genetic variants are more common in some European populations, they are also present in several populations in other parts of the world, including some groups in Africa and Asia. This means that even in these regions there is a genetic basis for the development of celiac disease.
Diet and Lifestyles
Differences in diet between various cultures can influence the prevalence of celiac disease. Traditionally, many Asian and African cultures rely less on wheat and more on other grains such as rice, corn or sorghum, which do not contain gluten. However, with globalization and the adoption of Westernized diets, the consumption of gluten-containing foods is increasing in these regions, potentially leading to an increase in cases of celiac disease.
Awareness and Diagnosis
In many parts of Africa and Asia, awareness of celiac disease is still limited, both among the public and health professionals. This can lead to significant underreporting of celiac disease cases, with many individuals going undiagnosed or receiving a late diagnosis. Lack of knowledge and resources for the diagnosis and treatment of celiac disease may prevent the identification of cases in these regions.
Studies and Research
There have been fewer studies on the prevalence of celiac disease in Africa and Asia than in Europe and North America. However, available studies indicate that celiac disease exists in these regions, although it may be less common or less recognized. Continued research is critical to better understand the global distribution of celiac disease and its manifestations in different populations.
In conclusion, celiac disease is a global condition that knows no geographical boundaries. Although prevalence may vary, it is important to increase awareness and improve diagnostic capabilities around the world, including in African and Asian countries, to ensure that people with celiac disease can be correctly diagnosed and treated.
