11 Silent Health Risks Common in South Asian Genetics

10. Carrier States and Hereditary Blood Disorders (e.g., Thalassemia Trait) — What You Need to Know

Certain hereditary blood disorders, like thalassemia traits, are more common in parts of South Asia. Carriers often feel healthy and show minimal signs, but when two carriers have a child, the child can inherit a serious condition. That makes preconception or early pregnancy carrier screening very valuable for family planning. Simple blood tests and hemoglobin electrophoresis detect carrier states. Discuss carrier screening with your primary care doctor or obstetrician if you or your partner trace ancestry to South Asia. Genetic counseling helps families understand options and next steps. In many communities, organized screening programs and awareness campaigns have reduced the number of affected births. Bringing this topic into family conversations before pregnancy is a practical, compassionate step that avoids surprises later.
