The short explanation
It can, in two different ways. Some anaemias are truly inherited, such as thalassemia trait or sickle cell trait, which are passed down through genes and are more common in certain communities in India. In these, red cells are small or shaped differently from birth, and iron does not correct them. More often, though, family members share habits and circumstances rather than genes: similar vegetarian diets, tea with meals, heavy periods that also run in families, or the custom of women eating last. A simple set of tests can tell these possibilities apart.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- A complete blood count showing the size of red cells, iron studies, and a haemoglobin test called HPLC can help separate iron deficiency from an inherited trait.
- Knowing about an inherited trait matters before pregnancy, because if both partners carry certain traits there is a risk for the baby.
- If you have been taking iron for years without improvement, an inherited cause becomes more worth looking for.
- A family pattern is also a reason to be screened before pregnancy and to tell any doctor who prescribes iron that relatives have similar results.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether your family's anaemia is inherited. Blood tests on you, and sometimes other family members, are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Should I be tested for thalassemia or sickle cell trait?
- Is my anaemia from iron deficiency, an inherited trait, or both?
- Should my sister and mother get the same tests?
- What does this mean if I plan a pregnancy?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a doctor within a few days if you feel breathless on climbing stairs, dizzy, or your periods have become heavier.
Raise it at a routine appointment
- Book a routine appointment to ask for tests that look for inherited anaemia as well as iron levels.
- Encourage your mother and sister to get checked too.
