Anaemia check
Anaemia is very common in India
Anaemia affects many women, children and older adults in India. It is easy to test and usually easy to treat once the cause is known.
Who should have a blood count
Ask for a blood count if any of these apply:
- !Women with heavy periods or who are pregnant.
- !Children with poor appetite or poor growth.
- !Tiredness or breathlessness that is new.
- !A family history of thalassaemia — especially before marriage or pregnancy.
Blood care at Charak
- Consultations with Dr. B. K. Singh, Haematologist.
- Blood bank and transfusion support on the same campus.
- Cancer care with the oncology team.
Iron-rich habits
Tap each one you do:
- I eat green leafy vegetables, pulses and jaggery
- I eat eggs, meat or fish if I am non-vegetarian
- I take vitamin C-rich fruit with meals
- I avoid tea or coffee with meals
- I take iron tablets as prescribed
- I have treated worms, if advised
- I had a blood count this year
Thalassaemia carrier testing before marriage or pregnancy can prevent thalassaemia major in children.

FAQs
Frequently asked questions
Why is my haemoglobin low?
The most common cause is iron deficiency, but there are others, such as vitamin deficiency, blood loss or bone marrow problems. Tests find the cause.
Is a bone marrow test painful?
It is done under local anaesthesia. Most people feel pressure and brief discomfort.
Can thalassaemia be prevented?
Carrier testing before marriage or pregnancy helps couples know their risk and plan.
Is leukaemia curable?
Some types of leukaemia can be cured, and many can be controlled with treatment. It depends on the type.
Do I need IV iron?
IV iron is used when tablets do not work, are not tolerated, or anaemia needs faster correction.
Is blood available for transfusion?
The hospital has a blood bank. Donors from the family help keep the supply available.
Is bone marrow transplant available?
Bone marrow transplant is not done at Charak Hospital. If it may help you, our haematologists will explain the options, guide you on referral to a transplant centre and continue your care before and after.
