I feel tired and breathless all the time. Could it be anaemia?

An AskHer answer: what is known, what depends on you, and what only a clinician can decide.

Nobody asked this one. AskHer’s editorial team wrote the question to open the topic. It is not anyone’s submission, and nobody’s own words are in it.

The short explanation

It could be, and it is worth a simple blood test to find out. Anaemia means you have fewer red blood cells or less haemoglobin than usual, so less oxygen reaches the body. Common signs are tiredness, breathlessness on stairs, a racing heart, headaches, looking pale, feeling cold, and brittle nails or hair fall. Anaemia is very common in Indian women, most often from low iron, but it is not the only cause of tiredness, and a test is better than guessing.

What depends on your situation

The parts of this that change from woman to woman. Uncertainty is stated, not hidden.

  • Heavy periods, pregnancy, closely spaced pregnancies, a diet low in iron, and worm infections are common reasons for low iron. Less often, anaemia comes from low vitamin B12 or folate, from bleeding in the gut, or from inherited conditions such as thalassaemia trait, which is common in parts of India and does not respond to iron.
  • Tiredness can also come from thyroid problems, poor sleep, depression or diabetes, so a clinician may check more than one thing.

What this answer cannot determine

The boundary of online education. These need a clinician who can see you.

  • This cannot tell you whether you are anaemic or why. A blood count, and often iron studies, are needed, and the cause decides the treatment.

Questions for your clinician

Take these with you. You can add any of them to an appointment card.

  1. Could my tiredness be anaemia, and which blood tests would show it?
  2. If I am anaemic, what is the likely cause?
  3. Should my thyroid or vitamin B12 be checked as well?
  4. Should I be tested for thalassaemia trait?

When to seek help

Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.

  • Get emergency care now (call 112 or 108) for chest pain, severe breathlessness at rest, fainting, or black tarry stools or vomiting blood.
  • See a clinician within days for tiredness with very heavy periods, breathlessness on mild effort, or a racing heart.
