The short explanation
It could be. Dizziness and breathlessness on stairs along with heavy periods are typical signs of anaemia, where the blood has too little haemoglobin to carry oxygen well. Heavy menstrual bleeding is one of the most common causes of iron-deficiency anaemia in women in India. It develops slowly, so many women get used to feeling tired and do not realise how low their levels are. A simple blood test can check your haemoglobin and iron. If anaemia is found, a clinician may suggest treatment to restore iron, and it is equally important to find out why your periods are heavy, so the cause can be treated too.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Other signs of anaemia include pale skin, a racing heart, headaches, brittle nails and feeling cold.
- Iron-rich foods such as green leafy vegetables, lentils, jaggery and meat or fish if you eat them help, but food alone may not be enough when bleeding is heavy.
- Blood tests and treatment are available at PHCs and government hospitals at low cost.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether you have anaemia or why your periods are heavy. A blood test and examination are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Can you check my haemoglobin and iron levels?
