Wiped out during your period? Iron deficiency is often the reason

Feeling exhausted every month during your period is not a personality trait. If you consistently need naps, feel breathless climbing stairs, or lose steam by lunchtime — especially in period week — iron deficiency is one of the most common (and most under-diagnosed) reasons in women.

The scale of the problem

The World Health Organization estimates that 30–50% of women of reproductive age in India are anaemic. Heavy or long periods are the leading cause. The tricky part: iron levels can be low before you become fully anaemic — and you feel tired the whole time without knowing why.

Two blood values to know

• Haemoglobin (Hb) — how much oxygen-carrying protein your blood has. Low = anaemia. Normal for women is ~12 g/dL and up.
• Ferritin — your iron storage level. This drops first, well before Hb falls. If ferritin is under 30 ng/mL you're depleted. Many women need it above 50 to feel well.

Ask your doctor for both. Testing only Hb misses early iron depletion.

Symptoms — how iron deficiency shows up

• Constant tiredness — even after a full night's sleep
• Breathlessness climbing stairs
• Dizziness or lightheadedness on standing
• Pale skin, brittle nails, hair thinning
• Cravings for ice, chalk, or non-food items (pica)
• Restless legs at night
• Difficulty concentrating; low mood

Why period fatigue is different

Even without full anaemia, blood loss during your period drops iron levels temporarily — you may feel much worse during and just after your period than at other times. If your MyPariva tracker shows fatigue clustered in period days, this pattern points strongly to iron.

What actually helps

• Get tested first. Don't self-supplement without knowing your levels — too much iron has its own problems.
• Iron-rich food: red meat, chicken, fish, eggs, dal, ragi, spinach, black chana, sesame seeds, dates. Combine plant iron with vitamin C (lemon, amla, tomato) — it doubles absorption.
• Skip tea/coffee within 1 hour of iron-rich meals — tannins block absorption.
• Iron tablets if levels are low. Take on an empty stomach with a glass of orange juice if you tolerate it. If tablets upset your stomach, ask about alternate-day dosing — it's often gentler and just as effective.
• Iron infusion — for severe deficiency or when tablets don't work; done as a hospital day-case.

The root cause matters

Fixing iron is important, but so is finding why you're losing so much. If your periods are heavy or long, treating that is what stops the anaemia coming back. See our article on heavy periods.

When to see a doctor

• Fatigue that lasts more than a few weeks
• Breathlessness, dizziness, or hair loss
• Fatigue that reliably peaks around your period
• Heavy periods (see above)
