The short explanation
Exhaustion with a new baby is common at any age, but it is reasonable to check for medical causes. Anaemia is common after delivery, especially if you lost blood at birth, and thyroid problems can appear in the months after childbirth. Low mood and postnatal depression can also cause deep tiredness. A doctor can arrange simple blood tests, including haemoglobin and thyroid function, and ask about your mood and sleep.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Recovery can take longer after a caesarean, a complicated birth, or if you had high BP or diabetes in pregnancy.
- Sharing night feeds, accepting help, and resting during the day where possible can help while you wait for results.
- Tell the doctor about other symptoms such as palpitations, feeling cold, weight changes, breathlessness or low mood.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell what is causing your tiredness. Blood tests and an assessment are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Should I have my haemoglobin and thyroid checked?
- Could this be postnatal depression?
- Is my recovery slower because of my age or the type of birth?
- What can help me get more rest?
