Postpartum Thyroiditis: Thyroid Problems After Delivery
By Dr. Moxit Shah, DM Endocrinologist
Vishuddha Endocrine Clinic, Ahmedabad
After delivery, tiredness, mood changes, palpitations and weight changes are often put down to “being a new mother”.
Sometimes, the thyroid is the cause.
Postpartum Thyroiditis is inflammation of the thyroid gland in the first year after childbirth. It is common, frequently missed, and usually temporary, but it needs the right diagnosis because the treatment is different from other thyroid conditions.
What is Postpartum Thyroiditis?
During pregnancy the immune system is naturally quieter. After delivery it becomes active again, and in some women it attacks the thyroid, causing inflammation.
It can also occur after a miscarriage or termination.
Who is at higher risk?
- Women with positive Anti-TPO antibodies
- Women who had Postpartum Thyroiditis in a previous pregnancy
- Women with Type 1 Diabetes or other autoimmune conditions
- A family history of thyroid disease

What are the phases of Postpartum Thyroiditis?
It classically has two phases, although many women have only one.
| Phase | Usual timing | What happens |
|---|---|---|
| Overactive (thyrotoxic) | About 1–4 months after delivery | Stored hormone leaks out of the inflamed gland |
| Underactive (hypothyroid) | About 4–8 months after delivery | The gland is temporarily unable to make enough hormone |
| Recovery | Usually within about 12–18 months | Most women return to normal thyroid function |
What are the symptoms?
Overactive phase:
- Palpitations
- Anxiety or irritability
- Difficulty sleeping, even when the baby sleeps
- Heat intolerance
- Rapid weight loss
Underactive phase:
- Marked tiredness
- Low mood
- Feeling cold
- Dry skin, hair fall
- Difficulty losing pregnancy weight
Many mothers say:
“I thought it was just lack of sleep.”
Because symptoms overlap with Postpartum Depression, thyroid tests are often recommended when a new mother has depressive symptoms.
How is it different from Graves’ Disease?
Graves’ Disease can also appear after delivery and causes an overactive thyroid, but it needs very different treatment.
Doctors distinguish them using TSH receptor antibodies, the pattern of symptoms and eye signs. Radioactive iodine scans are avoided while breastfeeding.

How is Postpartum Thyroiditis treated?
Overactive phase:
Antithyroid medicines are not used, because the thyroid is leaking hormone, not overproducing it. If symptoms are troublesome, a beta-blocker, chosen to be suitable during breastfeeding, can control palpitations and tremor. The phase settles on its own.
Underactive phase:
Levothyroxine may be started if symptoms are significant, TSH is clearly raised, or if you are breastfeeding or planning another pregnancy. It is safe while breastfeeding. After some months, the doctor may try reducing it to see whether the thyroid has recovered.
See how to take Levothyroxine correctly.
Can it become permanent?
Most women recover. However, a significant proportion develop permanent Hypothyroidism over the following years, especially those with positive Anti-TPO antibodies.
That is why a yearly TSH test is recommended after Postpartum Thyroiditis. It also often recurs in future pregnancies, so tell your doctor before your next pregnancy.
