What Is Postpartum Thyroiditis?

Postpartum Thyroiditis is an issue that affects some mothers during the first year after delivery. This happens due to the inflammation of the thyroid gland. It is relatively a rare issue. Only 5% of mothers are reported to contract this in the year following the delivery.

Types Of Postpartum Thyroiditis

There are mainly three types of postpartum thyroiditis:

  1. Classic: In the classic type of postpartum thyroiditis, mothers contract hyperthyroidism followed by temporary hypothyroidism. The end of the first-year mother will regain normal thyroid function
  2. Isolated Thyrotoxicosis: In isolated thyrotoxicosis, there will be a period of hyperthyroidism. There will not be an episode of hypothyroidism. The hyperthyroidism, in due course, will resolve itself. This type of PPT is found to begin in-between two to six months after the delivery. Twenty-five percent of women experience this type of PPT.
  3. Isolated Hypothyroidism: Remaining 50% of women with PPT develop an underactive thyroid between three to 12 months after delivery. Although most of the women will get out of this in due course, 10 to 20% of women have an increased chance to develop permanent hypothyroidism.

What Are The Causes Of Postpartum Thyroiditis?

The causes why only a few women witness this condition is not known for the scientists. There is a proper investigation going on why the antithyroid antibodies are produced in the women after pregnancy and why they are attacking her thyroid gland.
However, the medical experts believe that postpartum Thyroiditis starts during the pregnancy itself and just stays silent as an autoimmune disease. However, after childbirth, due to the fluctuations in the function of the immune system, the thyroid gland will get attacked by the immune system triggering PPT.

  • Mothers with Type one diabetes
  • Mothers experiencing postpartum depression
  • There are few people who have an increased number of anti-thyroid antibodies, and even they have the risk of getting this problem after pregnancy.
  • While those who have the autoimmune disorders are also prone to this postpartum Thyroiditis

The accurate rate of PPT is not known; it is not that every one after the pregnancy will be prone to this gets this Postpartum Thyroiditis. Only around 5 to 10% of women contract this issue. The rate is quite high in women who come under the high-risk category.

Doctors also run some tests for diagnosis of Graves’ disease, which can also trigger hyperthyroidism after delivery. There is a radioiodine uptake test that is done to distinguish postpartum thyroiditis from Graves’ disease.  The doctor may go for it in some cases.

Treatment of Postpartum Thyroiditis 

  • When there are very mild symptoms or just the hormonal imbalance has started, there is no necessity for any sort of treatment or therapy.
  • On the other hand, women who are suffering from hyperthyroidism will be given with the beta-blockers. These are useful to reduce the tremors and control other symptoms like increased heart rate or palpitations.
  • Doctors suggest thyroid replacement therapy for those who are troubled with hypothyroidism. The course will be extended for 6-12 months.
  • Depending on the reaction of the patient and her symptoms, these courses will be changed or stopped when the individual is completely fine.
