What are the symptoms of postpartum thyroiditis?
When the thyroid becomes inflamed, it first sends a lot of thyroid hormone into your blood. That causes hyperthyroidism. During this phase, you may not have any symptoms. Or symptoms you do have are usually mild and do not last long. After this first phase, you will either recover completely or your thyroid will be damaged. A damaged thyroid can become underactive. This condition may also go away. Or you may have an underactive thyroid for the rest of your life. In this case you may need hormone replacement.
Below are the most common symptoms of postpartum thyroiditis. But each person may have slightly different symptoms.
Overactive thyroid (hyperthyroidism)
- Feeling warm
- Muscle weakness
- Rapid heartbeat
- Loss of concentration
- Weight loss
Underactive thyroid (hypothyroidism)
- Loss of memory
- Cannot tolerate cold weather
- Muscle cramps
- Weight gain
These symptoms may not appear until several months after childbirth. They are often mistaken for normal signs of recovery from childbirth. Always see your health care provider for a diagnosis.
