Post means "after," and partum means "pregnancy," so postpartum refers to the time period after you have a baby. It's usually considered the first 6 weeks.
Your thyroid is a small gland in the front of your neck. Glands make and release hormones. Hormones stimulate other cells or tissues into action.
Thyroid hormones control how fast your body's chemical functions work (your metabolic rate).
For about 6 months after having a baby, you have an increased risk of getting a thyroid disorder. Over 1 in 20 women get a postpartum thyroid disorder.
