What Happens to Your Hormones After Birth?

The hormone shift that occurs during pregnancy is well-known and has been highlighted in pop culture. But hormones are less talked about post-delivery.

What happens to a woman's hormones after birth, and how long does it take for them to return to pre-pregnancy levels? Our experts weigh in.

"New moms go through so many different hormonal changes immediately after birth," says Judi R. Gerardis, M.D., an OB/GYN with Hackensack University Medical Center.

"These drastic shifts may cause shivering after delivery, and women may begin to get increased cramping. Some women experience hot flashes," says Lizabeth A. Kopp, M.D., an OB/GYN at Hackensack.

The return to pre-pregnancy hormone levels can vary greatly, but generally hormones will normalize within three to six months.

If you are breastfeeding, as you wean from it, your prolactin and oxytocin levels will drop—potentially leaving you feeling sad, anxious or irritable. These are usually short-lived, but a slow approach to weaning may help reduce adverse effects.

"However, with breastfeeding, hormonal change is very individualized," says Dr. Gerardis, adding that this is due to a variety of factors, such as how often you breastfeed.

Dr. Gerardis and Dr. Kopp offer a few tips for making the transition a bit easier:

While hormonal changes may involve feeling blue, it's important to recognize when it might be something more serious. Signs of postpartum depression may include:

If you are experiencing these signs, talk to your doctor about what you are feeling and about treatment options—even reaching out to a trusted family member or friend can be a good start. And if you ever consider harming yourself or your baby, seek help immediately—either from a health care provider or even by calling 911 in an emergency.

Postpartum depression is more common in women who have a history of depression. "If you have a history of depression, having a game plan in place during pregnancy is key," Dr. Gerardis says.

Adds Dr. Kopp: "Talk with your doctor about continuing or starting medication, and keep up your appointments with your mental health provider."
