Pregnancy Hormones 101

In Pregnancy/Postpartum by pelv_admin4 Comments

Pregnancy is wild. Someone is walking around growing a human being. It blows my mind every time I see a pregnant person and here at The Pelvic Health & Rehabilitation Center, we get to see a lot of pregnant people! 

Now a lot of things happen during pregnancy, and hormones are a big key player in the process. You may recall a blog post I did previously talking about hormones in general. In this post I want to dive in a little deeper and talk about hormones during pregnancy. 

There are several hormones, but let’s focus on the major ones: 

  • Estrogen
  • Progesterone
  • Oxytocin
  • Prolactin
  • Relaxin

Estrogen is probably the most well known hormone. It’s like a Kardashian: big name recognition, but what does it actually do ? During pregnancy, estrogen production increases and it will get up to 30 times its normal levels! The main role estrogen plays is it helps stimulate uterine growth. It will increase blood flow to the vagina and other areas of the body. If you are getting nose bleeds or feeling congested while you are pregnant, estrogen is possibly to blame! 

However, don’t go blaming estrogen for everything. Progesterone is hard at work during pregnancy. In fact, the main job of the ovaries during the first seven weeks of pregnancy is to produce progesterone. This hormone is helping to maintain the endometrial layer that the growing embryo is attached to and it helps maintain the pregnancy. Therefore, low levels of progesterone during a pregnancy increases the risk of a miscarriage. Progesterone is steadily increasing during pregnancy and is one of the main causes of morning sickness. 

Progesterone also stimulates the breast lobes to prepare for milk production and helps the body store more fat as the pregnancy progresses. Progesterone is helping to relax things in the uterus, but other areas of the body can be impacted. For example, the lower part of the esophagus can have decreased tone due to progesterone and this can result in increased heartburn during pregnancy. 

Progesterone isn’t the only hormone helping to relax things during pregnancy. While its name is deceiving, the hormone relaxin has several jobs. It is going to inhibit uterine activity and it will help soften the cervix. Although, it is a myth that it is 100% responsible for relaxing all of the ligaments during pregnancy, it will help relax the joints, such as the pubic symphysis to help get ready for delivery. 

Speaking of delivery, let’s talk about oxytocin which increases at the end of pregnancy and during labor. This hormone is being suppressed by progesterone during pregnancy because oxytocin is going to help stimulate uterine contractions. It will continue to work after the baby is born to help the uterus contract to expel the placenta. This hormone may be used to induce labor or help it progress but is commonly referred to by its brand name: pitocin. Oxytocin also helps stimulate the milk-ejection reflex that is necessary for breastfeeding. 

Breastfeeding happens thanks to a feedback loop created by oxytocin which promotes milk let down and then another hormone, prolactin, which is responsible for milk production. Prolactin will lead to enlargement of the mammary glands and as a result each breast can increase by one pound each! As a result, new moms may notice more back or neck pain. So, it may be a good idea to invest in some good quality bras to make sure your breasts are getting the support they need and deserve! 

The physical therapists at PHRC are experts in helping women prepare for pregnancy, labor and delivery, and recover in the postpartum period. If you want to optimize your musculoskeletal health before, during, or after pregnancy please give us a call!

FAQ

What are pelvic floor muscles?

The pelvic floor muscles are a group of muscles that run from the coccyx to the pubic bone. They are part of the core, helping to support our entire body as well as providing support for the bowel, bladder and uterus. These muscles help us maintain bowel and bladder control and are involved in sexual pleasure and orgasm. The technical name of the pelvic floor muscles is the Levator Ani muscle group. The pudendal nerve, the levator ani nerve, and branches from the S2 – S4 nerve roots innervate the pelvic floor muscles. They are under voluntary and autonomic control, which is a unique feature only they possess compared to other muscle groups.

What is pelvic floor physical therapy?

Pelvic floor physical therapy is a specialized area of physical therapy. Currently, physical therapists need advanced post-graduate education to be able to help people with pelvic floor dysfunction because pelvic floor disorders are not yet being taught in standard physical therapy curricula. The Pelvic Health and Rehabilitation Center provides extensive training for our staff because we recognize the limitations of physical therapy education in this unique area.

What happens at pelvic floor therapy?

During an evaluation for pelvic floor dysfunction the physical therapist will take a detailed history. Following the history the physical therapist will leave the room to allow the patient to change and drape themselves. The physical therapist will return to the room and using gloved hands will perform an external and internal manual assessment of the pelvic floor and girdle muscles. The physical therapist will once again leave the room and allow the patient to dress. Following the manual examination there may also be an examination of strength, motor control, and overall biomechanics and neuromuscular control. The physical therapist will then communicate the findings to the patient and together with their patient they establish an assessment, short term and long term goals and a treatment plan. Typically people with pelvic floor dysfunction are seen one time per week for one hour for varying amounts of time based on the severity and chronicity of the disease. A home exercise program will be established and the physical therapist will help coordinate other providers on the treatment team. Typically patients are seen for 3 months to a year.

What is pudendal neuralgia and how is it treated?

Pudendal Neuralgia is a clinical diagnosis that means pain in the sensory distribution of the pudendal nerve. The pudendal nerve is a mixed nerve that exits the S2 – S4 sacral nerve roots, we have a right and left pudendal nerve and each side has three main trunks: the dorsal branch, the perineal branch, and the inferior rectal branch. The branches supply sensation to the clitoris/penis, labia/scrotum, perineum, anus, the distal ⅓ of the urethra and rectum, and the vulva and vestibule. The nerve branches also control the pelvic floor muscles. The pudendal nerve follows a tortuous path through the pelvic floor and girdle, leaving it vulnerable to compression and tension injuries at various points along its path.

Pudendal Neuralgia occurs when the nerve is unable to slide, glide and move normally and as a result, people experience pain in some or all of the above-mentioned areas. Pelvic floor physical therapy plays a crucial role in identifying the mechanical impairments that are affecting the nerve. The physical therapy treatment plan is designed to restore normal neural function. Patients with pudendal neuralgia require pelvic floor physical therapy and may also benefit from medical management that includes pharmaceuticals and procedures such as pudendal nerve blocks or botox injections.

What is interstitial cystitis and how is it treated?

Interstitial Cystitis is a clinical diagnosis characterized by irritative bladder symptoms such as urinary urgency, frequency, and hesitancy in the absence of infection. Research has shown the majority of patients who meet the clinical definition have pelvic floor dysfunction and myalgia. Therefore, the American Urologic Association recommends pelvic floor physical therapy as first-line treatment for Interstitial Cystitis. Patients will benefit from pelvic floor physical therapy and may also benefit from pharmacologic management or medical procedures such as bladder instillations.

Who is the Pelvic Health and Rehabilitation Team?

The Pelvic Health and Rehabilitation Center was founded by Elizabeth Akincilar and Stephanie Prendergast in 2006, they have been treating people with pelvic floor disorders since 2001. They were trained and mentored by a medical doctor and quickly became experts in treating pelvic floor disorders. They began creating courses and sharing their knowledge around the world. They expanded to 11 locations in the United States and developed a residency style training program for their employees with ongoing weekly mentoring. The physical therapists who work at PHRC have undergone more training than the majority of pelvic floor physical therapists and as a result offer efficient and high quality care.

How many years of experience do we have?

Stephanie and Liz have 24 years of experience and help each and every team member become an expert in the field through their training and mentoring program.

Why PHRC versus anyone else?

PHRC is unique because of the specific focus on pelvic floor disorders and the leadership at our company. We are constantly lecturing, teaching, and staying ahead of the curve with our connections to medical experts and emerging experts. As a result, we are able to efficiently and effectively help our patients restore their pelvic health.

Do we treat men for pelvic floor therapy?

The Pelvic Health and Rehabilitation Center is unique in that the Cofounders have always treated people of all genders and therefore have trained the team members and staff the same way. Many pelvic floor physical therapists focus solely on people with vulvas, this is not the case here.

Do I need pelvic floor therapy forever?

The majority of people with pelvic floor dysfunction will undergo pelvic floor physical therapy for a set amount of time based on their goals. Every 6 -8 weeks goals will be re-established based on the physical improvements and remaining physical impairments. Most patients will achieve their goals in 3 – 6 months. If there are complicating medical or untreated comorbidities some patients will be in therapy longer.
