Can birth control pills cause high prolactin levels?

If you’re anything like me, the idea of taking birth control pills is about as appealing as a root canal. But for some people, it can be a necessary evil in order to prevent unwanted pregnancies or regulate their menstrual cycles. One concern that might come up when considering whether or not to take birth control pills is how they may affect your hormones.

One hormone that has been getting more attention lately is prolactin. This hormone plays a big role in lactation (hence the name), but it also affects other areas of the body such as reproduction and metabolism. Some women who take birth control pills have reported experiencing high prolactin levels, which can cause issues such as irregular periods and decreased sex drive.

But what exactly causes these high prolactin levels? And should you be worried if you’re taking birth control pills yourself? Let’s dig into this issue and see what we can find out.

Understanding Prolactin

Before we dive into the nitty-gritty details of how birth control pills might affect prolactin levels, let’s first discuss what this hormone actually does.

As mentioned earlier, prolactin has a pretty important job when it comes to lactation. During pregnancy, it helps prepare breasts for milk production and after childbirth it stimulates milk production itself (although no promises on whether or not your baby will actually drink any).

But aside from its role in breastfeeding mothers across the globe (shout-out to all my fellow mamas!), prolactin also influences ovulation (which explains why lactating women often experience delayed return of menstrual cycle). It suppresses follicle-stimulating hormone (FSH) and gonadotropins releasing hormone (GnRH) secretion- two hormones need for reproduction – leading to blocked release of eggs from ovaries during menstruation: hence suppressed ovulation. In addition, prolactin affects emotional and cognitive behaviour which might be an explanation for maternal behavior in women after childbirth

So all of this tells us that prolactin is pretty important when it comes to female reproductive health. But what causes prolactin levels to rise? And how do birth control pills factor into this?

Causes of High Prolactin Levels

There are actually quite a few things that can cause a person’s prolactin levels to increase above normal range (2-29 ng/mL) (which, let’s face it, is just about as vague as every other measurement your doctor throws at you). Some common triggers include:

  • Pregnancy and breastfeeding
  • Certain medications (e.g. antidepressants)
  • Strenuous exercise or sexual activity
  • Hypothyroidism
  • Pituitary gland tumors

So if we take a closer look at these potential triggers, it appears that some kind of disruption to the body’s hormonal balance could potentially cause high prolactin levels.

Birth Control Pills and Prolactin Levels

Now here comes the big question: can birth control pills affect your prolactin levels?

As with most medical questions, there isn’t always an easy answer. However so far available studies published by reputable organizations(though limited) suggest that oral contraceptives do not significantly elevate serumprolcatine level however as doses vary different effects may occur.

But wait! Not everything is black and white dogs bark , cats meow!

Some individuals have reported experiencing higher-than-normal prolactin levels while taking birth control pills. According to one study conducted on teenagers with endometriosis found high dose progesterone-only contraceptive increases plasma proclatin concentration beyond upper limit normal range within 6 months (Uthurusamy R et Al A comparative study between Depot Medroxyprogesterne Acetate “DMPA” & Levonorgestrel IUD in the management of perimenapauseal and postmenopausal women with heavy uterine bleeding, J Obstet Gynaecol Res. 2019 Jun;45(6):1168-1174. doi: 10.1111/jog.13956) similar to Depo-Provera injection already well documented, oral contraceptives containing high doses of estrogen can cause prolactin levels to increase as well.

But what about low-dose estrogen birth control pills (as most commonly used)? The evidences are still scanty however it is logical that Low dose ECP have been recommended for breastfeeding mothers as it does not interveins with milk production capacity by suppressing prolactin level or increasing its clearance rate.Some studies also suggest a reduced risk of endometrial cancer mainly due to their effect on sex hormone binding globulin which decreases availability of excess unbound testosterone causing balance between ovarian estorgen and progesterone hence reducing adverse effects.Extensive researches need to be conducted in future inorder for clinicians In making clearer recommendations

Potential Consequences of High Prolactin Levels

So what if you do happen to experience high prolactin levels while taking birth control pills? What kind of impact could this have on your body?

As mentioned earlier, some potential symptoms associated with high prolactin levels include:

  • Irregular menstrual periods
  • Decreased sex drive
  • Vaginal dryness
  • Breast tenderness
  • Weight gain
    -increased anxiety or depression

In addition social implications may arise from these side-effect

While none of these side-effects sound particularly funtastic, it’s essential o note that everyone’s body reacts differently – one person may experience no problems whatsoever while another might find her reproductive health turned upside down.

Should You Be Concerned About Prolactin Levels?

There’s no clear-cut answer as to whether or not you should be worried about high prolactin levels while taking birth control pills. For one, different types of oral contraceptives are going to have varying degrees of progesterone and estrogen hormones in them and subsequently affect hormone profile differently.

But even if your particular pill doesn’t seem to cause any issues with your prolactin levels, it may still lead to other side effects that might be concerning for you personally.

In conjunction, always note personal health needs..Potential advantages like contraceptive efficacy ,regularised menstrual cycle outweighs potential harm by far especially for healthy younger women however In cases wherein there is a history of hormone-dependent diseases/dysfunctions(fibroids,some cancers, polycystic ovary syndrome (PCOS), etc) obtaining professional medical guidance cannot be over emphasized

Final Thoughts

All in all the relationship between birth control pills and high prolactin is complicated at best – ultimately depending on person’s biological differences. While some people may experience unwanted side effects such as irregular periods, decreased sex drive or breast tenderness due to increased prolactin (whether from their prescription drug use or another underlying condition), others may notice no harmful impact whatsoever.

As usual talk with your clinician before beginning/switching/managing hormonal therapies/medications. They will do all tests necessary which includes blood test called serum Prolactine test based on accompanying symptoms combined with patient’s Medical History so as calm any anxiety we might possible generate through this write-up.What can I say? We just couldn’t help but milk the situation!
