That Naughty Little Pill - Birth Control Side Effects

That Naughty Little Pill - Birth Control Side Effects

This post originally appeared on Mad in America as That Naughty Little Pill

It was early in my actualization as a feminist-minded, righteous post-adolescent that I began to think of birth control as a woman's right (who was anyone to tell me that I couldn't assault my hormones with synthetic imposters). It would be years before I would learn about the nuanced considerations of tacit permissiveness toward reckless unprotected sex, the wholesale delegation of contraception to the female counterpart, and the fundamental divorce of a woman from the very feedback systems that fire up her reproductive age vitality.

These concerns would begin to color my perception of this gift from Pharma, well before I began to learn about functional biochemical concerns surrounding the metabolism of synthetic hormones. With over 100 million women using this form of hormonal suppression worldwide, I have to wonder how many of them have any exposure to information about the Pill's subtle but important perturbations to the system, not to mention the consensus risks of thromboembolism, hypertension, cerebrovascular events, gallstones, and cancer.

As notorious as our hormones are for wreaking havoc, they are what pop us into high relief – they excite us, move us, drive us and enliven us.  The highly non-linear relationships between sex hormones, thyroid hormone, and adrenal hormones is like the magic of 3-D glasses: if you cover one lens, things just don't look as exciting.

When patients come to me with complaints of low libido, low or flat mood, weight gain, hair loss, and cloudy thinking, one of my first questions is ,"Are you on the Pill?"  When they come complaining about premenstrual irritability, insomnia, tearfulness, bloating, and breast tenderness, requesting that I sanction beginning a course of oral contraceptives and perhaps an antidepressant, the one-size-fits-all-cure-all of psychiatrists and gynecologists nationwide, my first comment is "There's a better way."

The signs of hormonal imbalance are often quickly dismissed as a problem too complex to rectify from its source. In my practice, I first look at diagnostics to better personalize dietary recommendations, targeted nutritional interventions, and herbal options to promote the body's own drive toward harmony. If it's not enough to celebrate their right to an optimally functioning hormonal system, and they also want to preserve their right not to have a fertilized egg, then I recommend a non-hormonal IUD, nifty gadgets like the Pearly, or the good ol' fashioned condom.

Why is it that I think rendering a woman a 2-dimensional version of her hormonal self is such a big deal?  Simply because, if she's in my office, she is someone who has struggled with mood and anxiety, and the last thing she should be doing is stacking the cards against her recovery with synthetic hormones and the pharmacologic burden they bring. Since the 1960s, there has been controversy around the potential mood effects of oral contraceptives, but over 50 years of their use has not settled the question.

There is acknowledgement; however, that depression is the most common reason for discontinuation of use. I don't need pilot studies that demonstrate women using the combined oral contraceptive pill were significantly more depressed than a matched group who were not, to persuade me because I see it first hand, most notably, in those who begin contraception (hormonal IUD, progestin-only, or combined) postpartum.

The data, overall, is compromised by inconsistent assessments of mood pathology across the cycle and between groups, and often by study design, but suggests that there is likely a subset of women for whom oral contraceptives represent a major risk factor for depression and/or related mood disturbance.

Who might these women be? From 13 prospective trials, it appears that they have a personal or family psychiatric history (though doesn't that include the entire population at this point?), one that has been exacerbated by pregnancy/postpartum, and premenstrual periods, and young age. More specifically, women with premenstrual mood symptoms prior to use experience more adverse effects with lower progestin dosages or triphasic OCs, unlike women without this history who experience more psychiatric side effects with higher progestin preparations.

Could these side effects be just coincidence? Could they represent "confounding by indication" or the fact that many women who opt to suppress their cycle might already be prone to depression?  It's possible, but so are some of these important mechanistic insights:

  • Synthetic hormones like those in combined oral contraceptives increase thyroid and sex hormone binding globulin, effectively decreasing the available testosterone and thyroid hormone in circulation (which can render you of nun-like libido, and functionally hypothyroid or depressed, constipated, overweight, cloudy, with dry skin and hair, to boot!). A randomized, open-label, 9 week trial of 3 forms of hormonal contraception found that they all increased SHBG, as well as insulin resistance, and markers of inflammation such as c-reactive protein ...
