Hormonal birth control is often hailed as a revolutionary tool for women's autonomy, allowing them to take control of their reproductive health. However, behind the convenience and widespread use, there are growing concerns about the long-term health effects and side effects that many women experience, which are often downplayed or overlooked. This article dives into the darker side of hormonal contraceptives, exploring their potential impact on mental and physical health.
How Hormonal Birth Control Works
Hormonal contraceptives, including the pill, patches, implants, and hormonal IUDs, primarily work by altering a woman’s natural hormone balance. They typically contain synthetic versions of oestrogen and/or progestin (a synthetic form of progesterone), which prevent ovulation, thicken cervical mucus, and thin the uterine lining to reduce the likelihood of pregnancy.
While effective at preventing unwanted pregnancies, these hormone changes can affect other systems in the body in ways that are not always positive.
The Psychological Toll: Depression and Mood Changes
One of the most significant, yet under-discussed, side effects of hormonal birth control is its impact on mental health. Studies have shown a clear link between hormonal contraceptive use and an increased risk of depression and mood disorders.
A landmark study conducted in Denmark in 2016 tracked over one million women and found that those using hormonal contraceptives were more likely to be diagnosed with depression or prescribed antidepressants. Adolescents were particularly vulnerable, with teenage girls on hormonal birth control showing an 80% higher risk of developing depression compared to non-users. This research brought much-needed attention to the potential psychological consequences of these drugs, but despite this, mental health side effects are still often minimised in medical consultations.

For many women, the emotional side effects can be severe. Some report experiencing a sense of emotional numbness or loss of interest in activities they once enjoyed, while others feel heightened anxiety or irritability. For some, these feelings are transient, but for others, they persist, leading to the use of additional medication like antidepressants, without addressing the root cause: their hormonal contraceptive.
Physical Complications: The Risks to Your Body
Beyond mental health concerns, hormonal birth control can also lead to a number of serious physical complications. While the risk of dangerous side effects like blood clots, strokes, and heart attacks is well-documented, it is still often underplayed by healthcare providers.
Blood Clots and Stroke
One of the most serious risks associated with hormonal contraceptives, particularly those containing oestrogen, is the increased chance of developing blood clots, also known as deep vein thrombosis (DVT). These clots can travel to the lungs, causing a potentially fatal condition known as a pulmonary embolism. Studies have shown that women using oestrogen-containing contraceptives are at higher risk of blood clots compared to non-users. The risk increases for women who smoke or are over the age of 35, but even young, healthy women are not immune.
Similarly, stroke risk is elevated in hormonal contraceptive users, particularly those with a history of migraines, as oestrogen can increase blood pressure and the likelihood of clot formation.
Cardiovascular Issues
Hormonal contraceptives can also contribute to high blood pressure and raise cholesterol levels, putting extra strain on the heart. While the absolute risk may be small for healthy, younger women, those with pre-existing cardiovascular conditions or a family history of heart disease may be more vulnerable.
Cancer Risk: Fact vs. Fiction
The relationship between hormonal contraceptives and cancer risk is complex and varies depending on the type of cancer. Some studies suggest that long-term use of the pill may slightly increase the risk of breast and cervical cancers. A large study published in the New England Journal of Medicine found that women who used hormonal birth control had a 20% increased risk of breast cancer, with the risk rising the longer the contraception was used.

However, hormonal contraceptives are also associated with a decreased risk of other types of cancer, such as ovarian, endometrial, and colorectal cancers. This duality complicates the conversation around cancer risk and hormonal birth control, leaving many women unsure about how to weigh the benefits against potential dangers.
Hormonal Imbalance and Reproductive Health
Using hormonal contraceptives long-term can also affect a woman’s reproductive health, potentially leading to problems when she decides to discontinue use and conceive. Some women experience a delay in returning to normal ovulation after stopping hormonal birth control, which can make it difficult to get pregnant right away. Others report disrupted menstrual cycles, prolonged periods of amenorrhea (the absence of menstruation), or irregular bleeding patterns, which can take months to stabilise.
There is also some evidence suggesting that long-term use of hormonal contraceptives may be linked to an increased risk of conditions like polycystic ovary syndrome (PCOS) or exacerbate symptoms in women who are already predisposed to the disorder.
Hormonal Contraceptives and Libido
A lesser-known side effect of hormonal birth control is its impact on libido. Many women report a decreased sex drive while using these medications, which can negatively affect their relationships and sense of well-being. The reason for this is thought to be related to the suppression of natural testosterone production, a hormone that plays a key role in sexual desire for both men and women.
Why Aren’t We Being Told?
Given the wide array of side effects associated with hormonal contraceptives, why aren’t women being adequately informed? In many cases, doctors may consider the benefits—such as effective pregnancy prevention and reduced risk of certain cancers—to outweigh the potential risks. Additionally, some side effects are downplayed or normalised in medical discussions, leading women to accept them as just part of the experience.
There is also a cultural aspect to consider. Historically, women’s health issues have often been minimised or ignored, and this extends to the side effects of contraceptives. For too long, the narrative surrounding hormonal birth control has focused almost exclusively on its benefits, while the risks are swept under the rug.
Seeking Alternatives
For women who are concerned about the potential long-term effects of hormonal birth control, there are alternatives. Non-hormonal options, such as the copper IUD, condoms, or fertility awareness methods, offer contraception without the hormonal side effects. While these methods may not be as convenient or widely promoted, they provide valuable options for those looking to avoid the potential risks of hormonal birth control.
Informed Choices Matter
Hormonal birth control has undoubtedly transformed women’s lives, giving them the freedom to manage their reproductive health with relative ease. But it’s essential that women are fully informed of the potential side effects—both mental and physical—so they can make informed choices that align with their health and well-being. Rather than dismissing concerns, healthcare providers must engage in open, honest discussions about the risks associated with hormonal contraceptives and present women with all of the available options. Only then can women make truly empowered decisions about their health.
