An increasing number of women are encountering misleading information about perimenopause on social media platforms, leading to significant concerns among health experts. This proliferation of inaccuracies could potentially steer individuals towards false conclusions regarding their health, mask underlying medical issues, or even heighten the risk of unintended pregnancies. The fundamental problem lies in the blurred lines between genuine information and unverified claims circulating online, prompting a need for clarity on this crucial phase of women’s health.

Perimenopause is defined as the transitional phase in a woman’s life that precedes menopause. This period is characterized by fluctuating levels of key hormones, particularly oestrogen and progesterone, which can manifest in a variety of symptoms. These may include alterations in menstrual patterns, such as irregular or heavy periods, along with common discomforts like hot flushes, mood fluctuations, and difficulty sleeping. According to Dr. Zara Haider, president of the College of Sexual and Reproductive Healthcare, perimenopause often commences in a woman’s early to mid-40s, though it can begin earlier for some individuals.

Experts are increasingly worried that while social media has undeniably contributed to destigmatizing menopause, it simultaneously serves as a conduit for widespread misinformation. Dr. Haider highlights that women are often drawn to online-marketed supplements or alternative treatments, sometimes forsaking established and effective medical options, frequently at considerable personal expense. The repercussions of such misinformation can be severe, extending to women in their late 30s and early 40s incorrectly assuming they are perimenopausal based on online content, and subsequently discontinuing contraception. Furthermore, perimenopausal symptoms can overlap with those of other serious conditions, such as primary ovarian insufficiency. Dr. Haider strongly advises women with concerns to consult their General Practitioner (GP) to thoroughly investigate their symptoms and ensure continued protection against unintended pregnancy if necessary.

When it comes to contraception during perimenopause, there is no single universally "best" method; rather, the optimal choice is highly individual. Available options include barrier methods like condoms, which offer the added benefit of protection against sexually transmitted infections, and the hormone-free intrauterine device (IUD), although its suitability may vary for women experiencing heavy periods. Dr. Paula Briggs, a consultant in sexual and reproductive health, emphasizes the numerous advantages of hormonal contraception. Beyond preventing unplanned pregnancies, these benefits extend to reducing bleeding and pain, managing conditions like fibroids and endometriosis, and improving acne. Moreover, while some hormonal contraceptives carry a slight increased risk of breast cancer, they can offer protective benefits against other types of cancer.

Progestogen-only contraceptives, which incorporate synthetic progesterone-like substances, come in various forms including patches, the mini-pill, injections, implants, and intrauterine systems (IUS), with some providing protection for several years. These forms of contraception can be particularly effective in mitigating heavy menstrual bleeding. Importantly, Hormone Replacement Therapy (HRT) can be administered concurrently with progestogen-only contraception to alleviate other symptoms associated with perimenopause, offering a comprehensive approach to managing this transitional phase.

The traditional combined pill, comprising ethinyl estradiol – a synthetic form of oestrogen – and a progestogen, is an effective contraceptive but not without its drawbacks. Professor Channa Jayasena, an expert in reproductive endocrinology at Imperial College London, notes that ethinyl estradiol is a potent steroid with oestrogen-like properties, which can elevate the risk of blood clotting. This risk is particularly pronounced in individuals with pre-existing health conditions such as obesity, those who smoke, and it naturally increases with age.

However, the notion that older women cannot use the combined pill is considered erroneous by experts. Dr. Briggs clarifies that age alone is not a contraindication; rather, a thorough assessment of individual risk factors is crucial. These factors include conditions like migraine with aura, being overweight, or hypertension (which, if effectively treated, may still allow access to the combined pill). A significant development in this area is the introduction of a newer generation of combined pills. Professor Jayasena explains that these modern contraceptives contain natural oestrogen, which critically does not carry the same blood clot risk. He describes these as "really good modern, next-generation contraceptive pills," offering a safety advantage that makes them considerably more suitable for women in their 40s, and even their 50s, essentially functioning as a mini-pill with natural oestrogen.

A common question arises regarding the need for contraception when women are already undergoing Hormone Replacement Therapy (HRT). If women have not yet reached menopause, are under the age of 55, and wish to avoid pregnancy, then contraception remains essential. This is because the doses of oestrogen (and progestogen, if the womb is intact) in HRT are generally considered too low, and the substances not potent enough, to effectively prevent the ovaries from releasing an egg.

Finally, "body-identical hormones" refer to natural forms of oestrogen and progesterone that are chemically identical to those produced by the human body, albeit manufactured in a laboratory. While these are utilized in some forms of HRT, with initial research hinting at potential benefits, experts like Professor Jayasena highlight that only non-natural forms of oestrogen and progesterone possess the necessary potency to function as effective contraceptives. Furthermore, there can be specific advantages to non-natural progestogens used in HRT; some exhibit a greater testosterone action, which can enhance libido, while others possess an anti-testosterone action, proving beneficial for women experiencing issues like acne or excess hair. Thus, he concludes, "there are advantages sometimes to deviating from nature."
