O que é a síndrome pós-anticoncepcional?

There are many reasons you might choose to stop taking birth control - whether it's because you can no longer take it, no longer need it, or simply no longer want to.

Debbie Grayson, Pharmacist and Nutritional Therapist, Practice With Confidence, Greater Manchester, UK explains that post-birth control syndrome (PBCS) refers to a collection of symptoms that some people have after discontinuing hormonal contraceptives.

"PBCS is not an officially recognised medical diagnosis, but the symptoms are real and can be distressing," she says. "They typically emerge within four to six months after stopping birth control."

You may experience breast tenderness, a decrease in sex drive, and weight gain - though this last symptom could be influenced by various factors unrelated to your birth control.

What causes post-birth control syndrome?

Most forms of birth control work to prevent pregnancy, by releasing synthetic hormones into your body that stop your ovaries from releasing eggs. If there is no egg to be fertilised, then sperm is unable to fertilise it during sex to make a baby.

There are eight types of birth control available in the UK, all of which are free through the NHS. You can access them via your doctor, sexual health clinics, or selected pharmacies.

After you stop taking birth control, its effects typically disappear within about a month.

Grayson explains, however, that during this time, your body's hormone levels will take some time to adjust.

"This can lead to temporary disruptions," she explains. "Factors such as nutrient depletion, gut health, and hormonal detoxification play roles in this transition."

As mentioned above, PBCS is not currently recognised as a health condition in the UK. As a result, you cannot seek a formal diagnosis from your doctor, even if you are having symptoms that may be related to it.

However, if you’re having symptoms such as irregular periods, mood swings, acne, fatigue, or digestive issues, it’s important to seek advice from a healthcare professional.

Grayson explains that there are several supportive strategies you can focus on to help restore your body’s natural balance and processes.

Top up on nutrients

Research suggests that hormonal contraceptives may deplete essential nutrients - such as B vitamins, magnesium, zinc, and vitamin C. Replenishing these through a balanced diet or targeted supplements can support your energy levels, mood, and overall hormonal health.

Boost your hormonal balance

Supporting your body’s natural hormone production is key to overall wellbeing.

Keep your gut healthy

The health of your gut plays a crucial role in hormone metabolism and detoxification. Maintaining a healthy gut microbiome can help reduce symptoms such as bloating, acne, and mood swings.

Grayson recommends checking in with a healthcare professional for personalised guidance after stopping birth control.

If you choose to come off it, it's important to tell your doctor so they can support you through the transition and help manage any after-effects.

It can take up to three months for your body to adjust after stopping birth control, and irregular periods during this time are common. However, if your menstrual cycle hasn’t settled after three months or if you’re having symptoms that interfere with daily life - such as painful or heavy periods - it’s important to speak with your doctor. They can offer tailored advice, support and, in some cases, may perform clinical tests or physical examinations to identify the underlying cause of your symptoms.
