Birth Control Pills: The Basics

The birth control pill or the oral contraceptive pill is one of the most widely used and reliable forms of contraception, providing women with the ability to take control over their reproductive health. Since its introduction almost 60 years ago, it has become a cornerstone in family planning, offering not only a means of preventing pregnancy but also a host of other health benefits. However, like any medication, it comes with its own set of advantages and limitations, and understanding these can help women be in control of their reproductive health.

 

Key Takeaways:

  • The birth control pill prevents pregnancy by stopping ovulation, thickening cervical mucus, and thinning the uterine lining.

  • With perfect use, the pill is over 99% effective. With typical use, it is around 91%, emphasizing the need for consistent, daily use.

  • Beyond contraception, the pill can regulate periods, reduce menstrual pain, and lower the risk of ovarian and endometrial cancers.

  • The pill can cause side effects like headaches and mood changes in some women, and it is not suitable for women with certain health conditions or those who forget to take it regularly.

 

What is the Birth Control Pill?

What is the Birth Control Pill?

A birth control pill, or commonly called "the pill", is a type of contraception method. It is used by women, and taken orally once a day. There are various brands and formulations available, however majority of them contain two hormones - estrogen and progestogen (progestin), which is why these are also referred to as combined hormonal contraceptive (CHC) pills, or combined oral contraceptive (COC) pills. The natural forms of these two hormones help regulate the menstrual cycle and play an important role in reproductive health.

In addition to having a contraceptive effect, birth control pills have several non-contraceptive benefits as well. If you are considering this form of contraception, it is important that you make an informed decision, and ensure that you are aware of its effectiveness as well as potential risks and benefits.

How Does the Birth Control Pill Work?

The birth control pill works in three ways:

  • It primarily works by preventing ovulation, the process where an egg is released from the ovaries during the menstrual cycle. Without the egg being released, the chance of it being fertilised by a sperm and resulting in a pregnancy is virtually eliminated.

  • Additionally, the pill thickens the mucus in the cervix, making it difficult for sperm to travel and reach the egg after sex.

  • It also thins the inner lining of the uterus reducing the likelihood of a fertilized egg getting implanted in the uterus successfully.

This threefold mechanism ensures high efficacy when the pill is used correctly and consistently. However, its effectiveness can vary based on user habits and external factors like medication interactions or digestive issues.

The birth control pill is a very effective method of contraception, however it is also highly user-dependent, and its effectiveness is based on its typical or perfect use.

Perfect use means that you use the pill consistently, without missing any pills, and once a pack/cycle is finished start the new pack on time. Typical use means that you don't always take the pill consistently or correctly.

If used perfectly, the pill is more than 99% effective, which means the risk of contraceptive failure with the pill is less than 1%. With typical use, however, when the pill is not taken consistently or restarted on time, it is estimated to be 91% effective.

Other factors can also influence the pill's reliability. For instance, certain medications or herbal supplements may interfere with its absorption, as can vomiting or diarrhoea. To maintain optimal protection, it is essential to consult a doctor about potential interactions and report any health changes while on the pill.

The birth control pill offers several benefits beyond simply preventing pregnancy. Many women opt for this method of contraception not only for its reliability but also for the health advantages it can bring.

  1. Regulating Menstrual Cycles:

    One of the most commonly cited benefits of the birth control pill is its ability to regulate the menstrual cycle. For women who experience irregular periods, heavy bleeding, or intense menstrual cramps, the pill can bring relief. It works by controlling hormone levels, which in turn can result in more predictable cycles. This can be especially beneficial for women who have conditions such as polycystic ovarian syndrome (PCOS) or endometriosis, both of which can cause irregular or painful periods.

  2. Reducing Menstrual Pain:

    The pill can help reduce menstrual cramps by stabilizing the hormones that trigger the painful contractions of the uterus. Women suffering from primary dysmenorrhea (painful periods) often find that the pill helps to ease this discomfort. Studies have shown that the pill, when used consistently, can significantly reduce the severity of cramps, making it a preferred option for many.

  3. Improves Acne:

    Many women notice a visible improvement in their skin when they start taking the birth control pill, especially if they suffer from hormonal acne. Pills containing progestin and estrogen can help balance hormone levels, leading to fewer breakouts and clearer skin. This is particularly true for women who struggle with acne around their menstrual cycle or those with PCOS, as it helps regulate the hormones that contribute to excessive oil production in the skin.

  4. Long-Term Health Benefits:

    In addition to the immediate benefits, the birth control pill has long-term health advantages. It has been shown to reduce the risk of ovarian, endometrial, and colorectal cancers. The longer a woman takes the pill, the greater the reduction in risk for ovarian and endometrial cancers. This protective effect can last for many years, even after discontinuing the pill. For example, studies have found that women who use the pill for five or more years may have a significantly lower risk of developing these cancers.

  5. Preventing Ovarian Cysts:

    Women who take the pill are less likely to develop ovarian cysts, as the pill prevents ovulation. This means there is less opportunity for follicles to develop into cysts. This can be a great relief for women who suffer from recurrent cysts or have been diagnosed with PCOS.

  6. Reducing Risk of Pelvic Inflammatory Disease (PID):

    The pill also offers protection against pelvic infections, which can lead to conditions such as pelvic inflammatory disease (PID). By thickening cervical mucus, the pill makes it harder for bacteria to enter the uterus, reducing the risk of infections. Women who are prone to PID or other infections of the reproductive tract may find the pill particularly beneficial.

  7. Convenience and Non-Invasive:

    The birth control pill is a convenient and non-invasive method of contraception. Unlike intrauterine devices (IUDs) or implants, which require a doctor for placement, the pill can be taken privately and requires no physical procedures. This ease of use, along with its effectiveness when taken correctly, makes it an attractive option for many women who want reliable, hassle-free birth control.

What are the Disadvantages of the Pill?

What are the Disadvantages of the Pill?

While the pill offers many benefits, it is important to also consider its potential drawbacks. It may not be suitable for all women, and in some cases, its use can lead to undesirable side effects. These issues need to be carefully evaluated before starting the pill.

  1. Reliance on Consistency:

    One of the biggest drawbacks of the birth control pill is that it relies heavily on user consistency. The pill must be taken every day at about the same time to ensure maximum effectiveness. Missing a dose, or taking it late, can increase the risk of pregnancy. This makes the pill less suitable for women who have difficulty remembering to take it regularly or those with busy lifestyles.

  2. Potential Side Effects:

    Some women may experience side effects when taking the birth control pill. These can include mood changes, headaches, nausea, weight gain, and breast tenderness. These side effects are often temporary and may eventually subside, but they can still be bothersome. In some cases, the pill can also cause some bleeding outside of the usual menstrual period, especially when first starting it. It can also cause periods that are lighter or heavier than usual and may take some time to adjust.

  3. Risk of Blood Clots:

    For some women, the birth control pill may increase the risk of blood clots, particularly in women who are smokers, over 35, or have certain underlying medical conditions. The combination of estrogen and progestin in some pills can increase the likelihood of developing deep vein thrombosis (DVT) or pulmonary embolism (PE). These serious conditions can lead to life-threatening complications, so women with a history of blood clots or related conditions should consult with a doctor before using the pill.

  4. Do not Prevent STIs:

    Another key disadvantage is that the birth control pill does not protect against sexually transmitted infections (STIs). For women who are at risk of STIs, especially in cases of non-monogamous relationships or if their partner's sexual history is uncertain, additional protection such as condoms is necessary. While the pill is highly effective in preventing pregnancy, it does not provide any barrier to the transmission of infections like HIV, chlamydia, or gonorrhoea.

  5. Possible Weight Gain and Appetite Changes:

    Although research does not strongly support a direct link between the pill and significant weight gain, some women report changes in their appetite or weight while using the pill. This can be due to hormonal fluctuations that affect appetite, metabolism, or water retention. For those who are sensitive to these changes, it may be necessary to switch to a different form of contraception.

  6. Health Risks for Certain Women:

    The pill may not be suitable for women with certain pre-existing conditions. For example, women who suffer from liver disease, breast cancer, or certain types of cardiovascular disease may be advised against using the pill due to the hormones involved. Women who smoke and are over the age of 35 are also advised to consider alternative methods of contraception, as the risk of blood clots and other complications may be higher in this group.

Conclusion

The birth control pill remains one of the most popular and effective methods of contraception worldwide. While it offers numerous benefits such as menstrual regulation, acne reduction, and long-term health advantages, it also comes with certain risks and challenges. It is important to make an informed decision about contraception, taking into account personal health, lifestyle, and preferences.

Before starting the pill, it is advisable to consult with a doctor to ensure it is the right option. Understanding the pros and cons, and considering factors such as lifestyle and health conditions, will help women make the best decision for their individual needs. If you have any concerns about contraception, don’t hesitate to reach out to a doctor who can provide tailored advice.
