Does Birth Control Pills Make You Gain Weight? Debunking the Myths and Understanding the Science


When it comes to birth control pills, there are a lot of misconceptions out there. One of the most common concerns is whether or not they can cause weight gain. However, the evidence is far from clear-cut. In this article, we’ll take a closer look at the science behind birth control pills and weight gain, as well as provide some tips for maintaining a healthy weight while taking them.

Myths and Truths: Debunking the Link Between Birth Control Pills and Weight Gain

One of the biggest myths surrounding birth control pills is that they cause weight gain. However, studies have shown that this is not always the case. While some women may experience weight gain while taking birth control pills, others may not notice any difference at all.

One large study conducted in 2014 examined the weight changes of over 1,000 women over a two-year period while taking various forms of contraception, including birth control pills. The study found that while some women did experience weight gain, the changes were typically small and varied depending on the type of birth control the women were using.

Another study conducted in 2017 found that women who used a type of birth control containing drospirenone were actually less likely to experience weight gain than those using other forms of birth control.

While individual experiences may vary, the evidence as a whole suggests that birth control pills are not a significant contributor to weight gain for most women.

Understanding the Science: How Birth Control Pills Affect Your Weight

So if birth control pills don’t cause weight gain, what’s going on? In order to understand the relationship between birth control pills and weight, it’s important to look at the hormonal changes that they cause.

Birth control pills work by altering the levels of hormones in a woman’s body. Specifically, they prevent the ovaries from releasing an egg each month by delivering synthetic versions of estrogen and progesterone to the body. This alters the hormonal balance of the body and prevents ovulation from occurring.

Changes in hormone levels can impact weight and metabolism in a number of ways. For example, estrogen is known to impact the way that the body stores and utilizes fat. When levels of estrogen are lower (as they are when taking birth control pills), the body may be more likely to store fat, leading to weight gain.

In addition, some types of birth control pills may cause the body to retain fluid, which can also contribute to weight gain. This is more likely to occur for women who are sensitive to changes in their fluid balance.

Healthy Habits: Tips for Maintaining a Healthy Weight on Birth Control Pills

While birth control pills may not cause weight gain in most women, there are several steps that women can take to maintain a healthy weight while taking them.

First and foremost, it’s important to adopt healthy lifestyle habits. This includes eating a balanced diet, getting regular exercise, and getting enough sleep. These habits will help to maintain a healthy weight and minimize any potential weight gain associated with birth control pills.

Regular exercise is particularly important. Women who exercise regularly are less likely to experience weight gain while taking birth control pills than those who lead sedentary lifestyles. Aim for at least 150 minutes of moderate-intensity exercise per week, such as brisk walking or cycling, and consider incorporating strength-training exercises as well.

In addition to lifestyle habits, it’s also important to pay attention to other factors that can contribute to weight gain. Stress, for example, can impact hormone levels and lead to weight gain, so it’s important to find healthy ways to manage stress. Lack of sleep can also impact hormone levels and metabolism, so aim for at least seven hours of sleep per night.

Navigating Your Options: Choosing the Best Birth Control Pill for You

When it comes to choosing a birth control pill, there are several factors to consider. Some women may be more sensitive to hormonal changes than others, so it’s important to choose a pill that works best for your individual needs.

There are two main types of birth control pills: combination pills and progestin-only pills. Combination pills contain both estrogen and progesterone, while progestin-only pills (also known as “mini-pills”) contain only progesterone.

Combination pills are more commonly prescribed and tend to be more effective at preventing pregnancy. However, they may also be more likely to cause side effects, such as nausea or headaches.

Progestin-only pills are a good option for women who cannot take estrogen, as well as those who experience side effects from combination pills. However, they tend to be less effective at preventing pregnancy than combination pills, so it’s important to use them as directed.

Hormonal Changes and Weight: What Women Need to Know About Birth Control Pills

Finally, it’s important to recognize that hormonal changes throughout the menstrual cycle can impact weight as well. This can vary from woman to woman, but many women experience weight fluctuations throughout the month in response to hormonal changes.

Birth control pills can impact these hormonal changes by altering the levels of estrogen and progesterone in the body. This can help to regulate menstrual cycles and minimize weight fluctuations caused by hormonal changes.

Overall, while birth control pills may not cause weight gain, they do impact the hormonal balance of the body and can potentially contribute to weight gain in some women. By adopting healthy lifestyle habits and paying attention to other factors that can impact weight, women can maintain a healthy weight while taking birth control pills.


While the link between birth control pills and weight gain is often misunderstood, the evidence suggests that birth control pills are not a significant contributor to weight gain for most women. By understanding the science behind hormonal changes and adopting healthy lifestyle habits, women can maintain a healthy weight while taking birth control pills. It’s also important to consider individual factors when choosing a birth control pill and to seek medical advice and support when needed.
