Does birth control cause weight gain?

Choosing the right birth control often means considering factors like how good it is at preventing pregnancy, how easy it is to use, cost, and, of course, how it makes you feel. One common concern for many people is whether birth control might lead to weight gain. While side effects vary depending on the method, understanding the connection between birth control and weight changes can help you make the best choice for your body and lifestyle.

The science behind weight gain and birth control

Let’s look at the research to understand the link between weight gain and birth control. Birth control can have different effects on each person, depending on the method and their body’s unique chemistry. Many hormonal birth control options rely on a combination of estrogen and progestin, or just progestin, which influence the body in various ways.

While these factors might contribute to weight changes for some people, it’s worth noting that significant weight gain (more than three to five pounds) from birth control is very uncommon.

Does birth control always cause weight gain?

No, weight gain isn’t a guaranteed side effect of birth control. It’s a common concern, but the truth is that most modern birth control options are designed with low hormone doses, reducing the chances of unwanted weight changes.

‍

Another element to consider is lifestyle. Many people start birth control when they start a sexual relationship, which is great. However, changes that can come with a relationship (like going out to eat, or Netflix and chill) may also contribute to weight changes. The bottom line is that if you move the same—and eat the same—the risk of weight gain on birth control is pretty low.

‍

It’s also worth noting that everyone’s body reacts differently. If you do notice weight gain and find it bothersome, your health care provider can work with you to explore alternatives. The right birth control is out there for you, but sometimes, it just takes a little trial and error to find the perfect match.

If you have any concerns about weight gain, please discuss these options with your health care provider. They can help you consider the pros and cons of each medication.

Does non-hormonal birth control cause weight gain?

If you’re looking for a method that’s unlikely to affect your weight, non-hormonal birth control might be your best bet. Options like the copper IUD and barrier methods (e.g., condoms, diaphragms) don’t contain hormones, so they won’t impact your metabolism, appetite, or fluid retention. These methods are great for those who want effective birth control without the potential side effects of hormones.

How to manage weight gain from birth control

If you’re experiencing weight gain that you think is linked to your birth control, don’t worry—there are steps you can take:

1. Talk to your health care provider: They can help determine if your birth control is the cause and suggest alternatives. Switching methods may resolve unwanted side effects.
2. Lifestyle adjustments: If you haven’t already, implement regular physical activity and a balanced diet to prevent changes in your appetite or metabolism.
3. Be patient: It’s common for side effects to settle after the first three months of starting a new birth control method. Your body may just need time to adjust.
4. Track your symptoms: Keeping a record of changes in weight, appetite, or bloating can help you and your health care provider identify patterns and find solutions.
