Does Birth Control Make You Gain Weight?

Does Birth Control Make You Gain Weight

The relationship between birth control and weight gain is a topic of much debate and often conflicting information. While some women report weight changes, including weight gain, after starting or stopping birth control, the scientific evidence on this matter is not entirely conclusive.

Several studies have examined the potential link between hormonal contraceptives and weight changes, and the findings suggest that the impact on weight is generally modest and varies among individuals. A review of 45 studies on the subject found that hormonal birth control, including both combination pills and progestin-only methods, did not significantly contribute to weight gain in the majority of women.

However, it is important to note that individual responses can differ, and some women may experience more pronounced weight fluctuations. Certain factors, such as the type of birth control, dosage, and the user’s physiology, can play a role in determining the likelihood and extent of weight changes.

Complexities Of Post Birth Control Weight Gain

The reasons behind weight gain after stopping birth control are multifaceted and not fully understood. While hormonal changes are often cited as the primary driver, other factors, such as lifestyle modifications, pre-existing conditions, and individual differences, can also contribute to post-contraceptive weight fluctuations.

Hormonal Shifts

When a woman discontinues the use of hormonal birth control, her body must adjust to the absence of synthetic hormones, such as estrogen and progestin, which were previously supplied by the contraceptive method. This hormonal shift can trigger a cascade of physiological changes that may lead to weight gain.

One of the key mechanisms is the return of the body’s natural ovulation and menstrual cycle. During this transition, women may experience fluctuations in their natural hormone levels, including increases in hormones like testosterone and estrogen. These hormonal changes can affect various bodily functions, including metabolism, appetite, and water retention, all of which can contribute to weight fluctuations.

Additionally, some women may have been using birth control to manage conditions like polycystic ovarian syndrome (PCOS) or endometriosis[Source: WHO], which can also impact weight. When these conditions are no longer being managed by the contraceptive, the associated weight changes may resurface.

Metabolic Adjustments

Hormonal birth control can also influence the body’s metabolic rate, which is the rate at which the body burns calories. Some research suggests that certain hormonal contraceptives may slightly lower the resting metabolic rate, meaning the body may burn fewer calories at rest. When these women discontinue birth control, their metabolic rate may return to its pre-contraceptive level, potentially leading to weight gain if dietary and exercise habits remain unchanged.

Appetite And Cravings

The hormonal changes associated with stopping birth control can also impact appetite and food cravings. Some women report an increase in hunger and a stronger desire for certain foods, particularly those high in carbohydrates or fat, after discontinuing hormonal contraception. This shift in appetite and cravings can contribute to an increase in caloric intake, potentially resulting in weight gain.

Factors Influencing Weight Changes Post-Birth Control

While the hormonal and metabolic factors discussed above can play a significant role in post-birth control weight changes, it’s important to recognize that each woman’s experience may be unique. Several additional factors can influence the extent and timing of weight fluctuations, including:

The specific hormonal makeup and delivery method of the contraceptive used can impact the severity and duration of weight changes. For example, studies suggest that progestin-only methods, such as the mini-pill or the hormonal IUD, may be less likely to cause significant weight gain compared to combination hormonal contraceptives.

The length of time a woman has been using hormonal birth control can also affect the body’s response when discontinuing the medication. Women who have used contraceptives for an extended period may experience more pronounced hormonal shifts and a longer adjustment period when stopping.

Each woman’s unique biology, including factors like age, body mass index (BMI), and pre-existing health conditions, can influence how their body responds to changes in hormone levels and the subsequent impact on weight.

Changes in diet, physical activity, and overall lifestyle habits during and after the discontinuation of birth control can also play a significant role in weight management. Factors such as stress levels, sleep quality, and hydration can further influence weight fluctuations.

Certain medical conditions, such as thyroid disorders, insulin resistance, or Polycystic Ovary Syndrome PCOS, can contribute to weight gain or make it more challenging to manage weight changes after stopping birth control. Addressing these underlying issues with the guidance of a healthcare provider is crucial.

How Do Birth Control Pills Work?

To better understand the potential impact of stopping birth control on weight, it’s important to first understand how hormonal contraceptives, such as birth control pills, work.

Combination birth control pills, the most commonly prescribed form of hormonal contraception, contain synthetic versions of the female hormones estrogen and progestin. These hormones work in several ways to prevent pregnancy:

1. Ovulation Suppression

The estrogen and progestin in the pill prevent the ovaries from releasing a mature egg (ovulation), which is necessary for pregnancy to occur.

2. Cervical Mucus Thickening

The progestin in the pill thickens the cervical mucus, creating a barrier that makes it difficult for sperm to enter the uterus and reach the egg.

3. Endometrial Thinning

The hormones in the pill was also thin the lining of the uterus (endometrium), making it less hospitable for a fertilized egg to implant.

When a woman stops taking birth control pills, her body must readjust to the absence of these synthetic hormones. This readjustment process can lead to various physiological changes, including the potential for weight fluctuations, as discussed earlier.

How Long Does Birth Control Last In Your Body?

The duration of birth control’s effects on the body can vary depending on the type of contraceptive method used. Understanding the pharmacokinetics, or the way the body absorbs, distributes, and eliminates the contraceptive hormones, can provide insight into the timeline of weight changes after discontinuing birth control.

Oral Contraceptives (Birth Control Pills)

Combination birth control pills and progestin-only pills (mini-pills) are the most commonly used hormonal contraceptives. When taken as directed, the synthetic hormones in these pills are quickly metabolized and cleared from the body. After stopping the pill, the hormones typically leave the system within a few days, and fertility can return within one to three months, depending on the individual.

Injectable Contraceptives

Injectable contraceptives, such as Depo-Provera, are administered every 12 weeks and provide contraceptive protection for approximately 12-14 weeks. Once the injection wears off, it can take several months (on average 9 months) for fertility to fully return to pre-contraceptive levels.

Intrauterine Devices (IUDs)

Hormonal IUDs, such as Mirena and Liletta, can provide contraceptive protection for 3-6 years, depending on the brand. Once the IUD is removed, fertility can return within a week. Non-hormonal copper IUDs, on the other hand, can prevent pregnancy for up to 12 years, and fertility also resumes within a week of removal.


Contraceptive implants[Source: Cleveland Clinic], like Nexplanon, are small rods inserted under the skin of the upper arm and can provide contraceptive protection for up to 5 years. Once the implant is removed, fertility typically returns within a week.

The Science Behind Post-Contraceptive Weight Fluctuations

The complex interplay of hormonal, metabolic, and physiological factors contributes to the potential for weight changes after stopping birth control. Understanding the underlying mechanisms can provide insights into the management of post-birth control weight fluctuations.

Hormonal Regulation

When a woman discontinues hormonal birth control, her body must readjust to the absence of synthetic estrogen and progestin. This shift can lead to fluctuations in the levels of natural hormones, such as testosterone, estrogen, and progesterone, which can impact various bodily functions, including metabolism, appetite, and water retention.

For example, the return of natural ovulation and the menstrual cycle can cause cyclical changes in hormone levels, which may contribute to weight fluctuations, particularly around the time of the menstrual period.

Metabolic Adaptations

Some research suggests that certain hormonal contraceptives, such as combination birth control pills, may slightly lower the resting metabolic rate (RMR) in some women[Source: Science Direct]. The RMR is the number of calories the body burns at rest, and a lower RMR can potentially lead to weight gain if dietary and exercise habits remain unchanged.

When women discontinue these contraceptives, their RMR may return to pre-contraceptive levels, which can result in a slight increase in calorie expenditure. However, the magnitude of this change and its impact on weight can vary significantly among individuals.

Appetite And Cravings

The hormonal shifts associated with stopping birth control can also influence appetite and food cravings. Some women report an increase in hunger and a stronger desire for calorie-dense foods, such as those high in carbohydrates or fats, after discontinuing hormonal contraception. This change in appetite and craving patterns can contribute to an increase in caloric intake, potentially leading to weight gain.

Water Retention

Hormonal birth control, particularly those containing estrogen, can sometimes cause water retention, leading to temporary weight gain. When the contraceptive is discontinued, the body may shed this excess water, potentially resulting in a slight weight loss.

Strategies To Manage Weight After Discontinuing Birth Control

Navigating the transition after stopping birth control can be challenging, but there are several evidence-based strategies that can help manage weight changes and support overall health during this period:

Maintain A Balanced Diet

Focus on consuming a nutrient-dense, whole-food-based diet that is rich in fruits, vegetables, lean proteins, whole grains, and healthy fats. Avoid processed and high-calorie foods that can contribute to weight gain. Ensure adequate hydration by drinking plenty of water.

Engage In Regular Exercise

Incorporate a combination of aerobic activities, such as brisk walking, jogging, or swimming, along with strength training exercises to help boost metabolism and maintain muscle mass. Aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week.

Consider Supplements

Supplements, such as vitamin D, may be beneficial for some individuals after stopping birth control, as hormonal contraceptives can sometimes deplete certain nutrient levels. Consult a healthcare provider to determine if supplementation is appropriate for your needs.

Manage Stress

Elevated stress levels can contribute to weight gain by disrupting hormonal balance and increasing cortisol production. Practice stress-reducing techniques, such as meditation, yoga, or deep breathing exercises, to help maintain overall well-being.

Track Your Cycle And Weight

Closely monitor your menstrual cycle and any weight fluctuations. Keep a record of your weight, symptoms, and any changes in your cycle to help identify patterns and make informed decisions about your health.
