The copper intrauterine device (IUD) is a popular and effective form of contraception used by millions of women worldwide. However, there have been claims and concerns raised over whether copper IUDs can cause weight gain. In this article, we will explore and scientifically explain the possible relationship between copper IUDs and weight gain. We will also address misconceptions and misconstrued information around the topic, share personal experiences, and provide tips for managing weight while using copper IUDs. Additionally, we will discuss alternative contraceptive choices that consider weight gain as a factor.

Scientifically Explaining the Connection between Copper IUD and Weight Gain

While there have been research studies linking copper IUDs with weight gain, the scientific evidence remains inconclusive. No definitive causal mechanism has been conclusively established, and theories based on the available data differ.

On the one hand, some copper IUD users have reported experiencing weight gain after insertion, while others have not. Such experiences were neither found to be unique to women modifying their menstrual cycles. Weight gain has been observed with the cessation of contraceptives that included hormonal effects, such as the pill or an IUD that includes hormones. Also, scientific studies have suggested that copper IUDs have no effect on weight gain.

Thus, it is vital to understand that there is unlikely to be a simple, direct causation linking copper IUD use with weight gain. The factors that might affect it are unique to an individual’s particular health profile, including lifestyle habits, age, and underlying risk factors.

Copper IUD – Types, Benefits, and Side Effects, including Weight Gain

Copper IUDs are small, T-shaped devices inserted into the uterus to prevent pregnancy for up to ten years. The copper ions released by the device kill sperm and prevent them from fertilizing the egg. There are currently four FDA-approved copper IUDs in the United States, including Paragard and T-Safe.

Copper IUDs are highly effective, with a failure rate of less than 1%. They can be easily removed, have no hormonal effects and can be used by women who cannot or do not want to use hormonal contraceptives.

However, it is worth mentioned that some women have reported experiencing significant side effects such as menstrual cramps, spotting between periods, and heavier periods while using copper IUDs. Additionally, weight gain has also been reported, although the connections are still not clear.

Personal Experiences on Copper IUD – Effects on Weight and other Areas of Health

While anecdotal evidence cannot prove causal relationships, it can provide insights into personal experiences with copper IUD use. Weight gain is a common concern for most women using copper IUDs, and personal experiences show that they contribute to weight gain for some women.

Women’s experiences with copper IUD vary widely, with some experiencing a negligible weight change or no change at all. Others may experience substantial weight fluctuations. Personal experiences also indicate that some women experience accompanying side effects such as irregular periods, increased cramping, and heavier bleeding. It is essential to reiterate that such results could vary significantly depending on an individual’s health profile and lifestyle choices.

Copper IUD vs. Hormonal Contraceptives – Impact on Weight Gain

Comparing hormonal contraceptives and copper IUDs’ effects on weight gain is essential since they are the most common choices for contraception. While copper IUDs may cause irregular periods or heavier bleeding, the device itself does not contain hormones. At the same time, hormonal contraceptives, including the pill and hormonal IUDs, do impart hormones that modify the menstrual cycles and affect estrogen levels in the body. The hormones have been found to cause water retention in women, which can be confused with weight gain.

Of the various viable contraceptive options, it seems that hormonal contraceptives can cause more significant weight changes, such as an increase in body fat and appetite. A 2019 systematic review and meta-analysis of twelve studies comparing hormonal contraceptives and the non-hormonal copper IUD found that there were no differences in weight changes between hormonal IUDs and copper IUDs. Still, hormonal contraceptives did contribute to significant weight changes in women.

In light of such findings, more women concerned about weight gain may consider opting for non-hormonal forms of contraception such as the copper IUD.

Managing Weight While on Copper IUD – Tips and Strategies

Women who have experienced weight gain while using copper IUDs may be keen to explore strategies to manage such changes. While no definitive method works for everyone, the following tips and strategies can prove useful and effective:

  • Regular exercise
  • Reduce or manage stress levels
  • Healthy diet with enough protein, fiber, and healthy fats
  • Drink enough water to stay hydrated
  • Manage sleep pattern, ensuring enough rest, and good sleep quality
  • Limit processed and sugary foods, which can cause water retention and bloating

It is important to note that these strategies should not be used as a substitute for medical advice, diagnosis, or treatment. Consulting with a healthcare professional can provide more personalized tips and strategies concerning calorie intake and safe exercise patterns.

Copper IUD – Misconceptions and Facts on Weight Gain

It is crucial to address common misconceptions and provide accurate information on the topic of copper IUDs and weight gain. These are:

  • Myth: Copper IUD use leads to copper poisoning
  • Fact: Although copper IUDs release copper ions into the uterus, the amount is insufficient to cause copper poisoning. Individuals who are allergic or intolerant to copper, however, may experience side effects that are unique to their situation and should consult with their health care provider. The copper IUDs are safe and approved by major health authorities around the world, including the FDA in the United States.

  • Myth: Copper IUDs cause weight gain by increasing appetite
  • Fact: While copper IUDs’ usage may cause some changes in a woman’s cycle, they are not known to affect appetite, calorie intake, or fat metabolism.

  • Myth: Weight gain for copper IUD users is permanent
  • Fact: While initial reports of weight gain may be unsettling, it is something that can often be managed using the tips and strategies mentioned earlier. Weight gain is often reversible, and a person’s weight can stabilize after a few months of adjustments.

Alternatives to Copper IUD – Exploring the Weight Gain Factor

Contraceptive methods that cause fewer side effects in terms of weight changes include the following:

  • Barrier methods, such as condoms
  • Cervical caps or diaphragms
  • Fertility awareness methods
  • Progestogen-only contraception

It is essential to note that every method carries its own risks and benefits. Women seeking an alternative to copper IUDs should consult their health care provider to determine which form of contraception would be most suitable based on their individual situation, health needs, and lifestyle.


The relationship between copper IUD use and weight gain is an issue not yet fully understood or concluded. While some women may experience weight gain while using copper IUDs, these findings cannot prove a causal connection. Personal experiences and scientific studies do suggest that hormonal contraceptives, on the other hand, can cause weight gain more commonly. Individuals seeking non-hormonal forms of contraception may consider copper IUDs. However, it is essential to consider that weight gain is one of the many possible side effects that could differ depending on the individual. With expert guidance, women can make an informed decision, manage any potential side effect, and minimize any harm to their health.
