Does an IUD Cause Weight Gain? Separating Fact from Fiction


When it comes to birth control methods, one of the most popular options is the intrauterine device (IUD). However, there are many misconceptions about IUDs, including the idea that they cause weight gain. In this article, we will examine the truth behind this commonly held belief and provide an evidence-based analysis on whether or not an IUD causes weight gain. We will also explore the various types of birth control, their potential side effects, and draw a conclusion about the use of IUDs as a birth control method.

Busting the Myth: The Truth About IUDs and Weight Gain

First, it is important to understand what an IUD is and how it works. An IUD is a small, T-shaped device that is inserted into the uterus to prevent pregnancy. There are two types of IUDs – hormonal and non-hormonal – each with their own benefits and potential side effects.

One of the most common concerns about IUDs is their potential to cause weight gain. However, studies have found no significant correlation between IUD use and weight gain. In fact, one study published in the American Journal of Obstetrics and Gynecology found that women who used hormonal IUDs had a slight decrease in body weight over time.

Does Your Birth Control Really Make You Gain Weight? An Evidence-Based Look

Weight gain is often cited as a side effect of several birth control methods, including the pill, the patch, and the implant. However, the research on this topic is mixed. Some studies suggest that hormonal birth control can lead to weight gain, while others find no significant correlation.

It is also important to note that not all types of birth control are created equal. For example, the Depo-Provera shot has been linked to more significant weight gain than other methods.

When it comes to IUDs specifically, the evidence indicates that weight gain is not a significant side effect. This is likely due to the fact that the hormones in an IUD are localized to the uterus, rather than being released throughout the body.

IUDs and Weight Gain: Separating Fact from Fiction

Despite the evidence, there are still many misconceptions about IUDs and weight gain. Some people believe that their IUD is causing them to gain weight, when in reality the weight gain may be due to other factors. For example, changes in diet, exercise habits, or stress levels can all contribute to weight gain.

It is also worth noting that weight gain is a subjective experience. Some women may notice a small increase in weight after getting an IUD, while others may not experience any changes at all.

Weight Gain and IUDs: Real Stories from Real Women

While the research provides us with valuable insights, it is also important to consider the real-life experiences of women who have used IUDs. We spoke to several women about their experiences with IUDs and weight gain.

Many of the women we spoke to did not experience any significant weight gain after getting an IUD. Some even reported losing weight over time. Others did notice a small increase in weight, but attributed it to changes in their diet or exercise routine.

It is clear that weight changes are not a universal experience for those who use IUDs. Therefore, it is important to approach the issue of weight gain and IUDs on a case-by-case basis.

The Pros and Cons of IUDs: Weight Gain as a Possible Side Effect

Like any birth control method, IUDs come with both benefits and potential side effects. The benefits of an IUD include its high effectiveness rate, long-term use, and the fact that it does not require daily maintenance.

As for side effects, weight gain is only one potential issue. Other side effects may include cramping, irregular bleeding, and even perforation of the uterus in rare cases.

When it comes to weight gain specifically, it is important to note that it is not a major side effect of IUD use. While some users may experience a slight increase in weight, this is not a universal side effect.


In conclusion, the myth that IUDs cause weight gain is not supported by the evidence. While weight gain is a potential side effect of some birth control methods, it is not a significant concern for those using an IUD. It is important for women to discuss their concerns with their doctor and choose the birth control method that is best suited for their individual needs.
