Can an IUD Cause Weight Gain? Understanding the Myths and Facts


An intrauterine device, or IUD, is a popular form of long-acting birth control that is inserted into the uterus. While IUDs are highly effective in preventing pregnancy, some women express concerns about weight gain as a potential side effect. This article aims to explore the link between IUD use and weight gain, drawing on scientific research, personal experiences, and expert opinions to provide readers with a comprehensive understanding of the issue.

Research-Based Article

Recent studies on the relationship between IUD use and weight gain have yielded conflicting results. Some studies suggest that certain types of hormonal IUDs, such as Mirena and Skyla, may increase body weight, while others found no significant association between IUD use and weight gain. However, it is important to note that the studies have some limitations, such as small sample sizes and short follow-up periods.

The underlying mechanisms through which IUDs may influence weight gain are not entirely clear, but some theories have been proposed. Hormonal changes triggered by IUDs may affect appetite, metabolism, and fat storage, leading to weight gain. Inflammation caused by the insertion process or infection may also contribute to weight gain. Additionally, the stress and anxiety associated with using a new contraceptive method may indirectly lead to increased food intake and weight gain.

Personal Experience

As someone who has used an IUD and experienced weight gain, I can empathize with women who have similar concerns. In my case, I noticed a steady increase in my weight after getting the Mirena IUD inserted. While I initially attributed the weight gain to other factors, such as stress and diet, I eventually realized that the IUD might be a contributing factor. The impact of weight gain on my self-esteem and body image was significant, and I struggled to find effective strategies to manage it.

Eventually, I sought professional advice from my gynecologist and a nutritionist. They helped me understand the possible mechanisms underlying IUD-related weight gain and recommended lifestyle changes to mitigate it. For example, I started incorporating more physical activity into my daily routine, tracking my food intake, and practicing stress-reducing techniques such as mindfulness meditation and yoga.

Combining Medical Experts’ Perspectives

To get a more comprehensive picture of the IUD-weight gain link, I consulted with medical experts such as gynecologists and nutritionists. While they had different opinions on the matter, they generally agreed that the evidence is inconclusive and that individual factors such as genetics, lifestyle, and pre-existing health conditions may influence the outcomes. Some experts recommended monitoring weight regularly, adopting a healthy diet and exercise regimen, and seeking professional advice if there was significant weight gain.


To gain more insight into women’s experiences with IUDs and weight gain, I conducted interviews with several women who had used IUDs. While their stories varied, there were common threads in their experiences. Some reported feeling frustrated and embarrassed by the weight gain, while others found it relatively manageable. Most emphasized the importance of seeking professional advice and support from their healthcare providers.

Debunking Myths

There are many myths and misconceptions about IUDs and weight gain that can cause unnecessary anxiety and confusion. For example, some people believe that all IUDs cause weight gain or that weight gain is inevitable with IUD use. However, scientific evidence suggests that the relationship between IUDs and weight gain is complex and variable. Other factors such as diet, exercise, stress levels, and genetics may play a more significant role in determining weight change. It is essential to seek accurate information and dispel false beliefs to make informed decisions about contraceptive options.


While the link between IUDs and weight gain is not conclusive, the issue remains a concern for many women. Through exploring scientific research, personal experiences, and expert opinions, this article aimed to provide readers with a balanced and informative overview of the issue. It is crucial to recognize that the relationship between IUD use and weight gain is not straightforward and may depend on multiple factors. However, monitoring weight, adopting a healthy lifestyle, and seeking professional advice can help mitigate any adverse effects. Finally, it is vital to debunk common myths and misconceptions to make informed choices about contraceptive options.
