Have you unintentionally gained weight over the years? If you have an intrauterine device (IUD) for birth control, you may wonder if it’s contributing to your weight gain.
However, your weight gain probably has more to do with the natural aging process and lifestyle choices rather than your birth control.
An IUD is one form of contraceptive used by people who menstruate. It’s a small device that your doctor inserts into your uterus. It’s one of the most effective methods of reversible birth control.
Two forms of IUDs are available:
The copper IUD (ParaGard) is a plastic, T-shaped device with copper wire wrapped around it. It creates an inflammatory reaction in your uterus, which is toxic to sperm. This helps prevent pregnancy. The device lasts up to 10 years before you need to replace it.
The copper IUD may cause side effects, such as:
- painful sex
- bleeding between periods
- heavy bleeding during periods
- severe menstrual pains
- vaginal discharge
Weight gain isn’t a listed side effect of the copper IUD.
Hormonal IUDs such as Mirena and Skyla are plastic T-shaped devices that release the hormone progestin into your uterus.
This thickens your cervical mucus to prevent sperm from reaching and fertilizing your eggs. The hormone also thins your uterine lining and helps prevent your eggs from being released.
The Skyla IUD lasts up to 3 years before you need to replace it, and the Mirena IUD can last for up to 5 years before it needs to be replaced.
Hormonal IUDs may cause side effects, such as changes in your menstrual bleeding and missed periods. Other side effects include:
Hormonal IUDs also list weight gain as a possible side effect.
One 2020 study compared weight gain with the hormonal IUD, the copper IUD, and the birth control implant among a large group of racially diverse women. The hormonal IUD showed that hormonal IUD users gained about 0.72 kg (about 1.59 lbs) on average after 12 months.
This suggests that hormonal IUDs could contribute to low levels of weight gain. It should be noted that weight gain can have many causes and that more research needs to be done.
If you choose to use an IUD, your doctor will have to insert it. Contact your doctor immediately if you experience any side effects after the IUD is inserted.
IUDs don’t prevent the spread of sexually transmitted infections (STIs). You should use other barrier methods, such as condoms, to protect yourself and your partner from STIs.
It’s commonly assumed that using certain contraception methods leads to weight gain. However, studies indicate that most people tend to gain weight during their reproductive years, regardless of their chosen birth control methods.

If you think you’ve gained weight because of your hormonal contraceptive, talk to your doctor. There are many forms of contraceptives available.
