What Is an IUD?
An IUD is a T-shaped, plastic device implanted into the uterus to prevent pregnancy. There’s only one type of copper IUD, and it’s called ParaGard. A copper wire is coiled around the stem of the device and copper sleeves cover each arm. ParaGard continually releases copper into the uterine lining. The copper is lethal to sperm and helps prevent fertilization.
Other types of IUDs release hormones into the body. These hormones thicken cervical mucus to help prevent sperm from moving towards an egg. All IUDs have a string attached so you can make sure it’s in place. This string also helps your doctor remove the device. If you want to become pregnant, an IUD can be removed any time.
IUDs don’t prevent sexually transmitted diseases (STDs). If you’re at high risk of contracting one, you’ll need to use condoms as well.
How Effective Are IUDs?
IUDs top the list of effective birth control methods with less than one pregnancy per 100 women each year. Once it’s inserted, the ParaGard copper IUD helps prevent pregnancy for up to 10 years. Hormonal IUDs help prevent pregnancy for three to five years.
Side Effects and Risk Factors to Consider
Since a copper IUD has no hormones, the side effects are less severe than those of hormonal IUDs or other forms of hormonal birth control. The side effects can include:
- a backache
- breakthrough bleeding, or bleeding between periods
- vaginal inflammation
- pain during sex
- severe menstrual pain
- heavy periods
- vaginal discharge
In rare cases, an IUD is expelled from the body. This is more likely to happen if any of these apply:
- you’ve never been pregnant
- you have heavy periods and severe menstrual pain
- you’ve expelled an IUD before
- you’re under age 20
- you had the IUD inserted immediately after childbirth or after an abortion in the second trimester
There’s a slight possibility of perforating the wall of the uterus, particularly during placement. If perforation occurs, the IUD should be removed and surgery may be needed. Perforation may cause infection, scarring, or damage to other organs.
Copper IUDs and Weight Gain
Weight gain isn’t listed as a side effect of ParaGard. Anecdotal evidence from women using the device indicates IUDs cause weight gain, but scientific evidence is inconclusive.
Although these studies indicate IUD users experienced weight gain, it’s unclear if the gain was due to the IUD or normal aging and lifestyle factors such as diet and exercise. Removing the IUD didn’t necessarily result in weight loss. More research is needed to put an end to the debate about weight gain and IUDs.
Should You Get an IUD?
Birth control is a personal choice that should be weighed carefully. Most women can safely use a copper IUD, but you should consider other options if you have any of these risk factors:
- uterine abnormalities that interfere with placement
- a pelvic infection
- uterine or cervical cancer
- unexplained vaginal bleeding
- allergies to any components of the IUD
- Wilson’s disease, which causes the accumulation of copper in the brain and other organs
- a high risk of having an STD
- a history of problems with an IUD
Which Birth Control Is Right for You?
A copper IUD is a great option for women who want to avoid hormonal birth control or want the convenience of not having to think about birth control in the long term. When it comes to weight gain, the definitive verdict is still out. Eating a healthy diet and staying active may help reduce your risk of packing on extra pounds. Talk to your doctor if you’re interested in using a copper IUD but are concerned about weight gain.
