Does the Mirena coil cause weight gain?

The Mirena coil does not cause weight gain, according to WebMD. This is one of the advantages of choosing it over other contraceptive methods.

In addition to no weight gain, other advantages of using the Mirena coil include:

• It can reduce bleeding by 90 percent after a few months of using it
• It alleviates menstrual cramps
• There is evidence to suggest it alleviates endometriosis symptoms
• Reduced risk of ectopic pregnancy
• It is a long acting contraceptive that does not require frequent changes

Women considering the Mirena coil should discuss the benefits and risks with a health care provider. There is a small risk of expulsion and perforation, although such incidences are rare.
