Pain, nausea, infection, fainting and undiagnosed pregnancy are all considered side effects of the Essure procedure, explains About.com. A study done in 2014 through the Food and Drug Administration states that the Essure procedure does not appear to produce any long-term side effects.
There are some risks associated with the Essure procedure, according to About.com. For instance, the micro-inserts may become expelled from the fallopian tubes, or the coil implants may not have been placed correctly. The micro-inserts may perforate through the fallopian tube or uterus requiring surgery, or the coil implants may become damaged during other procedures, such as an endometrial biopsy. There is also a small risk that an ectopic pregnancy can occur with this type of tubal ligation.
Women who undergo the Essure procedure during the second half of their menstrual cycle are at greater risk of being pregnant at the time of the procedure, states About.com. It is recommended that women undergo this procedure during the first half of their menstrual cycle. It is also a possibility that the insert may break off, though this is rare. Another rare possibility is that a woman may experience an over-absorption of fluids due to the procedure. In this case, she may experience shortness of breath that must be treated immediately in order to avoid serious complications.
