The Negatives of The Intrauterine System (IUS)

Because the IUS is fitted within the uterus, there remains a risk of rejection by the body and the device has also been known to fall out of the vagina on occasions. This highlights the need for consistent check ups from a doctor. During the first few months of use, a patient may experience irregular bleeding while the IUS adapts to control over periods within the body. The hormone within Mirena can also cause breast tenderness, acne and headaches or mood swings amongst users. As with the IUD device, there remains a risk of damage wall of the womb as the Mirena has been known to perforate or damage this area, sometimes during the fitting process itself. If pain is experience in the lower area of the stomach, a doctor should be consulted. As with the fitting of any outside device into the womb, a small risk of infection remains and can be passed on to any partners. The progestogen hormone has also be known to cause cysts around the ovaries which while relatively non threatening, should be assessed and monitored by your doctor at all times. The presence of the progestogen hormone also brings an increased risk of certain cancers in the cervix and ovaries.
