Coil (IUD) Insertion
An intrauterine device, or coil, is a small device placed inside the cavity of the womb. It provides long-acting contraception that requires nothing on a daily basis, and its effect ends as soon as it is removed.
Two types
- Copper coil: contains no hormone and does not change the menstrual pattern; bleeding may increase in the first months
- Hormone-releasing system: markedly reduces menstrual bleeding and is also used as a treatment for heavy periods
Before insertion
Examination and ultrasound assess the structure of the uterus; pregnancy and infection are excluded, and infection screening is carried out where indicated.
The last days of a period, or the days immediately after it ends, are preferred, as the cervix admits the device more readily at that time.
The procedure
Insertion takes a few minutes. You may feel cramping similar to period pain; a painkiller taken an hour beforehand reduces this. A general anaesthetic is not required.
You rest briefly afterwards and return to normal activity the same day.
Afterwards
- Spotting and cramping in the first weeks are common and settle with time
- The first check is usually after the next period
- An annual check is sufficient thereafter
- You can be taught to check the threads yourself
When to seek help without delay
- Fever and offensive discharge
- Severe, persistent abdominal pain
- A missed period (possible pregnancy)
- Threads that cannot be felt, or noticing that the device has been expelled
