Many women use a metallic IUD, or a hormonal IUD, to prevent pregnancy. The IUD gives great results in birth control, and it is one of the preferred methods of the majority of women for its many advantages, but can infections occur because of the IUD? And what are the reasons?

We answer that question in this article and know the most common symptoms of ileus.

The contraceptive coil

It is a long-acting contraceptive, a T-shaped device, made of copper or plastic, and some types may contain contraceptive hormones.

The coil is placed in the uterus, which leads to an increase in the thickness of vaginal secretions after the insertion of the coil, as well as cervical secretions, in order to impede the arrival of the sperm to fertilize the egg, and its implantation in the lining of the uterus changes the lining, making it difficult to implant the egg inside.

IUD damage

The coil is considered one of the safest methods for women, as side effects affect a small percentage of IUD users, and the matter varies depending on the type of IUD used and the health history of the woman, but it rarely causes serious complications. We list the most common damages of the coil:

  • Irregular bleeding from the vagina for several months between
  • Absence of menstruation, irregularity, or change in the number of days with little or increased menstrual blood.
  • Symptoms of premenstrual syndrome are nausea, breast tenderness, and headache.
  • The coil falls out of its place: It occurs in about 3% of women, and the woman has to go to the doctor to have it reinstalled.
  • Uterine perforation: In rare cases, the IUD may perforate the uterine wall, leading to bleeding and infection, and inflammation due to the IUD.
  • Pelvic inflammatory disease (inflammation of one of the reproductive organs located within the woman’s pelvic area).
  • Feeling strong cramps or cramps that resemble period cramps. Especially in the early days of IUD insertion.
  • Fainting, the woman may lose consciousness or become dizzy once the IUD is inserted.
  • : Fluid-filled cysts form on the ovaries, which soon disappear within 3 months.
  • ectopic pregnancy
  • Pregnancy: Pregnancy rates with IUDs drop very low until they reach 1%, but when they occur, they may cause the following complications:

Causes of iridocyclitis

The coil itself does not cause any types of infection or inflammation, but the infection of the vagina returns after the insertion of the coil for the following reasons:

  • The insertion of the coil spreads infections that are already inside the vagina, such as infection with sexually transmitted diseases, as in chlamydia and gonorrhea, so it is recommended to conduct a test before insertion, to prevent the spread of IUD infections.
  • As it enters the uterus, the IUD pushes bacteria that are naturally present in the vagina, causing infection and inflammation of the genitals.

Pushing bacteria too deep leads to pelvic inflammatory disease (PID), an infection of the uterus, fallopian tubes, or ovaries. Pelvic inflammation is the most serious complication of IUDs.

The incidence of pelvic inflammatory disease among women who use IUDs is 3 to 9 times higher than others, especially during the first 20 days after inserting the IUD, and the chances of risk decrease after several weeks. (2)(4)

Symptoms of IUD infections

Women are recommended to go to the doctor if they notice the following symptoms of IUD infections, which indicate the occurrence of infection:

  1. lower abdominal pain
  2. A foul-smelling vaginal discharge.
  3. Pain when urinating.
  4. Fever and high temperature.
  5. Pain during intercourse.
  6. jerk;
  7. heavy bleeding (2)(3)


The IUD has many advantages that are suitable for women, as it can be used for long years that may reach 10 years, and it can be installed at any time during the menstrual cycle, in addition to its effectiveness of up to 99%, but despite that, a woman may develop IUD infection after its installation and be exposed to a number of Complications, so it is recommended to choose the appropriate contraceptive method by consulting a specialist.
