Family planning is important to many people. Among the methods available, the copper IUD is a popular, hormone- free, and long-lasting method that can be used for many years. Some people also call it simply 'the IUD'. It's a small device that is placed inside the uterus . So let's take a look at what it is, how it works, who it's suitable for, and everything you need to know about it in detail.

What is a copper loop?

Simply put, the copper IUD is a small T-shaped device made of flexible plastic with a copper wire wrapped around it. Your doctor inserts it into your uterus. The copper ions released from it prevent sperm from fertilizing an egg. It also changes the environment inside the uterus so that a fertilized egg cannot implant. Since it is a non-hormonal method, it is a good option for those who are not suitable for hormonal birth control methods.

The most important thing is that once it's properly inserted, it provides continuous birth control protection for up to 10 years. That means you don't have to take pills every day or get an injection every three months.

Things you need to tell your doctor before having an IUD inserted

Before deciding whether this method is right for you, it's important to talk openly with your doctor about your health. Some health conditions may make using the copper IUD less suitable. Be sure to mention these things in particular:
  • Pregnancy : If you are currently pregnant or suspect you are pregnant.
  • Cancer: If you have breast , uterine, or cervical cancer, or have been treated for it.
  • Infections: If you currently have an infection in the genital area or pelvic area (e.g. PID), or if it occurs frequently.
  • Unexplained bleeding: Abnormal vaginal bleeding for no apparent reason.
  • Uterine shape: Has a doctor told you that your uterus is not shaped normally (e.g., biconuate uterus )? If so, it may be difficult to hold the IUD in place.
  • Copper-related diseases: This is not suitable at all if you have Wilson's disease, which is a condition in which copper accumulates in the body.
  • Allergies : If you have an allergy to copper, barium sulfate, or polyethylene.
  • Previous pregnancies: Have you had an ectopic pregnancy before?
  • Sexual habits: If you have more than one sexual partner, or if your partner has one, it is important to tell your doctor about it. This increases the risk of contracting sexually transmitted diseases and may require reconsideration of the IUD .
  • Breastfeeding: If you are currently breastfeeding your baby, also mention that. This is generally safe for breastfeeding mothers.

Things to be careful about while wearing the loop

After installing the loop, pay attention to these things to make sure it is in place and that you are not having any problems.

Checking the threads

You can check to see if the loop is in place yourself. Once a month, especially after your period , insert clean fingers into your vagina and check to see if the two threads of the loop hanging near your cervix are caught.
  • Never pull on these strings.
  • If you can't feel the string, if it feels shorter or longer than usual, or if the plastic part of the IUD gets caught in your hand, it may have slipped out of place. If this happens , call your doctor right away. In the meantime, use another method of birth control, such as a condom, to prevent pregnancy.

There is no protection against sexually transmitted diseases!

This is very important. The copper IUD only prevents pregnancy. It does not protect against sexually transmitted diseases (STDs) such as HIV (AIDS), syphilis, and gonorrhea. Therefore, it is essential to practice safe sex and use condoms if necessary.

Other points

  • Expulsion: Very rarely, especially within the first few months of insertion, the IUD can come out on its own. If this happens, you are at risk of becoming pregnant. So if you notice that the IUD has come out, see a doctor immediately.
  • MRI Scan: If you ever have to undergo an MRI scan, you must tell the medical staff that you have a copper loop inserted.
  • Using Tampons: Using tampons during menstruation will not harm the IUD. It is safe.

What are the possible side effects?

As with any medical procedure, the copper IUD can cause some side effects. Some are normal and will subside over time. But some things require immediate attention.
Side effect Description and what to do
Symptoms that should be reported to your doctor immediately
Allergic reactions Skin rash, severe itching, swelling of the face, lips, tongue or throat, difficulty breathing. These are very rare but are an emergency.
Heavy bleeding Heavy bleeding that soaks more than two sanitary pads in an hour.
Pelvic infection (PID) Fever, severe pain in the abdomen or pelvic area, pain during urination, and vaginal discharge with an unusual odor.
Symptoms of Anemia Excessive bleeding can cause shortness of breath, fainting, extreme fatigue, and paleness.
Pain during sex New or severe pain during intercourse.
Usually does not require medical attention (but tell your doctor if it persists)
Menstrual changesDuring the first few months, you may experience heavy bleeding and cramping during your period. You may also experience spotting between periods. These usually improve after 3-6 months.
Back pain Back pain may occur after the IUD is inserted or during menstruation.

💡 Take-Home Message

  • The copper IUD is a highly effective, hormone-free family planning method that can be used for up to 10 years.
  • This only prevents pregnancy. It does not protect against sexually transmitted diseases, including HIV (AIDS). It is important to use a condom for this.
  • The insertion and removal of the IUD should only be done by a trained doctor or family health worker.
  • It is a good practice to check the threads of the IUD monthly. If you cannot feel the threads, notice a change, or if the IUD comes out, see your doctor immediately.
  • If you experience symptoms such as heavy bleeding, severe abdominal pain, fever, or foul-smelling vaginal discharge, do not ignore it and seek medical advice immediately.
  • If you have any more questions about this, don't be afraid to talk to your doctor and get everything clarified.
