#HLWDK Daily Health Tips: Do IUDs Cause Smelly Discharge?


Q: Hi doctor. Does a loop cause smelly discharge or just lots of discharge?

A: Intra Uterine Device (IUD) are also known as loop contraceptives. There are two types: the Paragard IUD and the Mirena IUD.

The Paragard IUD is a copper-containing IUD. The copper is poisonous/toxic to sperm and the IUD also prevents implantation of the fertilized egg into the uterus, should fertilization still occur. Paragard can be used during breastfeeding and its removal leads to a quick return of fertility, generally.

The Mirena IUD contains hormones which make the cervical mucous extra thick preventing the sperm from getting to the womb and it also makes the lining of the womb thin such that even if a fertilized egg were to get there, it would not be able to implant on the thin lining of the womb. It also prevents ovulation. Mirena helps reduce the cramping pain of a menstrual period and also reduces bleeding.

Side effects of Paragard include back ache, cramps, severe pain during menstrual period and heavy bleeding etc while Mirena can cause breast tenderness, weight gain, irregular menstrual cycles etc Both IUDs can also be expelled, spontaneously, that is for no reason.

Although vaginal discharge may get heavier after inserting an IUD, the real danger/warning signs to look out for when you have the IUD on are listed below. If you experience any of these under-listed symptoms, please see your doctor immediately.

  • Severe vaginal bleeding with at least two sanitary towels soaked every hour for 2 or more hours.
  • Smelly vaginal discharge. This could be associated with fever and chills
  • Severe pain in abdomen or pelvis

So, you should see your doctor immediately to check this discharge out.

Have a great night 😀
