Patient's question:
Medical Description: I have had an IUD for 8 years. A few days ago, I felt a lower abdominal heaviness. A doctor did an ultrasound and said the IUD had shifted. What could be the reason for this?History of Treatment and Effect: The doctor recommended removing the IUD and replacing it, but I haven't had it removed yet.
Desired Help: Should I remove the IUD immediately? The doctor said this type of IUD doesn't need to be removed.
Doctor's answer:
The reasons for IUD displacement are mostly due to improper ring size selection. Intrauterine displacement is often caused by a ring size that is too small, while uterine enlargement often leads to the ring being positioned too low. During uterine muscle contractions, the ring may move downward. In cases of ring malposition, the ring size is usually too large. When the uterus contracts, the ring can damage the endometrium and muscle layer, potentially leading to perforation over time. In summary, as long as the ring size and shape are selected appropriately, uterine muscle movements, including rhythmic contractions caused by sexual activity, will not cause ring displacement. It only affects a small number of patients with improper ring size selection.
