Modern IUDs have been used for decades to prevent unwanted pregnancy and have been extremely effective at doing so. But they’re not without side effects. With few places to turn, many patients have resorted to TikTok to describe their experiences of painful insertion and removal as well as cramping, changes in menstruation, and mood shifts. But patients don’t have to be left in the dark. If there was more research into how different bodies react to IUDs, there’s a chance patients can get the care they need without as drastic of side effects. On this week’s episode of Well, Now Maya and Kavita talk with Dr. Kavita Nanda, the Director of Medical Research for FHI360, on why there is so little research into IUDs, what we do know about them, and how you or a loved one can prepare for a conversation with your doctor about them.
