Does hormonal coil (IUS) cause weight gaining?

I’m 44 with recently diagnosed PCOS and endometriosis which is why my specialist told me to try the Mirena to lighten the lining of my uterus and help with my awful periods. I had to go off of the pill at 40 and suffered for 2 years while debating what to do. I got the mirena in at 42 and have had it 2.5 years now. I do get pelvic pain and cramping twice a month for a few days randomly and feel like I can tell which ovary is active but it is still better than dealing with the bleeding and irregular periods I had previously. My periods are non existant apart from spotting for a few days but not enough to even merit wearing a liner! Sex drive is definitely lower and dryness comes and goes as well but breasts have grown which I’m not upset about! I’m leaving it for another 2 years then will decide if I should opt for a hysterectomy.

I had an awful time getting it in and out. I have never given birth, which can make it worse. The cramping pain was so bad, I vomited when getting it in and they had to use arterial forceps to remove it as the strings got lost (ouch). My skin was better and my moods were more stable. My period also stopped which saved a lot of money. I gained a lot of weight, though and the amount and intensity of my migraines increased a lot. I also had terrible cramping pain despite no periods, which was linked to PCOS. I haven’t had any symptoms since getting it removed 2 years ago.

Overall helped to regulate my periods, but also had significant side effects on my food intake/weight and on my energy levels.
