Contraceptive Pill – Weight Gain

Patient: Hi,I’ve been on the pill for about 3 months now and I’ve noticed that I’ve put on weight in places that I wouldn’t usually e.g. my back and face? Also my boobs, bum, thighs and even stomach have become bigger. I train 8 times a week for 2 hours for swimming, plus 2 gym sessions and eat relatively healthy. I’m 15 and Mum and I don’t think it’s normal for me to be putting on this weight as I am really fit and most of my body mass is made up of muscle as you can imagine. So is the pill the cause of this extra weight?Thanks so much,
