The copper IUD or coil (ParaGard) is a non-hormonal method of birth control. Its main advantage over hormonal methods is that it contains no contraceptive drugs and permits natural ovulatory cycles.
Hormonal IUDs are different from all types of hormonal birth control in that they do not suppress ovulation and can, therefore, permit natural cycling.
Other benefits of hormonal IUDs are that they are convenient and a highly effective method of birth control. They can also dramatically reduce menstrual flow and relieve pain and other symptoms of endometriosis.
Why do antihistamines cause weight gain? And how does hormonal birth control affect metabolism?
In episode eleven of my podcast and Youtube video, I look at how common medications affect metabolism; why birth control that is androgenic is more likely to cause weight gain; and whether natural progesterone causes weight gain or weight loss.
