Progestin-only pills (POPs) contain low doses of progestin and no estrogen. They prevent pregnancy by thickening the cervical mucus and inhibiting ovulation. There are very limited data on weight changes in this group of contraceptives. In a large randomized trial comparing two types of POPs, no significant weight changes were reported and no difference in weight gain was found between the two types of POPs included after 13 cycles of use.
