Clinical Question

Do progestin-only contraceptives cause weight gain?

Evidence-Based Answer

There is little evidence that progestin-only contraceptives cause weight gain; in this review, mean weight gain was less than 2 kg (4.4 lb) for most studies up to 12 months. (Strength of Recommendation: B, based on inconsistent or limited-quality patient-oriented evidence.)

Practice Pointers

More than 99% of all U.S. women 15 to 44 years of age who are or have been sexually active have used some form of contraception. Of those who use contraception, nearly one-fourth have tried depot medroxyprogesterone acetate (DMPA; Depo-Provera). The most common reason given for discontinuation of DMPA was weight gain.1 This Cochrane review examined 16 studies on various forms of progestin-only contraceptives and their association with weight gain. The data from these studies were too varied to be combined for meta-analysis. Most of the studies examined DMPA, but others looked at progestin-only implants, oral contraceptives, and intrauterine devices (IUDs). Only one study examined weight change in women taking different types of oral progestin-only contraceptives. The mean weight change in each group was small.

Ten studies examined weight gain in women using DMPA.
