Progestin-only contraceptives: effects on weight.

Abstract in brief

• Progestin-only contraceptives are suitable for women who cannot or should not take estrogen and include methods like injectables, intrauterine devices, implants, and oral pills, many of which are long-lasting and cost-effective for preventing pregnancy.
• The review analyzed 22 studies involving over 11,000 women to assess whether using progestin-only contraceptives is linked to changes in body weight, considering both continuous weight changes and specific weight gain or loss, and included various study types like randomized trials and observational studies.
• The findings highlight a diverse set of studies focusing on different contraceptive methods, with outcomes adjusting for confounding factors, attempting to clarify if progestin-only options significantly influence weight differently compared to other contraceptive methods or no contraception at all.]
