Does Birth Control Make You Gain Weight?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.
Weight gain from birth control is possible but not universal, affecting about 20-25% of users. Hormonal contraceptives containing progestin can increase appetite and cause water retention, leading to 1-5 pound weight changes in the first few months. However, multiple studies show that most women maintain stable weight on birth control. The copper IUD causes no hormonal weight changes, while combination pills typically cause less weight fluctuation than progestin-only methods. Individual responses vary significantly based on metabolism, lifestyle, and the specific contraceptive type. Track your weight for the first 3-6 months after starting any new birth control method.
