The birth control arm implant, a small rod inserted under the skin in the upper arm, is a highly effective and long-lasting method of contraception. However, concerns have arisen regarding its potential impact on weight gain. This blog post aims to delve into the evidence and explore the question: does birth control arm implant cause weight gain?
Understanding the Birth Control Arm Implant

Progestin, the hormone released by the birth control arm implant, has been linked to weight gain in some studies. Progestin can increase appetite and fluid retention, which may contribute to weight gain.
