Long-acting Reversible Contraception: The Effective and Appropriate Use of Long-Acting Reversible Contraception

Contraception can be divided into two broad categories: hormonal and nonhormonal. There are two categories of hormonal contraception: combined oestrogen and progestogen and progestogen-only. Long-acting reversible contraception (LARC) is defined in this guideline as methods that require administering less than once per cycle or month.

Hormones for birth control in overweight or obese women

Excess body weight has become a health problem around the world. Being overweight or obese may affect how well some birth control methods work to prevent pregnancy. Hormonal birth control includes pills, the skin patch, the vaginal ring, implants, injectables, and hormonal intrauterine contraception (IUC).

Skin patch or vaginal ring compared to pills for birth control

The skin patch and the vaginal (birth canal) ring are two methods of birth control. Both methods contain the hormones estrogen and progestin. The patch is a small, thin, adhesive square that is applied to the skin. The contraceptive vaginal ring is a flexible, lightweight device that is inserted into the vagina. Both methods release drugs like those in birth control pills. These methods could be used more consistently than pills because they do not require a daily dose. This review looked at how well the methods worked to prevent pregnancy, if they caused bleeding problems, if women used them as prescribed, and how safe they were.

Hormone contraceptives and how the body uses carbohydrates in women without diabetes

Hormone contraceptives may change how the body handles carbohydrates (starches and sugars). Changes may include lower ability to use sugar from food and more problems with the body's insulin. Insulin is a hormone that helps the body use sugar. Problems with blood sugar can increase risk for diabetes and heart disease. These issues have been raised mainly with birth control methods that contain the hormone estrogen.
