CDC has contraception advice for some ill women

In May, U.S. health officials for the first time released contraception safety guidelines for more than 1 million women who have had weight-loss surgery or have certain medical conditions. The Centers for Disease Control and Prevention guidelines says it's safe for women with medical conditions to use most contraceptives.

But the CDC issued some warnings, including some concerning birth control pills, the most popular form of contraception for American women. The pill may be less effective for women who have had one kind of weight-loss surgery because the procedure may leave them less able to absorb the active ingredient. Another warning: Some women with inflammatory bowel disease have a higher risk of blood clots. Those women generally should not use the estrogen-containing form of the pill, which may further increase their risk.

The CDC borrowed from international guidelines, but also wrote new advice for women with certain conditions more common in the United States, such as inflammatory bowel disease and rheumatoid arthritis.
