Warning to women using Oral Contraceptives (Birth Control Pills):More than 80 million women worldwide take "the pill" to prevent pregnancy. Typical failure rates among pill users are as high as 12% to 20% in some surveys. Other factors have been shown to increase the risk of pill failure: smoking, diarrhea and/or vomiting drug interactions, systemic illness, psychological stress, menstrual disturbances. CONCLUSION: BC Pills may not be an effective method after the Mini-Gastric Bypass until those factors have resolved. An unplanned pregnancy can be one of life's most difficult experiences. Thoughts and feelings are often confusing. It can be hard to know what to do.

So CONCLUSION: BC Pills may not be an effective method of Birth Control after the operation until those factors have resolved. N Z Med J 1989 Nov 8;102(879):575-7 Pregnancies in reliable pill takers. Sparrow MJ Parkview Clinic, Wellington Hospital. This study is an extension of a previous study on oral contraceptive pill method failure in reliable pill takers. It documents 137 cases which presented during the 3 year period from December 1985 to December 1988. The most important new finding is that smoking is a significant risk factor in failure on the combined pill (67% were smokers, n = 118), but not on the progestagen-only pill, although the numbers in the latter group were small (n = 19). Diarrhea and/or vomiting (46%) and drug interactions (33%) are confirmed as important predisposing factors. Systemic illness and/or severe psychological stress may also affect pill utilization and such factors were found in 47%. Menstrual disturbances were found in 32% of women on the combined pill and 68% of these were smokers. Multiple factors were present in most cases (79%). Repeat failures occurred in 25% |
