Final answer:
For a patient with an eating disorder, the least recommended birth control medications are normally those containing both estrogen and progestin, such as the Ortho Evra patch, Yaz, and Ortho-tri-cyclin, due to heightened risks of blood clots and weight gain. Depo-Provera may be safer in terms of blood clot risk but still requires careful consideration.
Step-by-step explanation:
The birth control medications that are least recommended for a patient with a documented eating disorder would depend on the specific condition and any accompanying health risks or complications. Hormonal contraceptives that contain both estrogen and progestin, like Ortho Evra (the transdermal contraceptive patch), Yaz, and Ortho-tri-cyclin, could potentially exacerbate health risks due to their associated side effects, which include blood clots and weight gain. Since eating disorders like anorexia nervosa often lead to electrolyte imbalances and bulimia nervosa to complications that may increase the risk of blood clots, these medications might not be recommended. In contrast, the Depo-Provera shot, which contains only progestin, does not increase the risk of blood clots but may still be of concern for weight changes. It is crucial for a patient with an eating disorder to discuss contraceptive options with their healthcare provider to ensure the best and safest choice.
