Final answer:
Combination contraceptives can lead to increased risks of stroke or heart attack, blood clots, various cancers, and gall bladder disease, with potential development of depression or dementia.
Step-by-step explanation:
The side effects of combination contraceptives include a range of potential health risks. Four noted negative side effects are an increased risk of stroke or heart attack, the formation of blood clots, an elevated risk of various types of cancer (such as breast, ovarian, and endometrial cancer), and gall bladder disease. Additionally, there may be an increased likelihood of developing conditions like depression or dementia.
All methods of birth control carry potential side effects; however, health professionals acknowledge that the health risks associated with pregnancy can be higher than those related to contraception. When selecting a method, it's important to have a discussion with a healthcare provider to determine the best option for one's individual health needs.
