Ehkäisypillerit

Ehkäisypillerit, commonly known as birth control pills, are a form of hormonal contraception taken orally. They contain synthetic versions of hormones, primarily estrogen and progestin, which work by preventing ovulation, thickening cervical mucus to block sperm, and thinning the uterine lining to make implantation less likely.

There are two main types of birth control pills: combined pills and progestin-only pills (mini-pills). Combined pills contain both estrogen and progestin, while progestin-only pills contain only progestin. Combined pills are the most common type and are taken for 21 days followed by a 7-day break or in a continuous regimen. Progestin-only pills are typically taken daily without a break.

Ehkäisypillerit are highly effective when used correctly, with a failure rate of less than 1% when used perfectly. However, typical use failure rates are higher due to missed pills or other factors. They are a reversible method of contraception, meaning fertility returns after discontinuing use.

While generally safe and effective, birth control pills can have side effects, which vary among individuals and pill types. Common side effects include nausea, breast tenderness, headaches, and mood changes. More serious but rare side effects can include blood clots, stroke, and heart attack, particularly in individuals with certain risk factors. It is important to consult a healthcare provider to determine if birth control pills are a suitable option and to discuss any potential risks or concerns. They can also help choose the most appropriate type of pill for an individual's needs and medical history.
