Are Low-Dose Birth Control Pills Right for You?
Birth control pills have been the best method for stopping pregnancy in these United States since they did approve by the U.S. Food & Drug Administration (FDA) in 1960. They’re effective, readily accessible, and inexpensive.
Low-dose tablets include 10 to 30 micrograms (mcg) of this hormone estrogen. Pills that just have 10 mcg of estrogen remain listed as ultra-low-dose. Estrogen is in most delivery control pills, and it’s linked to an enhanced risk of health difficulties, such as blood clots and stroke.
The exception is the minipill. It’s possible in only one dose that contains 35 mcg of progestin.
Birth control pills that aren’t low doses may receive up to 50 or so mcg of estrogen. These are infrequently used today, while lower doses are available. By contrast, the first pill to enter the store contained 150 mcg of estrogenTrusted Source.
How birth control pills work
The hormones estrogen and progesterone signal your body to produce eggs and plan for pregnancy.
If a sperm doesn’t fertilize the egg, the levels like these hormones fall steeply. In answer, your uterus sheds the lining that had grown up. This lining is discarded during your period.
Birth control pills include either a combination of artificial estrogen and synthetic progesterone or artificial progesterone only. This manmade variant of progesterone is also recognized as progestin.
Estrogen plus progestin works in many ways to prevent pregnancy. Both work to stop the pituitary gland from creating hormones that trigger ovulation.
Progestin also reinforces your cervical mucus, making it harder for sperm to reach any delivered eggs. Progestin thins that uterine lining as well. This makes it more difficult for an egg to embed there if the sperm fertilizes it.
