Hormonal birth control pills (oral contraceptives) first appeared in the 60s of the last century and in the beginning gave a lot of side effects. But pharmaceutical companies are constantly coming out with new, more sophisticated drugs in this group. Today, they have far fewer side effects, and are considered safe enough.
Of what are composed and how hormonal birth control pills
The composition of oral contraceptives (OC) includes synthetic analogues of female sex hormones estrogen and progesterone. The mechanism of action of hormonal contraceptive tablets based on the fact that a large number of female hormones suppress pituitary gonadotropic hormones that normally stimulate the secretion of female hormones for a large amount of the need for the pituitary hormones decrease. Inhibit the secretion of follicle stimulating hormone (FSH) and luteinizing hormone (LH), the hormones of the pituitary gland. FSH stimulates the maturation of the egg, and LH - out egg from the ovary (ovulation) and the maturation of the corpus luteum, which occurs on the site of the ruptured follicle and produces progesterone
Progesterone - norm and pathology
Just pack 21 tablets are usually OK, you want to take every day at the same time for three weeks - it supports the menstrual cycle. Next week is a break in reception OK - open hormonal support causes rejection of the mucous membrane of the uterus and bleeding menstrualnopodobnoe.
All OK can be divided into two groups: combined OK (they contain two types of female hormones - estrogen and progesterone) and progestin OK or mini-pill (they contain only analogues of progesterone - progestins).
Combined hormonal contraceptive pills
The most effective and safe combination considered OK. They are divided into monophasic, biphasic and three-phase. All tablets monophasic OK dosage of estrogen and progestin the same. They differ according to the type and dose of their component products. It includes a combined monophasic OK regulon, lindinet - 20, Jess, Novinet and others. These QA often used for prevention and treatment of endometriosis
Endometriosis - a serious problem with serious consequences
The combined biphasic OK (eg anteovine) the same amount of estrogen and progestogen the amount varies depending on the phase of the menstrual cycle. They are prescribed for women increased sensitivity to progesterone and its analogues.
The most advanced, reliable, safe and physiologic considered the combined three-phase OK, they doses of both components vary depending on the day of the menstrual cycle
The days of the menstrual cycle: Four phases
OK These include the minimum dose of hormones and are particularly recommended for young girls, women over 40, smokers and overweight women burdened. These drugs (triziston, trikvilar) also nominated for therapeutic purposes in the menstrual cycle.
These tablets contain only synthetic analogs of progesterone. They are prescribed to women who, for whatever reason, estrogens are contraindicated, after 40 years, breastfeeding, smoking. These displays OK for women with increased blood clotting and high blood pressure, as they do not increase the propensity to thrombosis.
The disadvantage of these drugs is their lack of reliability, so today they generally recommend taking only during lactation - OK, you can take these in three to four weeks after birth.
How to take
Independently start taking these pills is not advisable. First, today issued the set of OK, in which the woman can easily get confused and do not take the drug that will suit her best. But most importantly, why you need to see a doctor - a survey to exclude contraindications for receiving OK.
Contraindications OK are malignant tumors of female genitals and mammary glands, increased blood clotting and thrombophlebitis, severe liver disease in violation of its function, bleeding from the genital organs of unknown origin, infectious and inflammatory diseases.
Only after eliminating these contraindications gynecologist prescribe OK.
Modern hormonal birth control pills are very well tolerated, but sometimes they still give side effects such as irritability,
Irritability - you try to control my temper
, Decreased libido, weight gain, edema, allergic reactions. In some cases, can increase blood pressure, worsen cholecystitis.
But the main danger of even the most advanced oral contraceptives (except mini-pill) is thrombosis. These side effects are rare, but may threaten a woman's life, so it's important preliminary examination before prescribing hormonal contraceptive pill.
