Today there is a fairly large selectionvarious contraceptives, a significant proportion of which are hormonal contraceptives. They are a way to protect against unwanted pregnancy with artificial sex hormones. Choosing a similar tool, you should first consult a gynecologist and specialist - an endocrinologist, since the application of some of them can have quite dangerous consequences for health. The effect of contraceptive tablets is based on the principle of suppression of the natural process of ovulation. It is suppressed by inhibiting the production of its own hormones and causing some changes in the mucous membrane of the uterus. As a result, the uterus becomes denser, preventing the free movement of the spermatozoa that enter it, and its fertilization does not occur. The use of hormonal contraceptives is unsafe for women with increased sensitivity to estrogens and gestagens. Signs of such sensitivity - acne, a strong weight gain during a previous pregnancy, excessive body hair, swelling before menstruation, abundant discharge during the period of ovulation. It is not recommended to use such tablets and women, in whose family thromboembolic diseases and blood clotting disorders were observed. Very carefully, women who suffer from diabetes, cardiovascular diseases, kidney disease, bronchial asthma, multiple sclerosis, epilepsy should use them. Therefore, the choice of a hormonal drug is carried out only after consultation with a gynecologist and endocrinologist, who must first prescribe a survey and carefully study the history of all the diseases transferred and available. Before using contraceptives of this kind, it is necessary to measure the pressure, examine the condition of the mammary glands and liver, perform a cytological analysis of the cervix and donate blood to sugar. A woman who constantly takes hormonal medications needs at least every six months, to visit a gynecologist and undergo an examination. In the event that viral hepatitis has been transferred, oral hormonal contraception can be administered no earlier than six months after the normalization of liver function. Smoking women over the age of thirty who intend to resort to oral contraceptives should first completely quit smoking, since the estrogens contained in such drugs increase the risk of developing thromboembolism. In general, to choose the optimal variant of a hormonal contraceptive you need to visit a gynecologist, an endocrinologist, a mammologist. In addition, it is necessary to donate blood to biochemical analysis, to do an analysis of the hormonal background and ultrasound and to conduct a blood test for clotting. All these measures will help reduce the likelihood of negative side effects when using tablets to a minimum. We advise you to read:
