When it comes to contraceptives, many people think that they are "emergency contraceptives" after the fact. In fact, there are currently hundreds of oral contraceptives, according to the medicinal properties, the length of effective time and the method of taking, can be divided into short-acting contraceptives, long-acting contraceptives, emergency contraceptives 3 kinds, about the difference between these three can see the following figure.
Emergency contraceptives can only be used as an emergency remedy for contraceptive errors, and should not exceed 1 time per month and 2 to 3 times in a year. The application of long-acting contraceptives and emergency contraceptives is not extensive, short-acting contraceptives are most used in life or treatment, and they are also close friends of obstetrics and gynecology teachers, so today I will talk to you about short-acting contraceptives.
Short-acting combination oral contraceptives are highly effective contraceptives consisting of estrogen and progesterone. Common are a variety of compound preparations composed of norethindrone, levonorgestrel, cyproterone, drospirenone and other progesterones and ethinylestradiol.
In addition to contraception, the health benefits of short-acting combination oral contraceptives in other areas far outweigh the risks.
In addition to contraception, short-acting contraceptives can also help regulate hormone levels
For women, the reproductive endocrine system includes organs such as the ovaries, hypothalamus, and pituitary gland, and is a harmonious and unified whole. The ovaries are the body's "hormone factories" that produce estrogen and progesterone.
If the estrogen and progesterone are too low, it will be fed back to the "superior" hypothalamus and pituitary gland, and the body will begin to produce hormones vigorously.
If the estrogen and progesterone are too high, the "superior" will also receive a signal, thus ordering a reduction in "production".
The essence of oral short-acting contraceptives is synthetically modified hormonal drugs.
The effect of eating short-acting contraceptives can be understood as "importing" some of the main hormones, thus telling the "superior": "Hormones are enough & overdose", so that the superiors order, inhibit the function of the ovaries, so that the industrious production of the ovaries can be recuperated.
Therefore, short-acting contraceptives can not only prevent contraception, but also help to treat gynecological-related diseases.
Other applications other than contraception
1. Functional uterine bleeding, menstrual disorders can quickly stop bleeding and reduce menstrual volume under the joint action of estrogen and progesterone; periodic use of short-acting contraceptives can regularize the menstrual cycle and produce regular withdrawal bleeding.
2. Endometriosis reduces estrogen levels by inhibiting the hypothalamic-pituitary-ovarian axis, directly acting on the ectopic endometrium to make it atrophy, reduce menstrual flow, and improve the symptoms of secondary dysmenorrhea.
3. Primary dysmenorrhea short-acting contraceptive pill reduces menstrual volume and prostaglandin secretion by inhibiting ovulation and endometrial growth, reducing uterine pressure and uterine spasms, thereby treating dysmenorrhea.
4. Short-acting contraceptives for premenstrual syndrome keep the hormone levels of patients relatively stable during the menstrual cycle by inhibiting circulation and endogenous hormones to alleviate related symptoms. Short-acting contraceptives with anti-salt corticosteroid and anti-androgenic effects can significantly improve symptoms.
5. Hyperandrogenemia (acne, hirsutism) progestin with antiandrogenic effect (such as cyproterone, drospirenone, etc.) can alleviate the symptoms of excessive male hormones in women, such as the treatment of acne, seborrheic alopecia, hirsutism, etc.
6. Other short-acting contraceptives also have the effect of preventing a variety of diseases, such as reducing the risk of ovarian cancer, endometrial cancer, colorectal cancer, preventing functional ovarian cysts, and preventing perimenopausal and postmenopausal osteoporosis.
Although short-acting contraceptives are easy to use, they should not be abused, and they should follow the doctor's advice according to their actual situation!
People who do not use short-acting contraceptives should not be used
Although short-acting contraceptives have many benefits and are safe, there are still some people who are not available. According to studies, contraindications to the non-use of short-acting contraceptives include:

Smoking women aged >35 years of age take birth control pills to increase the incidence of cardiovascular disease and should not be taken for a long time. 2. Serious cardiovascular diseases and thrombotic diseases should not be applied, such as hypertension, coronary heart disease, venous embolism, etc. Estrogen has a procoagulant function, increasing the incidence of myocardial infarction and venous embolism. 3. Acute and chronic hepatitis, nephritis, psychosis, severe migraine, diabetes, hyperthyroidism. 4. Malignant tumor and precancerous lesions
