Symptoms of a lack of progesterone - is, above all, various kinds of menstrual disorders, since progesterone provides offensive and proper development of its second half. The lack of progesterone is often associated with excess female hormone estrogen. During pregnancy, progesterone prevents miscarriage.
The function of progesterone in a woman's body
Progesterone - a female sex hormone that is produced in the second half of the menstrual cycle (MC). Progesterone secretion begins after the formation of on-site ruptured follicle glands of internal secretion of the corpus luteum. Therefore, the formation of progesterone is directly related to the secretion of other female sex hormones - estrogen, as estrogens in the first half of the MP promote oocyte maturation, follicular rupture, where it matures and output egg from the ovary (ovulation).
If little estrogen and the egg is not ripe, it can not break the follicle, so ovulation does not occur, the corpus luteum does not form and progesterone is not synthesized. If too much estrogen, the first half is prolonged MC, progesterone secretion is suppressed.
By the end of the menstrual cycle, if pregnancy does not occur, the amount of progesterone drops abruptly.
This causes rejection of the functional layer of the mucous membrane of the uterus and removal of the uterus through active contractions of smooth muscles.
Progesterone also affects the cyclic changes in the uterine mucosa. Under the influence of progesterone in the second half MC begin to function gland mucosa of the uterus, there are changes in the fallopian tubes, which help to move the egg toward the uterus. The mammary glands under the influence of progesterone the epithelium grows milk ducts.
During pregnancy, progesterone
Progesterone - norm and pathology
is first formed in the corpus luteum of pregnancy (it is formed in place of the corpus luteum MC), and then the placenta. During this period, progesterone inhibits the contraction of smooth muscle of the uterus.
Regulation of the synthesis of the female sex hormones estrogen and progesterone is mediated by the cortex of the brain the hypothalamus responsible for the operation of the entire endocrine system and the endocrine glands pituitary, allocates special gonadotropic hormones (TG - follicle-stimulating and luteinizing) of the first and second half of the MP.
The amount of progesterone in the blood can be determined and its metabolite (exchange product) pregnanediol - urine. Inadequate maintenance of these hormones can talk about infertility or the threat of termination of pregnancy.
Symptoms of a lack of progesterone in women
Since progesterone provides the right for the second half of the MP, with its lack of MC violated. Most often there is a delay ovulation
Ovulation - How to determine as accurately as possible?
And then prolonged rejection endometrium, accompanied by prolonged painful bleeding. Progesterone is involved in the synthesis of corticosteroid hormones and adrenal cortex of male hormones androgen that affect a plurality of women in the body processes. Therefore, signs of a lack of progesterone in women - is:
- painful menstruation and intermenstrual bleeding;
- Depression, unexplainable mood swings
Mood swings in women - bad character or a disease?
Irritability
Irritability - you try to control my temper
, Aggressiveness, insomnia at night and sleepiness during the day before menstruation - premenstrual syndrome (PMS);
- vaginal dryness, pain during sexual intercourse;
- Androgen excess, which might cause excessive hairiness body overactive sebaceous glands of the skin, the appearance of acne and pigment spots on the skin; decreased skin elasticity, the appearance of premature wrinkles;
- fluctuations in blood pressure and associated headaches, dizziness, and sometimes - fainting;
- constipation, flatulence, bloating;
- disturbance of thermoregulation - increase or decrease in body temperature.
The lack of progesterone may be due to destruction of any part of the neuroendocrine system - the cerebral cortex (stress, lack of sleep), hypothalamus and pituitary gland (diseases, tumors), ovarian (tumors, cysts), adrenal, thyroid, liver (eg, cirrhosis). Hormonal disorders can begin in the background depletion (eg, women for a long time using various diets for weight loss), long uncontrolled hormonal contraceptives, and so on.
Symptoms of a lack of progesterone in pregnancy
The main function of progesterone in pregnancy is the inhibition of smooth muscle contraction of the uterus. If progesterone is produced insufficiently in the first 12 weeks of pregnancy, which may result in spontaneous abortion. Therefore, when the threat of termination of pregnancy, and increased muscle tone (hypertonia) of the uterus during this period shall be appointed by synthetic and natural analogs of progesterone (or djufaston utrozhestan).
Reduced production of progesterone during pregnancy also leads to defective secretory changes in the lining of the uterus and will hinder the normal development of the embryo.
Symptoms of a lack of progesterone can be eliminated completely if the time to see a doctor.
