Hormonal changes in pregnancy

Hormonal changes in pregnancy

Hormonal changes in pregnancy are natural and have an essential role contributing to the development and growth of the fetus in the 9 months. They are responsible for a lot of less pleasant symptoms of pregnancy: constipation, mood swings, low sexual desire, drowsiness and even lust.

Hormonal changes in pregnancy predispose you to extremely unpleasant conditions and symptoms sometimes, and your partner seems to have a hard time understanding that hormones are to blame. The communication between you and your partner must be a very good one, to be thoroughly informed and to expect some of the following effects of hormonal changes:

Disposition changes and crying from everything

Now you are happy, now you are sad, now you laugh, you immediately cry. It seems that crying from anything, like sudden mood swings, is an effect of excessive estrogen production in pregnancy, but also of the stress and stress you are experiencing in the first trimester, when the body goes through several transformations.


Sometimes, you may find that you have times when you are upset with almost anything and you are nervous about everyone around you, especially the partner.

You will scream more at them, you will reprove small things and you will find it unacceptable even the smallest thing that is not put in its place. The production of excess estrogen is also responsible for this effect. These starts are normal and it is advisable to warn your partner in advance that you will have such moments, so as not to get upset.

Fortunately, there is a secretion of substances in the body that come to counterbalance bad states. The production of endorphins from pregnancy is the one that helps you cope with irritability and is stimulated by sports and physical movement.

The shine of the task

Pregnancy glow is a consequence of hormonal changes in pregnancy. This is manifested by radiant, shiny and healthy skin. It mainly occurs in the second trimester, when hormonal storms are worsening and only the increased levels of estrogen are still in your body.

Stains on the skin during pregnancy

Some of the common skin conditions in pregnancy are caused by hormonal changes. While some pregnant women experience glowing skin, others may have acne or other blemishes and unpleasant marks on the skin, especially on the face or back. One of them is acne. It is caused by increased progesterone levels.

Digestive problems

From constipation to stomach burns, digestive problems are common in pregnancy and are a consequence of the "ravages" that progesterone does in the body, causing relaxation of the intestinal muscles and stomach.

Healthier and more beautiful hair

Many women claim that they have brighter and more resistant hair. This is an effect due to the high level of progesterone. During this period the level of dihydrotestosterone (DHT), the hormone responsible for hair loss, is low.

Morning woes

Most women experience morning sickness in the first trimester of pregnancy. These are caused by the increased level of hCG (human chorionic gonadotropin) in the body. It is the pregnancy hormone itself. In most cases, they decrease as you get through the second trimester of pregnancy, but some women may experience these unpleasant sensations throughout the sacina.

Sexual desire during pregnancy

Increased levels of progesterone and estrogen in pregnancy can make you feel very attractive, stimulate your libido and spice up your sex life. These hormones promote vaginal lubrication, sensitivity of the breasts and nipples and can increase blood flow in the pelvic area. These effects are felt in most women mainly in the second trimester of pregnancy.

But there are also cases where these hormones can have a reverse effect: they can decrease sexual desire and make women feel unattractive, especially due to body changes.

Estrogen and progesterone, the main hormones in pregnancy

The main hormones in pregnancy are:

  • estrogen;

  • progesterone.

Estrogen is a hormone released by the ovaries that is controlled by the luteinized hormone (LH). During pregnancy, it is secreted by the placenta. Its role is to stimulate and regulate progesterone production during the 9 months of pregnancy.

Progesterone is another pregnancy hormone that is normally found in very small amounts in the first part of a menstrual cycle. Like estrogen, this hormone is secreted by the ovaries and the yellow body. 10 days after ovulation, the progesterone secretion ceases and the ovulation begins. If the released egg is fertilized, then the hCG hormone produced by the placenta in formation will stimulate the yellow body to continue to produce progesterone and estrogen in pregnancy. The role of progesterone is to maintain the functions of the placenta, protect the fetus, prevent uterine contractions, intervene in the lactation process, etc.
