Hormonal Changes During Pregnancy: What to Expect
Pregnancy is a beautiful and transformative experience for women, but it also comes with a lot of changes, especially in the hormonal department. Hormonal changes during pregnancy are a normal and essential part of the journey to motherhood. These changes are necessary for the growth and development of the baby, as well as preparing the mother’s body for childbirth and breastfeeding.
In this blog post, we will discuss the different hormonal changes that occur during pregnancy and what to expect. We will also touch on the common symptoms that may accompany these changes and how to manage them. So, if you’re expecting or planning to get pregnant, keep reading to learn more.
1. Human Chorionic Gonadotropin (hCG)
One of the first hormones to increase during pregnancy is human chorionic gonadotropin (hCG). This hormone is produced by the placenta and is responsible for maintaining the production of the hormone progesterone. It is also the hormone detected by pregnancy tests.
During the first trimester, hCG levels rise rapidly, doubling every 48-72 hours. This increase in hCG can cause symptoms such as nausea, vomiting, and breast tenderness. These symptoms usually subside by the end of the first trimester as hCG levels stabilize.
2. Estrogen
Estrogen is another hormone that increases significantly during pregnancy. It plays a crucial role in the growth and development of the baby, as well as preparing the mother’s body for childbirth. Estrogen helps to increase blood flow to the uterus and stimulates the growth of the milk ducts in the breasts.
The surge in estrogen levels can cause various symptoms, including fatigue, headaches, and mood swings. It can also contribute to the development of pregnancy-related conditions, such as gestational diabetes and preeclampsia. However, these conditions can be managed with proper medical care.
3. Progesterone
Progesterone is a hormone that is vital for maintaining a healthy pregnancy. It helps to relax the muscles in the uterus, preventing contractions that could lead to premature labor. Progesterone also stimulates the growth of breast tissue in preparation for breastfeeding.
Increased levels of progesterone can cause symptoms such as fatigue, constipation, and bloating. It can also contribute to the relaxation of the muscles in the digestive tract, leading to heartburn and indigestion. These symptoms can be managed with dietary changes and medications prescribed by a doctor.
4. Relaxin

As the name suggests, relaxin is a hormone that helps to relax the muscles and ligaments in the body. During pregnancy, relaxin is produced by the placenta and helps to prepare the mother’s body for childbirth by loosening the ligaments in the pelvis.
The increase in relaxin levels can cause joint pain and discomfort, especially in the hips and pelvis. This is due to the loosening of the ligaments, which can lead to instability and discomfort. Gentle exercises and stretches, as well as a pregnancy support belt, can help to alleviate these symptoms.
5. Oxytocin
Oxytocin is known as the ‘love hormone’ and is responsible for inducing labor and promoting bonding between mother and baby. During pregnancy, oxytocin levels increase, preparing the body for childbirth. It also helps the uterus to contract during labor and stimulates the release of breast milk.
The rise in oxytocin levels can cause emotional changes, including mood swings and anxiety. It can also contribute to postpartum depression in some women. Seeking support from loved ones and talking to a healthcare provider can help to manage these emotional changes.
6. Prolactin
Prolactin is the hormone responsible for milk production in the breasts. During pregnancy, prolactin levels increase in preparation for breastfeeding. It also helps to suppress ovulation, preventing the mother from getting pregnant again while breastfeeding.
Elevated levels of prolactin can cause symptoms such as breast tenderness and swelling. It can also lead to a decrease in libido and vaginal dryness. These symptoms usually subside after giving birth or once breastfeeding is established.
7. Thyroid Hormones
The thyroid gland produces hormones that regulate metabolism and energy levels in the body. During pregnancy, the thyroid gland becomes more active, producing more hormones to support the growth and development of the baby.
Fluctuations in thyroid hormone levels can cause various symptoms, including fatigue, weight changes, and mood swings. It is essential to monitor thyroid levels during pregnancy and seek medical treatment if levels are too high or too low.
In conclusion, hormonal changes during pregnancy are necessary for the growth and development of the baby and preparing the mother’s body for childbirth and breastfeeding. While these changes can cause discomfort and symptoms, they are a normal part of the journey to motherhood. If you experience any severe or concerning symptoms, always consult with your healthcare provider for proper guidance and support.
