Why Do Pregnant Women Have Mood Swings?

One of the most recognizable symptoms of pregnancy is mood swings. With all of the changes that are occurring in the pregnant woman's body, it is no surprise that mood swings accompany these changes. According to the American Pregnancy Association, physical stresses, fatigue and hormone changes can all contribute to mood swings.

Timing

Mood swings are most common during the first trimester and towards the end of the third trimester. In the first trimester, the body is undergoing rapid changes as the body prepares to provide a home for the growing fetus. These changes can trigger all three of the main causes for mood swings. Late in the third trimester, the same applies, but in addition, the emotional stress of preparing for labor and delivery along with the subsequent lifestyle changes can also play a role.

Physical Stresses

Rather than only supporting the woman, organs and bodily functions now have to work to support the lives of two. In the beginning, the pregnant body begins to change rapidly including increases in breast size, introduction of morning sickness and an increase in emotional stressors, particularly if the pregnancy is unplanned. Dealing with this rapid onset of changes can cause a pregnant woman to swing from happy one minute to crying the next.

Fatigue

Fatigue is most prevalent in the first and third trimesters. Many women are surprised at how tiring pregnancy can be. In the first trimester, this is due to the body directing energy towards the production of the placenta and other systems to support the fetus. An increase in urinary frequency can also interrupt sleep several times during the night making getting a good night's sleep nearly impossible. In the third trimester, the extra weight along with dealing with the pains and pressure of the growing uterus can all contribute to fatigue. Finding a comfortable position for sleep can also be difficult in the last trimester. Many believe that lack of sleep is the body's way of preparing itself for the lack of sleep that will accompany having a newborn in the home.

Hormone Changes

Throughout the pregnancy, hormones fluctuate to support the body's different functions to support the fetus. While these hormone changes are necessary, they can wreak havoc on a woman's mood causing her to go from chipper to angry in a flash. Since she has no control over hormone changes, she also has little control, if any, over her erratic mood swings. Feeling a loss of control over emotions can cause even more mood swings for some.

Considerations

To combat mood swings, get plenty of rest, eat well and plan relaxing activities such as a prenatal massage. If mood swings become severe and interfere with normal functioning, call the doctor. According to the American Pregnancy Association, pregnancy increases the chances for depression. While self-medicating is not recommended, the doctor can prescribe medications to alleviate the symptoms or refer her to a counselor for further assistance.
