Why do I have back pain during the 4th month of pregnancy?

Ten months of pregnancy is a happy yet painful thing for every mother. The birth of a new life always brings a lot of joy, but it is also accompanied by various physical discomforts, such as vomiting and nausea in the early stages of pregnancy. As the baby in the belly begins to grow bigger day by day, the burden on the woman's waist will become heavier. Women may feel back pain or even thigh pain in the late pregnancy. Let me introduce to you the specific reasons for back pain after pregnancy.

Most of the time, back pain is a reaction to pregnancy, and sometimes it is caused by changes in body posture.

1. Normal pregnancy reaction

If you only experience lower back pain in the early stages of pregnancy but no vaginal bleeding, this is caused by the fertilized egg implanting into the endometrium. As the fertilized egg gradually grows after implantation, the uterus is stimulated and sometimes uterine contractions occur. The hormone levels also change at this time, so this is lower back pain caused by the stimulation of the uterus during pregnancy. There may also be slight abdominal distension and pain, which is a normal reaction to pregnancy and there is no need to worry.

2. Changes in pregnant women’s body posture

In the early stages of pregnancy, due to the influence of hormones, the joint ligaments relax, the uterus enlarges, and compresses the pelvic tissues and nerves. As the abdomen enlarges, the body's center of gravity gradually moves forward, forcing the pregnant woman's shoulders to move backward accordingly to maintain body balance. The neck is slightly flexed to compensate and maintain the head upright. As a result, the normal curvature of the spine increases, leading to lordosis, which causes local muscle pulling and the appearance of low back pain in early pregnancy. Therefore, the closer to full term, the more likely pregnant women are to experience neck, back and waist pain.

Pregnancy always brings various discomforts. You should usually maintain a positive and optimistic attitude, and pay attention to diet conditioning. In order to relieve the symptoms of lower back pain, you can put a pillow under your waist when sleeping to reduce the weight on your waist. Try not to maintain the same posture for a long time. You can also do some exercises for pregnant women under the guidance of a professional coach.
