Why do I have back pain during the seven and a half months of pregnancy?

In the first three months of pregnancy, pregnancy reactions such as nausea, vomiting, dizziness, and sleepiness often occur. By the second trimester, these symptoms will disappear and the patient's body will gradually feel comfortable, so she eats more. This is also the reason for weight gain during pregnancy, which is very normal. When you are seven and a half months pregnant, you will have back pain because your belly begins to bulge. The causes of back pain also include these.

Causes of back pain in pregnant women

What causes back pain in pregnant women? Pregnant women may experience back pain during pregnancy. The main causes of back pain are as follows:

1. Hormonal changes in the body during pregnancy.

Hormonal changes in the body after pregnancy can cause many pregnancy reactions in pregnant women, and back pain is one of them. After pregnancy, hormone changes in the body cause the pelvic ligaments to relax to adapt to the growth of the fetus and the needs of future delivery. This will also cause the ligaments and fascia in the waist to relax, reducing their elasticity, making them prone to strain and causing low back pain.

2. The placenta and amniotic fluid increase, and the lumbar spine is overloaded.

This is the main reason for back pain in pregnant women. After pregnancy, the fetus and its attached placenta, amniotic fluid, etc. grow larger and larger day by day, increasing the burden on the front of the lumbar spine. In order to maintain balance, pregnant women must contract their back muscles forcefully when standing, causing the pelvis to tilt forward, forming a unique straight back posture. The back muscles continue to contract and they cannot relax and rest. Over time, fatigue will cause back pain.

3. Reduced amount of exercise.

After pregnancy, the amount of exercise for pregnant women is greatly reduced. Some pregnant women even lie down or sit for a long time. Lack of exercise can also cause a decrease in basic physical strength, thereby causing back pain in pregnant women.

4. Insufficient calcium supplementation.

During pregnancy, the fetus needs a lot of nutrients such as calcium to develop. If these nutrients are not consumed enough, it can easily cause osteoporosis and decalcification in pregnant women, which can also cause back pain.

The causes of low back pain in pregnant women vary in the early, middle and late stages of pregnancy. The back pain in pregnant women in the early stages of pregnancy will not be very severe. It is mostly back pain, which is mainly caused by the retroverted uterus and compression of the rectum and ligaments. Pregnant mothers do not need to worry.

Low back pain in the middle and late stages of pregnancy is mostly caused by the rapid development of the fetus, which causes the uterus to gradually enlarge and the abdomen to move forward. In order to maintain balance, the upper body tends to lean back, causing excessive lordosis of the spine and continuous tension in the back extensor muscles, resulting in excessive fatigue of the waist and back, which can easily lead to low back pain.

Treatment of back pain in pregnant women

Back pain in pregnant women is one of the common reactions during pregnancy. If there are no other complications, special treatment is generally not required. Regular exercise, maintaining correct walking posture, avoiding standing for long periods of time, and paying more attention to rest can effectively relieve the symptoms of back pain.

1. Mild low back pain

(1) Use a special pregnancy belt. Tie a belt or a special pregnancy belt around the pregnant woman's abdomen to support the pregnant woman's waist and relieve pain.

(2) Maintain a correct standing posture. The correct standing posture is to keep your legs slightly apart, your back straight, your chest up, and your chin tucked in. If you hold your posture correctly, your big belly won't be noticeable. Don't stand up or sit down too quickly, and it's best to have something to hold on to.

(3) Do appropriate exercise. You should also do appropriate exercise during pregnancy, choose suitable gymnastics or swimming for pregnant women, and exercise according to your personal situation to enhance your physical strength.

(4) Choose suitable beds, shoes, etc. Don't sleep on a bed that is too soft, as it can easily cause your waist to sink, causing or aggravating low back pain. Also choose more comfortable shoes and avoid wearing high heels.
