What is the cause of lower back pain during pregnancy?

Generally speaking, after pregnancy, a woman's menstruation will stop and there will be no problem of spotting. But sometimes, pregnant women will find blood in their leucorrhea and feel extreme pain in their waist. Is this a normal condition? Pregnant women who are 40 weeks pregnant generally need to pay special attention to changes in their bodies, so they must understand this phenomenon in a timely manner.

What should I do if I have severe back pain after spotting at 40 weeks of pregnancy?

During pregnancy, a thick, bloody mucus plug may block the cervix and may pass out of the vagina before labor begins or in the early stages of labor. The so-called "red show" is caused by the contraction of the uterus, the gradual expansion of the cervical canal, and the mixing of mucus in the cervix and a small amount of bleeding from the cervical canal wall. This is a sign that the uterus is beginning to expand and dilate, a reliable sign that labor is about to begin.

What should you pay attention to when you see blood at 40 weeks of pregnancy?

1. Pregnant women have abdominal discomfort

In the later stages of pregnancy, the rapid growth of the uterus will cause the intestines in the lower abdomen to move upward or to the sides: sometimes the intestines will be squeezed near the liver; as the uterus grows, it will also rotate. These changes may cause a certain degree of pulling on the round ligament and broad ligament next to the uterus, causing pulling pain in the groin on both sides.

2. Difficulty breathing and chest tightness

This symptom is very common in pregnant women, especially in the last three months. The up and down movement of the diaphragm will be affected by the enlarged uterus, and pregnant women need to increase the depth of each breath to allow the baby to have sufficient oxygen. At this time, pregnant women should reduce their activity and maintain a happy mood.

3. Frequent urination and urinary incontinence

This is because the bladder is compressed in late pregnancy, causing its capacity to decrease. At the same time, the change in the relative position of the organs in the pelvic cavity increases the pressure on the bladder. Therefore, many pregnant women are prone to urine leakage from the urethra when they exert force during pregnancy, which is the so-called urinary incontinence. At this time, pregnant women should drink more water, go to the toilet more often, and not hold urine to prevent infection.

Symptoms of back pain in pregnant women

1. Early pregnancy

The low back pain at this stage will not be particularly severe, the pain is relatively mild, mostly waist and back pain. Low back pain during this period is often caused by the retroverted uterus, which compresses the rectum and ligaments, so pregnant women do not need to worry. However, if the following symptoms occur, you need to pay attention.

(1) If low back pain is accompanied by vaginal bleeding and the pain is severe, you should pay attention to the possibility of miscarriage or ectopic pregnancy and go to the hospital for examination immediately.

(2) If the lower back pain is severe enough to affect movement or radiate to other parts of the body, you should go to the hospital for examination, find out the cause, and receive timely treatment.

(3) If lower back pain is accompanied by leg cramps, it may be due to calcium deficiency.

(4) Low back and leg pain accompanied by sciatica may be caused by a lack of vitamin B1.

2. Second and third trimester

The back pain that pregnant women experience during this period is because the uterus gradually enlarges due to fetal development. In order to maintain body balance, the upper body begins 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 back pain. This pain is not sudden and the symptoms can be relieved after bed rest.

Severe symptoms may affect the fetus, so you should see a doctor in time to avoid serious consequences.
