Why are expectant mothers prone to back pain?

First, the expectant mother indicates that she has been pregnant for a long time and has a big and heavy belly. There is a doctrine of stable selection in the theory of evolution, which roughly means that the fetus is more likely to survive under the condition of kilograms. In other words, the weight of your belly is more than six pounds, and in such a heavy situation, you have to support it day and night.

We know that even if you just hold a book of water, it will take less than an hour, and your hands will be very sore, not to mention the situation of high quality for a long time.

Second, in this case, your back is under a lot of pressure, and your muscles are always tense, maintaining a posture without changing will really be particularly sour. Some people work in front of the computer for a long time, and they are prone to cervical spondylosis, neck and shoulder pain, which is a reason.

Third, because of the large belly, many activities are restricted, including moving the back. Excessive accumulation of lactic acid, etc., and poor blood circulation, cause symptoms of low back pain.

Back pain is rare when you are first pregnant, and it usually occurs in the second and third trimesters.

I remember reading a book before, and the book said that because the fetus is getting bigger and bigger, we need to keep walking with our backs upright, and the time is up, and we will find that our backs hurt as soon as we relax.

Because our stomachs were so big, we had to hold our backs straight. Some people also experience rib pain, which is a pain in the bones under the chest.

This is because the stomach gradually gets bigger, little by little, and at this time it will rise too high against our ribs, and at this time, we will feel the bones under the chest hurt.

When Xiao Ke was pregnant with Dabao, her ribs hurt for a few months, and she couldn't stand the pain as soon as she ate, and at that time, she basically had four or five meals a day, but she was afraid of eating too much.

When I was lying down, I still didn't feel any pain, but when I sat up, I could clearly feel my stomach pressing against my ribs.

There will be many places that will be uncomfortable during pregnancy, and in the later stage you will find that the whole person is uncomfortable, because the belly is too big, at this time you will find that your back hurts even more, because the stomach goes down, and at this time you will feel that the root of the thigh hurts.

Since the position of the fetus is located in front of the lumbar spine, as the number of weeks of pregnancy increases, the upper body of the expectant mother will gradually become an anti-arch to maintain balance, that is, the typical backward posture presented by the expectant mother.

At this time, the curvature of the lumbar spine increases, coupled with the weakening of the support of the abdominal muscles, the lower back muscles of the expectant mother will be in a state of excessive tension, and at the same time, due to the concentrated supply of blood to the fetus, the hypoxia of the back muscles is more serious, and the lower back pain is inevitable at this time. During pregnancy, the ovaries secrete a substance called relaxin, which reduces the tightness of collagen in the joints, causing joint relaxation and loosening of ligaments, and weakening the strength to support the body. Especially in the second and third trimesters of pregnancy, the sacroiliac joint and interpubic fibrocartilage and its ligaments become relaxed, causing lower back or pelvic pain."

Excerpt from --- still have to give up after all.
