Fetal and uterine weight increase
The weight of the fetus and uterus increases, which compresses the blood vessels and nerves in the pelvis and back, causing discomfort.
Posture change
Pregnancy will change the original center of gravity of pregnant women. In order to adapt to this change, pregnant women are likely to unconsciously adjust their posture, which will pull their muscles back and lead to back pain.
Hormone change
After pregnancy, a hormone called relaxin will be secreted to relax the ligaments and joints in the pelvic area and prepare for delivery. But relaxin can also relax the ligaments that support the spine, leading to spinal instability and back pain.
Cold compress and? heat
Cold compress, such as wrapping a bag of ice in a towel, can be placed on the painful part several times a day for about 20 minutes each time. After 2 ~ 3 days, it can be changed to hot compress, with hot towels, gauze and hot water bottles. Hot compress for half an hour every day can also relieve the pain. It should be noted that during pregnancy, it is necessary to avoid abdominal contact with high temperature.
♀? Adjust posture
Proper posture adjustment can avoid excessive pressure on the spine. For example, sleeping on the left side and putting a pillow between pregnant women's knees can reduce back pressure. Usually, when you sit down, you can use the backrest to support you, or you can put your feet on a pile of books or a small stool. Try to sit up straight with your shoulders back. Don't sleep on a soft bed. Too soft is easy to make the waist sink, causing or aggravating low back pain.
♀? by oneself
Regular exercise can enhance muscle endurance, improve body flexibility and help relieve muscle tension in the back. For pregnant women, the safer exercise methods are walking, swimming and riding a stationary bike. Pregnant women with low back pain can wear abdominal belts or special belts for pregnant women to support the waist and reduce the load.
