Why is my arm numb when I'm pregnant?

Pregnant women are pregnant women, an identity in human society, who share common psychological, physiological characteristics, and consumption needs. Pregnancy is a special physiological period that requires enhanced nutrition, because all the nutrients needed for fetal growth and development come from the mother, and the pregnant woman herself needs to reserve nutrients for delivery and milk secretion. Therefore, ensuring that the nutritional status of pregnant women remains normal during pregnancy plays a very important role in the pregnancy process and the development of the fetus and baby. Every move of a pregnant woman affects the whole family.

Numbness in the arms of pregnant women is often caused by malnutrition, or by long-term local pressure. It is recommended that the current situation requires an increase in nutrient intake and appropriate exercise. Do not keep the same position when sleeping.

In addition, pregnant women in the late pregnancy will suffer from edema, and blood and lymph will seep out, which will affect the carpal tunnel in the hand. The carpal tunnel is connected to the palm, and the increased pressure in the carpal tunnel will compress the nerves in the hand and cause numbness in the hand. This can also cause numbness in the pregnant woman's arms.

As the uterus and fetus grow, the sleeping position of pregnant women becomes more and more important, especially in the late pregnancy, that is, 7 to 9 months of pregnancy. Poor sleeping position of pregnant women will not only affect the position of the uterus, but also increase the pressure of the pregnant uterus on surrounding tissues and organs, affecting the blood flow to the uterus and placenta.

The left side sleeping position for pregnant women can reduce the pressure of the enlarged pregnant uterus on the pregnant woman's aorta and iliac artery, maintain normal blood flow in the uterine artery, ensure blood supply to the placenta, and provide the fetus with the nutrients needed for growth and development. Lying on the left side can reduce the pressure of the pregnant uterus on the inferior vena cava and increase blood flow returning to the heart. The increase in the amount of blood returning to the heart can increase the blood flow to the kidneys, improve the blood supply to the brain tissue, and help avoid and alleviate the occurrence of pregnancy-induced hypertension syndrome.

The right side sleeping position for pregnant women will cause the uterus to rotate to the right to varying degrees. This will put the ligaments and mesentery that maintain the normal position of the uterus under tension. The blood vessels in the mesentery are stretched, affecting the blood supply to the fetus, causing chronic fetal hypoxia. In severe cases, it can also cause fetal suffocation and death.

The best sleeping position for pregnant women is lying on the left side. This position can turn the right-rotated uterus to an upright position, thereby reducing the resulting fetal position and delivery abnormalities. It can also prevent the uterus from compressing the veins of the inferior cavity, increase the amount of cardiac blood output in pregnant women, reduce edema, improve the blood perfusion of the uterus and placenta, help reduce premature birth, and prevent the uterus from compressing the kidneys, thus benefiting the growth and development of the fetus and eugenics.
