What causes stomach pain during the fourth week of pregnancy?

Women shoulder the important task of bearing offspring. They bear the dual pressures of work and family, so the whole pregnancy process is difficult and arduous. What is the reason for stomach pain four weeks into pregnancy? According to experts, it is mainly due to the abdominal discomfort caused by the gradual increase in pressure on the uterus. Pregnant women must relax and not overwork. If conditions permit, they can work temporarily and stay at home to take care of the fetus while waiting for the baby to arrive.

The pathogenesis of abdominal pain during pregnancy mainly lies in the blockage or malnutrition of the uterine vessels, which leads to poor circulation of Qi and blood. "Pain occurs when there is no circulation" and "pain occurs when there is no nourishment". Just as You Zaijing said in "Jinkui Yaolue Xindian": "The blockage of the cell membrane means that the cell membrane vessels are blocked, the blood is insufficient and the qi cannot flow." However, blockage or malnutrition can be divided into deficiency and excess. Deficiency is caused by blood deficiency, weak qi, and decline of yang, while excess is caused by qi stagnation and blood stasis. The lesions are in the cellular vessels and collaterals, and the fetal origin is not damaged. However, if the abdominal pain persists and recurs repeatedly, it may further damage the fetus, causing fetal movement disorder or even miscarriage.

Pathogenesis:

1. Blood deficiency due to deficiency of blood or spleen deficiency. After pregnancy, blood gathers in the uterus to nourish the fetus, the yin blood becomes deficient, and the uterine vessels are deprived of nourishment, resulting in lower abdominal pain. If blood is deficient and qi is weak, blood will not flow smoothly, and qi deficiency will be unable to lead blood, causing sluggish and painful blood vessels.

2. Qi stagnation causes depression, blood goes down to nourish the fetus after pregnancy, liver blood is deficient, the liver loses its nourishment and the qi discharge is impaired, or the emotions are injured after pregnancy, the liver loses its smooth flow, the qi is not smooth, or the fetus gradually grows, which hinders the rise and fall of qi and causes stagnation. Stagnation of Qi will lead to obstruction of blood circulation and blockage of blood vessels, which will cause pain in the lower abdomen.

3. The patient has a weak constitution and is yang deficient, and is further affected by the cold evil after pregnancy, which causes the uterine vessels to lose warmth, hindering the smooth flow of qi and blood, thus leading to abdominal pain.

4. Blood stasis and abdominal masses. After pregnancy, due to qi stagnation or cold stagnation, blood stasis blocks the Chong and Ren meridians, uterus, uterine vessels and uterine networks. Pain occurs when the blood stasis is blocked, leading to abdominal pain.

6 Diagnostic points Diagnostic basis

1. Lower abdominal pain that occurs during pregnancy is generally not severe but often recurs, which is the main basis for diagnosis. There are no obvious signs during examination.

2. Medical history: history of amenorrhea and early pregnancy reactions.

3. Clinical manifestations: Lower abdominal pain, or persistent pain in the lower abdomen, or cold pain and discomfort, or pain in the lower abdomen and ribs during pregnancy.

The reasons for abdominal pain in the fourth week of pregnancy have been explained above, but pregnant women should also pay attention to their own conditions. If severe pain persists, do not take it lightly. Go to the hospital to see an obstetrician and gynecologist for diagnosis in time. If necessary, you must be hospitalized for observation to prevent accidents to the fetus in the womb. It is important to remind you that during pregnancy, expectant mothers can do some light outdoor activities to divert their attention and relax, and everything will get better.
