What are the causes of uterine contractions during mid-pregnancy?

The second trimester is an extremely special period in a woman's pregnancy cycle, and the frequency of uterine contractions in the second trimester is also very high. It can be seen that uterine contractions in the second trimester do not occur suddenly, and there must be a predisposing factor. So, what is the cause of uterine contractions in the second trimester? For details, please see the introduction for pregnant women below.

One is the fetal factor. When the fetus moves more, it will cause uterine contractions, but the intensity is not great.

The second is the factor of pregnant women, such as diarrhea, peritonitis, appendicitis and other diseases;

The third is the external environment. Pregnant women who are overworked, frightened, over-exercise, suffer strong impacts, or have bad living habits (smoking, drinking), or take certain medications can also cause uterine contractions.

The first aspect is beyond the control of expectant mothers. If the second factor occurs, seek medical attention in time. The third aspect should be avoided as much as possible, and attention should be paid to rest and not go to crowded public places.

Uterine contractions in the second trimester are regular uterine contractions, or uterine contractions. A few weeks before delivery, the uterine muscles are more sensitive and irregular uterine contractions will occur, which are short-lived, weak, or limited to the lower part of the uterus. It stops after several hours and cannot cause the cervix to open, so it is not labor and is called false labor.

The contractions of the uterus during labor are regular. Initially, the interval is about 10 minutes, and pregnant women feel abdominal pain, and then the duration of the pain gradually increases to 40 seconds to 60 seconds. The severity increases and the interval shortens to about 3 to 5 minutes. When the uterus contracts and abdominal pain occurs, the lower abdomen may feel hard.

As mentioned above, it is very normal to have uterine contractions in the second trimester. However, if the pregnant woman is overworked, suffers from a certain disease, is frightened, and the fetus has large movements, these are the main reasons for causing the uterine contractions to be more intense in the second trimester. Therefore, pregnant women in the second trimester must pay more attention.
