False contractions

Introduction From the 28th week of pregnancy, the phenomenon of "false contractions" often occurs in the abdomen. If the pregnant woman is standing or sitting in the same position for a long time, it will feel the hardening of the abdomen (ie, the symptoms of tight stomach), which is "false contraction." Pseudo-uterine contractions, also called prolonged contractions, are an occasional uterine contraction. Its characteristics are that the time of occurrence is irregular, and the degree is also strong and weak. False uterine contractions have started around 6 weeks of pregnancy, and it is not until the middle of pregnancy that they begin to feel.

Cause

Before the birth, due to the pulling stimulation caused by the lower fetal head, the "fake contractions" will become more and more frequent.

Differential diagnosis

No uterine contraction interval: no uterine contraction interval refers to the expected date of delivery, pregnant women have no contractions. An important feature of labor - regular uterine contractions or contractions. Contractions: uterine contractions (ie, contractions), begin to be irregular, weaker, gradually become regular, stronger and stronger, duration is extended, interval time is shortened, such as interval of 2-3 minutes, Lasts 50-60 seconds. By the time of the expected date of birth, only the contractions with pain are the precursors of childbirth. A few weeks before delivery, the uterus muscles are more sensitive, and irregular uterine contractions will occur, with short durations, weak strength, or limited to the lower part of the uterus. After a few hours, it stops again, and the cervix can not be opened. Therefore, it is not a labor, which is called a false contraction. The uterine contractions in labor are regular. The initial interval is about 10 minutes, the pregnant woman feels abdominal pain, and the duration of the pain is gradually extended to 40 seconds to 60 seconds. The degree is also increased, and the interval is shortened, about 3 to 5 minutes. When the uterus contracts with abdominal pain, you can feel the lower abdomen is very hard.
