All about the contractile uterus

Are you experiencing recurrent contractions during your pregnancy ? Have you ever heard of a contractile uterus? How can you recognize it, and should you be concerned?

What is a contractile uterus?

The uterus is the organ of the female genital tract in which fertilization takes place and the fertilized egg develops into a fetus.

The contractile uterus appears in women around the 16th week or fourth month of pregnancy. This applies to all women, regardless of the different uterine shapes. The uterus is made up of a muscle called the myometrium , which contracts spontaneously during pregnancy. These contractions occur repeatedly. They can cause irregular pain lasting between 30 seconds and 1 minute. If you experience more than a dozen in a single day, it's best to visit your gynecologist to make sure there isn't a problem with the cervix, such as it opening prematurely. This can be very dangerous and can lead to premature delivery.

It's a dysfunction involving contractions. The contractions associated with a contractile uterus are different from those associated with childbirth: they are not as painful. Associated symptoms also include a hard lower abdomen for a few seconds.

Some women may confuse the contractile uterus with the movements of the child, which can only be felt locally.

In any case, if you are prone to strong contractions, persistent pain, or if you have any doubts about your pregnancy, consult a women's health specialist.

What causes a contractile uterus?

A contractile uterus can be caused by a number of factors. l

• This may be due to an increase in the volume of the uterus, i.e. as the baby grows, it tends to stretch. This can cause pain in several parts of the body: in the ligaments, as well as a feeling of heaviness in the lower abdomen and pubic area;
• Contractions to prepare for labor l At the end of your pregnancy, you may experience false contractions. They are not painful and are intended to prepare you for labor.

In any case, there's no need to worry as long as they remain irregular, not too intense and not repeated too often during the day. But if they s'intensify and become more regular (even if you're nowhere near term), you may have a contractile uterus.

What are the signs of a contractile uterus?

There are several signs that can help you determine whether you have a contractile uterus. Especially if you are at the end of your pregnancy.

Chronic symptoms

It can s'be chronic symptoms such as:

• Intense fatigue;
• A stomach that hardens for no good reason, at any time of day;
• A protruding belly that often changes shape;
• Sensations of tightness in the hips and lower abdomen l.

False contractions

You may also experience false contractions. The uterus is made up of a muscle called the myometrium. Inside this muscle is the endometrium. This is where the fetus develops. During pregnancy, as the fetus develops, the muscle stretches and increases in volume. This is why you may experience pain due to stretching of the uterine muscle.

These are known as Braxton Hicks contractions. They are similar to menstrual cramps. They will prepare your body for childbirth.

Pregnancy pain

Some women experience pain during pregnancy, particularly ligament pain. The uterus is held to the pelvic bones by ligaments. As the baby grows, this organ enlarges, and the ligaments stretch to a greater or lesser extent in order to support the baby's weight. It is this stretching of the ligaments that causes unpleasant, painful pulling sensations. These pains usually appear at the beginning and end of pregnancy.

How do you get diagnosed with a contractile uterus?

It's sometimes difficult to know s s whether it's a contractile uterus or the sensations associated with the baby's movements, which are most common ina first pregnancy.

One way to determine this is to compare their extent. When a contraction occurs, it's the whole belly that hardens. When it's a much more local tension, it's caused by the baby's activity.

To diagnose a contractile uterus, the healthcare professional (gynecologist or midwife) will examine the cervix by means of a vaginal touch. This will reveal whether the contractions are having an impact on the degree of opening. The gynecologist will then monitor all contractions for 1 hour to determine their number and intensity.

Another test: lurinalysis will also ensure sthat there is no infection causing these symptoms.

After the tests, and depending on the results, the specialist will suggest a treatment or care plan tailored to your situation. 

Are there any treatments to reduce contractions?

Several solutions can help:

Drug treatments

There are several medications that can stop or relieve contractions:

• Antispasmodics such as Spasfon;
• Tocolytics such as Salbutamol.

If you're less than 34 weeks pregnant, corticosteroids can be taken to accelerate fetal lung maturation and reduce the risk of premature delivery.

Precautions to be taken

If you have a contractile uterus, it's important to rest, limit physical activity and car journeys, and take care of your health, etc. In certain cases, and under the advice of a doctor, you can also be confined to bed. Rest is very important in these cases.
