Causes of insomnia in pregnancy

It takes time to fall asleep, wake up often during the night and difficulties in falling asleep again, waking up early ... This is what many pregnant women suffer (more than 85%), especially in the third trimester (although not exclusively), have its causes

The most common causes of insomnia during pregnancy These include increased urinary frequency, backaches, gastroesophageal reflux, restless legs syndrome, nausea and vomiting (during the first trimester of pregnancy) and fetal movements (during the third).

  • The problem of nausea and vomiting It is much more frequent in the first trimester than in other stages of pregnancy and affects some women even at night, making sleep difficult. To control nausea remember not to lie down just after meals, eat small amounts and low-fat foods, take gingerbread cookies (natural remedy against nausea) and those foods that do not cause you repulsion ...

  • Gastroesophageal reflux affects more than 53% of pregnant women at night, making sleep difficult. Pregnancy hormones and little stomach space cause longer and heavier digestions. Reflux is characterized by a feeling of burning in the chest or throat called 'acidity', and sometimes you can feel the taste of the stomach fluid in the back of the mouth, because this liquid "rises." Some ways to reduce this discomfort is to avoid large, spicy, greasy or acidic foods; not eat right before bedtime; wear baggy clothes; sleep with the trunk elevated slightly ...

  • During pregnancy you urinate more frequently throughout the day and, of course, this also happens at night. The reasons are mainly the increase in the volume of fluids in the body of the pregnant woman and the increase in the volume of the uterus, which increasingly presses the bladder. About 70% of pregnant women indicate that this is a reason for insomnia. Even so, do not deprive yourself of drinking water during pregnancy because you need to be well hydrated (and urinate purifies toxins from the body), but try not to drink so much at night, before bedtime and go to the bathroom just when you sleep .

  • Backaches and other muscle discomfort related to the increase in uterine volume (the body has to find a new balance due to the increase in the abdomen and the curvature of the spine) also influence sleeping difficulties. During pregnancy, especially in the third trimester, pains increase, posture is not found, punctures, cramps in feet and legs are suffered ... About 50% of pregnant women argue these causes of insomnia.

  • Fetal movements They also make sleep difficult in 41% of cases. What you thought was an incredible and exciting start at about 18 or 20 weeks of pregnancy may not be as fun if the baby's movements in the belly start to hurt your ribs and this prevents you from sleeping a few nights in a row. Luckily, the baby also seems to relax during the night hours (as long as the mother also succeeds, which as we see is not easy).

  • Restless legs syndrome, an unpleasant sensation that the legs cannot stand when they are at rest. The pregnant woman feels a tingling sensation, burning… and the only way to remedy it is to move her legs, sometimes it is done uncontrollably because it relieves. In extreme cases it can also affect the arms. It is estimated that restless legs syndrome affects 30% of pregnant women and hormonal changes may be behind it (together with possible low iron levels, changes in the structure of the pelvis ...). What can be done to avoid this discomfort is to get enough physical activity during the day, so that there is a better rest.

  • Another reason reported by pregnant women for bad rest in the third trimester is snoring. Eye if there is a problem of sleep apnea or underlying hypertension or diabetes, you should consult your doctor. What happens is that changes in the mucosa of the respiratory tract due to excessive secretion and increased blood flow predispose both to hoarseness and obstruction of the upper airways.

In addition, a higher prevalence of insomnia symptoms has been found among multiparous women and women who do not exercise. The increase in heart rate may also have to do with keeping the woman in a constant state of alertness and with less sleep. Finally, there are studies that indicate that the increase in estrogen and progesterone decreases deep sleep.

Definitely, that it costs you to sleep well in pregnancy is normal and if lack of sleep affects your quality of life and during the day your body and your mind suffers, you may suffer insomnia. In any case, we will soon tell you what you can take against insomnia while pregnant and what remedies exist, without risks, to sleep as well as possible. An important advance: Do not self-medicate or take anything they tell you that is useful for resting.
