Risk of restless legs syndrome in pregnant women

Pregnancy is a time when a woman's body goes through a lot of changes, from the body's hormones to circulatory, respiratory and immune changes. In particular, restless legs syndrome in pregnant women greatly affects sleep and pregnancy health.

According to a study on September 27, 2001 that shows that in addition to the symptoms of morning sickness and shortness of breath, pregnant women also have a condition that causes discomfort and sometimes pain for pregnant women, affecting sleep, It's restless legs syndrome.
Restless legs syndrome (RLS) includes symptoms related to movement disorders, making women want to move and move the legs. Besides the above symptoms, pregnant women also feel uncomfortable or uncomfortable. People with restless legs syndrome have described their legs as crawling, tingling or aching and tingling, and sometimes painful sensations. A few cases of sudden muscle twitching were noted.
Symptoms are often worse in the evening or at night, severely affecting the mother's sleep and restricting leg movements, making it difficult to walk.

Restless legs syndrome in pregnant women is common in older women. The incidence of the disease increases with age. About 5 - 10% of the population experiences this condition during pregnancy.
According to a study by Mauro Manconi, MD, Vita-Salute University in Milan, Italy on “Pregnancy and Restless Legs Syndrome”. The team used a recently revised international definition of the condition, in which the cause of RLS remains unknown. The results of the study suggest that there are many factors to this syndrome:
The first pregnancy associated with restless legs syndrome was reported in 1940, with several other studies confirming the association. this contact. Nearly 600 Italian women participated in the study, they were evaluated for restless legs syndrome in pregnant women present from the beginning of pregnancy. After giving birth, within two days, these women will talk to a pair of neurologists who are certified in Sleep Medicine. For the next 6 months, the researchers followed people whose doctors diagnosed them with restless legs syndrome during pregnancy. More than 26% of the women had RLS as a result. In it, most of them are experiencing this situation for the first time. Almost 25% of symptoms occur once per week and almost 15% more than 3 times per week. This makes the mother sleep less, lose more sleep and be more prone to excessive daytime sleepiness. If RLS is encountered in the third trimester of pregnancy, it is a poor prognostic factor, especially in the seventh and eighth months of pregnancy. Restless legs syndrome in pregnant women will disappear after one month of delivery, only 7% of women still have restless legs syndrome.

One possible cause of restless legs syndrome is lower iron stores in the blood as well as in the liver compared to women without this syndrome. During pregnancy, a woman needs a large amount of iron to supply the fetus. In addition, pregnant women also lose iron during childbirth due to blood loss. However, after 3 months of delivery, iron levels improved and restless legs syndrome also disappeared.
Another theory blames hormones for RLS in pregnant women. The researchers, writing in the Journal of Neurology, say: "The rapid and significant improvement of restless legs syndrome after childbirth is based on hormonal causes rather than the iron hypothesis." During pregnancy, the hormones change greatly, especially the two hormones estrogen and progesterone, besides during pregnancy there is an increase of a few other hormones such as β-hCG.
There are also a few other causes such as: Genetics, increased sensitivity during pregnancy,...
