I. What is insomnia? Insomnia is a sleep disorder in which the person has problems falling or staying asleep, or wakes up feeling that their energy has not returned. Insomnia is not just about the amount of sleep you get. Each person needs a different amount of sleep. What are the symptoms? People with insomnia often have trouble falling asleep or waking up easily after falling asleep; feeling tired during the day; forgetting things or having trouble thinking clearly; being cranky, anxious, irritable or depressed; having low energy or lack of interest in certain things; having more mistakes or accidents than usual; worrying about not getting enough sleep. These symptoms can be severe enough to interfere with relationships or work. In addition, people who seem to get enough sleep may also have these symptoms. Third, should I get checked? It may not be necessary. Most patients do not need to be tested. Sometimes, patients do need certain tests, such as polysomnography or somatic movement recorder. Polysomnography: This is a test that is done in a sleep lab and usually lasts all night. During the test, a monitor is connected to your body to record body movements, brain activity, breathing and other bodily functions. 2. Body movement recorder: Activity and movement are recorded through a monitor or motion detector that is usually worn on the wrist. The test is done at home and takes place over several days and nights and will record the actual amount of sleep and sleep periods. IV. Are there any effects of insomnia during pregnancy? Pregnant women may have problems with poor sleep quality, lack of sleep at night, and severe daytime sleepiness throughout their pregnancy. These problems are caused, at least in part, by nighttime urination, lack of comfortable sleeping positions, etc. Poor sleep quality with obstructive sleep apnea (OSA) is of greatest concern. Advanced age, obesity, and frequent snoring (self-reported snoring days per week ≥3) predict frequent and episodic sleep apnea. Sleep apnea OSA during pregnancy can lead to an increased risk of preeclampsia and gestational diabetes mellitus. These pregnancy complications have no clear adverse effects on the fetus, except for sequelae. V. Is there a way to relieve it? 1.
