Colestyramine or cholestyramine (trade names Questran, Questran Light, Cholybar, Olestyr) is a bile acid sequestrant, which binds bile in the gastrointestinal tract to prevent its reabsorption. It is a strong ion exchange resin , which means it can exchange its chloride anions with anionic bile acids in the gastrointestinal tract and bind them ...
[7] [1] Cholestyramine, colestipol and colesevelam have all been used. Doses may not need to be as high as those previously used for hyperlipidemia. Many patients find them hard to tolerate, as although the diarrhea may improve, bloating and abdominal pain can worsen. [8] [9]
Insufficient sleep has been linked to weight gain, high blood pressure, diabetes, depression, heart disease, and strokes. [6] Sleep deprivation can also lead to high anxiety, irritability, erratic behavior, poor cognitive functioning and performance, and psychotic episodes. [7]
A sleep study is a test that records the activity of the body during sleep. There are five main types of sleep studies that use different methods to test for different sleep characteristics and disorders.

The information includes sleep onset time, sleep latency, number of awakenings in a night, time in bed, daytime napping, sleep quality assessment, use of hypnotic agents, use of alcohol and cigarettes, and unusual events which may influence a person's sleep. Such a log is usually made for one or two weeks before visiting a somnologist.
Chronic sleep deprivation (less than 8 hours of sleep) is associated with an increase in body mass index (BMI) and obesity. In a study with 3000 patients, it was found that men and women who sleep less than 5 hours have elevated body mass index (BMI). In another study that followed about 70.000 women for 16 years, there was a significant ...
Sleep diary layout example. Sleep medicine is a medical specialty or subspecialty devoted to the diagnosis and therapy of sleep disturbances and disorders. [1] From the middle of the 20th century, research has provided increasing knowledge of, and answered many questions about, sleep–wake functioning. [2]
REM sleep is characterized by high global cerebral blood flow, comparable to wakefulness. [79] In fact, many areas in the cortex have been recorded to have more blood flow during REM sleep than even wakefulness- this includes the hippocampus, temporal-occipital areas, some parts of the cortex, and basal forebrain.
