The Risk Of Heart Diseases, Depression And Poor Health With Social Jet Lag (Jetlag)
The earlier studies have established an association between type 2 diabetes (T2D) and sleep as insufficient sleep can cause a harmful effect on the blood sugar (glucose) level of an individual.
Now, a study at the American Academy of Sleep Medicine (AASM), Darien, Illinois, the United States shows an increased risk of heart diseases and heart health with the social jet lag (a delay in sleep schedule).
The study shows an 11 percent incremental risk of heart diseases with each hour of social jet lag (or jetlag). The study also shows the risk factor associated with social jet lag is independent of insomnia symptoms and how many hours the person sleep.
The authors of the study say that the social jet lag is an important circadian marker and the regular sleep schedule is a simple, inexpensive and effective way to prevent heart diseases.
The researchers have studied 984 adult individuals aged between 22 and 60 years and came to this conclusion.
The American Academy of Sleep Medicine says an individual should regularly sleep for seven or more hours per night for good health. The Sleep Foundation, the United States says that drinking alcohol can give a poor quality of sleep even though an individual may fall asleep quickly. For better sleep, they advise to follow the same sleep schedule every day even during weekends (and all days), do daily physical exercise, to have a bedtime ritual and to avoid daytime naps.
The lead author of the study was Sierra B Forbush, the University of Arizona. The study was published on April 28, 2017, in the American Academy of Sleep Medicine (AASM). Title of the article is "Sociodemographics, Poor Overall Health, Cardiovascular Disease, Depression, Fatigue, and Daytime Sleepiness Associated with Social Jetlag Independent of Sleep Duration and Insomnia."
Bariatric Surgery Can Reduce The Risk Of Heart Failure In Severely Obese Individuals
An individual with body mass index (BMI) more than 30 kg/m2 is considered as obese. The new guidelines issued by the American Diabetes Association has recommended the Bariatric surgery for poorly controlled patients with type 2 diabetes with a BMI of 30 kg/m2 or higher.
A study at the Geisinger Obesity Institute shows a reduction to long-term risk of heart failure in obese individuals (without a history of heart failure or stroke) by more than 50 percent with Bariatric surgery (a weight loss surgery). This is the first study showing the risk reduction to congestive heart failure with Bariatric surgery.
The researchers have studied more than 3,448 individuals. About 50 percent of them have undergone gastric bypass surgery. The study shows the following results.
There is no direct association between obesity and the risk of heart failure.
But, obesity can increase the risk factors for heart diseases such as cholesterol, blood pressure, blood sugar (glucose) and the damage (stiffening or clogging of arteries) to the arteries. The risk of heart diseases can increase if the body mass index (BMI) of an individual is more than 35 kg/m2.
The gastric bypass surgery can change the body metabolism in addition to weight loss and reduction in the belly fat. Some individuals may experience the remission of diabetes. Healthcare experts often prefer to call the gastric bypass surgery as "Metabolic Surgery".
The lead author of the study was Peter N Benotti, M.D., a clinical investigator, Geisinger Obesity Institute, Danville, Pennsylvania. The study was published on May 23, 2017, in the journal of the American Heart Association. Title of the article is "Gastric Bypass Surgery Produces a Durable Reduction in Cardiovascular Disease Risk Factors and Reduces the Long-Term Risks of Congestive Heart Failure."
