Risk of heart diseases, depression and health with social jet lag
Earlier studies established an association between type 2 diabetes (T2D) and sleep as insufficient sleep causes harmful effects on blood sugar levels. Now, a study by researchers at the American Academy of Sleep Medicine (AASM), Darien, Illinois, United States shows increased risk of heart diseases and heart health with social jet lag (delay in sleep schedule during weekends or on Saturday and Sunday). The study shows 11 percent incremental risk of heart diseases with each hour of social jet lag. The study also shows risk factor associated with social jet lag is independent of insomnia symptoms and how many hours an individual sleeps. Authors of the study say social jet lag is an important circadian marker and regular sleep schedule is a simple, inexpensive and effective way to prevent heart diseases. Researchers 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. Sleep Foundation, United States says alcohol gives a poor quality of sleep even though an individual may asleep quickly. For better sleep, they advise to keep same sleep schedule even during weekends (and all days), do daily physical exercise, to have bedtime ritual and to avoid daytime naps. Lead author of the study was Sierra B Forbush, the University of Arizona. The study findings were published in the American Academy of Sleep Medicine (AASM), under the title Sociodemographics, Poor Overall Health, Cardiovascular Disease, Depression, Fatigue, and Daytime Sleepiness Associated with Social Jetlag Independent of Sleep Duration and Insomnia.
Bariatric surgery reduces heart failure risk in severely obese individuals
Individuals with body mass index (BMI) more than 30 kg/m2 are considered as overweight or obese. New guidelines issued by the American Diabetes Association recommends Bariatric surgery to poorly controlled patients with type 2 diabetes with BMI of 30 kg/m2 or higher. A study by researchers at Geisinger Obesity Institute shows reduction to long-term heart failure risk in obese individuals (without a history of heart failure or stroke) by more than 50 percent with weight loss surgery or Bariatric surgery. This was the first study showing risk reduction to congestive heart failure with Bariatric surgery. Researchers studied more than 3,448 individuals where fifty percent of them had undergone gastric bypass surgery. The study results show
There is no direct association between obesity and incidents of heart failure. Risk of heart attacks increases if an individual is more than 35 kg/m2 BMI. The overweight or obesity increases risk factors for heart diseases such as cholesterol, blood pressure, blood sugar or glucose and damages arteries by stiffening or clogging of arteries. The gastric bypass surgery changes body metabolism in addition to weight loss and reduction in belly fat. Some individuals may experience remission of diabetes. So healthcare experts prefer calling gastric bypass surgery as "Metabolic Surgery".
Lead author of the study was Peter N Benotti, M.D., a clinical investigator, Geisinger Obesity Institute, Danville, Pennsylvania. The study findings were published in the journal of the American Heart Association, under the title Bariatric surgery shrinks heart failure risk in severely obese.
