The incidence of obesity is increasing worldwide. In addition to diabetes mellitus, hypertension, hypercholesterolemia,obstructive sleep apnea is one of the obesity associated co-morbid conditions.This is one of the most dreaded condition and can cause sudden death during sleep. People with obstructive sleep apnea (OSA) are more likely use with continuous positive airway pressure (CPAP) treatment.
Arecent Swedish study suggests that when OSA patients are more likely to stick with continuous positive airway pressure (CPAP) treatmentwhen they use use a built-in humidifier.
To see what factors might influence whether patients stick with this cumbersome treatment, researchers followed 16,425 people who were prescribed CPAP between 2010 and 2017.
Within one year of starting treatment, 1,527 patients or about 9 % had stopped using their CPAP machines and another 2,395 people or almost 15%were only using it an average of 2.5 hours a night instead of all night as advised.
OSA patients who used CPAP machines with built-in humidifiers from the beginning,however, were 43 % less likely to discontinue CPAP machine.Researchers followed most participants for at least another 2.4 years. During this period, 378 patients died.
This study revealed that upper-airway symptoms,such as nasal congestion (running nose) and mouth dryness are common in patients with OSA on CPAP and are associated with CPAP failure.Humidifiers reduce these symptoms and makes the CPAP treatment more comfortable.
The proportion of patients getting humidifiers at the start of CPAP treatment increased from 30 % at the start of the study to 72 % by the end.
The study found that people who stuck with CPAP were 26 % less likely to die than patients who discontinued treatment.
Women and patients with high blood pressure, on the other hand, were more likely to abandon treatment.
Bariatric and Metabolic surgery is an effective option in reducing the excess weight and also for maintaining the lost weight. This surgery is performed by laparosopic approach. The duration of stay in the hospital is 3.5 days. It is found that after bariatric/metabolic surgery, there is complete resolution of OSA and patients do not require CPAP treatment in the future.
