Snoring and Sleep Apnea Increase Energy Consumption

In attempting to discover the link between sleep apnea and obesity, researchers (primarily in California) looked at adults with symptoms of sleep apnea and evaluated their resting energy expenditures (REE). To determine the amount of energy consumption, indirect calorimetry was used to measure REE for the patients. REE is the number of calories expended over a 24-hour period during a non-active period. Researchers found that REE was positively correlated with the severity of sleep apnea. The more severe a person's sleep apnea, the more calories they burned during sleeping.
How many more calories did sleep apnea sufferers burn? The disparity between the high level and the low level was 373 calories per night. However, this should not be taken as a recommendation that sufferers should avoid treatment for their sleep apnea in the hope of losing weight. As we have already seen, sleep apnea leads to a poor diet, and the amount of additional energy consumption is roughly equal to the amount of additional calories consumed in fat and protein alone. And it doesn't help dissipate the additional cholesterol consumed. And the dangers of sleep apnea, such as high blood pressure and increased risk of stroke and heart attack, mean leaving the condition untreated is a dangerous thing.

Sleep apnea in pregnancy may harm mom and baby

Women who experience sleep apnea during pregnancy may face an increased of risk of health problems, for both themselves and their newborns, a new study suggests.

In the study, babies born to women with obstructive sleep apnea were more likely to be admitted to the neonatal intensive care unit than babies born to women without the condition. All of the women in the study were obese.
In addition, the women with sleep apnea were more likely to develop preeclampsia, a condition of high blood pressure during pregnancy, and to deliver their babies by cesarean section.

Pregnancy complications linked to obesity — such as high blood pressure and gestational diabetes — are better understood than sleep apnea, which is an understudied and under-diagnosed condition in pregnant women, the researchers said.

There is a need for better ways to screen and treat sleep apnea in pregnancy, said study researcher Dr. Judette Louis, an assistant professor of obstetrics and gynecology at the University of South Florida.

People with sleep apnea experience pauses in their breathing during sleep. With obstructive sleep apnea, the pauses are due to a blocked airway. Obesity increases the risk for obstructive sleep apnea because the extra fat tissue can narrow in the inside of the windpipe, according to the National Heart and Blood Institute.

In the new study, the researchers analyzed information from 175 obese pregnant women who were tested for obstructive sleep apnea at home using a portable device.

About 15 percent of participants had obstructive sleep apnea. Those with sleep apnea were more likely to be heavier, and have chronic high blood pressure than those without sleep apnea.

Among those with sleep apnea, about 65 percent required a C-section, while 33 percent of those without the condition required the surgery. Additionally, 42 percent of those with sleep apnea had preeclampsia, compared with 17 percent of those without sleep apnea. The rate of premature births was similar between the groups.

The percentage of newborns requiring admission to the NICU was 46 percent for mothers with sleep apnea, compared with 18 percent for those without sleep apnea. Many of these admissions were due to breathing problems.

The higher rate of NICU admissions for infants born to mothers with sleep apnea may be due to the higher rate of C-sections in this group, the researchers said.

The best way to reduce the risks that come with obesity-related sleep apnea would be to treat obesity before a woman becomes pregnant, although losing weight is often difficult, the researchers said.

Because the study only included obese women, it's not clear whether sleep apnea could have the same effects in women who are not obese.

The study was published online Sept. 20 in the journal Obstetrics & Gynecology.

Boost Your Comfort – Boost Your Success

If you’re nasal or your full face mask rubs your skin and doesn’t fit as well as it should, try the ResMed Gecko Nasal Pad. If chafing was a problem before you’ll look forward every night to your sleep knowing your mask won’t irritate your skin or leak. Another great thing about this products is that it’s affordable (cash price is $24.95 per package). The Nasal Pad is adhesive and silicone-free and can be placed where your mask connects with your nose.

Our patients find that one of the most annoying parts of therapy is the constant presence of the cold, ugly, medical tubing that connects the user's system to the mask or interface. In addition cold hoses and tubing can cause condensation and rain-out disrupting sleep and therapy, you should try either the ResMed tubing wrap or the Respironics tubing wrap. We also have one for the ResMed Slimline tubing as well here.
