Weight loss may help reduce sleep apnea

Obese people with sleep apnea may triple the chances of eliminating their sleep problems by losing weight, claims a new study.

More than just loud snoring, sleep apnea can lead to high blood pressure, stroke, cardiovascular disease and a poor quality of life.

"Existing research has been limited by a number of factors, so there are very few studies that show whether the recommended amount of weight loss - about 10 percent - is enough to sufficiently improve sleep apnea," said Gary Foster, director of the Center for Obesity Research and Education.

Foster and colleagues from six other universities recently completed the largest randomized study on the effects of weight loss on sleep apnea in patients with type 2 diabetes.

They found that among patients with severe sleep apnea, those who lost the recommended weight were three times more likely to nearly eliminate the number of sleep apnea episodes compared to those who did not lose weight.

The new study, called Sleep AHEAD, looked at 264 obese patients with type 2 diabetes already enrolled in the Look AHEAD trial, an ongoing 16-site study investigating the long-term health impact of an intensive lifestyle intervention in 5,145 overweight or obese adults with type 2 diabetes. Participants were between 45 and 75 years old.

The 264 participants were broken into two randomized groups: the first received a group behavioral weight loss program developed especially for obese patients with type 2 diabetes, portion-controlled diets, and a prescribed exercise regimen of 175 minutes per week. The second attended three group informational sessions over a one-year period that focused on diabetes management through diet, physical activity and social support.

After one year, members of the first group lost an average of 24 pounds. More than three times as many participants in this group had complete remission of their sleep apnea (13.6 percent compared to 3.5 percent), and also had about half the instances of severe sleep apnea as the second group. Further, participants in the second group only lost about a pound, and saw significant worsening of their sleep apnea, which suggested to Foster and his team that without treatment, the disorder can progress rapidly.

"These results show that doctors as well as patients can expect a significant improvement in their sleep apnea with weight loss," said Foster, the study's lead author.

"And a reduction in sleep apnea has a number of benefits for overall health and well-being," the expert added.

Drink your way to health

It’s time to kick the cola and indulge in some pure fresh water. Especially in a hot and humid city like ours, body water is lost rapidly and requires regular replenishment. Our body consists of about 65 per cent water and just cannot do without it. A mere 2 per cent drop in body water can trigger signs of dehydration, short term memory loss and difficulty in focusing.

Natural healer
Blood circulation is affected when dehydration sets in. The problem only gets worse as dehydration causes the brain to become less active and body to feel tired and fatigued. Water keeps the digestive system in order and flushes out waste products. Water is the natural way towards achieving glowing skin. Drinking acts as a body purifier, removing toxins and waste from your body. “Water forms the basis of wellbeing and cannot be substituted,” says Dr Dilnaz Saini.

Weight loss
Water is an important catalyst for weight loss. “Although most of us take it for granted, water may be the only true ‘magic potion’ for permanent weight loss,” says Dilnaz, “Water suppresses the appetite naturally and helps the body metabolise stored fat.” Studies have shown that a decrease in water intake will cause fat deposits to increase.

Fluid retention
Drinking enough water is the best treatment for fluid retention. Elucidates Dilnaz, “When the body gets less water, it perceives this as a threat to survival and begins to retain every drop.” Water is stored in extracellular spaces (outside the cell). This shows up as swollen feet, legs and hands. The best way to overcome the problem of water retention is to give your body what it needs — plenty of water.

Salt balance
Drinking a healthy amount of water helps the body get rid of unnecessary salts. As the water is forced through the kidneys it takes away excess sodium.

Cold is best
Water preferably should be drunk cold. It’s absorbed into the system more quickly than warm water. “Avoid iced water. Drinking chilled water will quench your thirst fast but the body might actually require a lot more water,” says Dilnaz.
