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 study has been published in the Sept. 28 issue of the Archives of Internal Medicine.

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.

A well balanced diet is more important when you are pregnant, since what you eat has to meet your unborn baby’s needs as well as your own requirements. The first three months of pregnancy is important as most of the physical and mental growth of the baby takes place during this time.

The principal organs both external and internal and the nervous system of the baby form within this period. A pregnant women should know that she is not only responsible for herself, but also for the unborn child inside her. The child’s physical and mental development after birth will have a influence of anything seen, thoughts and the food eaten by the pregnant woman.

During the first three months of pregnancy (and preferably before becoming pregnant) a woman needs folic acid. This is one of the B-group vitamins and is also known as vitamin B9. It is important during pregnancy for the creation of the baby’s nervous system.
Good natural sources of folic acid are barley beans, fruit, green vegetables, orange juice, lentils, peas and rice.

During pregnancy, a woman’s body needs more iron than usual to produce all the blood needed to supply nutrition to the placenta. Good sources of iron are green vegetables such as broccoli and spinach, strawberries, muesli and wholemeal bread.

US researchers found that even after the age of 80, smoking increased a person’s risk of developing AMD, age-related macular degeneration, the leading cause of blindness among Americans aged 65 and over, suggesting it is never too late to give up the habit.

The study was the work of lead author Dr Anne Coleman, professor of ophthalmology at the Jules Stein Eye Institute at University of California, Los Angeles (UCLA), and colleagues, and is published in the January issue of the American Journal of Ophthalmology.

AMD causes a darkening and/or blurring of central vision, and prevents you from being able to read, drive and recognize people you know. It is a progressive degeneration of the macula, the centre of the retina, the part of the membrane inside the back of the eye that allows us to see fine details.

Advanced AMD with loss of vision affects about 1.75 million Americans: this figure is expected to rise to just under 3 million by 2020.

Smoking is the second most common risk factor for AMD: age is the first. Coleman and colleagues wanted to find out whether age was linked to the effect of smoking on AMD risk.

Coleman told the press that age was the strongest predictor for AMD, yet most of the research done on the disease only looked at people aged 75 and under.

“Our population was considerably older than those previously studied,” said Coleman.

“This research provides the first accurate snapshot of how smoking affects AMD risk later in life,” she added.

For the study, Coleman and her team compared the retinal photographs of nearly 2,000 women taken at age 78 and 83, looked for signs of AMD and then did logistical regression statistical tests to find out whether smoking affected the women’s risk of developing the disease.

The women were already taking part in a study called the Study of Osteoporotic Fractures, where 45 degree stereoscopic fundus retinal photographs were part of the observations taken at clinic follow ups in year 10 and 15 of the study.

All types of diabetes are treatable, but Type 1 and Type 2 diabetes last a lifetime; there is no known cure. The patient receives regular insulin, which became medically available in 1921. The treatment for a patient with Type 1 is mainly injected insulin, plus some dietary and exercise adherence.

Patients with Type 2 are usually treated with tablets, exercise and a special diet, but sometimes insulin injections are also required.

If diabetes is not adequately controlled the patient has a significantly higher risk of developing complications, such as hypoglycemia, ketoacidosis, and nonketotic hypersosmolar coma. Longer term complications could be cardiovascular disease, retinal damage, chronic kidney failure, nerve damage, poor healing of wounds, gangrene on the feet which may lead to amputation, and erectile dysfunction.
