People with PCOS depression have a higher risk of developing Type 2 Diabetes than non-depressed individuals, according to a new study.
The findings, in the Journal of the American Medical Association, indicated that the relationship between Type 2 Diabetes, which is closely linked to obesity and a sedentary lifestyle, may be somewhat like a two-way highway. Not only can Diabetes lead to depression, but the latter can also lead to Diabetes.
U.S. researchers led by Dr. Sherita Hill Golden of Johns Hopkins University School of Medicine in Baltimore tracked an ethnically diverse group of about 5,000 men and women between ages 45-84 for three years.
They found that people with symptoms of depression were 42% more likely to develop Diabetes by the end of the study than those without such symptoms. They also found that the more serious the symptoms, the higher the risk of Diabetes.
The researchers statistically accounted for factors including obesity, smoking and lack of physical activity, finding that the risk for Diabetes was still 34% higher in patients with depression.
“When we looked at the people in our study who had elevated symptoms of depression, they were more likely to eat more calories, they exercised less and they were more likely to be current smokers. And as a consequence, they were also more obese,” said Dr. Golden, who added that depression also pushes up the levels of stress hormones such as cortisol.
This latter hormone can impair insulin sensitivity and encourage belly fat – risk factors, in their own right, for the onset of Diabetes.
The study also measured the risk for developing depression among people who already had Type 2 Diabetes. Researchers discovered that people who had been treated for this condition were 54% more likely to develop depression symptoms than non-Diabetics.
Regular exercise combined with a balanced, nutritious PCOS diet can help reverse an underlying cause of depression-linked excess weight and obesity, namely the imbalance of blood glucose and insulin called Insulin Resistance, which decreases insulin sensitivity. By reversing Insulin Resistance, it is possible to facilitate PCOS weight loss and improve mood.

As you get older, regular exercise becomes, if anything, even more important if you want to stay PCOS healthy and self-reliant. It’s easy to understand why because exercise improves strength, balance, flexibility and endurance.
Always bear in mind that it’s never too early or too late to incorporate regular exercise into your Polycystic Ovarian Syndrome daily regime. The National Institutes of Health (NIH) recommend four types of exercises for older adults, which have multiple benefits, especially for the heart:
Strength exercises to build muscles and increase your metabolism, which helps to keep your PCOS weight and blood sugar in check.
Balance exercises to build leg muscles, which helps to prevent falls. According to the NIH, American hospitals have 300,000 admissions for broken hips each year, many of them seniors. Falling is often the cause of those fractures.
Stretching exercises can give you more freedom of movement, which will allow you to be more active. Stretching exercises alone, however, will not improve your endurance or strength.
Endurance exercises are any activity – walking, jogging, swimming, biking, even raking leaves – that increases your heart rate and breathing for an extended period of time. Build up your endurance gradually, starting with as little as 5 minutes of endurance activities at a time.

The excess weight that some people with PCOS carry around their middles could be making them fatter than ever, researchers have discovered.
A Canadian team found abdominal fat tissue produces a hormone called NPY, which also prompts the development of cells that turn into fat. High levels of NPY in the brain produce constant feelings of hunger.
Abdominal fat is known to be the most dangerous form of excess weight because it increases the risk of Pre- and Type 2 Diabetes, heart disease and some cancers.
The researchers, from Lawson Health Research Institute linked to the University of Western Ontario, carried out tests on rats which showed that abdominal fat, as well as the brain, produces NPY – also called Neuropeptide Y. It is thought that excessive production of NPY in the brain is one of the main reasons why overweight people eat more food than they should.
But the scientists found NPY in abdominal tissues increases fat cell numbers by stimulating the replication of fat cell precursor cells, which then change into fat cells.
Lead researcher Dr Kaiping Yang said: “This may lead to a vicious cycle where NPY produced in the brain causes you to eat more and therefore gain more fat around your middle – and then that fat produces more NPY hormone which leads to even more fat cells.”
The team will now look at whether NPY produced in the abdomen is released into the body’s circulatory system and therefore affects hunger messages in the brain.

A cup of enriched cocoa may help improve the working of blood vessels in people with Pre- and Type 2 Diabetes, new research suggests.
Doctors prescribed three mugs of specially formulated cocoa a day for a month to a group of Diabetics and found “severely impaired” arteries regained normal function. The German study, featured in the Journal of the American College of Cardiology, suggests chemicals called “flavanols” may be responsible.
People with Pre- and Type 2 Diabetes are at greater risk of cardiovascular problems such as heart disease and strokes, partly due to the effects of high blood sugar on the linings of blood vessels, which stops them being able to expand as much when needed by the body. This can result in higher blood pressure, which can then cause cardiovascular disease.
Cocoa naturally contains flavanols – antioxidant chemicals which also exist in some fruit and vegetables, green tea and red wine.The type of cocoa used in the study cannot presently be found in the shops and is a version enriched with far higher concentrations of the chemicals. Other studies are looking at whether flavanol-enriched chocolate could benefit patients.
Ten Diabetic patients were asked to drink the cocoa three times daily for 30 days, and a special test was used to measure the function of their blood vessels.
The ability of the vessels to expand in response to a demand for extra blood from the body appeared to increase almost immediately.
On average, a healthy person’s arteries could expand by just over 5%, while the average of the 10 Diabetic patients was just 3.3% prior to drinking their first mug of cocoa. Two hours after drinking the cocoa, however, their response averaged 4.8%. Over the 30 days, this improved, to 4.1% even before cocoa, and 5.7% two hours after a mugful.
Excess weight and obesity often uderlie Diabetes. Regular exercise combined with a balanced nutritious diet can help reverse an underlying cause of excess weight and obesity, namely the imbalance of blood glucose and insulin called Insulin Resistance. By reversing this latter condition, you can facilitate PCOS weight loss.
