Are you obese? Beware, for there is a high chance that you can become diabetic. The link between the two has now been scientifically validated.
A team led by Matthew Watt, associate professor at Monash University, discovered that fat cells release a protein called PEDF (pigment epithelium-derived factor) which triggers a chain of events and interactions that lead to development of Type-2 (T-2) diabetes.
"When PEDF is released into the bloodstream, it causes the muscle and liver to become desensitised to insulin. The pancreas then produces more insulin to counteract these negative effects," said Watt.
"This insulin release causes the pancreas to become overworked, eventually slowing or stopping insulin release from the pancreas leading to T-2 diabetes."
"It appears that the more fat tissue a person has the less sensitive they become to insulin. Therefore a greater amount of insulin is required to maintain the body's regulation of blood-glucose," Watt added.
"Our research was able to show that increasing PEDF not only causes T-2 diabetes like complications but that blocking PEDF reverses these effects. The body again returned to being insulin-sensitive and therefore did not need excess insulin to remain regulated."
Watt said identifying the link is a significant breakthrough in explaining the reasons why obesity triggers the onset of T-2 Diabetes, said a Monash University release.
"Until now scientists knew there was a very clear pattern and had strong suspicions that a link existed between the two conditions, but our understanding of the chain of events that are caused by the release of PEDF shows a link," Watt said.
"We already know that weight-loss generally improves the management of blood glucose levels in diabetes patients. We can begin to design new drugs to improve the treatment of Type-2 diabetes," Watt said.
The findings were published Friday in Cell Metabolism.

A decade back obesity-linked deaths were estimated to be about 15 lakh a year in the country.
This number is expected to swell to about two crore a year by 2010. This was stated by experts participating in a one-day Continuing Medical Education programme on ‘Obesity’ held at the Sunrise Hospital in Kochi on Saturday.
Recent studies have shown that obesity is the major preventable cause of deaths worldwide. Lack of interest and paucity of knowledge seems to be the major drawback. Kerala holds the second spot in the country for incidence of obesity, pointed out experts participating in the programme.
Overweight individuals are at high risk for diabetes, high blood pressure, high cholesterol and heart disease.
Experts at the CME pointed out that there are scientific methods to successfully reduce weight that will help prevent diseases like cancer, hypertension, diabetes, stroke and heart disease.
Obesity prevention and treatment should be given top priority in health care and awareness against the disease spread through the educational network. There is also a surgical option called bariatric surgery done through keyhole method that an obese person can undergo.
R. Padmakumar, medical director of Sunrise Hospital convened the programme.
K. Babu, MLA, P. G. R. Pillai, Medical Director, Co-operative Medical College, Abraham Paul, IMA-Kochi president, Shashank Shah, national secretary, Obesity and Metabolic Surgery Society of India were among those who participated in the programme.

Dear Friend,

Many people think that because they're not currently in the hospital or not taking a day off due to sickness, they are "well". But wellness is much more than simply the opposite of being sick; it's a feeling of total health in all areas. Wellness means having the energy to do the things you want to do. It means waking up feeling great, without having to pop medications to start your day. It means playing with your kids and not ending up out of breath. And it means maintaining a healthy weight.
Every one of us has our own reason to lose weight, but it is worthwhile to know why we really need to do so..
