Hyperinsulinemia vs Hyperglycemia - the story of PCOS and Obesity

Posted by Dr. Alison McAllister on Wednesday, 20 January

Hyperinsulinemia vs Hyperglycemia with PCOS and ObesityMany times when I am talking to a practitioner about a patient with PCOS and/or weight issues, I commonly get the response – "His/her blood sugar is normal." However, when we are looking at the health of PCOS and weight-challenged patients, their insulin response is of primary importance, and not just their blood sugar.

When we are fasting, both blood sugar and insulin levels should be at a steady state. Blood sugar is generally between 70-90 mg/dL and insulin levels between 1-8 µIU/mL. When we eat a meal, blood sugar increases. In response, insulin is produced by the pancreatic beta cells to help shepherd glucose into all cells to be used as energy. Within 2 hours, insulin and glucose levels should have essentially returned to normal. Thus, our cells’ exposure to glucose and insulin is only for short blips of time within a 24 hour cycle. Excess glucose that is not used for energy is stored as glycogen in the liver and muscle cells to be used for energy between meals, where it is rapidly available for sudden energy needs such as "fight or flight" situations; but once these stores are full, the body stores extra glucose as fat in adipose cells and we gain weight.

Do Undetected Metabolic Misfortunes Put Patients at Risk for Diabetes & Heart Disease?

Chances are that many of your patients have never heard of insulin resistance or metabolic syndrome. And yet this cluster of conditions and symptoms has become synonymous in the medical literature with dramatically higher risks for diabetes and heart disease.

Hormones and Obesity

Posted by Margaret Groves on Monday, 29 April

b2ap3_thumbnail_96326111.jpgAs the incidence of obesity climbs ever higher in the United States and other industrialized countries around the world, so does the number of theories on what are the causes and solutions to the problem. The science becomes ever more specialized as researchers debate the possibility of a genetic predisposition, a lifestyle effect, a socioeconomic effect, or an ethnic component. People struggling to lose weight receive a plethora of dietary advice – eat low carb, eat more whole grains, eat low fat, eat less meat, eat more protein, etc., and no-one seems to agree on the best diet for weight loss. But are we becoming too focused on the details and losing sight of the big picture about how our bodies really work?
