Obesity
is often triggered and perpetuated by metabolic and hormonal
imbalances that create a viscious cycle of chronic dysglycemia,
reduced
thermogenesis, and altered fat production. This type of chronic
metabolic dysregulation can make it very difficult to lose weight
effectively without first addressing key functional imbalances.
Glucose and insulin are primary players in the etiology of obesity.
The balance between glucose and insulin in the blood can influence
levels of leptin, the "hunger hormone" believed to play
a strong role in regulating human appetite and metabolism.1 Insulin
is released in response to rising blood
glucose, and transports glucose to cells,
where it can be used for fat production.
So it comes as no surprise that upper
body fat and abdominal obesity are strongly
associated with "insulin resistance," a
condition that arises when cell receptors
resist insulin's attempt to deposit glucose,
resulting in hyperinsulinemia, a state
of chronically high levels of insulin.
In fact, some researchers have suggested
that consistently high insulin
levels, both fasting and after eating,
may actually instigate the metabolic
process associated with obesity by increasing
lipid levels in the blood.2-4
Glucose levels are also very important.
Disruption of glucose metabolism
can lead to bouts of hypoglycemia (periods
of low blood sugar), which are
often accompanied by intense cravings
for foods and sweets. This imbalance
may then promote an unhealthy pattern
of binge and/or over-eating that encourages
obesity and further perpetuates more
glucose imbalances.
Chronically high levels of glucose, which
may arise from overeating carbohydrates,
including sugars and alcohol, or from
poor glucose control,
can cause a reaction which alters the
normal structure of proteins in the
blood. This process, called glycation,
creates potentially degenerative products
that are believed to underly the development
of diabetes, accelerated aging, and neurodegenerative
disease. Hemoglobin A1c and fructosamine
are two markers of this process, and
monitoring their levels is crucial for
effectively preventing the cascade of
physiologically destructive events that
may either trigger or arise from chronic
obesity.
The hormones cortisol, DHEA, and IGF-1,
serve as important endocrine markers
for preventing and treating obesity.
Imbalances of these hormones are closely
linked with insulin dysregulation. They
are also directly linked to changes in
the body's fat production. Optimal DHEA
and IGF-1 levels promote increased lean
body mass, increased energy production,
and decreased fat.5-8 Excess
cortisol levels, on the other hand, are
known to stimulate increased blood sugar
production, stimulating fat deposits
in the face, neck and trunk regions,
and an "apple-shaped"
obesity.9-11
The balance between the adrenal hormones
DHEA and cortisol also
ensures that the body is adapting to
stress in a healthy manner. Monitoring
adrenal balance is particularly important
when addressing obesity linked to stress-related
eating disorders.12,13
The Metabolic
Dysglycemia Profile includes fasting
and 2-hour post-prandial analyses of
glucose and insulin tolerance, salivary
assessment of
bioavailable DHEA and cortisol, and fasting
blood assays of hemoglobin
A1c, fructosamine, and IGF-1. The profile
is also available with an optional
add-on lipid profile. By evaluating these
crucial parameters of glycemic
metabolism, the Metabolic Dysglycemia
Profile can serve as a powerful tool
in both the prevention and treatment
of obesity and its related health disorders.
