The
concept of an empty or full stomach controlling hunger
is wrong.
Physiologists
have proven that the mechanisms involved in the
feeling of hunger are located in the hypothalamus
gland in the brain. A number of elements influence the
hypothalamus that controls the feeling of hunger or
satiety. These are activated according to the rate of
sugar in the blood. If the sugar level is low, hunger
is triggered, if the level is high, then satiety is
activated. There are other elements involved but this
particular one is essential.
There
are receptors in the stomach lining which does play a
limited role in hunger/satiety. It is the brain that
controls the feeling of hunger.
Reducing the size of
the stomach by surgical means is of limited use yet
in patients with morbid obesity (BMI > 40 kg/m2)
or in individuals with BMI from 35-40 kg/m2
with serious co morbidities such as type 2 diabetes or obesity-related joint
disease, the most successful approach to weight loss may be bariatric surgery.
