Brief summary

In this study, when patients diagnosed with AN started treatment and their weight increased by 10%; On the other hand, it was aimed to compare the changes in serum adipokine levels observed in morbidly obese patients before bariatric surgery and when they lost 10% of their post-op weight with both anthropometric measurements, biochemical parameters, and values of healthy volunteers.

Detailed description

The most characteristic feature of obesity is the increase in adipose tissue. On the contrary, in anorexia nervosa, there is a decrease in adipose tissue enough to impair neuroendocrine functions. Adipose tissue is formed by loosely binding lipid-filled cells called adipocytes and is now considered an important part of energy metabolism. Adipokines it secretes play a role in many physiological processes of the body such as nutrition, appetite, energy balance, insulin, and glucose metabolism, lipid metabolism, regulation of blood pressure, vascular remodeling, coagulation, and inflammation. Therefore, changes in the amount of body fat in these two patient groups, which are at the two ends of the spectrum, affect both the biochemical parameters and physiological functions of the patients in different ways. It is expected that both adipokine levels and biochemical parameters will approach the values of healthy subjects with a decrease in adipose tissue of clinically morbidly obese patients and an increase in adipose tissue of patients with AN. However, in some studies comparing the parameters of patients with constitutionally weak patients and patients with AN, results contrary to expectations were obtained. In this study, we compared the extent to which weight changes changed adipokines and correlated with biochemical parameters based on healthy and normal-weight volunteers.

Interventions

PROCEDUREBariatric surgery-RYGB

After the creation of a 15-25-cc gastric pouch from the upper stomach, transection of proximal jejunum 70 cm from Treitz ligament also called alimentary tract and anastomosis of the distal end of jejunum to the gastric pouch, and thereafter, anastomosis of the proximal end of transected jejunum to the distal part of the jejunum at 150 cm below the site of transection (jejunoileal anastomosis).

BEHAVIORALDietary intervention

High-calorie medical nutrition program to ensure weight gain
