Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Bariatric surgery is an option for obese individuals who fail to achieve suitable weight loss with lifestyle changes and pharmacological methods. Bariatric surgery can help obese individuals achieve recommended weight reduction and thus improve the course of MAFLD. The additional benefits of bariatric surgery include resolution or amelioration of hypertension, hyperlipidemia and type 2 diabetes and reduction of cardiovascular risk and mortality .
The relation between rate of weight loss after bariatric surgeries and the course of the MAFLD not well studied befor ,So we are aiming to assess the outcome of MAFLD ,TSH in patients undergoing Barietric surgeries and if there is significant correlation of steatosis and rate of weight loss among those patients.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Non-alcoholic fatty liver disease (NAFLD) is defined by macrovesicular steatosis in 5% hepatocytes, in the absence of a secondary cause such as alcohol or drugs. It includes a spectrum of diseases from non-alcoholic fatty liver (NAFL) through to non-alcoholic steatohepatitis (NASH), fibrosis and cirrhosis. The worldwide prevalence of NAFLD is about 25%, ranging from 13% in Africa to 23% in Europe and 32% in the Middle East. Non-alcoholic fatty liver disease (NAFLD) is a recognized complication of obesity.
Recently, it has been proposed to change the name of non-alcoholic fatty liver disease (NAFLD) to Metabolic Associated Fatty Liver Disease (MAFLD) to better reflect the pathophysiology of the disease. MAFLD may better reflect the pathophysiology of this disorder and provides a broad definition for this heterogeneous disorder. The criteria are based on the evidence of hepatic steatosis, plus any of the following three conditions: overweight/ obesity, presence of type 2 diabetes mellitus (T2DM), or evidence of metabolic dysregulation.
Obesity is associated with high TSH levels. Clinical studies have shown a positive correlation between obesity and plasma TSH levels. Furthermore, weight loss in these patients is associated with changes in serum TSH and thyroid hormone levels.
Bariatric surgery is an option for obese individuals who fail to achieve suitable weight loss with lifestyle changes and pharmacological methods. Bariatric surgery can help obese individuals achieve recommended weight reduction and thus improve the course of MAFLD. The additional benefits of bariatric surgery include resolution or amelioration of hypertension, hyperlipidemia and type 2 diabetes and reduction of cardiovascular risk and mortality .
Also The decrease in adipose tissue after bariatric surgery causes changes in plasma fT3, fT4, and TSH levels. obese patients had a decreased thyroid hormone gene expression (especially TSH receptor) in subcutaneous and visceral adipose tissue.
The relation between rate of weight loss after bariatric surgeries and the course of the MAFLD not well studied befor ,So we are aiming to assess the outcome of MAFLD ,TSH in egyption patients undergoing Barietric surgeries and if there is significant correlation of steatosis and rate of weight loss among those patients.
