Gastric sleeve surgery, also known as sleeve gastrectomy, has gained popularity as an effective weight loss procedure. As with any surgical intervention, there are potential risks and complications associated with this procedure. One concern that has been raised is whether gastric sleeve surgery can cause liver problems. In order to address this question, it is important to explore the potential relationship between gastric sleeve surgery and liver function.
Background information suggests that obesity can contribute to the development of liver problems, such as non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH). These conditions arise when excessive fat accumulates in the liver, leading to inflammation and liver damage. Gastric sleeve surgery aims to reduce body weight by removing a large portion of the stomach, thereby restricting food intake and promoting weight loss. This weight loss can have positive effects on various metabolic conditions associated with obesity, including improvements in liver function.
Several studies have shown that gastric sleeve surgery can lead to a significant reduction in liver fat content and improvement in liver enzymes associated with NAFLD and NASH. These findings support the idea that gastric sleeve surgery may have a beneficial impact on liver function. However, it is important to note that there is still limited data on the long-term effects of this procedure on liver health, and further research is needed to fully understand the potential relationship between gastric sleeve surgery and liver problems.

Laboratory parameters, fibrosis, and steatosis scores play a significant role in detecting non-alcoholic fatty liver disease (NAFLD) and avoiding invasive liver biopsies. These scores are essential in assessing the severity of the disease and determining the appropriate course of treatment.
Fibrosis and steatosis scores are calculated using specific laboratory parameters. One commonly used formula for fibrosis score calculation is the Fibrosis-4 (FIB-4) index, which includes age, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and platelet count. Another formula is the NAFLD fibrosis score, which incorporates age, AST, ALT, platelet count, and other parameters such as body mass index (BMI) and diabetes status.
Similarly, the NAFLD activity score (NAS), which assesses the degree of steatosis, inflammation, and hepatocyte ballooning, includes laboratory parameters such as ALT, AST, and steatosis percentage.
Before and after surgery, improvements in liver enzymes and fibrosis and steatosis scores are usually observed. Surgery, such as weight loss surgery or liver transplantation, has been shown to reduce liver enzymes like ALT and AST. These improvements are indicative of a reduction in liver inflammation and injury. Additionally, surgical interventions have been found to improve fibrosis and steatosis scores, indicating a reduction in liver fibrosis and fat accumulation.
Ultrasonography is a valuable tool used in assessing liver steatosis, both before and after surgery. Liver steatosis, commonly known as fatty liver disease, is characterized by the accumulation of excess fat in the liver cells. The degree of steatosis can vary, ranging from mild to severe.
Before surgery, ultrasonography is performed to determine the severity of liver steatosis. The ultrasound images show the presence of bright echoes within the liver, indicating an increased fat content. These echoes are graded into different levels of steatosis, such as mild, moderate, and severe, based on the amount of fat accumulation observed.
After surgery, ultrasonography is repeated to monitor the changes in liver steatosis levels. The effectiveness of the surgery in treating liver steatosis can be determined by comparing the pre-surgical and post-surgery ultrasound images. A decrease in the brightness of echoes and a decrease in the grading of steatosis indicate the success of the surgery in reducing the fat content in the liver.
Specific ultrasonographic findings mentioned in the background information include the observation of bright echoes within the liver indicating the presence of fat, and the grading of steatosis into mild, moderate, and severe based on the amount of fat accumulation. The corresponding values may vary depending on the grading system used by the healthcare provider.
Ultrasonography For Liver
Gastric sleeve surgery is a popular weight loss procedure that involves reducing the size of the stomach. While it can effectively help in achieving weight loss, there are potential liver problems associated with this surgery. One such issue is non-alcoholic fatty liver disease (NAFLD), a condition where excess fat accumulates in the liver without alcohol consumption playing a significant role.
A study was conducted to determine the effects of sleeve gastrectomy on NAFLD. The findings revealed that gastric sleeve surgery led to significant improvements in the liver. The weight loss resulting from the surgery resulted in reduced fat accumulation in the liver, leading to improvements in liver function and overall health.
Liver biopsies following gastric sleeve surgery have shown positive changes. These biopsies have revealed reduced fat deposition in the liver, along with improvements in liver inflammation and fibrosis. These improvements are directly linked to the weight loss achieved after the surgery.
However, it is important to note that not all liver abnormalities are completely reversed following the surgery. Portal abnormalities, which are related to blood flow in the liver, remain unchanged even after weight loss. Further research is needed to fully understand these portal abnormalities and their implications.
In summary, gastric sleeve surgery can lead to significant improvements in liver health, specifically in the case of NAFLD. Weight loss resulting from the surgery helps in reducing fat accumulation in the liver and improving liver function. Liver biopsies have shown positive changes, although portal abnormalities remain unaffected. Further studies are required to gain a comprehensive understanding of the implications of gastric sleeve surgery on liver problems. At least for now, gastric sleeve does not seem to cause liver problems.
