From the Guidelines
Bariatric surgery is a viable option for patients with low WBC and slightly high ALT, as it can lead to improved liver function and weight loss, with sleeve gastrectomy being the preferred method, as shown in a recent study 1. When considering bariatric surgery, it's essential to monitor blood work changes, including low WBC count and slightly elevated ALT levels. These changes are often temporary and don't require specific treatment. Low WBC counts may result from nutritional deficiencies, such as protein malnutrition or deficiencies in vitamins like B12, folate, or copper. Ensuring adequate protein intake (60-80g daily) and taking prescribed bariatric supplements can help mitigate these deficiencies. The slightly elevated ALT may be related to rapid weight loss, temporary liver stress, fatty liver resolution, or medication effects. Some key points to consider:
- Staying well-hydrated and following a post-surgical diet carefully can help minimize liver stress and promote weight loss.
- Regular blood work monitoring is crucial to track changes in WBC and ALT levels.
- If the WBC count is severely low (below 3,000 cells/μL) or ALT is more than three times the upper limit of normal, prompt medical attention is necessary.
- Most laboratory abnormalities resolve within 6-12 months after surgery as the body adjusts to anatomical changes and weight stabilizes, as supported by recent guidelines 1.
- Sleeve gastrectomy is the recommended bariatric surgery method for patients with well-compensated cirrhosis or in the setting of liver transplantation, due to its ability to preserve endoscopic access to the stomach and biliary tree, and avoid malabsorption, as highlighted in a recent study 1.
From the Research
Bariatric Surgery and Laboratory Results
- Low white blood cell (WBC) count and slightly high alanine transaminase (ALT) levels are not directly addressed in the provided studies 2, 3, 4, 5, 6.
- However, bariatric surgery has been associated with improvements in metabolic disorders, including non-alcoholic fatty liver disease (NAFLD), which can lead to elevated liver enzymes such as ALT 2.
- The studies focus on the benefits and risks of bariatric surgery, including the prevention of surgical site infections (SSIs) and the safety of the procedure in patients with inflammatory bowel disease (IBD) 3, 4, 5, 6.
- None of the studies provide a clear link between bariatric surgery and low WBC count or slightly high ALT levels, suggesting that more research is needed to understand the relationship between these variables.
Surgical Site Infections and Bariatric Surgery
- The risk of SSIs after bariatric surgery is a concern, and the use of antibiotic prophylaxis is a topic of debate 3, 4, 6.
- Some studies suggest that routine antibiotic prophylaxis may not be necessary for all patients undergoing laparoscopic bariatric surgery, while others recommend its use in high-risk patients 3, 6.
- The choice and dosage of antibiotic prophylaxis can impact the risk of SSI, with inadequate dosing of vancomycin associated with an increased risk of SSI 6.
