Abstract

Purpose
This study aims to explore the feasibility and implications of Ramadan fasting for patients who have undergone laparoscopic sleeve gastrectomy (LSG), assessing impacts on hydration, nutrient intake, weight management, and gastrointestinal symptoms.
Methods
A prospective online survey was conducted among 218 LSG patients and 83 control individuals with obesity who had not undergone surgery. Participants were surveyed before and after Ramadan, providing data on fasting practices, hunger and satiety levels, fluid and nutrient intake, and the occurrence of gastrointestinal symptoms. Statistical analysis was used to compare outcomes between fasting and non-fasting periods and between LSG patients and control participants.
Results
A total of 70.2% of LSG patients completed the entire month of Ramadan fasting, with a significant correlation found between the duration post-surgery and the ability to fast. Fasting LSG patients reported decreased hunger, increased satiety, and significant reductions in fluid and nutrient intake during Ramadan. Weight loss was reported in 90.8% of fasting patients, with an average total weight loss of 7.2%. Gastrointestinal symptoms were mild and manageable.
Conclusion
The majority of LSG patients can successfully fast during Ramadan with appropriate precautions, including adequate fluid and protein intake. The study highlights the need for patient education and tailored nutritional guidance to ensure safe and effective fasting post-LSG. In order to fast for the entire month, patients may be advised to consider postponing surgery for a few months after Ramadan, avoid overeating during non-fasting hours, and ensure sufficient fluid consumption and protein intake during fasting.
