Even though weight loss surgery is very effective, many people gain weight back afterward. Researchers in Saudi Arabia talked to patients who had this surgery to understand why. They found five main reasons: money problems that make healthy eating hard, stress and emotional struggles, friends and family influencing food choices, lack of support from loved ones, and false ideas about how the surgery works that lead to less exercise. The study shows that patients need better education and support after surgery to keep the weight off long-term.

The Quick Take

  • What they studied: Why do people gain weight back after having weight loss surgery, even though the surgery worked at first?
  • Who participated: Patients from Saudi Arabia who had weight loss surgery and experienced weight regain afterward. The exact number of participants wasn’t specified in the available information.
  • Key finding: Five main controllable factors cause weight regain: money struggles affecting food choices, emotional stress and work pressure, social influences from friends and family, lack of support from loved ones, and misunderstandings about how surgery works that reduce exercise.
  • What it means for you: If you’re considering or have had weight loss surgery, understanding these common challenges can help you prepare. Working with doctors, counselors, and supportive people around you may help prevent weight regain. This research suggests that education and ongoing support after surgery are just as important as the surgery itself.

The Research Details

Researchers used a qualitative research method, which means they had in-depth conversations with patients rather than just collecting numbers. They conducted semi-structured interviews, which are like guided conversations where patients could share their personal experiences and feelings about weight regain after surgery. The researchers then looked for common themes and patterns in what patients said.

This approach is valuable because it captures the real-world experiences and perspectives of people living with the surgery’s outcomes. Instead of testing a hypothesis with statistics, the researchers listened to patients’ stories to understand the complex reasons why weight comes back. The interviews were analyzed carefully to identify the five main themes that kept appearing across different patients’ experiences.

Understanding why weight regain happens from the patient’s perspective is crucial because it reveals controllable factors—things people can actually change—rather than just biological factors they can’t control. This information helps doctors and patients work together to prevent weight regain through better support, education, and lifestyle planning after surgery.

This is a qualitative study, which means it focuses on understanding experiences rather than measuring outcomes with numbers. The strength of this approach is that it provides deep, detailed insights into real patient experiences. The limitation is that the findings are based on a specific group of patients in Saudi Arabia and may not apply equally to all populations. The study doesn’t specify the exact number of participants, which makes it harder to assess how comprehensive the findings are. This type of research is best used alongside other studies to build a complete understanding of the issue.

What the Results Show

The research identified five main reasons why patients gain weight back after surgery:

Economic Challenges: Money problems made it difficult for patients to buy and maintain a healthy diet. Healthy foods are often more expensive, and financial stress made it harder to stick to recommended eating patterns.

Emotional Instability and Work Stress: Patients experienced emotional struggles and work-related stress that interfered with their ability to maintain healthy habits. Stress and emotional problems often led to unhealthy eating patterns.

Social Influence: The patient’s environment—including friends, family, and social situations—encouraged eating behaviors that led to weight gain. Social gatherings and peer pressure made it harder to stick to dietary goals.

Lack of Support: Patients felt unsupported by their social networks. Some family members and friends had negative views about the surgery or didn’t support the patient’s lifestyle changes, making it harder to stay committed.

The fifth theme revealed that patients had false beliefs about how surgery works. Some patients thought the surgery would automatically prevent weight gain without effort, so they reduced their physical activity. This misunderstanding about the surgery’s role led to decreased exercise, which contributed to weight regain. The research emphasizes that ongoing education about realistic expectations after surgery is important for long-term success.

Previous research has focused mainly on biological and genetic reasons for weight regain that people can’t control. This study adds important information by highlighting controllable factors—things patients can actually change with proper support and education. By identifying these modifiable factors, the research suggests that better patient education and support systems could improve long-term outcomes after weight loss surgery.

The study has several limitations to consider: First, the exact number of participants wasn’t clearly specified, making it hard to know how many patients were interviewed. Second, the study only included patients from Saudi Arabia, so the findings may not apply equally to people from other countries or cultures with different economic situations and social support systems. Third, as a qualitative study, the findings are based on patient perceptions rather than objective measurements. Finally, the study doesn’t provide information about how long patients were followed after surgery or whether these factors changed over time.

The Bottom Line

If you’ve had or are planning weight loss surgery: (1) Seek ongoing education about realistic expectations and how to maintain results—this is supported by strong evidence from this research. (2) Build a support network of family, friends, or support groups who understand your goals—the study shows this is crucial. (3) Work with a counselor or therapist to manage stress and emotional eating, as emotional factors significantly influence weight regain. (4) Plan financially for healthy food choices and consider speaking with a nutritionist about budget-friendly healthy options. (5) Maintain regular physical activity as part of your routine, understanding that surgery is a tool, not a complete solution. Confidence level: Moderate—these recommendations are based on patient experiences and should be discussed with your healthcare team.

This research is most relevant for: people considering weight loss surgery, people who have had weight loss surgery and are struggling with weight regain, family members and friends of people who’ve had surgery, healthcare providers who work with bariatric surgery patients, and anyone interested in understanding the psychological and social factors affecting weight management. This research is less relevant for people who haven’t had surgery or those with different medical conditions.

Weight regain typically happens gradually over months to years after surgery, not immediately. The factors identified in this study—financial stress, emotional struggles, and lack of support—are ongoing challenges that develop over time. Seeing benefits from addressing these factors may take several months to a year as new habits and support systems are established. Long-term success requires continuous effort and support, not a one-time fix.

Want to Apply This Research?

  • Track three specific behaviors weekly: (1) Number of days you exercised for at least 30 minutes, (2) Number of meals that followed your post-surgery dietary guidelines, and (3) Stress level rating (1-10) and how you managed it. This captures the key controllable factors identified in the research.
  • Use the app to set up weekly reminders for: stress management activities (meditation, walks, talking to someone), checking in with your support network, and reviewing one educational tip about realistic post-surgery expectations. Create a ‘support network’ feature where you can message accountability partners or join a community of people with similar surgery experiences.
  • Monthly, review your tracking data to identify patterns. For example, do you eat less healthily on high-stress days? Do you exercise less when you feel unsupported? Use these patterns to adjust your support strategies. Set quarterly check-ins to reassess your support system, financial barriers to healthy eating, and emotional well-being. Share this data with your healthcare provider to guide ongoing support.

This research describes patient experiences with weight regain after weight loss surgery and should not be considered medical advice. If you are considering weight loss surgery, have had weight loss surgery, or are experiencing weight regain, please consult with your healthcare provider, surgeon, or a registered dietitian for personalized guidance. The findings are based on qualitative interviews with patients in Saudi Arabia and may not apply equally to all populations. Individual results and experiences vary significantly. This information is intended for educational purposes only and should be used alongside professional medical advice, not as a replacement for it.
