Obesity is a global epidemic affecting populations worldwide. Bariatric surgery is currently the most effective treatment for morbid obesity. Nutrition is key in optimizing surgical outcomes by reducing risks and enhancing recovery. Therefore, the aim of this work was to evaluate the nutritional status of patients after bariatric surgery to help identify those at risk for suboptimal outcomes. A convenient sample of 29 adult male and female patients who performed bariatric surgeries was enrolled. There were 86.7% females, 73.3% married, and 71.7% performed gastric sleeve. The results indicate that there is a significant reduction (P<0.05) in body mass index (BMI) after 12 months after operation as compared to the Initial BMI. Patients lost an average of 24.44% after 6 months of the operation while after 12 months the patients lost 49.63% of their weight. The data shows that both waist and hip circumferences decreased, leading to a change in body shape. The significant increase in vitamin D levels post-surgery is a positive finding. There is a significant reduction in nutrient intake among bariatric patients six months after surgery compared with preoperative values. Total caloric intake and all macronutrients decreased markedly (P<0.05), reflecting the substantial dietary restriction and altered gastrointestinal physiology following surgery. Similarly, micronutrients such as calcium, iron, zinc, vitamin B12, and vitamin D showed significant (P<0.05) declines, indicating an increased risk of nutritional deficiencies. Overall, the findings confirm that the profound weight loss achieved through surgery is an effective therapeutic strategy for improving the metabolic health of individuals with severe obesity. The results suggest that patients require concurrent nutritional support to ensure optimal overall outcomes.
