Rationale: Sleeve gastrectomy effectively improves obesity and type 2 diabetes mellitus (T2DM), but nutritional follow-up is essential to optimize outcomes and prevent deficiencies. The impact of a six-month individualized nutritional intervention following laparoscopic sleeve gastrectomy was evaluated in a 37-year-old woman with obesity and T2DM.

Methods: Nutritional status was evaluated using clinical anamnesis, dietary assessment, a food frequency questionnaire, and laboratory screening of nutritional and biochemical markers. An individualized six-month nutritional intervention was implemented, including dietary counselling, optimization of protein intake, hydration guidance, micronutrient supplementation, and lifestyle modification. Anthropometric, body composition, metabolic, and biochemical parameters were evaluated at baseline and after 6 months of intervention.

Results: At the 6-month follow-up, body weight decreased by 30.1%, from 112.7 to 78.8 kg, accompanied by reductions in BMI (40.9 to 28.6 kg/m²), waist circumference (131.0 to 103.5 cm), body fat percentage (46.3% to 32.8%), and visceral adiposity score (11 to 7). Skeletal muscle mass increased from 23.1% to 30.7%. Glycaemic control improved markedly, as evidenced by reductions in fasting plasma glucose from 124.0 to 94.4 mg/dL and HbA1c from 8.0% to 5.67%. Nutritional and inflammatory profiles also improved, as reflected by increases in serum albumin (2.51 to 4.01 g/dL), total protein (5.0 to 6.84 g/dL), vitamin D (14.4 to 30.2 ng/mL), and serum iron (35.0 to 94.6 µg/dL), together with a reduction in C-reactive protein from 1.68 to 0.58 mg/L.

Conclusion: A six-month individualized nutritional intervention following sleeve gastrectomy was associated with substantial improvements in body composition, glycaemic control, nutritional status, and inflammatory profile.
