Background: Abdominal pain and postbariatric hypoglycemia (PBH) are common after bariatric surgery.

Objectives: This study aimed to explore the potential relationship between abdominal pain, gastrointestinal symptoms, and PBH more than a decade after Roux-en-Y gastric bypass (RYGB) and whether continuous glucose monitoring (CGM) with dietary intervention has an educational role in reducing symptoms.

Subjects: At two public hospitals in Norway (one University Hospital) 22 of 46 invited patients who reported abdominal pain more than weekly took part.

Article Synopsis
  • This study investigates the relationship between adherence to vitamin and mineral supplementation and nutrient deficiencies in patients 12 years post-Roux-en-Y gastric bypass (RYGB).
  • Conducted in Norway, the research analyzed data from 490 patients regarding their supplementation habits and blood nutrient levels, revealing that while a majority adhered to recommendations, deficiencies in key vitamins were still prevalent.
  • The findings suggest that sticking to supplements can lower the risk of deficiencies but may not completely prevent them, particularly for vitamins B, D, and folate.

Background: Symptomatic cholelithiasis requiring treatment is a known side effect after Roux-en-Y gastric bypass (RYGB), but reported rates vary greatly. The objectives for this study were to evaluate the long-term frequency of surgical or endoscopic treatment for symptomatic cholelithiasis 10-15 years after RYGB and its relation to self-reported abdominal pain.

Methods: Observational data from 546 patients who underwent RYGB at public hospitals in Central Norway between March 2003 and December 2009 were analyzed.

Purpose: Roux-en-Y gastric bypass (RYGB) is a well-documented treatment of severe obesity. Attending postoperative educational programs may improve the outcome. The aim of this study was to evaluate whether participation in educational programs lasting 2-3 years after RYGB influences long-term weight loss, weight regain, physical activity, and compliance to multivitamin supplements.

Iron deficiency with or without anemia is a well-known long-term complication after Roux-en-Y, gastric bypass (RYGB) as the procedure alters the gastrointestinal absorption of iron. Iron is essential for hemoglobin synthesis and a number of cellular processes in muscles, neurons, and other organs. Ferritin is the best marker of iron status, and in a patient without inflammation, iron deficiency occurs when ferritin levels are below 15 µg/L, while iron insufficiency occurs when ferritin levels are below 50 µg/L.

Introduction: The promotion of a healthy diet, physical activity and measurement of blood glucose levels are essential components in the care for women with gestational diabetes mellitus (GDM). Smartphones offer a new way to promote health behaviour. The main aim is to investigate if the use of the Pregnant+ app, in addition to standard care, results in better blood glucose levels compared with current standard care only, for women with GDM.

Background: The aim was to examine health benefits and lifestyle factors after Roux-en-Y gastric bypass (RYGB).

Methods: Patients (n = 165) were investigated 2 years after RYGB in relation to psychopharmaceutical drugs, employment status, type 2 diabetes mellitus (T2DM), hypertension, metabolic syndrome (MetS), body weight, physical activity (PA), and energy intake.

Results: Excess weight loss (EWL) was 71.
