Fig. 2: Metabolites associated with bariatric surgery, body mass index and glycaemic control.

Euler diagram of identified metabolites associated with bariatric surgery, weight / body mass index (BMI), type 2 diabetes (T2D) and diet. Diagram shows identified metabolites from serum, urine and faecal biofluids with associations (pFDR < 0.05) to (1) post- versus pre-bariatric surgery, (2) lower weight / BMI, (3) lower glycated haemoglobin (HbA1c) / non-T2D Vs T2D, (4) lower dietary substrate / higher Alternative Healthy Eating Index (AHEI-2010) score. Metabolites with concordant changes are grouped together. Metabolites from each grouping and their associations are detailed in Supplementary Data 1.
