Background: Hyperinsulinemic hypoglycaemia (HH) after Roux-en-Y gastric bypass (RYGB) is rare. Patients typically present with post-prandial hypoglycaemia >1 year after surgery and once weight loss has plateaued. Despite multiple treatment options, the management of these patients remains challenging.Clinical case: A 31-year-old female was referred for bariatric surgery with a BMI of 41.4 kg/m2. In the year preceding the r...

Idiopathic intracranial hypertension (IIH) is characterised by raised intracranial pressure (ICP) and papilloedema, diagnosed primarily in obese women of reproductive age, with the incidence rising with the global epidemic of obesity. Weight-loss lowers ICP and treats IIH. No mechanism explains the link between obesity and raised ICP. We hypothesise that adipose tissue from IIH patients has a metabolically distinct profile that contributes to raised ICP. Our previous data demo...

Polycystic ovary syndrome (PCOS) affects 10% of women and is associated with an increased risk of type 2 diabetes and fatty liver disease. Androgen excess is an important driver of metabolic risk in PCOS. In adipose tissue from women with PCOS, increased activation of androstenedione (A4) to testosterone (T) by the enzyme AKR1C3 results in systemic lipotoxicity. Recent in-vitro studies also demonstrated that T and 11-ketotestosterone (11KT) activate the androgen recep...
