Obesity 2026 updateObesity remains one of the most critical and rapidly evolving global health challenges entering 2026, characterized by persistently rising prevalence, expanding clinical consequences, and profound societal and economic impacts. Over the past three decades, the prevalence of overweight and obesity has more than doubled among adults and increased nearly threefold among children and adolescents worldwide, driven by complex interactions between genetic susceptibility, obesogenic environments, sedentary lifestyles, dietary transitions toward energy-dense ultra-processed foods, and broader socio-economic determinants. Projections indicate that, if current trends continue, more than half of the global adult population and a substantial proportion of children will be living with obesity within the next two decades, with particularly rapid increases occurring in low- and middle-income countries undergoing nutritional and urban transitions. This epidemiologic shift has translated into a marked escalation in obesity-related non-communicable diseases, including type 2 diabetes, cardiovascular disease, chronic kidney disease, non-alcoholic fatty liver disease, osteoarthritis, and several obesity-associated malignancies, positioning excess adiposity as a leading contributor to global morbidity, mortality, and disability-adjusted life years. Alongside the growing disease burden, the conceptual framework of obesity has undergone important refinement. While body mass index remains a pragmatic population-level screening tool, its limitations in capturing adiposity distribution and metabolic risk have prompted international efforts to redefine obesity as a chronic, relapsing disease characterized by excess or dysfunctional adipose tissue with heterogeneous clinical expression. Emerging diagnostic paradigms increasingly emphasize waist-based measures, ectopic fat accumulation, and the presence of obesity-related complications, distinguishing pre-clinical obesity from clinically manifest disease and enabling more precise risk stratification and individualized management. Therapeutically, the obesity landscape has been transformed by advances in incretin-based pharmacotherapy, particularly glucagon-like peptide-1 receptor agonists and dual or multi-agonist agents, which have demonstrated unprecedented and sustained weight reduction alongside meaningful improvements in cardiometabolic outcomes. The recent development of effective oral formulations further expands treatment accessibility and has the potential to improve long-term adherence, although challenges related to cost, equity, and health-system implementation remain substantial. Importantly, pharmacotherapy alone is insufficient to address the obesity epidemic, and contemporary management strategies emphasize multimodal, life-course approaches integrating nutritional therapy, physical activity promotion, behavioral and psychological interventions, digital health technologies, and, when appropriate, metabolic and bariatric surgery, tailored to individual risk profiles and comorbidity burdens. At the population level, global policy initiatives increasingly recognize that obesity is not solely an individual responsibility but a systems-driven condition requiring coordinated action across healthcare, education, food systems, urban planning, and regulatory environments to create supportive contexts for healthy living. Concurrently, ongoing research continues to elucidate the complex pathophysiology of obesity, including the roles of genetics, epigenetics, gut microbiota, neuroendocrine regulation, and adipose tissue inflammation, while implementation science seeks to bridge gaps between evidence and real-world practice. Collectively, the 2026 obesity update portrays a paradoxical landscape of escalating global burden alongside unprecedented scientific and therapeutic progress, underscoring that meaningful and sustainable impact will depend on integrating biomedical innovation with structural policy reform, equitable access to care, and sustained public health commitment to reverse current trajectories and improve outcomes across the lifespan.Long-Term Changes of Urinary Exosomal Peptide Levels after Thyroidectomy in Patients with Thyroid Cancer: A Prospective Observational StudyIn this prospective observational study, we investigated whether longitudinal changes in urinary exosomal peptide profiles after thyroidectomy could predict recurrence risk in patients with papillary thyroid cancer, a disease with reported recurrence rates of up to 30%. Adults older than 20 years with newly diagnosed papillary thyroid cancer who had undergone thyroidectomy were enrolled, and urine samples were collected at 12 months after study entry and again one year later for exosomal peptide identification and comparison. Seventy patients were included and stratified according to the interval between surgery and enrollment (<5 years, 5–10 years, and >10 years). During the two-year follow-up after enrollment, no recurrences were observed. Across groups and time intervals, there were no significant differences in serum protein levels or urinary exosomal peptide concentrations, and established high-risk clinical factors showed only weak correlations with these biomarkers. Collectively, these findings delineate the long-term basal fluctuation ranges of serum proteins and urinary exosomal peptides in post-thyroidectomy thyroid cancer survivors, suggesting that biomarker levels remaining within these ranges may be indicative of a lower long-term risk of recurrence in high-risk patients following thyroidectomy.

2026 Update in Primary AldosteronismPrimary aldosteronism (PA) is one of the most prevalent causes for secondary hypertension. Early diagnosis and treatment are mandatory, because patients with PA present markedly higher morbidity of cardiovascular diseases than those with essential hypertension whose blood pressure levels are equally managed. A recently published Endocrine Society Clinical Practice Guideline of PA emphasizes several points. First, screening for PA with serum/plasma aldosterone concentration and plasma renin (concentration or activity) is recommended in all individuals with hypertension. Second, in individuals who screen positive for PA, aldosterone suppression testing is suggested when screening results suggest an intermediate probability for lateralizing PA, but not all cases. Third, in individuals with PA, medical therapy or surgical therapy with the choice of therapy based on lateralization of aldosterone hypersecretion and candidacy for surgery. Fourth, in individuals with PA considering surgery, adrenal lateralization with CT scanning and adrenal venous sampling prior to deciding the treatment approach is suggested. Fifth, in individuals with PA receiving PA-specific medical therapy, mineralocorticoid receptor antagonists (MRAs) are suggested as the dose is titrated by monitoring potassium, renal function, renin (concentration or activity) and blood pressure response during follow-up. We should be aware that diversity exists with respect to aldosterone assays, cut-off values for screening and aldosterone suppression tests, AVS standardization issues, and choice of MRAs depending on countries.
Diagnosis and Management of Adrenal InsufficiencyThe diagnosis and management of adrenal insufficiency presents major clinical challenges. It is often unrecognized, which can lead to adrenal crisis and, if not identified and treated, death. There is a lack of understanding on who is at risk of adrenal insufficiency, how to test for it, and how to manage a life threatening adrenal crisis promptly. While primary and secondary adrenal insufficiency can be regarded as rare conditions, glucocorticoid-induced adrenal insufficiency might be quite common. One should consider glucocorticoid withdrawal syndrome that may occur during glucocorticoid taper. Patient education in raising awareness of glucocorticoid withdrawal syndrome, such as fatigue and reduced appetite, is important when tapering glucocorticoid doses. The symptoms of glucocorticoid withdrawal syndrome may resemble adrenal insufficiency, but HPA axis is normally functional. The degree and persistence of adrenal suppression after cessation of glucocorticoid therapy are dependent on overall exposure and recovery of adrenal function varies greatly among individuals. Upcoming ICE2026/JES2026: Enlightened Endocrinology in Unprecedented TimesWe are pleased to announce that the 22nd International Congress of Endocrinology (ICE2026) and the 99th Annual Congress of the Japan Endocrine Society (JES2026) will be held together at the Kyoto International Conference Center (ICC Kyoto) over five days from June 2 (Tue) to 6 (Sat), 2026 (ICE2026/JES2026).
The International Congress of Endocrinology (ICE) is held every two years, and after 1988 and 2010, this will be the third time that the Congress will be held in Japan. The Japan Endocrine Society (JES) has been actively involved in the International Society of Endocrinology (ISE) since its establishment, and as the JES will celebrate its 100th anniversary in fiscal year 2026, hosting the congress in Japan will be an especially valuable opportunity for JES members.
The theme of ICE2026/JES2026 is: Enlightened Endocrinology in Unprecedented Times. Globally, we are entering an unprecedented era, including digitalization, which has been rapidly accelerated by the experience of the COVID-19 pandemic; a super-aging society, which is mainly faced by developed countries; and extreme weather events, as exemplified by global warming. In the midst of these unprecedented times, we will gather in Kyoto - the birthplace of the Japan Endocrine Society - to discuss the new century of clinical and basic research in various fields of endocrinology.
Participants from all over the world are encouraged to present cutting-edge science from their respective countries, and through active discussions, we hope that you will experience the “Enlightened Endocrinology” of endocrinology in this unprecedented era.
In June, flowers bloom profusely at shrines and temples in Kyoto with the blessings of water, and shrine gardens and hydrangea gardens are open to the public.
We look forward to welcoming participants from all over the world to Kyoto - the ancient capital of Japan - and discussing the future of endocrinology!

Network of AOCE could contribute to the development of ISEThe mission of the International Society of Endocrinology (ISE) is to promote endocrine and metabolic science, education, practice and advocacy worldwide. Around 50 national endocrine societies and 27, 000 representatives belong to the ISE, around 50% of whom are from Asia and Oceania countries. The number of board members in the ISE is proportional to that of membership in each region. Thus, Asian and Oceanian Endocrine societies play an important role in the ISE.
I had served as the president of the Japan Endocrine Society (JES) from 2021 to 2025. During the period, the Korean Endocrine Society (KES) and JES signed the memorandum of understanding, and we just published the Guideline for Cushing disease this year, which were published in Endocrine and Metabolism and Endocrine Journal, the official journals of the KES and JES, respectively. I believe we should extend the collaboration between the KES and JES to other societies in Asian and Oceania Endocrine Society, which will lead to the development of the ISE.
