A study published in the journal JAMA Psychiatry, which analysed the prevalence of anorexia and bulimia in 204 countries from 1990 to 2023 by age and sex, has found that the number of cases has risen by 71 per cent. In 2023, an estimated 18.1 million people worldwide were suffering from one of these two eating disorders, of whom 41.2 per cent were young people aged between 10 and 24, and 70 per cent were women. This figure is estimated to rise to 21.8 million by 2050.

In an analysis published by The Lancet Global Health, a panel of specialists urges the medical community to recognize type 5 diabetes as a disease distinct from other types of diabetes. This form of the disease —first described in 1955 and whose name “type 5” was recognized by the International Diabetes Federation in April 2025— affects 25 million people with a low body mass index, mainly in low- and middle-income countries, according to the authors' estimates. People with type 5 diabetes do not produce enough insulin, but their bodies process insulin normally. In addition, they do not usually suffer from ketoacidosis —an acute metabolic complication of diabetes— and their immune systems do not attack the pancreas. 

A study published today in Science Advances suggests that there may be a correlation between having a high body mass index (BMI) in childhood and developing schizophrenia later in life. However, the study also indicates that having a higher BMI in adulthood may be correlated with a lower risk of schizophrenia and obsessive-compulsive disorder.
