Mental and Metabolic Disorders Should Be Treated Together, Here's Why

Mental health and metabolic health have long been viewed as separate fields. Conditions such as depression, bipolar disorder, and schizophrenia are typically treated independently of metabolic diseases like diabetes, obesity, and high cholesterol. However, a recent scientific review published in Nature Mental Health indicates that these two areas are closely linked and influence each other. The researchers introduce the concept of ‘metabolic psychiatry’, an approach that combines mental health treatment with metabolic evaluation. This approach is based on evidence that metabolic disorders can affect brain function, while mental disorders can also increase the risk of metabolic disease. The review explains that insulin resistance, impaired fat metabolism, chronic inflammation, and mitochondrial dysfunction are often found in patients with psychiatric disorders. These conditions can disrupt the brain’s energy supply, affecting cognitive ability, mood, and response to treatment. Conversely, prolonged stress, poor sleep quality, and the use of certain psychiatric medications can increase the risk of obesity, type 2 diabetes, and cardiovascular disease. These findings suggest that physical and mental health cannot be separated in diagnosis or therapy. Researchers recommend that patients with mental disorders undergo routine metabolic screening, including blood sugar levels, lipid profiles, blood pressure, and weight. Such steps could help detect disease risks earlier and determine more appropriate treatment. In addition to psychological therapy and medication, lifestyle changes are a key component. Several metabolic therapies, such as metformin and GLP-1 agonists, are also being studied as adjunctive treatments for psychiatric patients. Through the concept of metabolic psychiatry, researchers hope that healthcare services can integrate physical and mental treatment to improve patients’ quality of life and reduce the risk of chronic disease complications.
