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

Mental health and metabolic health have long been viewed as two separate fields. Conditions such as depression, bipolar disorder and schizophrenia are generally treated separately from metabolic illnesses like diabetes, obesity and high cholesterol.

However, a recent scientific review published in Nature Mental Health shows that the two conditions are closely linked and mutually influential. The researchers introduce the concept of metabolic psychiatry, an approach that combines mental health treatment with an evaluation of the body’s metabolism.

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 frequently found in patients with psychiatric disorders. These conditions can disrupt the brain’s energy supply, affecting thinking ability, mood and response to treatment.

Conversely, prolonged stress, poor sleep quality and the use of certain psychiatric drugs can increase the risk of obesity, type 2 diabetes and cardiovascular disease. These findings show that physical and mental health cannot be separated in either diagnosis or therapy.

The researchers recommend that patients with mental disorders undergo routine metabolic checks, such as blood sugar levels, lipid profiles, blood pressure and body weight. This step is considered capable of helping detect disease risk earlier whilst also determining more appropriate treatment.

In addition to psychological therapy and medication, lifestyle change is the key. Several recommended measures include adopting a balanced diet, engaging in regular physical activity and improving sleep quality.

A number of metabolism-based therapies, such as metformin and GLP-1 agonists, are currently being studied as complementary treatments for patients with mental disorders. Through the concept of metabolic psychiatry, researchers hope that healthcare services can integrate physical and mental treatment so that patients’ quality of life improves and the risk of chronic disease complications can be reduced.
