Women diagnosed with type 2 diabetes developed depression, anxiety and other mental health conditions at markedly higher rates than men, according to a large observational cohort study published in PLOS Medicine on August 25, 2026. In the years after diagnosis, 8.1 percent of women received a mental health diagnosis, compared with 5.3 percent of men.
The Queen Mary University of London team, led by researcher Fabiola Eto, followed 28,720 UK adults for a median of about 6.8 years. All had been diagnosed with type 2 diabetes between 2010 and 2020.
The pattern was mirrored in reverse for physical complications. Men were more likely to develop cardiovascular disease or end-stage renal disease (8.4 percent versus 5.3 percent in women).
Younger women stood out. An analysis reported by news-medical.net highlighted that women aged 16 to 39 showed mental health complications earlier and more often than expected. The authors argue routine psychological screening should be built into standard diabetes care, particularly for younger women.

Why the gap shows up in women
Several biological and social threads run through the finding. In their discussion, the researchers point to internalizing disorders being more common in women, and to gender roles that make women more likely to report symptoms while men underreport because of stigma.
Estrogen's protective effect on blood vessels before menopause also delays cardiovascular problems in women, which can shift the disease burden toward mental health.
There is a metabolic angle too. A narrative review in Diabetes Spectrum from the American Diabetes Association describes depression and diabetes as a bidirectional relationship. Depression can worsen glycemic control, and unstable blood sugar can deepen depressive symptoms.
The screening gap in ordinary care
Mental health screening is already recommended in adult diabetes care. The American Diabetes Association's Standards of Care in Diabetes, 2026 call for annual screening for depression and for anxiety symptoms in people with diabetes, with validated tools such as the PHQ-9 for depressive symptoms and the GAD-7 for anxiety.

In practice, these checks are often skipped during routine follow-ups that focus on blood sugar, blood pressure and medications. That is the gap the new UK study lands on. If a primary care visit never asks the mental health questions, a woman in her twenties or thirties can leave the clinic with well-managed A1C and untreated depression.
Warning signs women with type 2 diabetes should not ignore
Symptoms often overlap with the fatigue and appetite changes that diabetes itself can cause, which is part of why they slip past. Consider raising them at your next appointment if they last more than two weeks:
- Persistent low mood, hopelessness or loss of interest in activities you usually enjoy
- Sleep changes, either insomnia or sleeping much more than usual
- Fatigue that does not lift with rest and is not explained by blood sugar swings
- Difficulty concentrating or making decisions
- Constant worry, restlessness or a racing heart that is not tied to a hypoglycemic episode
- Changes in appetite or weight not linked to a diabetes plan
- Thoughts of self-harm, which warrant immediate contact with a clinician or the 988 Suicide and Crisis Lifeline
For context on scale, the CDC's National Diabetes Statistics Report, updated in January 2026, estimates that 40.1 million Americans were living with diabetes as of 2023. About 90 to 95 percent of adult cases are type 2. For millions of American women, the annual diabetes visit is the most likely place a mental health problem could be caught early.
Patients can ask directly whether their next diabetes review will include a PHQ-9 or GAD-7. If it will not, the ADA guidance is a reasonable point of leverage in the conversation.
