Type 2 Diabetes Affects Men and Women Differently, Study Shows

A study of nearly 29,000 people in the United Kingdom has found that type 2 diabetes does not affect men and women equally. The disease creates distinct patterns of complications depending on sex, with men more vulnerable to heart and kidney damage while women face a steeper climb with mental health conditions. The research, published in PLOS Medicine, tracked 28,720 patients newly diagnosed with type 2 diabetes between 2010 and 2020, following their health records over a median of 6.8 years to map which complications emerged and when.

The numbers tell a clear story. Among women, 8.1 percent developed mental health conditions—anxiety, depression, or somatoform disorders—after their diabetes diagnosis, compared with 5.3 percent of men. For men, the risk tilted sharply toward the cardiovascular and renal system: 8.4 percent experienced either heart disease or end-stage kidney failure, versus 5.3 percent of women. High blood pressure emerged as the most frequent complication across both groups, affecting 21.1 percent of men and 20.2 percent of women, suggesting that hypertension is nearly universal in the diabetes experience regardless of sex.

Timing matters as much as type. Men generally developed their complications earlier in the disease course than women did, even though the overall rates were comparable. This gap has biological roots. Men may develop type 2 diabetes at a younger age to begin with. Women, meanwhile, lose a natural protection against heart disease that estrogen provides before menopause, which can shift their disease trajectory later in life. But the mental health burden appears to hit women harder and sooner, raising questions about whether psychological stress accompanies the metabolic shift of diabetes differently across sexes.

The mental health connection carries a darker weight. Researchers found that people who developed mental health conditions after their diabetes diagnosis died earlier than those who did not. Among patients following the same disease pathway, men died on average nine years younger than women. This gap is striking, and it points to a secondary crisis: men at high risk for mental health problems were using healthcare services at lower rates than women in the same risk category. The data suggests men may be slipping through the system, their mental health needs unmet even as their mortality climbs.

Dr. Ravinder Goswami, a senior endocrinologist at AIIMS, cautioned that the picture is more complex than diabetes alone. Women do experience cognitive and neuropsychiatric problems at higher baseline rates than men, independent of diabetes. The disease may amplify existing vulnerabilities rather than create them from scratch. Still, the pattern is clear enough that clinicians need to adjust their approach. Goswami emphasized that doctors managing diabetic patients should keep these sex-specific risks in mind during treatment planning.

The researchers stopped short of claiming causation—the study is observational, meaning it documents associations but cannot prove that diabetes directly causes these complications. They also noted that differences in mental health diagnoses might partly reflect differences in how men and women seek or receive care. Women tend to use healthcare services more consistently and receive longer-term prescriptions, which could mean their mental health conditions are more likely to be formally recorded.

The findings point toward a practical shift in how diabetes care is delivered. Routine mental health screening, particularly for younger women, could catch anxiety and depression early. Men, especially those in their 40s and 50s, might benefit from more aggressive monitoring of their cardiovascular and kidney function. Tracking the sequence and timing of complications—which condition appears first, which follows—could help doctors identify patients at highest risk and intervene before irreversible damage occurs. The study suggests that one-size-fits-all diabetes management is leaving both men and women vulnerable to the specific threats their bodies face.
