Metformin: A potential aid in reducing delirium risk for diabetic patients

Delirium is a condition characterized by confusion and a lack of awareness of one’s surroundings. It can occur suddenly and is caused by various factors.

Recent research conducted by scientists from Stanford University and other institutions suggests that a commonly used diabetes drug called metformin may help reduce the risk of delirium and improve survival rates.

Metformin has previously been linked to improvements in age-related disorders, including dementia, and lower mortality rates.

Study Findings on Metformin and Delirium Risk

To investigate the impact of metformin on delirium risk, the researchers analyzed data from a study involving 1,404 patients.

The patients were divided into two groups: one group consisted of individuals with type 2 diabetes who were not taking metformin, while the other group consisted of individuals with type 2 diabetes who were taking metformin.

The analysis revealed that patients who had a history of taking metformin had a lower risk of developing delirium compared to those who did not take the drug.

Additionally, patients who took metformin had a lower risk of death.

Implications for People with Diabetes

The findings of this study suggest that metformin may potentially lower the risk of delirium and mortality in individuals with type 2 diabetes. If you have diabetes, it is crucial to discuss your treatment plan with your doctor.

They can recommend appropriate lifestyle changes, medications, or a combination of both to help manage your condition and reduce the risk of complications.

Reducing the Risk of Type 2 Diabetes

While some risk factors for type 2 diabetes are beyond our control, such as age and genetics, there are steps we can take to reduce the risk of developing the condition. Here are some strategies:

Maintain a healthy weight: Losing just 5-10% of body weight can significantly lower the risk of type 2 diabetes.

Exercise regularly: Aim for at least 30 minutes of moderate-intensity exercise, like brisk walking or cycling, most days of the week to improve insulin sensitivity and lower blood sugar levels.

Eat a healthy diet: Focus on a balanced diet rich in fruits, vegetables, whole grains, lean protein, and healthy fats. Limit the consumption of sugary drinks, saturated fats, and trans fats.

Quit smoking: Smoking increases the risk of many health conditions, including type 2 diabetes. Quitting smoking can help lower the risk.

Manage stress: Chronic stress can elevate blood sugar levels and increase the risk of type 2 diabetes. Engage in stress-reducing activities like meditation, yoga, or deep breathing.

Get enough sleep: Aim for 7-9 hours of quality sleep each night to lower the risk of insulin resistance and type 2 diabetes.

Monitor blood sugar levels: Regular check-ups and monitoring of blood sugar levels are essential for individuals with a family history of type 2 diabetes or other risk factors.


The research suggests that metformin, a drug commonly used to treat type 2 diabetes, may reduce the risk of delirium and improve survival rates for diabetic patients.

However, it is important to consult with a healthcare professional to determine the most suitable treatment plan for your specific needs.

Additionally, adopting a healthy lifestyle that includes maintaining a healthy weight, regular exercise, a balanced diet, stress management, and sufficient sleep can help reduce the risk of developing type 2 diabetes and promote overall well-being.

Stay informed about the latest research and work closely with your healthcare provider to make informed decisions about your health.
