A new study suggests that some people with type 2 diabetes may be able to safely reduce or even stop certain blood sugar medicines when they improve their daily habits.
The research was published in the Journal of Clinical Medicine and looked at what happens in real-life doctor visits, not in special programs or strict clinical trials.
Type 2 diabetes is a long-term condition in which the body cannot control blood sugar well. Over time, high blood sugar can damage the heart, kidneys, eyes, and nerves.
Because of these risks, many people take medicines such as metformin or insulin to keep their blood sugar in a safe range. These medicines can be very helpful, but they can also have side effects and add to the cost and complexity of care.
In recent years, doctors have become more interested in “deprescribing.” This means carefully reducing or stopping medicines when they may no longer be needed. The idea is not to remove treatment, but to match treatment to the patient’s current health.
If a person’s blood sugar improves because of better eating habits, weight loss, or more physical activity, they may not need as much medication as before.
To explore this idea, researchers reviewed electronic health records from 650 adults with type 2 diabetes. These patients were treated in two primary care clinics that include lifestyle advice as part of routine care. This means doctors regularly talked with patients about diet, exercise, sleep, and stress, rather than only focusing on medicines.
The researchers looked for cases where medicines were reduced or stopped after patients showed clear improvements in weight and blood sugar. They found 41 such cases, which is about 6.3% of all patients in the study.
At first glance, this number may seem small. However, the researchers pointed out that these changes happened during normal doctor visits, not in special programs designed for weight loss or medication reduction. Patients only needed to attend at least two visits to be included in the study. This makes the findings more realistic for everyday healthcare.
Among the patients who reduced their medicines and had follow-up data, there were clear health improvements. On average, body mass index, or BMI, dropped by 2.2 units. Blood sugar levels also improved, with an average decrease of 50.5 mg/dL. These are meaningful changes that can lower the risk of long-term complications.
The most common changes in medication included lowering the dose of metformin, stopping metformin, and reducing insulin doses. Importantly, the study found no evidence that reducing medicines caused harm. Although a few health events were recorded, they were not linked to the deprescribing process.
Lifestyle changes were recorded in just over half of the cases. These changes mainly included healthier eating and more physical activity. The researchers believe that lifestyle improvements may have been more common than recorded, since doctors do not always write down every detail.
The study also raises an important point about the wider impact. In the United States, about 38 million people live with type 2 diabetes. If even a small percentage of these patients could safely reduce their medicines, it could mean millions of people using fewer drugs, spending less money, and having fewer side effects.
This research shows that primary care doctors can play an important role in helping patients improve their health through lifestyle changes and, when appropriate, reduce medication use. It supports a more patient-centered approach, where treatment is adjusted based on real progress.
However, it is important to understand that this study does not mean everyone with diabetes should stop their medicines. The study was based on past records and did not test a specific treatment plan. Each person’s situation is different, and any change in medication should always be guided by a doctor.
In reviewing these findings, the study provides encouraging evidence that lifestyle improvements can lead to real changes in treatment. It highlights the importance of regular follow-up, careful monitoring, and shared decision-making between patients and doctors.
While the percentage of patients who reduced medications was modest, the safety and benefits seen suggest this approach could grow in the future. More research is needed to understand who benefits most and how to apply these findings more widely.
