GLP-1 drugs have become some of the most widely prescribed treatments for Type 2 diabetes and weight management. Yet, despite their popularity, not everyone benefits equally. Recent research shows that a person's genes can affect how well GLP-1 medicines control blood sugar. For some patients, these drugs may not work as expected, and their genetics could be one reason why.
This discovery is reshaping how scientists and clinicians think about personalised medicine. If genetic testing can identify patients less likely to respond, doctors may be able to recommend alternative therapies sooner, saving time and reducing frustration.
