The senses of smell and taste play an important role in everyday life. Among other things, they help us detect spoiled food and other potential hazards.
For this reason, researchers believe that changes in these senses should be taken seriously when patients begin treatment with GLP-1 medications.
This is highlighted in a commentary on the study published in JAMA Otolaryngology – Head & Neck Surgery, which was reported by MedPage Today.
The researchers recommend that physicians discuss patients' sense of smell and taste before treatment begins.

Large study
The study is based on medical records from nearly 877,000 people with type 2 diabetes. The participants were divided into two groups.
One group received GLP-1 medication, while the other was treated with other types of diabetes medication. The patients were followed for two years.
The researchers also point out that the findings have limitations.
The data are based on medical diagnoses and patients' self-reported experiences rather than on formal tests of smell and taste.

A small difference
The results show that people treated with GLP-1 medications were more likely to report problems with their sense of smell or taste than those receiving other diabetes medications.
However, the overall risk was only slightly higher, and the actual difference between the two groups was very small.
The researchers therefore conclude that there may be an association, but they also emphasize that further studies using more precise measurements are needed before any firm conclusions can be drawn.
