If you notice changes in your sense of smell while taking a GLP-1 medication, there are several practical steps that may help ease discomfort:
1. Reduce scent exposure temporarily.
Switch to unscented or lightly fragranced body care, cleaning products, and laundry detergents. Avoid heavily perfumed environments where possible.
2. Increase ventilation and fresh air.
Open windows, use fans, or step outside if a smell feels overwhelming. Fresh air can help reset sensory perception.
3. Stay hydrated and eat regularly.
Dehydration and low blood sugar may worsen nausea, which can heighten scent sensitivity.
4. Reintroduce scents gradually.
If you’ve developed an aversion to a particular fragrance, pause exposure for a few weeks and then reintroduce it gently in small amounts.
5. Try structured scent training.
If your smell feels distorted rather than heightened, scent training – a practice involving repeated, mindful exposure to a small set of essential oils – may help recalibrate perception over time. Appellation has a practical guide to scent training or olfactory training here.
6. Speak with your prescribing clinician.
If scent changes are severe, persistent, or interfering with daily life, your clinician may adjust your dosage or offer guidance.
For many people, these sensory shifts are temporary and settle as the body adapts to the medication.
7. Opt for cold or room-temperature foods.
Hot foods release more volatile aromatic compounds, which can intensify smells. Choosing cooler meals may reduce scent strength and help minimise nausea.
