# Can you thicken coffee for a dysphagia diet?

## Direct answer

Yes. Hot drinks including coffee can be thickened to the prescribed level with a commercial thickener. Xanthan-based thickeners are generally more stable in hot drinks; starch-based ones keep thickening as they stand. Always verify the result with the 10 mL syringe flow test before serving.

## Details

Follow the manufacturer's IDDSI dosing chart for the prescribed level, mix thoroughly, and wait the time the chart specifies before testing. Some thickeners need a few minutes to fully develop.

Temperature matters: a drink that tested right when hot may be thicker once it cools. Test at serving temperature.

## Safety

Use only the food and drink levels prescribed by the person's qualified clinician. Test the actual serving before it is eaten or drunk.
