Acid reflux & GERD
Reflux is when stomach contents come back up. Persistent reflux can affect the food-pipe and even show up as a cough or hoarseness.
Signs to watch for
- Heartburn, especially after meals or lying down
- Acid or sour taste in the mouth
- Chronic cough, throat-clearing or hoarseness
- Trouble swallowing (see a doctor)
If symptoms are severe or persistent — or you notice bleeding or weight loss — see a doctor promptly.
Why a test helps
A non-invasive saliva test can give objective evidence of reflux, helping your doctor decide when symptoms are unclear.
Tests that may be used
