I hate having to clear my throat. Will dieting help?

Probably not. Being overweight can cause esophageal reflux which could then cause chronic throat clearing but that is quite a stretch. If throat clearing is from chronic sinus drainage, dieting will not help.
Throat clearing. Throat clearing can be from acid reflux. If this acid reflux is caused by being overweight, losing some weight may definitely help relieve some of your throat clearing. Feel better.
