After i eat, i always feel like i need to clear my throat. is this a sign of gerd?

Could be: This sounds like a classic symptom for acid reflux. Common symptoms: throat clearing (especially after meals), feeling like something is stuck in the throat, thick mucus, hoarseness, bitter taste in throat, throat irritation. See your local ENT who can use a camera and look at your vocal cords.

Possibly: More likely, you are not clearing the saliva or have some pharyngeal residue (food residue behind the soft palate). Try drinking liquids between each bite. If the problem is more in the throat, an ENT doc can easily look to tell if there is anything more going on.
