Laryngopharyngeal reflux is one possible cause of throat irritation and voice change. Heartburn may or may not occur; these symptoms alone do not prove reflux.
Allergy, vocal strain, infection and other causes need consideration. Redness and swelling on laryngoscopy are not specific. Selected patients need reflux testing or gastroenterology assessment. Reducing late meals and identifying individual food triggers may help. PPIs and other medicines should not be started automatically for every throat symptom; ineffective treatment warrants reassessing the diagnosis.
Assessment covers the mouth, throat and neck; endoscopy or tests are selected when needed. Antibiotics, acid-suppressing medicines and surgery require an appropriate diagnosis. Avoiding smoke and maintaining suitable hydration may reduce irritation.
Difficulty breathing or inability to swallow saliva is an emergency. Persistent one-sided pain, a neck lump, voice changes or unexplained weight loss should be assessed promptly.
This information does not replace an individual consultation. Diagnosis and treatment depend on a medical assessment.
