Heartburn is acid reflux induced burning sensation traveling up in the retrosternal area, which is relieved by antacid.

Regurgitation is when the stomach contents moves into the throat.

Dysphagia, which is difficult, and/or painful swallowing (alarm symptom!).

Chest pain that may mimic angina and may worsen during a cardiac stress test.

ENT symptoms of hoarseness of voice, chronic morning often one-sided sorethroats, frequent throat clearing, and a feeling of a lump in the throat ("globus hystericus").

Pulmonary Complications: Nighttime asthma, recurrent aspiration pneumonia, especially in elderly, bedridden patients in nursing homes, and patients with chronic pulmonary lung disease.

Barrett's Esophagitis and Carcinoma of the Esophagus are the most severe sequelae of long-term, untreated reflux.
