4-Heartburn
Heartburn, also known as acid indigestion, is a condition whose medical name is pyrosis. This common condition affects at least a quarter of the adult population around the world and can be characterized by an intense burning feeling that originates in the upper gastrointestinal tract and travels upwards towards the throat, mouth, and face. Pyrosis, which can be caused by gastroesophageal reflux, gastritis, and ulcers, is a common complication in patients with stomach cancer. Patients with this condition may expect to experience frequent coughing, sore throat, hoarseness, increased risk of sinus infections, chest pain, and other complications.
