Unfortunately, acid reflux can sometimes be a symptom of stomach cancer.

Other symptoms of stomach cancer include:
Burning heartburn or indigestion.
This is common terminology for acid reflux or GERD that we discuss frequently.

Nausea and vomiting
Loss of appetite
Fatigue and weakness
Abdominal pain
Passing blood in vomit, stools or urine.
(This type of bleeding is often caused by gastritis or an ulcer, but it can also be a sign of cancer.)

If you do encounter any of the above symptoms, do not panic, as they are also typical of a diverse range of gastrointestional conditions and not necessarily present due to cancer.

If you feel full after eating only a small meal, I would recommend an upper gastrointestinal endoscopy to eliminate the possibility of stomach cancer.
