Chronic gastritis is often silent; when symptoms appear, recurrent upper-abdominal discomfort dominates:
- Vague pain, burning or bloating in the epigastrium or left upper quadrant, sometimes worse or better after meals
- Early satiety: feeling full after only a few bites, preventing completion of a normal meal
- Post-prandial fullness lasting >1 h, scarcely relieved by belching or position change
- Frequent belching, often sour or bitter
- Nausea or occasional retching; vomitus is gastric content without bile or blood
- Upper epigastric heat: a heartburn-like sensation located higher, easily confused with reflux
- Loss of appetite, thick tongue coating, halitosis and other ancillary complaints
Symptoms may be intermittent or persist for weeks, often linked to meals, emotion or fatigue and usually remit at night. Warn the doctor if steady weight loss, repeated vomiting, melena or anaemia appears.
