Abstract
One hundred patients with non ulcer dyspepsia with history of chronic tobacco chewing were examined endoscopically to assess the effect of tobacco ingestion on the gastric mucosa. Gastric erosions were seen in 20 patients in the fasting state. The remaining 80 patients in whom gastroscopy did not reveal erosions were subjected to repeat gastroscopy after tobacco ingestion. In 40 patients, endoscopy was repeated 30 minutes after 200 mg of tobacco ingestion (Group I) and in another 40 patients endoscopy was repeated 1 hour after 400 mg of tobacco ingestion (Group II). Eleven patients (27.5%) in Group I and 19 (47.5%) in Group II developed gastric erosions. Erosions were observed mainly along the lesser curvature, and in the fundus and the body of stomach. Gastric pH, determined after tobacco ingestion, was 2.4 +/- 0.43 in patients with erosions and 3.0 +/- 0.67 in patients without erosions. It is concluded that tobacco ingestion produces dose-dependent damage to the gastric mucosa as seen on endoscopy. Hence, history of tobacco ingestion should always be asked for in patients with gastric erosions.
