Your reports show iron deficiency (low serum iron and low transferrin saturation), so iron treatment is definitely required. However, since you already have antral gastritis, some oral iron tablets like Orofer-XT may worsen acidity, pain, or nausea.
Better-tolerated options include:
Iron polymaltose complex / ferric polymaltose syrup or tablets
Carbonyl iron
Liposomal iron
These forms are gentler on the stomach and usually better tolerated in gastritis.
Next Steps
Take iron after food, not on an empty stomach
Continue esomeprazole as prescribed
Avoid tea/coffee 1–2 hours around iron intake
If despite this you still develop gastric discomfort, then IV iron therapy can be considered under medical supervision.
Health Tips
