The edema at the ulcer margin begins to subside, and the ulcer base appears cleaner. The white coating may begin to thin. 2. Healing Stage (H1 & H2)

The ulcer base is completely covered by new epithelium, but the area remains red and vascularized. This is a "fresh" scar. sakitamiwa classification

This transition indicates that medical treatment or natural recovery is effectively closing the wound.

This classification is a critical tool in clinical trials to evaluate the efficacy of acid-suppressing drugs like Proton Pump Inhibitors (PPIs) and Potassium-Competitive Acid Blockers (P-CABs) .
