In local classification systems, diseases are often categorized by:

: This is the acute phase of ulceration. Endoscopically, the ulcer base is deep and heavily coated with a thick, yellowish-white slough or exudate (white plaque). The surrounding mucosal margins are prominently swollen, elevated, and erythematous due to severe edema. Active bleeding or exposed, vulnerable blood vessels may sometimes be observed at this point.

Over time, the redness fades as the capillaries decrease, and the area becomes a pale, "white scar" that eventually blends with the surrounding normal mucosa. Summary Table Key Endoscopic Feature Active (A) A1 Thick slough, significant edema, no regeneration A2 Clearer margins, reduced edema, initial regeneration Healing (H) H1 Thin slough, defect reduced by ~50%, more regeneration H2 Minimal slough, defect mostly covered by new tissue Scarring (S) S1 Red scar; no slough; complete epithelial coverage S2 White scar; pale appearance; fully healed sakitamiwa classification

During this stage, therapeutic interventions or natural bodily defenses begin to shrink the dimensions of the wound.

Surrounding edema begins to subside; the "lip-like" sign is less prominent, and the ulcer margins become more cleanly defined. H1

The Sakita-Miwa system divides the lifecycle of an ulcer into : Active (A), Healing (H), and Scarring (S). Each stage is further broken down into two successive substages (1 and 2), creating a highly detailed 6-point scale that captures the precise evolution of the mucosal lesion. [ Active Stage ] ----------> [ Healing Stage

The healing stage is marked by the body's active defense mechanisms and the visual emergence of newly regenerated tissue.

The is the global clinical standard for staging gastric and peptic ulcers. Developed in 1971 by Japanese gastroenterologists Sakita and Miwa, this six-stage endoscopic framework organizes the life cycle of an ulcer into three overarching macro-stages: Active (A) , Healing (H) , and Scarring (S) .

The Sakitamiwa classification is shrouded in mystery, with little information available on its origins and creators. Some speculate that it emerged from within esoteric communities or spiritual traditions, while others propose that it was developed by a single individual with a deep understanding of mysticism and symbolism.

: The ulcer becomes remarkably small and shallow. The white exudate coating is reduced to a tiny central speck or a very thin film. The surrounding regenerative epithelium covers the vast majority of the previous defect, and mucosal folds clearly converge directly toward the healing center. 3. The Scarring Stage (Stage S) Summary Table Key Endoscopic Feature Active (A) A1

The white coating has completely disappeared. The ulcer base is fully covered by new epithelium, but the area remains markedly red due to new capillary growth. S2 (Scar-2 or White Scar):

The classification of disease is the fundamental backbone of medical practice. In biomedicine, classification systems like the ICD-11 categorize diseases based on distinct biological markers. However, in many developing nations and indigenous communities, "Folk Illnesses" persist. These are syndromes recognized only within a specific culture, often lacking direct equivalents in Western nosology.

: The dense white slough coating on the floor becomes noticeably thin. Regenerating epithelium begins migrating from the margins, covering less than 50% of the original ulcer base. Converging mucosal folds can now be clearly seen traveling directly toward the edge of the ulcer crater.
