Is there a difference between ulcerative disease and multiple ulcers?

There is a difference between ulcerative disease and multiple ulcers.
1. Ulcerative disease, is a description of the nature of the disease, such as gastrointestinal diseases, ulcerative disease is relative to superficial disease, ulcerative disease damage is deeper, up to the depth of the mucosal muscle layer.
2. Multiple ulcers, is the description of the number of ulcers, multiple ulcers is relative to the unilateral ulcers, multiple ulcers can be more than one ulcer foci, that is, more than one ulcer foci.
Ulcerative disease and multiple ulcers, the former describes the nature of the disease, the latter describes the number of lesions, so the two are fundamentally different, not to be confused.
If ulcerative disease and multiple ulcerative disease are detected on examination, early and standardized treatment is recommended to minimize the adverse effects of the disease.
