The difference between chronic gastritis and acute gastritis

The distinction between chronic gastritis and acute gastritis mainly lies in aspects such as onset time, duration of illness, causes, symptom presentation, and cure rates. Acute gastritis has a sudden onset, short course of disease, and obvious and severe symptoms, primarily caused by infections, medications, or stress, often manifesting as upper abdominal pain, nausea, vomiting, and other symptoms. In contrast, chronic gastritis develops gradually, with a longer disease duration, potentially caused by factors such as Helicobacter pylori infection or autoimmune responses. Its symptoms tend to be more persistent and relatively milder, such as upper abdominal discomfort and indigestion. Additionally, the cure rate for acute gastritis is relatively higher, with recovery often achieved within a week with timely treatment, while chronic gastritis has a lower cure rate and requires long-term treatment and management.
