Chronic gastritis and acute gastritis are two different types of stomach inflammation. They affect the stomach lining in unique ways, which is important to understand.

Key Differences

Acute Gastritis:

• Neutrophils: In this type, you see a lot of neutrophils, which are a type of white blood cell. They gather in the stomach lining, showing that there's a quick inflammation happening.
• Epithelial Damage: The stomach lining may show signs of damage. Some surface cells might peel away, and there could be erosion, meaning the top layer is worn down.
• Vascular Congestion: The blood vessels under the stomach lining often look swollen or blocked.

Chronic Gastritis:

• Lymphocytes and Plasma Cells: This kind shows many lymphocytes and plasma cells in the stomach lining. This means the inflammation has been going on for a while.
• Gland Atrophy: Over time, the stomach glands can shrink, which means they produce less stomach acid and enzymes.
• Metaplasia: In chronic cases, some stomach cells might change to look like intestinal cells. This is called intestinal metaplasia.

Conclusion

To sum it up, acute gastritis is marked by quick inflammation and high numbers of neutrophils. Chronic gastritis, on the other hand, involves a slower response with more lymphocytes, shrinking of the glands, and possible cell changes. Knowing these differences helps doctors figure out how to diagnose and treat these conditions.
