What causes acute hemorrhagic gastropathy?

Acute hemorrhagic gastropathy is characterized by gastric mucosal damage that leads to bleeding, and it is often associated with exposure to certain irritants or toxins. One of the most common causes is the development of gastric lesions due to the ingestion of toxic substances, such as nonsteroidal anti-inflammatory drugs (NSAIDs), alcohol, or other corrosive agents. These substances can lead to the erosion and ulceration of the gastric mucosa, precipitating acute hemorrhagic changes.

In contrast, chronic digestive disorders tend to lead to more gradual changes and are less likely to cause the sudden mucosal damage seen in acute hemorrhagic gastropathy. Autoimmune therapy generally refers to treatments aimed at modulating the immune response and is not a direct cause of gastric bleeding. Lastly, while viral infections can affect the gastrointestinal tract, they are not typically implicated as a direct cause of acute hemorrhagic gastropathy in the same way toxic substances are. Therefore, the association of gastric damage and bleeding with toxic exposure clearly identifies option B as the correct answer.
