What does it mean if a stroke patient has black stool after taking aspirin, and what should be done?

Cerebral infarction refers to cerebral infarct. Black stool in patients with cerebral infarction after taking aspirin may be caused by physiological factors, or pathological factors such as chronic gastritis or gastrointestinal bleeding. Treatment can be carried out through general management and medication. Specific details are as follows:

I. Physiological Factors

During aspirin use, if the patient consumes dark-colored foods or medications such as animal offal or iron supplements, it may lead to physiologic black stool. Adjust diet appropriately, focusing on light and easily digestible foods.

II. Pathological Factors

1. Chronic Gastritis

This is usually a chronic inflammatory condition of the gastric mucosa caused by factors such as Helicobacter pylori infection or duodenogastric reflux. It may lead to insufficient gastric motility and abnormal bowel movements. Medications such as Weifuchun tablets or teprenone capsules can be taken under medical guidance.

2. Gastrointestinal Bleeding

Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase, thereby suppressing prostaglandin production in the gastric mucosa. This weakens the protective barrier function of the gastric mucosa, damages the mucosal lining, and may cause gastrointestinal bleeding, resulting in black stools. Treatment may include medications such as enteric-coated rabeprazole sodium tablets or enteric-coated omeprazole capsules, taken under medical supervision.

In addition to the above causes, black stool could also result from conditions such as ulcerative colitis, peptic ulcer disease, or gastric cancer. Pay attention to keeping warm and avoid cold exposure to the abdomen. Patients are advised to seek timely medical evaluation and receive standardized treatment under professional guidance to promote recovery.
