Post-Gastrectomy Diarrhea: Causes and Management

After undergoing surgery for stomach cancer, many patients experience diarrhea, which is often linked to digestive difficulties and imbalances in bowel function. Stomach cancer, a type of malignant tumor, typically requires surgical intervention as a primary treatment. In some cases, a total gastrectomy is performed, removing the entire stomach. Following this procedure, the body's ability to secrete essential digestive fluids is compromised, making it difficult to fully break down and digest food.

Undigested food can irritate the intestines, leading to episodes of diarrhea. Without the stomach's natural digestive processes, food enters the intestines in a less processed state, disrupting normal bowel function and triggering irritation.

Additionally, surgical changes can affect intestinal function, sometimes leading to what is known as post-gastrectomy syndrome. This condition may include symptoms like rapid intestinal transit, also known as "dumping syndrome," where food moves too quickly through the digestive tract. This not only impairs nutrient absorption but also causes increased bowel activity, contributing to frequent loose stools.

Proper dietary management plays a critical role in minimizing these symptoms. Patients are advised to consume easily digestible and nutrient-dense foods that support recovery while reducing gastrointestinal distress. Smaller, more frequent meals can also help regulate digestion and lessen the likelihood of diarrhea.

In conclusion, diarrhea after stomach cancer surgery is a common issue related to digestive insufficiency and intestinal imbalance. With appropriate nutritional support and lifestyle adjustments, many patients can experience significant relief from these postoperative symptoms.
