10. Bowel Movement Changes: GIST’s Unpredictable Tendencies
The regularity and consistency of bowel movements are often indicators of digestive health. But when GIST enters the scene, these patterns can become erratic and unpredictable. Tumors, depending on their size and location, can alter the intestine’s function, leading to constipation or diarrhea.
Constipation, in the context of GIST, isn’t the occasional sluggishness. It’s a persistent difficulty in passing stools, sometimes accompanied by pain. Tumors can physically obstruct the intestines or disrupt their rhythmic contractions, leading to stagnation of fecal matter. The resultant stools are hard, dry, and challenging to expel.
On the other end of the spectrum is diarrhea. GIST tumors, particularly those in the small intestine, can prevent adequate nutrient and water absorption. The unabsorbed water rushes through the intestines, leading to loose, watery stools. This diarrhea isn’t just inconvenient; it can lead to dehydration and electrolyte imbalances.(10)
