Intestinal and rectal disorders primarily affect motility, absorption, elimination, and fluid balance, making them high-risk conditions for rapid electrolyte disturbances and systemic complications. As nurses, we must understand that many lower GI disorders begin as functional disturbances but can quickly progress to obstruction, ischemia, infection, or perforation if not recognized early. Conditions such as constipation, diarrhea, obstruction, and inflammatory processes directly alter fluid distribution, acid–base balance, and hemodynamic stability, requiring close monitoring. Early identification of abnormal bowel patterns, abdominal changes, and laboratory trends allows timely intervention and prevention of life-threatening complications such as peritonitis or septic shock. Nursing assessment, rapid prioritization, and prevention of secondary complications remain central to safe GI management.
1️⃣ Constipation: Pathophysiology & Clinical Correlation 🚽
🔷 📖 Definition & Risk Factors
< 3 bowel movements/week, hard stool, straining.
↓ fiber intake <25–30g/day → ↓ stool bulk.
