A colon blockage requires immediate evaluation by your specialist to determine the cause, such as scar tissue from your previous surgery. Treatment depends on whether the blockage is partial or complete. For comfort, doctors may prescribe fluids via IV, pain relievers, and anti-nausea medications like ondansetron. If the blockage is partial, mild laxatives like polyethylene glycol might be used under strict medical supervision. However, medications alone usually do not clear a blockage; procedures like placing a stent (a small mesh tube) to open the colon or surgery are often the most definitive and effective treatments. Please contact your medical team promptly to safely guide your next steps.
