Hello, It s unlikely for bladder and colon issues to appear almost a year after a colonoscopy. Colonoscopies are generally safe. During the procedure if colonoscopy identified polyps, or any other issue, it s possible those underlying conditions have progressed, potentially affecting your bladder or colon function. If pelvic floor muscles were affected by stress, strain, or other conditions, you could experience symptoms in both areas. If conditions like IBS or inflammatory bowel disease go undiagnosed it may worsen over time and could contribute to both bladder and bowel symptoms. Get clinically examined by a GP, get all the required investigations done. Also, get urinalysis or bladder imaging tests done to rule out UTIs or structural issues. A follow-up colonoscopy or imaging study (e.g., CT scan) might help assess colon health. Take care. Hope I have answered your question. Let me know if I can assist you further.
