CT Angography for Prostrate Gland Enlarge problem - #9206

Dear Arun Kumar Srivastava, Since you have type 2 diabetes, prostate enlargement, and high BP, it’s good that your doctor has advised a CT Coronary Angiography as a precautionary check. However, the contrast dye used in the scan is excreted through the kidneys, and as a diabetic patient, you should take some precautions to protect kidney function. Precautions Before & After the CT Coronary Angiography: 1. Hydration is Key • Drink plenty of water before and after the scan to help flush out the contrast dye through urine. • If your doctor allows, you can also take electrolyte-rich fluids (like coconut water or ORS) to support kidney function. 2. Monitor Kidney Function • Since contrast dye can sometimes stress the kidneys, your creatinine and eGFR levels should ideally be checked before the scan to ensure your kidneys can handle it. • If kidney function is borderline, your doctor may suggest IV fluids before or after the test to protect your kidneys. 3. Metformin & Contrast Dye • Metformin should be paused for 24–48 hours after the scan to reduce the risk of lactic acidosis, a rare but serious complication in those with kidney impairment. • Restart Metformin only after your doctor confirms normal kidney function. 4. Monitor for Side Effects • Most people tolerate the contrast dye well, but some may experience nausea, mild headache, or a warm sensation. • Rarely, allergic reactions (rash, itching, or breathing difficulty) may occur. Inform your doctor if you have had any previous contrast dye allergies. 5. Post-Test Care • Avoid excess caffeine, alcohol, or painkillers (NSAIDs like ibuprofen) for a few days, as they can strain the kidneys. • Keep track of urine output—if you notice reduced urination, swelling, or fatigue, consult a doctor immediately. When to Seek Immediate Medical Help: • Severe nausea, dizziness, or breathing difficulty after the scan. • Sudden swelling in feet or reduced urine output (possible kidney strain). Since you are already under cardiology care, it’s good to discuss any concerns with your doctor before the scan.
