Three years back,during routine annual blood work, my S.Creatinine was found elevated to 1.4 (ref value 1.0) with no symptoms felt by me. doctor concluded Hypertensive Nephropathy,stable. No change to the status till now. This year , another Dr suggested Thyroid tests too,and I was found to have sub clinical Hypothyroidism with Tsh at 16.5 (max 4.5).I was put on thyroxine 25 mg and after 3 months TsChatDoctore down to 8.0. the dr is probably planning increase the dosage by 12.5 mg to further bring Tsh to a normal range. My doubt is whether this aggressive treatment to bring down will affect my Kidneys adversely or is it going to be good for my kidneys under the circumstance of my being a CKD patient ?
Hello, As a urologist, I can understand your anxiety. Hypothyroidism doesn't affect the kidneys or its function. Thyroxine dosage is very safe in any strength for the kidneys. But till the TSH is normal, till need to be increased gradually. Your creatinine is borderline normal. You should keep your BP normal. Check it regularly. Hope I have answered your query. Let me know if I can assist you further.
