It has been shown that in chronic kidney disease (CKD), as the Glomerular Filtration Rate (GFR) falls, there is a higher possibility of developing clinical and subclinical hypothyroidism (SCH). With falling GFR, several abnormalities are growing in the thyroid gland at both structural and functional levels. Objective: To estimate the frequency of kuraiveethana noi (subclinical and clinical hypothyroidism) among CKD patients through lab investigation (Thyroid Function Test). Materials and Methods: It is a cross-sectional study carried out on 50 CKD patients reporting at the National Institute of Siddha using a non-random sampling method. After obtaining informed consent, Blood samples were collected from each patient to document their Thyroid profile. Results: Based on their report of thyroid profile, 19 patients had subclinical hypothyroidism, and 6 patients had clinical hypothyroidism. Conclusion: The study concludes that the frequency of subclinical and clinical hypothyroidism is found to be 38% (19 patients) and 12% (6 patients), respectively, among 50 chronic kidney disease patients who visited OPD of Ayothidoss Pandithar Hospital, National Institute of Siddha, Tambaram sanatorium. subclinical hypothyroidism clinical hypothyroidism chronic kidney disease kuraiveethana noi cross-sectional study.
