ABSTRACT
Thyroid hormones affect renal development and physiology. Thyroid hormones have pre-renal and intrinsic renal effects by which they increase renal blood flow and glomerular filtration rate. Hypothyroidism is associated with decreased GFR as well as increased renin angiotensin aldosterone activation. Chronic kidney disease is characterized by low T3 syndrome which is now considered a part of an atypical non-thyroidal illness. CKD patients have raised incidence of primary hypothyroidism and sub-clinical hypothyroidism. Thyroid dysfunction is also associated with glomerulonephritis by a common autoimmune etiology. There are few interactions between thyroid and renal malignancies. A detailed knowledge of these interactions is important for both the nephrologists and endocrinologists for optimal diagnosis and management of the patient.
