I recently developed microalbuminaria with good kidney function and creatinine. i have low blood pressure and my weight is normal. i am not diabetic. could low thyroid cause this?

Postural?: The first thing to rule out is orthostatic proteinuria. Void before going to bed; if the first-voided morning specimen is protein-free, perhaps you are just one of those folks who lose a little protein from standing up. In the absence of diabetes or renal dysfunction, microalbuminuria may not be a cause for concern.

Microalbuminuria: Was your microalbuminuria (m) found on a urine analysis? If so, have a 24 hour urine collection for protein (p) to see how much you have in your urine/day, as well drawing some blood work. Apart from diabetes, there are other causes of p that need to be assessed. Have a nephrologist evaluate you to see if the cause of your can be found and treated, if necessary. Your thyroid is not the cause of m.

Not if your: Thyroid has been treated and is back to normal. Causes of increasing urinary protein include poor control of blood sugar, elevated blood pressure and a high protein diet. All are controllable and treatment with ace inhibitors or arb's can decrease urinary protein levels. Check w/your doctor.
