Question: Dr. Lilit Baghdasaryan, I had a couple of issues working that were making me feel pretty rough. Since, I have had a 90% blockage stented and a 112 blood sodium that sent me to emergency . so far I am feeling better. Sodium is maintaining at 133. I am insecure with the kidney drs remedy to keep the number up I am taking 2- 1 gram sodium cloride, 2- 20 mg furmoside (lasix) with water restriction of 1500 cc of water . Metroprol has been reduced from 200 mg to 50 mg per day. I think my blood sodium issue may be a side effect of the metoprolol. I had been taking 200 mg for about 25 years and consider I may not have been metablizing it the same as I did when I was younger.
