Thank You. My Husband Has Been On Lipior Now For

Thank you. My husband has been on Lipior now for a year. His blood work shows an increase in calcium in his blood. The doctor is talking about Parathyroid issues due to the increase in calcium in his blood.
Also, since on the Lipitor, my husband has severe chronic constipation, and diminished appetite due to this. He takes Citricel daily and Linzess for the constipation. What is going on?
