My husband has become depressed, has kidney and liver abnormalities, has little energy, has had episodes of dizziness, shortness of breath, headaches, and his personality has changed to much more negative in recent months. He also has some short term memory loss. He is 61. He has high blood pressure, pre-diabetic, high cholesterol. He had a stress test that showed that his heart is fine but his oxygen levels are low and blood pressure high.
