<prompt> If you are a doctor, please answer the medical questions based on the patients description.what dose the combination of these lab results mean or the most important ones inicate:Bun-23.8 Crea-1.5 Co2-29.6 Cal-10.8 Glu-1.4 The Creat has shown a slight increase from 1.2 over last 2-mos. Patient has been on on lithium for 30 yrs  <response>: Hi, The given results of the lab tests are suggestive of chronic kidney disease due to Lithium. Lithium is a medication used in the treatment of bipolar disorder. Its long-term use of lithium may be harmful to organs, such as the kidneys. Kidney damage may include acute sudden or chronic long-term kidney disease and kidney cysts. The amount of kidney damage depends on how long you have been taking lithium. It is possible to reverse kidney damage caused by Lithium early in treatment, but the damage may become permanent over time. So, Lithium should be discontinued and an alternate effective, but a safer medication like atypical antipsychotic should be replaced to treat bipolar disorder. Hope the suggestion given above would be useful. Feedback is appreciated.
