How bad is it for a lupus person to get diabetes? My husband was diagnosed with lupus a about a two yrs ago. Along with the lupus came: fibromyalgia , autoimmune hepatitis , arthritis , and psoriasis . Lately he has been feeling very thirsty and is constantly peeing. My mother thinks it may be diabetes. Do you think i should take him to a Dr? it is a side effect that has to do with the other sickness? What should i do?
