9. Renal disease symptoms
In many cases of lupus, patients experience a severe involvement of their kidneys and may end up with acute or chronic renal failure. There are many variations and degrees of renal diseases in lupus, and some develop asymptomatically over the course of many years until the damage becomes irreversible.
Symptoms of a possible renal failure include hypertension that is difficult to control with medications, blood in the urine, fluid retention with swelling in the lower extremities, weight gain, and alterations of lipid levels in the blood. Notify your doctor if you find any of these in combination with a diagnosed type of lupus or any suspicion of this disease.
