Lupus is an autoimmune disease that can attack any part of the body, including internal organs. The kidneys are commonly affected in lupus patients and can lead to the development of lupus nephritis. We’ve put together a list of five of the most common symptoms of lupus nephritis using information from Web MD and kidney.org.
High Blood Pressure
If the blood vessels in the kidneys become damaged due to lupus, they could stop removing waste and extra fluid leading to a build-up of fluid in the body. This extra fluid makes the blood vessels have to work even harder and raises blood pressure. (Source: NIH)
Blood in the Urine
Lupus nephritis can cause the small blood vessels (glomeruli) in the kidneys to bleed which will leach into the urine. Urine may come out pinkish or brown when it’s tinged with blood.
Protein in the Urine
If the urine appears foamy it could be because there is protein present. The glomeruli may also leak protein into the urine.
Swelling in the body, usually the legs, ankles, and feet is due to a build-up of excess fluid which the kidneys are not effectively getting rid of. The swelling can also appear around the eyes.
Sufficient excess fluid which the kidneys are unable to get rid of may result in weight gain.
Having to visit the bathroom more than usual, particularly during the night, could indicate that you have a problem with your kidneys.
