The symptoms of focal segmental glomerulosclerosis kidney disease include swelling in the hands, legs and feet; foamy urine; high blood pressure and high cholesterol levels, explains WebMD. However, there are few early warning signs of this disease.
FSGS kidney disease manifests in swelling and urine changes because fluid becomes retained in the body, says WebMD. Although this swelling generally occurs in the limbs, it can also appear in the abdomen and around the eyes, becoming painful and causing weight gain. At the same time, urine becomes foamy because high amounts of protein show up in it from the bloodstream. In order to determine if the signs point to FSGS, an individual needs to see a doctor and get a kidney biopsy, kidney ultrasound or glomerular filtration rate test.
FSGS is a disease that hardens the blood vessels in the kidneys and creates scarring, according to WebMD. As a result, the small blood vessels no longer effectively filter out waste products, which can eventually lead to kidney disease. However, this condition can be treated, depending on the cause. For instance, it can occur due to obesity, requiring weight loss, exercise and a low-salt diet to manage the disease. Some other causes include drug use, birth defects or other diseases.
