The kidneys filter waste and excess fluid from the blood. Chronic kidney disease occurs when the kidneys lose their function, most often over time. When the kidneys aren’t working properly, dangerous amounts of fluid and waste can build up in the body, causing a range of symptoms that can include fatigue, nausea, swelling, and high blood pressure. Chronic kidney disease can eventually progress to kidney failure.
Electrolytes are minerals that your body needs to function properly. A person's electrolytes can become too high or too low, which is called an electrolyte imbalance or electrolyte abnormality.
Hypertension, or high blood pressure, is a chronic condition where pressure in the arteries that carry blood is elevated. Sustained high blood pressure can cause damage to the body over time and be a major risk factor for heart disease, stroke, kidney disease and more. The condition is diagnosed when measured blood pressure is consistently higher than the norm; lifestyle changes, diet and in serious cases, medication are helpful in controlling it.
