Question: what does kidney disease look like

Reference:
Chronic kidney disease: Chronic kidney disease, also called chronic kidney failure, describes the gradual loss of kidney function. Your kidneys filter wastes and excess fluids from your blood, which are then excreted in your urine. When chronic kidney disease reaches an advanced stage, dangerous levels of fluid, electrolytes and wastes can build up in your body. In the early stages of chronic kidney disease, you may have few signs or symptoms. Chronic kidney disease may not become apparent until your kidney function is significantly impaired. Treatment for chronic kidney disease focuses on slowing the progression of the kidney damage, usually by controlling the underlying cause. Chronic kidney disease can progress to end-stage kidney failure, which is fatal without artificial filtering (dialysis) or a kidney transplant. Chronic kidney disease care at Mayo Clinic Signs and symptoms of chronic kidney disease develop over time if kidney damage progresses slowly. Signs and symptoms of kidney disease may include: - Nausea   - Vomiting   - Loss of appetite   - Fatigue and weakness   - Sleep problems   - Changes in how much you urinate   - Decreased mental sharpness   - Muscle twitches and cramps   - Swelling of feet and ankles   - Persistent itching   - Chest pain, if fluid builds up around the lining of the heart   - Shortness of breath, if fluid builds up in the lungs   - High blood pressure (hypertension) that's difficult to control Signs and symptoms of kidney disease are often nonspecific, meaning they can also be caused by other illnesses. Because your kidneys are highly adaptable and able to compensate for lost function, signs and symptoms may not appear until irreversible damage has occurred. Make an appointment with your doctor if you have any signs or symptoms of kidney disease. If you have a medical condition that increases your risk of kidney disease, your doctor is likely to monitor your blood pressure and kidney function with urine and blood tests during regular office visits. Ask your doctor whether these tests are necessary for you. Chronic kidney disease occurs when a disease or condition impairs kidney function, causing kidney damage to worsen over several months or years. Diseases and conditions that cause chronic kidney disease include: - Type 1 or type 2 diabetes   - High blood pressure   - Glomerulonephritis (gloe-mer-u-low-nuh-FRY-tis), an inflammation of the kidney's filtering units (glomeruli)   - Interstitial nephritis (in-tur-STISH-ul nuh-FRY-tis), an inflammation of the kidney's tubules and surrounding structures   - Polycystic kidney disease   - Prolonged obstruction of the urinary tract, from conditions such as enlarged prostate, kidney stones and some cancers   - Vesicoureteral (ves-ih-koe-yoo-REE-tur-ul) reflux, a condition that causes urine to back up into your kidneys   - Recurrent kidney infection, also called pyelonephritis (pie-uh-low-nuh-FRY-tis) Factors that may increase your risk of chronic kidney disease include: - Diabetes   - High blood pressure   - Heart and blood vessel (cardiovascular) disease   - Smoking   - Obesity   - Being African-American, Native American or Asian-American   - Family history of kidney disease   - Abnormal kidney structure   - Older age Chronic kidney disease can affect almost every part of your body. Potential complications may include: - Fluid retention, which could lead to swelling in your arms and legs, high blood pressure, or fluid in your lungs (pulmonary edema)   - A sudden rise in potassium levels in your blood (hyperkalemia), which could impair your heart's ability to function and may be life-threatening   - Heart and blood vessel (cardiovascular) disease   - Weak bones and an increased risk of bone fractures   - Anemia   - Decreased sex drive, erectile dysfunction or reduced fertility   - Damage to your central nervous system, which can cause difficulty concentrating, personality changes or seizures   - Decreased immune response, which makes you more vulnerable to infection   - Pericarditis, an inflammation of the saclike membrane that envelops your heart (pericardium)   - Pregnancy complications that carry risks for the mother and the developing fetus   - Irreversible damage to your kidneys (end-stage kidney disease), eventually requiring either dialysis or a kidney transplant for survival As a first step toward diagnosis of kidney disease, your doctor discusses your personal and family history with you. Among other things, your doctor might ask questions about whether you've been diagnosed with high blood pressure, if you've taken a medication that might affect kidney function, if you've noticed changes in your urinary habits, and whether you have any family members who have kidney disease. Next, your doctor performs a physical exam, also checking for signs of problems with your heart or blood vessels, and conducts a neurological exam. For kidney disease diagnosis, you may also need certain tests and procedures, such as: - Blood tests. Kidney function tests look for the level of waste products, such as creatinine and urea, in your blood. - Urine tests. Analyzing a sample of your urine may reveal abnormalities that point to chronic kidney failure and help identify the cause of chronic kidney disease. - Imaging tests. Your doctor may use ultrasound to assess your kidneys' structure and size. Other imaging tests may be used in some cases. - Removing a sample of kidney tissue for testing. Your doctor may recommend a kidney biopsy to remove a sample of kidney tissue. Kidney biopsy is often done with local anesthesia using a long, thin needle that's inserted through your skin and into your kidney. The biopsy sample is sent to a lab for testing to help determine what's causing your kidney problem. Depending on the underlying cause, some types of kidney disease can be treated. Often, though, chronic kidney disease has no cure. Treatment usually consists of measures to help control signs and symptoms, reduce complications, and slow progression of the disease. If your kidneys become severely damaged, you may need treatment for end-stage kidney disease. Treating the cause Your doctor will work to slow or control the cause of your kidney disease. Treatment options vary, depending on the cause. But kidney damage can continue to worsen even when an underlying condition, such as high blood pressure, has been controlled. Treating complications Kidney disease complications can be controlled to make you more comfortable. Treatments may include: - High blood pressure medications. People with kidney disease may experience worsening high blood pressure. Your doctor may recommend medications to lower your blood pressure - commonly angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers - and to preserve kidney function. High blood pressure medications can initially decrease kidney function and change electrolyte levels, so you may need frequent blood tests to monitor your condition. Your doctor will likely also recommend a water pill (diuretic) and a low-salt diet. - Medications to lower cholesterol levels. Your doctor may recommend medications called statins to lower your cholesterol. People with chronic kidney disease often experience high levels of bad cholesterol, which can increase the risk of heart disease. - Medications to treat anemia. In certain situations, your doctor may recommend supplements of the hormone erythropoietin (uh-rith-roe-POI-uh-tin), sometimes with added iron. Erythropoietin supplements aid in production of more red blood cells, which may relieve fatigue and weakness associated with anemia. - Medications to relieve swelling. People with chronic kidney disease may retain fluids. This can lead to swelling in the legs, as well as high blood pressure. Medications called diuretics can help maintain the balance of fluids in your body. - Medications to protect your bones. Your doctor may prescribe calcium and vitamin D supplements to prevent weak bones and lower your risk of fracture. You may also take medication known as a phosphate binder to lower the amount of phosphate in your blood, and protect your blood vessels from damage by calcium deposits (calcification). - A lower protein diet to minimize waste products in your blood. As your body processes protein from foods, it creates waste products that your kidneys must filter from your blood. To reduce the amount of work your kidneys must do, your doctor may recommend eating less protein. Your doctor may also ask you to meet with a dietitian who can suggest ways to lower your protein intake while still eating a healthy diet. Your doctor may recommend follow-up testing at regular intervals to see whether your kidney disease remains stable or progresses. Treatment for end-stage kidney disease If your kidneys can't keep up with waste and fluid clearance on their own and you develop complete or near-complete kidney failure, you have end-stage kidney disease. At that point, you need dialysis or a kidney transplant. - Dialysis. Dialysis artificially removes waste products and extra fluid from your blood when your kidneys can no longer do this. In hemodialysis, a machine filters waste and excess fluids from your blood. In peritoneal dialysis, a thin tube (catheter) inserted into your abdomen fills your abdominal cavity with a dialysis solution that absorbs waste and excess fluids. After a period of time, the dialysis solution drains from your body, carrying the waste with it. - Kidney transplant. A kidney transplant involves surgically placing a healthy kidney from a donor into your body. Transplanted kidneys can come from deceased or living donors. You'll need to take medications for the rest of your life to keep your body from rejecting the new organ. You don't need to be on dialysis to have a kidney transplant. For some who choose not to have dialysis or a kidney transplant, a third option is to treat kidney failure with conservative measures. However, once you have complete kidney failure, your life expectancy generally would be only a few months. Potential future treatments Regenerative medicine holds the potential to fully heal damaged tissues and organs, offering solutions and hope for people who have conditions that today are beyond repair. Regenerative medicine approaches include: - Boosting the body's natural ability to heal itself - Using healthy cells, tissues or organs from a living or deceased donor to replace damaged ones - Delivering specific types of cells or cell products to diseased tissues or organs to restore tissue and organ function For people with chronic kidney disease, regenerative medicine approaches may be developed in the future to help slow progression of the disease. As part of your treatment for chronic kidney disease, your doctor may recommend a special diet to help support your kidneys and limit the work they must do. Ask your doctor for a referral to a dietitian who can analyze your current diet and suggest ways to make your diet easier on your kidneys. Depending on your situation, kidney function and overall health, your dietitian may recommend that you: - Avoid products with added salt. Lower the amount of sodium you eat each day by avoiding products with added salt, including many convenience foods, such as frozen dinners, canned soups and fast foods. Other foods with added salt include salty snack foods, canned vegetables, and processed meats and cheeses. - Choose lower potassium foods. Your dietitian may recommend that you choose lower potassium foods at each meal. High-potassium foods include bananas, oranges, potatoes, spinach and tomatoes. Examples of low-potassium foods include apples, cabbage, carrots, green beans, grapes and strawberries. Be aware that many salt substitutes contain potassium, so you generally should avoid them if you have kidney failure. - Limit the amount of protein you eat. Your dietitian will estimate the appropriate number of grams of protein you need each day and make recommendations based on that amount. High-protein foods include lean meats, eggs, milk, cheese and beans. Low-protein foods include vegetables, fruits, breads and cereals.

Answer: Signs and symptoms of kidney disease may include nausea, vomiting, loss of appetite, fatigue and weakness, sleep problems, changes in how much you urinate, decreased mental sharpness, muscle twitches and cramps, swelling of feet and ankles, persistent itching, chest pain, shortness of breath, or high blood pressure. Signs and symptoms of kidney disease are often nonspecific, meaning they can also be caused by other illnesses. Because your kidneys are highly adaptable and able to compensate for lost function, signs and symptoms may not appear until irreversible damage has occurred. Make an appointment with your doctor if you have any signs or symptoms of kidney disease.
