Kidney Failure

 


  • Your kidneys are a pair of organs located toward your lower back. One kidney is on each side of your spine. They filter your blood and remove toxins from your body. Kidneys send toxins to your bladder, which your body later removes toxins during urination.
  • Kidney failure occurs when your kidneys lose the ability to sufficiently filter waste from your blood. Many factors can interfere with your kidney health and function, such as:
    • toxic exposure to environmental pollutants or certain medications
    • certain acute and chronic diseases
    • severe dehydration
    • kidney trauma
  • Your body becomes overloaded with toxins if your kidneys can’t do their regular job. This can lead to kidney failure, which can be life-threatening if left untreated.
Symptoms of kidney failure
  • Usually someone with kidney failure will have a few symptoms of the disease. Sometimes no symptoms are present. Possible symptoms include:
    • a reduced amount of urine
    • swelling of your legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste
    • unexplained shortness of breath
    • excessive drowsiness or fatigue
    • persistent nausea
    • confusion
    • pain or pressure in your chest
    • seizures
    • coma
Early signs of kidney failure
  • Symptoms of early stage kidney disease may be difficult to pinpoint. They’re often subtle and hard to identify. If you experience early signs of kidney disease, they may include:
    • decreased urine output
    • fluid retention that leads to swelling in limbs
    • shortness of breath

  • Kidney failure can be the result of several conditions or causes. The cause typically also determines the type of kidney failure.
  • People who are most at risk usually have one or more of the following causes:
Loss of blood flow to the kidneys
  • A sudden loss of blood flow to your kidneys can prompt kidney failure. Some conditions that cause loss of blood flow to the kidneys include:
    • a heart attack
    • heart disease
    • scarring of the liver or liver failure
    • dehydration
    • a severe burn
    • an allergic reaction
    • a severe infection, such as sepsis
  • High blood pressure and anti-inflammatory medications can also limit blood flow.
Urine elimination problems
  • When your body can’t eliminate urine, toxins build up and overload the kidneys. Some cancers can block the urine passageways, such as:
    • prostate (most common type in men)
    • colon
    • cervical
    • bladder
  • Other conditions can interfere with urination and possibly lead to kidney failure, including:
    • kidney stones
    • an enlarged prostate
    • blood clots within your urinary tract
    • damage to your nerves that control your bladder
Other causes
  • Some other things that may lead to kidney failure include:
    • a blood clot in or around your kidneys
    • infection
    • an overload of toxins from heavy metals
    • drugs and alcohol
    • vasculitis, an inflammation of blood vessels
    • lupus, an autoimmune disease that can cause inflammation of many body organs
    • glomerulonephritis, an inflammation of the small blood vessels of the kidneys
    • hemolytic uremic syndrome, which involves the breakdown of red blood cells following a bacterial infection, usually of the intestines
    • multiple myeloma, a cancer of the plasma cells in your bone marrow
    • scleroderma, an autoimmune condition that affects your skin
    • thrombotic thrombocytopenic purpura, a disorder that causes blood clots in small vessels
    • chemotherapy drugs that treat cancer and some autoimmune diseases
    • dyes used in some imaging tests
    • certain antibiotics
    • uncontrolled diabetes

  • There are several treatments for kidney failure. The type of treatment you need will depend on the reason for your kidney failure.

Dialysis

  • Dialysis filters and purifies the blood using a machine. The machine performs the function of the kidneys. Depending on the type of dialysis, you may be connected to a large machine or a portable catheter bag.
  • You may need to follow a low-potassium, low-salt diet along with dialysis.
  • Dialysis doesn’t cure kidney failure, but it can extend your life if you go to regularly scheduled treatments.

Kidney transplant

  • Another treatment option is a kidney transplant. A transplanted kidney can work normally, and dialysis is no longer needed.
  • There’s usually a long wait to receive a donor kidney that’s compatible with your body. If you have a living donor the process may go more quickly.
  • You must take immunosuppressive drugs after the surgery to prevent your body from rejecting the new kidney. These drugs have their own side effects, some of which are serious.
  • Transplant surgery might not be the right treatment option for everyone. It’s also possible for the surgery to be unsuccessful.
  • Talk with your doctor about whether you’re a good candidate for a kidney transplant.

  • There are steps you can take to reduce your risk for kidney failure.
  • Follow directions when taking over-the-counter medications. Taking doses that are too high (even of common drugs like aspirin) can create high toxin levels in a short amount of time. This can overload your kidneys.
  • Many kidney or urinary tract conditions lead to kidney failure when they’re not properly managed. You can help reduce your risk for kidney failure by:
    • maintaining a healthy lifestyle
    • following your doctor’s advice
    • taking prescribed medicine as directed
    • treating common causes of kidney failure, such as high blood pressure and diabetes
  • If you have any concerns about your kidneys, don’t hesitate to reach out to your doctor.

Every thing you need to know about Dialysis

  The kidneys filter your blood by removing waste and excess fluid from your body. This waste is sent to the bladder to be eliminated when you urinate. Dialysis performs the function of the kidneys if they’ve failed. According to the National Kidney Foundation, end-stage kidney failure occurs when the kidneys are performing at only 10 to 15 percent of their normal function. Dialysis is a treatment that filters and purifies the blood using a machine. This helps keep your fluids and electrolytes in balance when the kidneys can’t do their job. Dialysis has been used since the 1940s to treat people with kidney problems. Why is dialysis used? Properly functioning kidneys prevent extra water, waste, and other impurities from accumulating in your body. They also help control blood pressure and regulate the levels of chemical elements in the blood. These elements may include sodium and potassium. Your kidneys even activate a ...

Health Benefits of Pomegranate

Categorized as a berry, the pomegranate fruit is about 5–12 cm (2–5 inches) in diameter. It is red, round and looks kind of like a red apple with a flower-shaped stem. The skin of the pomegranate is thick and inedible, but there are hundreds of edible seeds within. Each seed is surrounded by a red, juicy and sweet seed covering known as an aril. The seeds and arils are the edible parts of the fruit — eaten either raw or processed into pomegranate juice — but the peel is discarded. 1. Pomegranates Are Loaded With Important Nutrients Pomegranates have an impressive nutrient profile — one cup of arils (174 grams) contains (2): Fiber: 7 grams Protein: 3 grams Vitamin C: 30% of the RDI Vitamin K: 36% of the RDI Folate: 16% of the RDI Potassium: 12% of the RDI The pomegranate arils are also very sweet, with one cup containing 24 grams of sugar and 144 calories. 2. Pomegranates Contain Two Plant Compounds With Powerful Medicinal Properties Punicalagins Punicalagins are extremely potent antio...

Slapped Cheek Disease

Slapped cheek syndrome (fifth disease) is common in children and should clear up on its own within 3 weeks. It's rarer in adults, but can be more serious. Symptoms may include: -a high temperature of 38C or more -a runny nose and sore throat -a headache How long it lasts: The cheek rash normally fades within 2 weeks. The body rash also fades within 2 weeks, but sometimes comes and goes for up to a month, especially if you're exercising, hot, anxious or stressed. Adults might also have joint pain and stiffness. This can continue for many weeks, even after the other symptoms have gone. How slapped cheek syndrome is spread? It's hard to avoid spreading slapped cheek syndrome because most people do not know they have it until they get the rash. You can only spread it to other people before the rash appears. Slapped cheek syndrome is caused by a virus (parvovirus B19). The virus spreads to other people, surfaces or objects by coughing or sneezing near them. To reduce the risk of...
