You're said to suffer from the problem of acute kidney failure if your kidneys suddenly stop working and lose their ability to eliminate waste materials including excess fluids and salts from the blood. The condition usually develops quickly over a few days or even a few hours. When this happens, waste materials accumulate in your blood, disrupting the chemical balance of your bloodstream.

So, what causes this problem?

Acute kidney failure can occur because of any one of these reasons:

1. A drop or slowdown of blood flow to the kidneys - Adequate blood circulation to the kidneys is of great importance as without it the kidneys may end malfunctioning. If blood flow to the kidney is hampered, a part of or the entire kidney may die. You may suffer from acute kidney failure if blood flow to the kidneys gets impaired due to conditions like

Heavy blood loss
Sepsis (body's inflammatory reaction to an infection, which can bring about organ failure, tissue damage, and death)
Injury
Use of certain drugs
Dehydration
Burns
Heart disease
2. Urinary obstructions - A sudden blockage that hampers your kidney's ability to eliminate urine can also bring about acute kidney failure. When this happens, it leads to a build up of toxins in the body, causing an overload of the kidneys. Conditions that bring about this urinary obstruction include:

Cervical cancer
Colon cancer
Bladder cancer
Kidney stones
Enlarged prostate
Prostate cancer
3. Disease within the kidneys - Even instances of clotting within the blood vessels of the kidneys can lead to acute kidney failure. This is because if the movement of blood cells within the blood vessels gets hampered, kidneys are not able to filter out toxins from the body. The conditions and diseases that may cause clotting, and subsequently damage to the kidneys include:

Scleroderma (an autoimmune disease that affects connective tissues and skin)
Build-up of cholesterol deposits
Glomerulonephritis (an inflammatory condition of the kidney's ball-shaped structures called glomeruli)
Hemolytic uremic syndrome (a condition that occurs due to untimely death of red blood cells)
Lupus (a disorder of the body's immune system that brings about damage to the body's own organs and tissues)

3 Causes of Acute Kidney Failure!

Most people believe kidneys to be organs solely responsible for the filtration of blood and production of urine. But the truth is that the kidneys perform a host of vital functions in the body which include regulation of blood pressure, blood volume, and blood Ph. Around half of the individuals affected by lupus suffer from kidney problems, and the most affected part is the glomerulus whose function is filtering substances from the blood.

Effects of lupus nephritis on the kidneys
Lupus itself doesn t lead to kidney infection or inflammation. But lupus nephritis, which is the Systemic lupus erythematosus (SLE) that affects the kidneys and the medications used for treating the condition tend to suppress the immune system. It makes the person affected with lupus vulnerable to the infections of various types. It is one of the most severe conditions of that could be encountered by a person wherein the immune system starts attacking various parts of the body as they would tackle a disease.

Lupus nephritis makes the kidney unable to remove the waste materials effectively from the blood. This leads to loss of control over the amounts of fluids regulating in the body. As a result, an abnormal amount of waste can build up in the blood resulting in edema or swelling.

When left untreated, these conditions can cause scarring along with permanent damage to the kidneys and end-stage renal disease. When a person has end stage renal disease, he or she needs regular filtering of the waste products of the body with the help of a machine. In severe cases, a kidney transplant may be required to ensure that at least one kidney is working properly.

Individuals who are susceptible to developing lupus nephritis:
A person with lupus may see the symptoms of lupus nephritis within 5 years and the people aged between 20 and 40 years are most vulnerable to it. In some common instances, it is seen that lupus nephritis is leading to unexplained weight gain along with swelling and puffiness in different parts of the body such as ankles, hands, eyelids, legs, and feet. During the first stages, these symptoms are often ignored which causes worsening of the condition. The urine may also become frothy or foamy with a reddish tinge in it. It is estimated that about 40 percent of children having lupus would develop kidney complications. Lupus nephritis may also cause increased urination, blood in the urine and elevated blood pressure.

If you have lupus, it is imperative to consult with a nephrologist. Testing a sample of the urine can help in showing the problems in the functioning of the kidneys. Your doctor will advise you about the diagnostic tests that can help in determining whether the disease has progressed to severe levels and start with the treatment process accordingly.

How Does Lupus Nephritis Affect Your Kidneys?

The main task of the kidneys is to balance the electrolytes in the blood and maintain the pH homeostasis. The kidneys also remove waste products from the blood. Infections in the kidney aren t uncommon and affect women (majorly pregnant women) and children below the age of two in most conditions.

Kidney infections are of two types:

Uncomplicated kidney infection: The infections in this condition are minor and can be cured with minimal medication.
Complicated kidney infection: These infections are more complex and serious as compared to the uncomplicated ones.
If not treated on time, kidney infection can prove to become a serious condition and lead to various complications including kidney damage and blood poisoning (sepsis).

The most common causes of kidney infections are:

Weak immune system: If you have a weak immune system, you are prone to getting a bacterial or fungal infection on the surface of your skin which eventually enters the bloodstream. The infection might right reach the kidneys and cause an infection there.
Bacteria entering from the urethra: The pathogen which causes an infection can enter the body through the urethra and multiply in the bladder. The infection spreads to the kidneys and causes renal infection.
Kidney stones: People diagnosed with kidney stones are at a very high risk of developing kidney infections. Kidney stones are caused because of a build-up of dissolved minerals in the inner lining of the kidneys.
Enlarged prostate: Men with an excessively enlarged prostate are prone to developing kidney infections as compared to men with a normal-sized prostate.
Intercourse: Engaging in sexual (anal or vaginal) intercourse with an infected person can be a major reason for kidney infection as the bacteria can enter the body through the anus or the vagina and affect the kidneys.
It is not difficult to detect infection in the kidneys as they have very visible symptoms. A few symptoms of kidney infection are:

Excessive back pain
Sudden chills or fever
Nausea and puking
Blood in the urine
Pain while urinating

Kidney Infections - Factors That Put You At Risk!

When your kidney function falls below a certain point, it is referred to as a kidney failure or renal failure. Fortunately, you can still continue to lead a normal life with the right treatment for renal failure. Here are the three best treatments that you can choose depending on your condition and lifestyle:

1. Dialysis: Dialysis is the process that takes over the function of your kidneys to filter out the waste from your blood and maintain the proper balance of chemicals in the blood. You may use dialysis for many years or as a short-term treatment while waiting for a kidney transplant. Dialysis is not a cure for kidney disease, rather it helps you deal with renal failure. It is life-saving and without it, the kidneys will no longer function.

There are two types of dialysis treatments that you can choose from:

Hemodialysis   This type uses a machine to remove waste from the blood and sends it back to your body. It can be done at home or at a dialysis center.
Peritoneal Dialysis   This type uses the lining of your belly called the Peritoneum to do the work of your kidneys. A catheter and dialysis solution is used to carry out the function.
There are benefits and complications for each type of dialysis. The treatment decision will largely depend on the patient s illness and their past medical history. Discuss with your doctor to decide the best option for you.

2. Kidney Transplant: Kidney transplants can provide a better quality of life than dialysis and can be seen as a potential cure for kidney failure. A healthy kidney from a live donor or deceased donor is surgically placed in your body as a replacement to the failed kidneys. Although this may be a better option for you, it has certain shortcomings. There is an element of rejection and you may have to wait for a long time to get a donor. Extensive testing and anti-rejection medications are prescribed with this treatment.

3. Palliative Care: Rather than cure, it is the care that people with serious illness need. With so much to deal with, the patients have an array of tough questions and challenges to deal with. Patients need to take into account all medical options and care options based on their condition and severity of the renal failure.

Making the right treatment choice is difficult and that too when you are ill. It is normal to be fearful and worried about the risks involved. Get support from your family and doctor to help you make the right treatment choice. It may also be helpful to visit a dialysis or transplant center to talks to others who have been through these treatments.

The ideal diet after a kidney transplant

A kidney transplant is a surgical procedure where your kidneys are cleansed and rebuild using the kidneys of a deceased person, in order to flush out the excessive waste fluids from the kidneys. It is of paramount importance and your dietary patterns and lifestyle should be altered after you go through a kidney transplant. Your dietician will help you out by preparing your diet chart to clearly list out the foods that you should consume and those which you should avoid after the surgery. The diet chart that would be prepared for you would be highly subjective and it would totally depend  on your lifestyle, medical history, family health records, genetically transmitted conditions and such others. Apart from improving the condition of your kidney and assisting your transplant, the diet chart will also help you to lose weight, boost your metabolism and enhance your immune system. Some of the most common recommendations that your dietician may give you are as follows:

-Eating at least 5 full servings of fresh fruits and vegetables each day as both are an important part of a healthy diet for a person who has just undergone a kidney transplant. The vegetables should mostly be eaten after cooking/boiling as per the suggestions of your dietician.
-Having enough of fiber rich foods in your daily diet is essential as it speeds up the process of digestion and prevents constipation by promoting frequent and easy bowel movements.
-If you are a non-vegetarian, then you should be going for lean meat alternatives which are low on fat and high on nutritional value. -Examples of such meat are fishes and poultry. Additionally, you should also avoid all kinds of red meat as it is high on fat.
-Consume low-fat milk and dairy products as they help to prevent the fat accumulation inside the body and also maintain an acceptable level of calcium and phosphorus inside your body.
-Maintain a low level of iodized salt in your meals, as it helps to keep your blood pressure under control.
Over the counter health supplements like vitamins and proteins can also be taken, if recommended by your dietician.

The Ideal Diet after a Kidney Transplant

Acute kidney failure is the kidney's inability to filter waste from the blood. As soon as the kidney loses the filtering ability, a humungous amount of body waste gets accumulated in the kidney and the chemical makeup of the body goes out of balance. Kidney or renal failure can progress tremendously from hours to days. This is a condition that is mostly witnessed in critical patients who are already hospitalized. This condition can prove to be fatal but can be reversed with treatment and medication. Here is a list of things one should do whilst suffer from kidney failure:

Lifestyle and dietary adjustments
During the phase of recovery, the medical team might assist a patient to go a special diet and limit the activity of the kidney so that they get the required time to heal. A nephrologist often routes this cases to a dietician or carefully analyses the present diet to lock up on the diet required for a speedy recovery:
Lower amount of potassium in food: Food with low potassium content is often recommended by the doctor. It ensures that kidney does not stress itself. Foods to avoid include spinach, bananas, oranges, tomato and potato. Some of the foods that need to be included in the diet are cabbage, strawberries, apples and grapes. Furthermore, food must be consumed in small quantities but in multiple servings.
Limit the amount of phosphorus in food: Phosphorus is found in abundant quantities in food items such as peanut butter, milk, dried beans, cheese and nuts. Along with skin itchiness, phosphorus can weaken the bone as well. A dietitian might share special instructions on how to cut down the amount of phosphorus and the substitute food to counter the effect of the above-mentioned ones.
Avoid salty products: It is extremely necessary to cut down food items that contain an excess amount of salt in it. Food products such as the canned soup, frozen dinner, and fast food are the major culprits in worsening the condition. Processed meats and cheese are equally bad.

Preventive measures to avoid kidney failure:

OTC pain medications: It is necessary to check the label of over the counter pain medications. Consumption of too many OTC medications can result in kidney failure. A pre-existing kidney condition can further aggravate this condition.
A healthy lifestyle: A sensible lifestyle with simple diet can do wonders for a kidney to be healthy in the long-term. Some of the other things to keep in mind include doing regular exercise, refrain from alcohol or drug abuse and remain active throughout the day.
Consult a doctor: Even a hint of a kidney problem should be discussed with a doctor to ensure that even the smallest of problems can be addressed at the earliest.
