Causes and symptoms of acute tubular necrosis

Damage or destruction to tube-like structures known as tubules in the kidneys can bring about the development of acute tubular necrosis (ATN) and subsequently, acute kidney failure.

What causes acute tubular necrosis (ATN)?

A lack of supply of oxygen to the cells in the kidney is the most common cause of this condition. The reason as to why oxygen may not reach the cells and tissues of this organ could be restriction or blockage of the pathways. When this happens, the kidneys get damaged. Dehydration is the most important cause of ATN which may be because of loose motions, vomitings, heat stroke etc.

Health conditions such as diabetes, heart attack, and stroke can bring about a decrease in blood flow to the organs resulting in ATN and death of cells. Similarly, the presence of toxic substances in the blood can also lead to tubules damage and change the way the cells function in the tubules.

Other causes that may lead you to develop ATN may be medications, radiology dyes, anesthetics and chemicals that cause your body to react adversely.

In addition to these causes, a number of factors can put you at risk of ATN and there are:

- An injury to the body, more specifically your kidneys can cause clotting of the blood vessels
- An adverse response to blood transfusion
- Instances of septic shock can slow down blood flow to the organs
- A major surgery that can interrupt blood supply to the organs

What are the symptoms of the condition?

The symptoms associated with the condition can vary depending on the severity of the problem.

You may experience:

- Troubles in waking up
- Drowsy feeling even during daytime
- Feelings of lethargy
- Feelings of excessive thirstiness
- Problems with urination
- Fluid retention problems
- Instances of confusion
- Feelings of nausea



Can Acute Tubular Necrosis Cause 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?

One single kidney in place of two is a scenario which is often termed as solitary kidney.

Who has a solitary kidney?

Their body functions normally and are generally not unhealthy. This is also known as renal agenesis.
In some cases, people are born with two kidneys with just one of them healthy and fully functional. The other one does not function fully or partially. This condition is known as kidney dysplasia.
A person who had to undergo a kidney removal surgery (nephrectomy); such a surgery is conducted when a person has an infected kidney or diseased, malfunctioning/cancerous growths on the kidney.
A person who has donated a kidney to someone who required kidney transplantation.
What potential health risks does a person with a solitary kidney have?

Normally, a person born with a single kidney does not have any such potential health risks. They are generally healthy and lead normal lives.
Later in life, there may or may not be slight loss or degradation in the functioning of the kidney.
The life span of a person with a single kidney is normal. There is no apparent effect on the mortality rates.
What kind of special diet must a person with a single kidney follow?

There is no need of any such special diet for a person with a single kidney.
Normal healthy balanced diet with all the essential nutrients should suffice.
You must be careful about your animal protein intake and calcium supplements.
Drink sufficient quantity of water to remain hydrated all day and prevent the urine from turning acidic.
Controlled consumption of alcohol and caffeine is a must. It is also important to reduce the consumption of aerated drinks.
Exercises and Physical activities for a person with a single kidney:

A person with a solitary kidney can function like any other normal individual.
You may also participate in sports. However, you must take enough precaution to prevent injuries to your kidney. Proper padding and protection around your lower abdominal region and back is of utmost necessity.
You can hit the gym, run a marathon and nothing is impossible for you.

Living With Solitary Kidney - Things You Need to Know!

A lot of bad things can and do happen when the kidneys fail.  The kidneys are vital for proper bodily functioning because they filter liquid and solid waste products out of the blood and allow vital chemicals (which the body needs for functioning) to flow into the body through the bloodstream.  People can become very sick when the kidneys either fail to perform these functions or fail to perform them properly.  Many people will get chronic kidney disease, therefore, they need to know what the causes and symptoms are in order to treat, and even prevent these diseases from occurring.

People who suddenly experience the following symptoms should see a nephrologist as soon as possible for a medical examination:  blood or protein in the urine, kidney stones, acute kidney injury, kidney infections, and/or pain, and Hepatitis C and kidney disease.  

Blood in the urine can be a sign of kidney problems which can lead to kidney disease.  Additionally, people who urinate frothy or bubbly urine, or have swelling in the hands, face, and feet should see a doctor because this is a sign of protein in the urine.  Protein in the urine can be detected by a urine test.  Kidney stones can be very painful and are problematic.  They are caused by mineral buildup in the kidneys.  Men and white people tend to get kidney stones more, and they can cause blood in the urine, painful urination, sharp lower abdominal or back pain, and nausea and vomiting.

Acute kidney injury occurs when the kidneys stop functioning altogether in a short period of time.  Because this disease can be deadly, those with this disease should get immediate medical help.  Usually, the very sick patients in hospitals get this disease, but it can also be caused by certain medicines, injury, or infections.  This type of kidney disease is easily reversible.  

Symptoms include

Not passing enough urine when urinating
Leg, ankle, or feet swelling
Fatigue
Breathing problems
Confusion
Nausea, and chest pressure or pain. 
Kidney infections tend to be caused by bacteria that have spread from the urinary tract.  Women, because of their anatomy, tend to get kidney infections more than men. 

Symptoms include:

Fever
Vomiting
Back, side or groin pain
Chills
Nausea
Frequent urination
Frequent urges to urinate
Painful or burning urination
Pus or blood in the urine
Cloudy or foul-smelling urine
Kidney pain in the lower back or sides can signify more serious kidney problems.  They can be caused by urinary tract infections, polycystic kidney disease, kidney infections, blood clots, and/or bleeding in the kidneys.  
Hepatitis C is a disease that attacks the liver and can cause kidney disease.  

Symptoms include

Loss of appetite
Nausea
Fever
Fatigue
Vomiting
Dark colored urine
Grey colored stool
Joint pain
Yellow skin and eyes
While kidney diseases are at best unpleasant, and at worst, life-threatening, they can be avoided by drinking lots of water, eating a healthy low salt diet, and watching for any changes in health and urine over time.



What Happens When Kidneys Fail & Signs That Indicate It

Nephropathy is also known as renal disease. It is any type of damage or disease relating to the kidneys. Though not everyone with diabetes has nephropathy, however, diabetic nephropathy can cause kidney failure.

How does diabetes affect the kidney?
Kidneys are responsible for taking waste out from your blood. They have a lot of tiny blood vessels to do this. High blood sugar may kill such blood vessels. Once these blood vessels are destroyed, the kidneys may not function as well or it may even lead to kidney failure.

What increases your risk of getting diabetic nephropathy?
There are several factors which increase your risk of getting diabetic nephropathy including: \
1. High blood pressure
2. High cholesterol
3. Smoking
4. Being native american, african american or of hispanic origin, for whom risk factors have proved to be magnified
5. If you have family history of diabetic nephropathy

Symptoms and diagnosis:
There are very few noticeable symptoms, which appear when you have diabetic nephropathy, except swelling in your arms and legs. The diagnosis is done by checking for a type of protein in your urine known as albumin, which is not supposed to be there. Getting the diagnosis done early is crucial.

Preventive measures
You can prevent kidney damage by doing the following:
1. Keeping your blood sugar levels under control - keep hba1c &lt; 6-7%
2. Keeping your blood pressure under control in the range of 130/80
3. Eating healthy food
4. Exercising regularly
5. Not eating too much protein
6. Not eating too much salt
7. Reducing smoke or excessive tobacco usage

Medicines for treatment
If you do get diabetic nephropathy, here are some medicines, which can help cure it
1. Ace inhibitors which are also called angiotensin-converting enzyme inhibitors
2. Angiotensin ii receptor blockers (arbs)

Possible complications
1. Blood pressure may rise
2. Triglyceride levels and cholesterol levels may rise.

All About Diabetic Nephropathy

Those two, small bean-shaped organs are indeed essential for a perfectly healthy life. To check if a person is dead or living, medical practitioners need to confirm response from three organs of the human body heart, brain and kidneys. Kidneys absorb impurities from the blood, thus, purifying it and lead to the production of urine. Urine is necessary to rid your system of body wastes. Kidneys play a key role in maintaining hormone balance. The presence of any factor that could impede free functioning of this organ should be diagnosed, treated and eliminated at the earliest possible. Kidney diseases and subsequent kidney failure see no age bar. It affects both young and old people. In case of younger folks, the symptoms take years to surface and thus the chances of a fatal outcome are even higher.

Causes of kidney failure at a tender age:

    Chain smoking is a trigger: Smokers suffer from a higher risk of kidney failure. Smoking is a bad habit that has engulfed almost ninety percent of young adults. Irrespective of awareness programs and warning messages, there are millions who smoke nonchalantly. Smoking is known to impair kidney function which again can have frightening implications.
    High blood pressure levels must be controlled: Since stress is a common phenomenon among most individuals high blood pressure is also prevalent among a majority of these individuals. Younger people suffer from high blood pressure due to workplace politics and familial tensions. High blood pressure should not be taken lightly. Exercising and regular medications should be opted for in order to counter the threat of kidney failure at a young age.
    If you are obese, you are stepping closer to the threat: If not optimal; being close to the optimal body weight is very necessary to keep health disorders in check. If you are obese, you are not safe; one must make efforts to lose weight or else face the alarming situation when his or her kidneys fail to function properly.
    Consumption of junk food can cause complications: Junk food is fatty. One must keep away from high-protein and high-fat diet. Food items rich in protein and fats can push you towards chronic kidney diseases.
    Genetics may discern the health of your kidneys: The incidence of kidney failure in your family history can make you prone to a similar condition. Extra care should be taken to avoid any such possibility. Regular health check-ups should be undertaken.
