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?

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

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!

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!

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

Often, early stages of kidney diseases do not come with specific signs and symptoms and most people will remain unaware of their condition. However, certain symptoms may be perceived that may indicate that a person is suffering from early stages of kidney failure. When you are diagnosed with kidney failure (also known as renal failure) in the initial stages, certain measures can be taken to retard the progression of the renal disease. This can also help reverse the condition and improve the quality of life of the patient. On the basis of a typical cause, the symptoms of kidney failure are grouped into specific categories that are given below. If you notice any of the specified renal failure symptoms, it is recommended to immediately fix up an appointment with your doctor and get your diagnostic tests done. 

Symptoms of Renal Failure from the accumulation of waste products in the body: 

Metallic taste in mouth 
Nausea and vomiting 
Facing difficulty in concentrating 
Loss of appetite 
Aversion towards meat (protein aversion) 
Itching or pruritus 
Symptoms of Renal Failure from the accumulation of fluid in the body: 

Dyspnoea or shortness of breath (this happens due to the accumulation of fluid in the lungs).
Swelling is seen in the feet, hands or face. 
Symptoms of Kidney Failure from damage to the kidneys: 

The amount of urine production changes, though it is not a reliable sign Haematuria or blood in the urine (usually in microscopic quantity). 
Frothiness or foam in the urine (usually happens when protein is present in the urine). 
Symptoms of Kidney Failure due to decreased blood production (anemia): 

Dyspnoea or shortness of breath. 
Fatigue Weakness. 
Confusion If you happen to feel cold all the time. 
The following diagnostic tests will be performed by your doctor in order to determine whether the symptoms are the manifestation of a kidney failure or not: 

Urine analysis - In this test, a sample of your urine is tested to find traces of blood, white blood cells or proteins which may indicate a problem in kidney function. 
Blood Tests - This includes tests for BUN and creatinine in the blood which are usually removed from the blood if the kidneys function properly. 
Actions must be taken when you show signs and symptoms of kidney failure: 

It is common that the symptoms of early renal failure are not always prominent, but if any of the above symptoms are witnessed, it is recommended to met a physician to determine whether they are caused by a kidney disease. You can pen-down the symptoms that you feel are related and bring it to the doctor when you fix up the next appointment. It is essential to know about your disease at the earliest as it will give you time and the ease of taking measures to retard the damage process and will decrease or delay the probability of undergoing dialysis or kidney transplant.
