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?

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!

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. 

Acute Kidney Failure - What Should You Do In Such A Case?

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.

When do kidneys need dialysis?

Kidneys are a pair of organs that are located on either side of the spine, each about a size of a fist. The kidneys help in purifying blood by removing toxins, waste materials and excess fluids from the human body. Disorders and dysfunctions of the kidney can lead to severe and often fatal consequences. When the kidneys stop functioning as they are supposed to, dialysis is performed to resume normal functioning in the body.

Dialysis is a type of treatment, which filters and purifies the blood with the aid of a machine. It is an artificial way of purifying blood. There are two types of dialysis, namely hemodialysis and peritoneal dialysis. Hemodialysis, the most common form of dialysis, which involves using a manmade kidney called a hemodialyzer, which removes toxins and waste materials from blood.

Peritoneal Dialysis, on the other hand, is a type of treatment which involves implanting a catheter in the stomach. During the procedure, a fluid called dialysate flows into the abdomen that absorbs all the waste material, which is consequently drained out of the body.

You may need a dialysis if:

- Your kidneys are dysfunctional
- When waste materials and toxins start to accumulate in the body
- In an event of an injury or accident to the kidney such as internal lacerations (wound caused by the tearing of a tissue)
- If the creatinine (a type of a chemical waste product) level falls to 10-12 cc/minute
- In an event where the kidneys aren't able to work properly leading to accumulation of toxins, irregular amounts of chemicals in the body and other dysfunctions

Weakening of the abdominal muscles and weight gain are some of the risks involved in dialysis. Dialysis is a temporary treatment and serves to function till the time the actual kidneys get repaired. In chronic cases of kidney disease, kidney transplant may perhaps be the last resort.



When Do Kidneys Need Dialysis?

The most common dietary problem that every vegetarian comes across is protein deficiency. It was a widely acknowledged fact that animal products are the best protein sources. However, it is no longer so, and vegetarians everywhere can now rejoice!

Here are the 13 best sources of protein for vegetarians:

Green peas: Green peas are legumes, which are a very good protein source. They contain 7.9 grams of protein per serving.

Quinoa: Grains usually contain very little protein, but quinoa is unique. It contains 8 grams of protein per serving, and contains all nine important amino acids that your body needs for repair and growth.

Nuts and nut butter: Nuts are a good source of proteins and healthy fats. However, eat them with caution, as they do contain 160 calories per serving. Butter made from nuts like peanut butter and almond butter is also a good source of protein.

Beans: Beans are available in a variety of colours and shapes, but all of them have one thing in common that is the high level of protein.

Chickpeas: Chickpeas are also from the legume family, so they also contain high amounts of protein; 7.3 grams of protein in only half of a serving.

Tofu and tempeh: Tempeh and tofu are both soy products and they have the highest amount of vegetarian proteins, about 15-20 grams per serving.

Edamame or soybean: Edamame or soybean is excellent for snacking. They contain 8.4 grams of protein in just half a cup.

Leafy greens: Vegetables usually do not contain much protein, but eating green vegetables will significantly add to your protein consumption. For example, you can eat one cup of cooked broccoli as that contains 8.1 grams of protein.

Hemp: Blend hemp seeds in smoothies or baked goods to get your daily dose of protein. Hemp contains 10 grams of protein per tablespoon.

Chia seeds: Chia seeds contain 4.7 grams of protein per two tablespoons, making them excellent sources of protein.

Seitan: This is a meat substitute made from wheat gluten and it contains 36 grams of protein per serving (about half a cup).

Non-dairy milk: Milk made from soy (best non-dairy protein source), almond, rice and hemp are good dairy substitutes.

Unsweetened cocoa powder: This will surprise you, but bitter cocoa contains nearly 1 gram of protein per serving (1 tablespoon)! 
All the above-mentioned food items are the best source of proteins for vegetarians. So, enjoy them with no worry.
