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?

The kidneys make urine, which is a fluid through which wastes from the body including urea are eliminated from the body. There are two kidneys on the right and left side, which make urine, and pass it down to the bladder through tubes known as ureter. The bladder acts as a reservoir of the urine that is formed in the kidneys. It is stored temporarily there before being excreted out of the body through the urethra. The urinary bladder is a highly muscular organ and has a rich connective tissue. 

Interstitial cystitis (IC) or painful bladder syndrome (PBS) is a very common condition, which affects females more than males. While the exact etiology is not known, it could be age-related and also lifestyle related. People who are used to controlling the urge to pass urine are highly likely to develop this condition. The simple logic is that there is additional pressure on the bladder from the urine that is contained for longer period of time. As such, the muscular wall stretches and begins to feel stressed.

When this habit continues over a period of time, the bladder wall may become irritated or inflamed or even scarred in severe cases. There is no role of bacteria in this condition, and antibiotics are of no help in managing this condition (though the name cystitis usually indicates infection).

The following symptoms are seen as a result of this constant irritation and inflammation.

One may suffer from pain and pressure in the bladder as it continues to collect more and more urine.
This pressure in the bladder also puts pressure on the surrounding tissues in the abdomen including the pelvis, urethra, abdominal organs, uterus, etc.
Women may experience pain in the vaginal tract including vulva and behind the vagina.
Men may experience pain in the area of the scrotum, testicles, prostate, and penis.
There is an increased urge to urinate, which may be as much as 9 to 10 times a day. As the condition progresses, there could be more visits, as many as 40 to 50 visits a day.
This tendency and urge to urinate increases during nighttime.
For women, this urge to urinate and other symptoms including pain are worse during menstruation.
There could be pain during intercourse for both men and women.
There could be pain even otherwise, which can range from a mild dull ache to a piercing pain.
At a structural level, this constant pressure leads to pinpoint bleeding (glomerulations) and sometimes even ulcers in the bladder wall.
There is no definitive treatment for IC or PBS. However, bladder distention and instillation are proven methods of increasing bladder capacity, which therefore helps in relieving symptoms.

Painful Bladder Syndrome - Know The Signs!

Bladder cancer is characterized by irregular growth of abnormal tissue (tumor) on the lining of the bladder. This type of cancer may spread to the surrounding tissues or other body parts as well.

What are the causes?

Bladder cancer can be caused by environment-related factors and smoking. In fact, smoking tobacco is one of the major causes of bladder cancer around the world. The chemicals present in tobacco can irritate the bladder lining which ultimately leads to bladder cancer. It may also be caused by continuous exposure to chemicals such as dyes or leather dust and radiation. These chemicals tend to cause unusual changes in the cells of the bladder lining and causes cancer in the bladder.

It can also be caused by modifications in the dna in the cells of the bladder which may impair the functioning of the cells in the body. This can cause mutations in the bladder resulting in cancer.

What are the symptoms?

1. Presence of blood in the urine, often painless

2. Feeling of pain while passing urine

3. Back pain

4. Excessive urination

5. Infections in the urinary tract

6. Lower leg swelling

7. Pain in the bones, especially in the pelvic area

8. Weight loss

Treatment options

Treatments for bladder cancer depend on the stage of the cancer. The various treatment choices are:

Surgery - In some cases, these cancers are surgically removed by a surgeon. A type of surgery used is transurethral resection of bladder tumor (turbt) where the cancer cells are destroyed with laser by passing a thin fiber into the bladder.

Chemotherapy - In this method, medications are used to target and destroy cancer cells.

Radiation therapy - Radiation therapy uses rays such as x-ray or uv rays to destroy cancer cells in the body

Immunotherapy - This treatment boosts the immune system of the body so that it attacks the cancerous cells in the bladder.

Causes And Symptoms of Bladder Cancer

What is diabetic kidney disease?
Diabetic nephropathy, also known as Diabetic Kidney Disease is a type of complication that occurs in people who are a victim to diabetes. That does not mean every individual with diabetes will have this disease, but if the necessary precautions are not taken, then it can lead to this disease. Diabetic Kidney Disease is characterised by excessive amounts of albumin as well as protein in the urine. In diabetics, certain chemicals in the kidneys shoot up and hamper the function of the glomeruli.

The glomeruli are the main units of kidneys that are responsible for the filtration. Diabetic kidney diseases result in the leakage of essential products like albumin and protein into the urine. When this happens, the protein levels in the blood reduce. If proper precautions are not taken and treatment is not done, then the disease may worsen and the condition will progress to  end-stage renal failure .

How to avoid diabetic kidney disease?
The best way to treat diabetic kidney disease is to prevent it in the first place. Foremost, you should prevent the risk factors in order to avoid coming down with Diabetic Nephropathy. The risk factors include high blood pressure, high levels of blood sugar, dyslipidemia and smoking. Avoid excess of following 5S Sugar, Salt, smoke, stress and sedentary life.

Intensive control over blood sugar
According to certain clinical trials, maintaining and keeping a good control over your blood sugar levels drastically reduces the risk of developing diabetic kidney disease. If you are diabetic, make it a point to get your regular checkups and maintain your diet to prevent the levels of sugar in your blood to shoot up. Other things that you must keep in your mind are to take proper medication that has been prescribed to you. You must adhere to your treatment plans and follow the guidelines that have been given to you.

Intensive control over blood pressure
Hypertension is common in patients who are diabetic. Hypertension alone can result in end-organ damage due to excess pressure build up in the blood vessels. Hypertension associated with hyperglycaemia (diabetes) is a ticking bomb for your kidneys. Hence it is advised to keep your blood pressure under control as well to prevent diabetic kidney disease.

Diabetic nephropathy is not something that happens to every individual with diabetes, so if you follow the above simple tips, the chances of the same reduce, and thus the quality of your life goes up. Many diabetics will get kidney failure due to causes other than diabetes and that may be treatable. Hence early consult with nephrologist is a must.

Diabetic Kidney Disease - How It Can Be Prevented?

What is Chronic Kidney Disease?

Chronic Kidney Disease (also known as Chronic Renal Failure) is the progressive loss of kidney function occurring over a span of several months to several years and is characterised by the replacement of kidney architecture with interstitial fibrosis.

Chronic kidney disease is classified into five stages on the basis or proteinuria (presence of protein in large amounts in the urine) or Glomerular Filtration Rate (GFR) - 1 being the mildest with no distinct symptoms and 5 being end stage renal failure.

Causes and Risk Factors of Chronic Kidney Disease-

The various reasons (called risk factors) that can increase chances of Chronic Kidney Diseases are:

Diabetes mellitus, hyperlipidemia (excess fat proteins in the blood)
Hypertension

Family history heritable renal disease

Older age, smoking

Autoimmune disease

Past episodes of acute renal disease

The direct causes of Chronic Kidney Diseases are-

Diabetic nephropathy (leading cause)

Hypertensive nephropathy

Glomerulonephritis (swelling of the glomerulus in the kidneys)

Reno-vascular disease (ischemic nephropathy)

Polycystic kidney disease

HIV-associated nephropathy

Transplant allograft failure

Exposure to drugs and toxins

Diet that you must maintain in Chronic Kidney Disease-

It is essential to make dietary as well as lifestyle amends once you are diagnosed with CKD. The main purpose of this diet is to maintain the levels of carbohydrates, fluids and minerals. This is done to prevent the buildup of waste products in the body as the kidneys are unable to fulfil its function properly.

It is recommended to refer a dietician who can make you a diet chart that helps you adhere to your diet.

Here is a list of food items that you may avoid or may consume if you are suffering from Chronic Kidney Disease:

Carbohydrates : Carbohydrates are a good source of energy. If the intake of protein has been restricted, then it is recommended to replace that with carbohydrates as a source of energy. Fruits, vegetables, grains and bread can be consumed as they are rich source of fibres, minerals and various types of vitamins. You can indulge in some hard candies or sweets as well.

Fats: Fats can provide a good amount of calories as well. Ensure that you only stick to healthy fats such as the monounsaturated and polyunsaturated fats that are good for your cardiac health. 

Reduce your phosphorus intake: A diet with no more than 800 mg of phosphorus can help reduce the risk of too much phosphorus building up in your blood.  Limit intake of foods with high levels of phosphate or phosphate additives such as organ meats, whole grain breads, processed foods, cola beverages, cheese, dried beans, liver, peanut butter, dairy products and chocolate. Many beverages and processed foods have these additives. Other high-phosphorus foods to limit include: 

Cheese
Chocolate
Ice cream
Legumes
Milk
Nuts
Seeds
Yogurt
Monitor your potassium levels: Usually, potassium is not restricted in stage 3 CKD unless lab tests show potassium is too high. Your doctor may make medication changes or prescribe a low-potassium diet. Reduce an elevated potassium level by limiting some high-potassium foods and potassium chloride (found in salt substitute and many low-sodium processed foods), such as avocado, bananas, cantaloupe, honeydew, legumes, milk, nuts, potatoes, seeds, tomato products and yogurt. Some high-potassium foods to limit or avoid include: 
Avocado
Bananas
Cantaloupe and honeydew melon
Dried fruit
Legumes
Milk
Nuts and seeds
Oranges and orange juice
Potatoes
Pumpkin and winter squash
Tomato products (juices, sauces, paste)
Yogurt
Proteins: Usually, before undergoing dialysis, it is recommended to adhere to a low-protein intake diet. However when you are undergoing dialysis, it is necessary to consume a certain amount of protein. This detailed information can be obtained from your dietician.
Fluids: In the early stages of CKD, your fluid intake is not monitored. But as the disease progresses, you need to check your intake of fluids as too much fluids may accumulate in your body and create pressure on your kidneys.

Sodium Or Salt Intake: Keeping a check on your salt intake reduces the risks of high blood pressure. Also, having food low on salt can reduce your thirst and prevent fluid retention in your body.

Diet In Chronic Kidney Disease

Diabetes is a lifestyle disease that is very prevalent in the current generation. According to a report by the World Health Organisation (WHO), the number of people with diabetes has risen from 108 million in 1980 to 422 million in 2014. The global prevalence of diabetes among adults over 18 years of age has risen from 4.7% to 8.5% from 1980 to 2014. Diabetes should not be taken lightly as it can affect other body organs besides the pancreas, such as the kidneys. Diabetic nephropathy refers to damage to your kidneys caused by diabetes, and may also lead to kidney failure in various cases.

Causes of diabetic nephropathy
Not everyone who suffers from diabetes will suffer from diabetic nephropathy. The main function of the kidneys is to filter waste from your blood. However, this is not always the case. Due to high a concentration of blood sugar caused by diabetes, several blood vessels in the kidney are destroyed, thereby, preventing the kidneys from carrying out its job. Over time, the kidneys may stop working altogether, resulting in kidney failure. If you are diabetic, the probability of you suffering from diabetic nephropathy will increase if you smoke or have high blood pressure or high cholesterol.

Catching it early
Today, diabetic nephropathy is the leading cause of chronic kidney disease in the US and other western countries. Since the symptoms of this condition aren t visible in its early stages, you need to undergo urine tests on a regular basis. If detected early, the effects of diabetic nephropathy can be reversed. Common symptoms of this disease include the following:

Swelling in legs and feet
Detection of albumin in urine
Decline in glomerular filtration rate (GFR)
Elevated arterial blood pressure
What are the treatment options?
Medication to lower the blood pressure is the most commonly prescribed form of treatment suggested by doctors to prevent or slow the damage to your kidneys. There are other lifestyle changes that you may have to undertake in order to keep a check on the condition:

Limit sugar intake and keep blood sugar levels within the target range
Exercise regularly and work towards keeping your heart healthy
Limit protein intake, as it could put extra pressure on your kidneys
Limit salt intake to control blood pressure
Quit smoking and drinking
Diabetes is an unfortunate condition to have to live with. But don t let it bog you down! With these simple lifestyle changes and taking care of your general well-being, you can beat the disease and emerge a winner!
