Types Of Kidney Diseases

Types Of Kidney Diseases
Kidneys are very important to us. Presence of kidney disease can be very devastating to a person especially if there is no active functioning of the kidneys. A kidney dialysis or transplant to replace the diseased kidney might be required in worst case scenarios.



There are however several types of disease of the kidney that are classified as worse than the others. There are kidney diseases which can be "acute" implying that it is on first onset, and "dronic" implying that there is slow decline in kidney function. Both of these kidney diseases might arise due to autoimmune disorders, toxins, medications and as well infections. The worsening of the kidney functions might also be brought about by disease such as diabetes and blood pressure, although it can occur gradually.



When kidneys leak out some certain fluids or substances, it brings in another classification. Hematuria or blood urine is one of these diseases. These can be caused by sickened kidneys leaking out blood cells from the capillaries in the kidneys.



Protenuira is another fairly common kidney disease and usually comes about when protein and mostly albumin leaks out from the body. It can sometimes become so developed that there are instances where there is barely enough proteins in the body. Basically, without protein, fluid will leak all over the body (a condition referred to as "nephritic syndrome". This is always not good as we need the protein to keep the blood flowing in their vessels.



Kidney stones presence is another kidney disease where a patient excretes too much calcium oxalate into the urine and fails to drink enough water. Kidney stones might as well be caused by uric acid. Precipitation of the uric acid into stones makes it hard for them to fit in the uterus. Usually extreme pain is experienced and might result into infections as well.



Hypertension or the medications treating it might result into kidney disease. There are cases where one or both arteries leading to the kidneys are blocked forcing the kidney to release vasopressin which makes the blood pressure to rise dramatically. There are however specific blood pressure medication that can address these problems or in some cases surgery is administered to the blockage.



Chronic pyelonephritis occurs when infection gets deeper in the kidneys hence causing a lot of pain and kidney inflammation. It can as well result from hematuria.



There is however one primary disease that is cancerous and the cancer may further cause a lot of pain or bleeding in the kidney areas. This is always referred to as renal cell carcinoma which is usually treated by the replacement of the sick kidney(s)

Kidney Diseases In Children

Kidney Diseases In Children
Chronic kidney illness of any kind in children is the most unwelcome news for any parent in the world. They subject children to lonely childhoods blighted with frequent illnesses and regular hospital visitations. A child who is supposed to grow happily is instead left attending hospital operations most of the time. The parents are not any better off as they are angry and depressed not to mention the high costs that they will have to incur in meeting the hospital bills.



For this reason and many others, it is of paramount importance that a parent learns to cope with these kidney diseases so that they can instill hope and courage in their children. It is important that they teach their children that these are normal diseases that can affect anyone so that their children may find the strength to grow up. They should make their children know that this is not the end of life and instead show them how to treat the disease including what drugs to take at when the symptoms are seen.



Kidney ailments in children may be acute or chronic.



Below are some of the kidney problems that children are likely to suffer from:



Hemolytic uremic syndrome



The above affects children mostly under the age of ten years.



This is a rare disease and one which has high chances of causing kidney failure. When a child eats foods that are contaminated with bacteria, they may get an infection of the digestive system. This causes diarrhea and vomiting. The child becomes restless and pale after the symptoms have subsided. The toxic substances produced by these bacteria may damage the kidney, leading to acute kidney failure. Children with this condition often need blood transfusion.



Nephrotic syndrome



A child with this condition tends to urinate less often, and the water left in the body causes swelling in the eyes, legs and the stomach. The small amount of urine that the body makes is concentrated and contains high levels of proteins. A healthy kidney will keep the protein in the blood but a defective one leaks the protein in the urine.



This condition is normally treated with prednisone to prevent the leakage of protein into the urine. The child is supposed to take small doses of prednisone and eventually come back to normalcy without permanent damage to their kidneys.



Detection of these diseases will help in mitigating their effects.






Useful Information On Kidney Diseases

Useful Information On Kidney Diseases
End-stage renal disease occurs when the kidneys are chronically
unable to function sufficiently on their own, so that dialysis or
kidney transplantation becomes necessary to maintain life.


Nutrition may affect persons who have, or are at risk for developing
renal disease. The intake of certain nutrients may influence the rate
of progression of renal failure in persons with underlying renal
disease. High-protein diets can strain the kidneys to the point of
failure. This is substantiated by the findings that the prevalence of
stone disease in vegetarians is only about 50% of that in the general
population. [Robertson, et al] A high intake of animal
protein increases the urinary excretion of calcium and oxalate and the
accompanying increase in purine intake increases uric acid excretion.


Functioning kidneys regulate the composition and volume of body
fluids within very narrow limits. They do so by balancing intake and
excretion of body fluids and waste products derived from metabolic
processes. If the kidneys fail to maintain homeostasis, a wide range of potentially lethal metabolic disorders can develop throughout the body.


The kidneys remove unwanted salts, waste products, and other
chemicals from the plasma along with the water in which they are
dissolved. When the concentration of certain salts in urine exceeds the
limits of solubility, the salts crystallize and form stones within the
kidneys. Treatment of these conditions by diet or drugs is aimed at
reducing the concentration of stone-forming substances in the urine.
The principal means to this end is to increase urine production by
drinking water throughout the day unless on a low-fluid regimen.



The substances found most frequently in kidney stones include
calcium, oxalate, phosphate, uric acid, and cystine. Usually these
substances are derived from foods, but oxalate and uric acid can also
be synthesized endogenously.


Dietary measures to reduce oxalate include restriction of
oxalate-rich foods, such as beetroot, rhubarb, spinach, chocolate, and
tea, and restriction of excessive intake of ascorbic acid, which is
metabolized to oxalate. Uric acid stones are treated with diets low in
purine-rich foods, such as organ meats, fish, shellfish, and legumes.
Persons with cystine-containing stones respond successfully to low
protein diets. Calcium phosphate stones are treated successfully with
high-phosphate diets that increase urinary excretion of pyrophosphate,
an inhibitor of calcium crystallization.


Chronic renal failure is the consequence of longstanding and
progressive renal damage and is usually irreversible. Chronicrenal
failure causes extensive disorders in appetite as well as in the body's
absorption, excretion, and metabolism of many nutrients. Consequently,
nutritional therapy is essential in managing this condition.


The chronic renal failure patient is also likely to accumulate
certain potentially toxic chemicals that normally are ingested in small
amounts and excreted in the urine. Aluminum is such a toxin; it can
cause severe bone disease, dementia, muscle weakness, and anaemia in
persons with kidney failure.


Treatment of renal disease may demand severe dietary restrictions or
induce nutrient losses. Dietary management of this condition,
therefore, must provide protein, energy, and other essential nutrients
in amounts adequate to avoid deficiencies but sufficiently restricted
to avoid stressing the diminished excretory capacity of the diseased
kidney.


The goals of nutritional therapy for both acute and chronic renal
failure are to maintain optimal nutritional status, to minimize the
toxic effects of excess urea in the blood, to prevent loss of lean body
mass, to promote patient well-being, to retard the progression of renal
failure, and to postpone initiation of dialysis.


These goals are accomplished with the following methods:-





  • Restricting Fluid Intake: Energy,
    protein, and other essential nutrients are provided in as small a fluid
    volume as is possible to maintain water balance.


  • Restricting Protein:
    Nitrogen balance must be maintained without any unnecessary
    accumulation of urea or other toxic nitrogenous waste products. To
    enhance incorporation of amino acids into body protein and to reduce
    protein breakdown in more severely ill persons, dietary protein or
    supplements of high biologic value (containing a high proportion of
    essential amino acids) are often recommended.



  • Increasing Energy Intake:
    The higher the energy intake, the less dietary protein is required to
    maintain nitrogen balance. Increasing the carbohydrate and fat content
    of the diet provides calories that do not stress the compromised
    excretory capacity of the kidney. Patients with acute renal failure,
    however, are often unable to tolerate high carbohydrate loads and may
    require insulin administration.


  • Regulating Phosphate, Calcium, and Magnesium Intake:
    Phosphate restriction is necessary to prevent the metabolic bone
    disease that often accompanies renal failure, phosphate levels can be
    regulated with phosphate-binding agents that cause dietary phosphate to
    be excreted rather than absorbed. Calcium may be administered as a
    supplement as needed. Excessive magnesium levels are not usually
    present unless magnesium-containing antacids are used, avoiding them or
    using magnesium-binding agents prevents toxic accumulation of this
    substance.



  • Supplementing Vitamins and Trace Elements:
    Supplemental water-soluble vitamins and trace elements are usually used
    to compensate for inadequate intake and losses in dialysis.


  • Providing Appropriate Counselling and Support:
    Diets for renal patients are based on contradictory principles (meet
    nutritional needs but restrict protein and phosphorus), are especially
    restrictive, and require careful monitoring of the patient's
    nutritional status. Thus, trained nutrition professionals are usually
    essential for dietary management.

Food Labels: Evidence related to the role of dietary
factors in renal disease currently holds no special implications for
change in policy related to food labeling.
