Kidney failure

Types and Causes of Kidney Failure

Your kidneys are one of the most significant organs in the body. They are a pair of organs located towards your lower back and serve the purpose of filtering your blood to remove toxic and waste substances from the body. The toxic substances can be detrimental to your health if they are not removed out of the body.

What is a kidney failure?

Kidney failure is the condition where both of your kidneys or just one of them cannot serve their function to the required level of performance. This can be brought about by a myriad of factors that may interfere with the health and proper function of your kidney. Some of them include:

  • Kidney trauma
  • Some acute and chronic diseases
  • Toxic exposure to environmental pollutants
  • Severe dehydration

When your system is burdened with toxins and dangerous wastes resulting from a kidney failure, what follows are life threatening conditions that can be dangerous to your health. This is the reason why you should always seek the services of a doctor the moment you realize you have a kidney problem.

What causes kidney failure?

The following factors could predispose you to kidney failure

  • Loss of blood flow to the kidney

Kidney failure is often prompted by a sudden loss of blood flow to the kidneys. Some of the diseases and conditions that may lead to loss of blood flow to the kidneys include:

  • Heart attack
  • Severe burn
  • Dehydration
  • Liver failure
  • Allergic reactions
  • Urine elimination problem

When your body finds it difficult to eliminate urine from the system, there is a consequent build up and overloading of the kidneys. Certain cancers can lead to blockage of urine passageways. Such cancers include prostate cancer, cervical cancer, colon cancer, and bladder cancer. Other conditions which that can interfere with urination include

  • Trauma on the nerves controlling urination
  • Blood clots within the urinary tract
  • Kidney stones
  • Enlarged prostate

Other causes

Certain diseases and conditions can lead to kidney failure. They include:

  • A clot of blood in the kidney
  • Drug and alcohol
  • Dyes used in certain imaging tests
  • Chemotherapy drugs (medications that treat autoimmune diseases and cancer)
  • Overload of toxins from heavy metals
  • Thrombotic thrombocytopenic purpura. (A disorder that causes blood clot in tiny vessels)

Types of kidney failure

Below are the types of kidney failure

Acute Prerenal kidney failure

Without enough flow of blood into the kidneys, the kidneys find it difficult to filter out the toxic wastes hence the occurrence of acute perennial kidney failure. This problem is usually solved once the problem leading to the low supply of blood has been determined.

Acute intrinsic kidney failure

Direct trauma causes this kind of kidney failure to either one of the kidneys or both of them. An accident or physical impact can lead to the trauma. Its causes are ischemia and toxic overload making it difficult for the kidney to perform its function in the right manner. Ischemia may be caused by

  • Obstruction of renal blood vessel
  • Shock
  • Severe bleeding
  • Glomerulonephritis

Chronic Prerenal kidney failure

This is the condition where the kidney begins to shrink thus losing its function. The primary cause of this is insufficient blood flowing into the kidneys.

Chronic intrinsic kidney failure

This usually occurs when there is a long-term damage to the kidneys as a result of intrinsic kidney diseases. Direct trauma causes these intrinsic kidney diseases to the kidneys like severe bleeding or insufficient oxygen.

Chronic post renal kidney failure

This is caused by a long-term blockage of the urinary tract thus hindering urination. The consequent is pressure which in turn cause kidney failure.

Understanding High Blood Pressure

For many, the closest they have ever come to understanding hypertension is the medical shows they watch. Unfortunately, some of these programs have inaccurate information and therefore cannot be trusted. Should you rely on them, you will be lost and find an entirely wrong information of high blood pressure. This will not give you accurate information about the disease and what it can mean to you. Understanding blood pressure is supposed to be a priority for all adults. Currently, the condition is endemic with one in three adults suffering from it. The following is a quick guide the disease and the treatments available.

What is blood pressure?

Essentially, blood pressure is the force with which blood circulates through your veins and blood vessels. The reading of your blood pressure is usually taken by an instrument known as a manometer, an instrument which looks like a strip of rubber attached to a thermometer. Alternatively, a sphygmomanometer is used for measuring the pressure. As your heart beats, your blood pressure records a variation in pressure i.e. maximum, scientifically known as systolic, and minimum, known as diastolic pressure.

What is classified as high blood pressure and low blood pressure?

High blood pressure, also known as hypertension is the instance where the blood pressure shoots from a regular rate of 90-119 systolic pressure and a diastolic pressure of 60-79 up to 120-139 and 80-89 in the case of prehypertension. As the condition advances, the blood pressure records 140-159 and 90-95 for systolic and diastolic pressure respectively. Low blood pressure is the instance where it is below 90 systolic over 60 diastolic.

Consequences of hypotension and hypertension

Hypertension can result in a variety of unpleasant things happening in your body. Some of the effects include

• Heart attacks

• Burst blood vessels in the eye

• Drowsiness

• Kidney failure

• Confusion

• Nausea

Causes of high blood pressure

Even though there is not yet a definite cause of the condition, some behaviors have widely been associated with it. The behaviors include

• Sedentary life

• Diets with a high content of animal fats and salt

• Unmanaged stress

• Obesity

High blood pressure treatment

Currently, there exist more than two hundred separate brands of medication which aim to solve the problem of high blood pressure. There has not been a single drug manufactured that can permanently cure the condition, and so doctors often prescribe a combination. After that comes a period of adjusting doses to achieve optimal effects on blood pressure while at the same time alleviating the side effects of the drugs used for treatment. The primary objective of the drug is to control the condition and not necessarily to cure it. Once you get the conditions and start using the medication, you are on drugs for life.

High blood pressure medication comes in four different classes, each of which has subcategories. The classes include

• Diuretics

• Beta blockers

• Ace inhibitors

• Calcium channel blockers

What’s the alternative treatment and control of high blood pressure?

Many people for lifestyle change in a bid to control and treat this condition. It is possible to reduce significantly high blood pressure. What would make this possible is diet adjustment, taking up daily exercise as well as managing stress. However, just as in medication, once you take up a lifestyle of healthy living, there is no going back.

High blood pressure is a condition that could catch up with just about anyone. Knowing about it will greatly help you to know how to take care of it.
