Kidneys are the main organs that are responsible for filtering any waste products found in blood. They are also essential when it comes to regulating blood pressure, balancing electrolyte and balancing the production of red blood cells in your body.
The symptoms of kidney failure occur as a result of the buildup of excess fluids and waste products in one’s body. The buildup ends up causing confusion, swelling, difficulty in breathing and overall body weakness.
Kidney failure occurs as a result of an acute situation that ends up harming the kidneys. It may also be caused by a chronic disease that completely destroys the kidneys hence making them cease functioning.
A complete kidney failure occurs when both kidneys are damaged thus forcing them to stop functioning. Most people have two kidneys hence when one stops functioning; it can be removed leaving the other one to operate as usual. If both of the kidneys fail to function due to injury or damage, a donor may be requested to offer one for transplanting.
The cause of kidney failure is always categorized depending on the location of your injury. They are classified into Prerenal causes and Postrenal kidney failure causes.
Prerenal Kidney Failure Symptoms
Prerenal kidney failure causes occur as a result of a decrease in the supply of blood to your kidneys. Examples of kidney failure causes include:
- Low blood volume caused by blood loss
- An abnormal blood flow in your kidneys
Postrenal kidney failure symptoms
Postrenal kidney failure causes are a result of the factors that inhibit or limit the outflow of urine. They may be as a result of:
- Obstruction of the ureter or bladder which causes back pressure in the kidneys
- The urethra may also be blocked by prostate cancer making it difficult for the bladder to be emptied
- Tumors in the abdomen can also limit the outflow of urine as it may end up blocking the ureter
- In patients that have one kidney, the development of kidney stones in the remaining kidney can lead to kidney failure.
Symptoms of kidney failure
At first, no symptom will appear depicting any sign of kidney failure in your body. This stage is commonly referred to as the asymptomatic stage of kidney failure. The symptoms depend on a person since in some it may occur in the first stage while for others it is witnessed in the final stage known as End-Stage Renal Failure.
Once the kidney loses the ability to operate, symptoms start showing up since they will no longer regulate water in your body, clean waste products or even promote the production of red blood cells in the body. Some of the symptoms of kidney failure include:
A person may end up feeling tired, losing concentration or even losing energy in the body. When your kidneys seize to function, it results in the buildup of impurities and toxins in the blood. This may end up making a person to feel tired and very weak thus reducing their productivity levels.
Many people with kidney failure have also been reported to have anemia that also leaves them tired and weak.
- Difficulty when it comes to sleeping
When your kidneys are not filtering toxins as required, it results in their accumulation in your blood rather than leaving the body in form of urine. This action may end up making it difficult for a person to easily fall asleep.
- Dry and itchy skin
A normal kidney has many roles in the body including removing wastes, making red blood cells and keeping the bones strong enough. Patients suffering from kidney failure tend to develop mineral and bone diseases that make their skin dry and itchy. This is as a result of the kidney not maintaining the correct balance of nutrients and minerals in your blood.
- Urge to Urinate
Kidney failure may make one to constantly visit the washrooms especially during the wee hours of the night. Once the filters of the kidney have been damaged, urine is easily released into the bladder thus increasing the urge to urinate. In some people, this symptom can be as a result of a urinary tract infection or an enlarged prostate in men.
Change in urine color
A person suffering from kidney failure may pass out urine that is extra clear due to the inability of the kidney to effectively filter out toxins and wastes.
The urine may also have excessive bubbles indicating the presence of proteins. This foam is sometimes similar to the one witnessed when an egg is being scrambled.
- Persistent puffiness around your eyes
Puffiness may sometime be witnessed around the eyes as a result of protein leakage. When large amounts of protein are leaked into urine instead of being absorbed by the body, your eyes end up becoming puffy.
- Poor Appetite
Poor appetite is a very general symptom depicting kidney failure. People with kidney failure, may have a changed feeling of hunger than before thus eating less than normal. The cause of poor appetite can be attributed to the buildup of toxins that is as a result of the reduced kidney function.
- Cramping Muscles
Once your kidney fails, you will have an electrolyte imbalance in the body. This leads to low calcium levels or low phosphorus levels in your body which in turn makes the muscles to start cramping.
- Swollen ankles and feet
A decrease in the operation of your kidney can lead to the retention of sodium that may end up causing swelling in your ankles and feet. However, this must not be taken as the main symptom of kidney failure since it can also be a sign of liver disease, chronic leg vein disease or a heart disease.
- Nausea and vomiting
Since the kidney will no longer remove impurities from the blood, one may start experiencing nausea or constant vomiting.
Other symptoms of kidney failure include:
- Unusual thirst
- Change in menstrual cycle interval
- Problem in digestion
- Blood in urine.
