Kidney failure increases level of urea in the blood (uraemia). This urea is broken down to ammonia in the saliva causing urine-like bad breath called ammonia breath. It is also usually associated with an unpleasant metallic taste (dysgeusia) in the mouth.
This is a symptom of kidney disease which is a definite cause for concern. There may be other reasons, but it is advisable to visit your doctor in case you notice it.
Kidney disease causes fluid to build up in the lungs. And also, anaemia, a common side-effect of kidney disease, starves your body of oxygen. You may have trouble catching your breath due to these factors.
Your kidneys produce a hormone called erythropoietin which helps make red blood cells that carry oxygen. In kidney disease lower levels of erythropoietin causes decreased red blood cells in your body resulting in anaemia. There is decreased oxygen delivery to cells causing generalised weakness and extreme fatigue. Read more about the Top reasons for fatigue
Anaemia associated with kidney disease also depletes your brain of oxygen which may cause dizziness, trouble with concentration, etc.
Most people are not aware of the fact that kidney diseases can be silent killers. They may not show any symptoms for a long time till the situation becomes critical. (Why is it silent?) Even young people are now prone to it. It is important to recognize the symptoms of kidney diseases to catch them early. There are many reasons why kidney disease is caused. The most common causes are diabetes and hypertension. Even an unhealthy lifestyle with a high calorie diet, certain medicines. lots of soft drinks and sugar consumption can also cause kidney damage.
Sometimes you have difficulty or feel pressure or pain while voiding. Urinary tract infections may cause symptoms such as pain or burning during urination. When these infections spread to the kidneys they may cause fever and pain in your back.
The first symptom of kidney disease is changes in the amount and frequency of your urination. There may be an increase or decrease in amount and/or its frequency, especially at night. It may also look more dark coloured. You may feel the urge to urinate but are unable to do so when you get to the restroom.
If you have kidney disease you may feel cold even when in a warm surrounding due to anaemia. Pyelonephritis (kidney infection) may cause fever with chills.
Kidney failure causes waste build-up in your blood. This can causes severe itching and skin rashes.
Kidneys remove wastes and extra fluid from the body. When they are unable to do so, this extra fluid will build up causing swelling in your hands, feet, ankles and/or your face. Read more about Swelling in the feet .
The build-up of waste products in your blood in kidney disease can also cause nausea and vomiting. Read more about 13 causes for nausea
Some cases of kidney disease may cause pain. You may feel a severe cramping pain that spreads from the lower back into the groin if there is a kidney stone in the ureter. Pain may also be related to polycystic kidney disease, an inherited kidney disorder, which causes many fluid-filled cysts in the kidneys. Interstitial cystitis, a chronic inflammation of the bladder wall, causes chronic pain and discomfort.
