What you might feel, see and experience as indicators of poor kidney function

on Thu 9 Mar


Most of us recognise the importance of our kidneys without perhaps fully understanding their role in our body.  So on this, World Kidney Day, I thought I’d explain.


Bean-shaped, these hard working organs sit against your back muscles in the upper abdominal area. From there they filter up to 150 quarts of blood daily and their function is five-fold:


  1. They clean the blood by filtering out toxins and waste
  2. They remove excess fluid by adding it to waste products thus creating urine
  3. They keep your blood pressure regular
  4. They manage the production of Vitamin D
  5. They maintain the balance of salt and mineral levels in our blood


Given their vital function it’s important to watch out for any indicators that all is not well - so here are the signs to watch out for starting with


How you might feel:

You may notice that you have less energy and feel more fatigued. This is either due to a build-up of toxins or to a common side effect of kidney disease which is anaemia


This build-up of toxins may also lead to you finding it difficult to sleep and may lead to you having less appetite than usual.


What you might see

Your eyes may look puffy (this is due your body losing protein rather than retaining it)

Your feet and ankles may appear swollen – probably due to sodium retention


What you might experience

Your skin may feel dry and itchy because kidney disorders can lead to dehydration which leads to dry skin. This can be coupled with the fact that the oil producing glands of the skin become inhibited leading to the skin flaking or itching


You may experience your muscles cramping due to an electrolyte imbalance



Urine indicators

You may need to pass urine more frequently – especially during the night – and your urine may be more foamy.  By this I’m referring to excessive bubbles which may require several flushes to dispel from the toilet (due to protein in the urine)


You may also see blood in the urine this is caused by the kidney’s inability keep blood cells in the body post filtration


Some of these symptoms are not solely down to kidney disease so please be mindful that


  • Excessive urination can also indicate an enlarged prostate or a urine infection


  • Blood in the urine can also indicate an infection, kidney stones or tumours


  • Swelling in the feet and ankles can indicate heart disease, liver disease or chronic leg vein problems.


The risk factors for kidney disease


  • Diabetes
  • High blood pressure
  • Family history of kidney disease
  • Increasing age
  • Obesity
  • Kidney cancer
  • Polycystic kidneys
  • Autoimmune conditions


Diagnosis and Treatment

A simple urine and blood test will reveal the presence or otherwise of kidney disease.   Although there is no cure for chronic kidney disease treatment is about controlling the disease which has caused it in order to slow further damage.


I do hope you find this helpful, if you have any concerns do go to your GP.
