How a Healthy Kidney Works
The kidney is a complex filtration system with precisely divided functions. It can be compared to a double-bent pipe under a sink. In the loop of Henle, concentrated urine is formed and then further filtered until the remaining fluid consists mainly of water, urea, and sodium chloride. Each section follows exact instructions – excrete this, retain that. A healthy kidney does not allow even a drop of sugar or protein to pass into the urine.
When the Kidneys Ask for Attention
Shivering, chills, burning, or cutting pain during urination – these are obvious signs of inflammation. But tired kidneys speak much more quietly. Their fatigue is easily lost amid overall body exhaustion. When the body does not receive enough fluids, pain may appear in the flank area. This is often attributed to sports, gardening, or long periods of sitting.
When Kidneys and Blood Pressure Do Not Work Together
High blood pressure and reduced kidney function are closely linked. Not only the heart but also the kidneys are affected by pressure. Similar to old pipes in a house, where excessive pressure eventually causes damage, kidney function can gradually deteriorate. Unfortunately, many people seek medical help only when the organ is already failing. Some patients are even diagnosed only when dialysis becomes necessary.
How to Protect Your Kidneys
• Maintain proper hydration – drink 1.5–2.5 litres of fluids daily, more in summer. Pure water should be the basis, supplemented with teas and mineral water.
• Avoid getting chilled – cold feet can irritate the urinary tract and may be the first step towards inflammation.
