Has anyone cured their glomerulonephritis?

Recognize and treat kidney weakness

Status: 05.02.2021 5:16 p.m.

More and more people are suffering from kidney weakness. The insidious: At the beginning, the disease does not trigger any noticeable symptoms. Early treatment is important.

The kidneys clean the blood, regulate blood pressure, the salt and water balance and produce important hormones. They do their work unnoticed, even when things get worse and worse. More and more people develop progressive kidney weakness without realizing it. In Europe, ten percent of adults already have chronic kidney disease and in many cases are ultimately dependent on artificial blood washing (dialysis) or a kidney transplant.

Risk factors for kidney failure

In particular, high blood pressure and diabetes damage the very fine vessels of the kidneys in the long term. In addition, obesity affects them. People who are very overweight (obese) often have several risk factors for kidney failure. For example, the fatty tissue in the abdominal cavity forms inflammatory hormones, which also endanger the kidneys. Other serious consequences are cardiovascular disease and reduced life expectancy.

Obese children are more likely to develop kidney weakness later on

In the meantime, more and more children and adolescents are very overweight and suffer from type 2 diabetes. They run the risk of being dependent on regular automatic blood washing at the age of 30 to 45 - for the rest of their lives.

Kidney weakness from smoking or medication

Cigarettes, an unhealthy diet high in pork, and pain relievers such as ibuprofen or diclofenac taken for a long time can also cause massive damage to the kidneys.

Kidney damage in autoimmune diseases

Autoimmune diseases can also attack the kidney. In glomerulonephritis, the autoimmune process turns exclusively against the kidneys. In some systemic autoimmune diseases, the kidneys are affected - vasculitides, i.e. inflammation of the blood vessels, and collagenoses, which attack the connective tissue, should be mentioned in particular. The most common diseases with kidney involvement include granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and systemic lupus erythematosus (SLE).

Symptoms of kidney weakness

Kidneys naturally weaken as they age. Symptoms that can indicate kidney problems include:

  • high blood pressure
  • sharp headache
  • Water in the legs
  • Skin that tightens
  • Foam on the urine

The following symptoms may occur in end-stage renal failure:

  • high blood pressure that can no longer be adjusted
  • Decrease in the amount of urine
  • Water retention (edema)
  • shortness of breath
  • nausea
  • Vomit
  • Loss of appetite
  • irregular heartbeat
  • Drowsiness
  • sleepiness
  • cramps
  • coma

Examination for kidney weakness

Decreasing kidney function can be detected with blood and urine tests:

  • The provides a first hint Creatinine level in blood. Creatinine is a breakdown product of the acid creatine, which supplies the muscles with energy. It builds up in the blood when the kidneys are not working properly. However, the creatinine value only rises when the kidney function is already restricted by more than 50 percent.
  • Also an increased Protein excretion in the urine suggests kidney damage.
  • The more complex laboratory tests are more sensitive to this Protein cystatin C and those freely circulating in the blood Urokinase receptor suPARthat indicate a kidney problem long before symptoms appear.

Treat kidney failure

Kidney damage can usually not be reversed. If kidney damage is detected in good time, the progression of the disease can often be slowed down with medication and the right diet. Anyone who suffers from diabetes, obesity and high blood pressure should have their kidney values ​​checked regularly and change course as soon as possible: Lots of exercise and a healthy diet can help prevent the disease from getting worse and thereby delay serious kidney damage.

Renal insufficiency: dialysis or transplant

If the organ function has already decreased to less than ten percent, only artificial blood washing (dialysis) usually helps. The only alternative is a kidney transplant, but donor organs are in short supply.

This is how the kidney filters the blood

In the kidneys, around three million kidney corpuscles filter harmful substances out of the blood. So-called foot cells form a special grid-like structure in the kidney corpuscles: healthy foot cells allow small molecules such as water and nitrogen compounds to pass through, which are released with the urine. Large molecules like blood cells and protein are not let through and stay in the blood. In a diseased kidney, the lattice structure of the foot cells is much more permeable: the blood loses large molecules, such as important proteins and vitamins.
