Why Is There Less and Less Urine After Dialysis

Why Is There Less and Less Urine After DialysisWhy is there less and less urine after dialysis?

Dialysis is the process of using a special machine to filter waste from the blood instead of the kidneys. It reduces the amount of urine a person normally produces each day.

This happens because the blood is filtered and fluid is removed during dialysis, reducing the traditional role of the kidneys. As a result, many dialysis patients produce very small amounts of urine. However, dialysis does not prevent some people from urinating normally; It will only reduce the total amount of urine, so he or she may only need to urinate once a day, which is not dangerous. Some dialysis patients produce one cup or less of urine per day, although the amount often depends on the underlying cause of kidney failure. Some patients continue to produce a normal volume of urine, which helps control their fluid balance.

Here are some causes of less urination for dialysis patients.

  1. Hemodialysis causes the serum creatinine, urea nitrogen and other uremic substances in the body to decrease too fast within a short period of time, leading to the swelling and necrosis of renal cells, especially the damage of renal tubular epithelial cells. The aggravation of renal injury can make urine volume reduce.
  2. Complications during hemodialysis include infection, hypotension, anaphylaxis and shock can cause further kidney damage.
  3. Loss of blood during hemodialysis can aggravate anemia so as to make renal ischemia, anoxia and necrosis worse.
  4. Hemodialysis reduces the concentration of uremia substances such as serum creatinine and urea nitrogen in the body, and the original osmotic diuretic effect disappears or weakens, resulting in reduced urine volume.
  5. Hemodialysis increases the effective circulation of the heart and aggravates the burden on the heart, causing heart failure, which affects the blood supply and oxygen supply to the kidney, and aggravates the renal injury.
  6. Dehydration during hemodialysis leads to decreased blood volume, and decreased blood flow to the kidneys so as to cause oliguria.

With the reduction of urine, your life quality will be reduced, because you can not drink plenty of water. The feeling of thirsty can make you feel very uncomfortable.

How to increase urine volume for dialysis patients?

Here some therapies you can try, including Acupuncture, Moxibustion, Enema Therapy, Steam Therapy, Medicated Bath, Foot Bath, etc. After about one month’s treatment, you will see the result.
