Oliguria is one of the most common signs of urine infection, excessive loss of fluids and fluids, the presence of cysts or tumors in the urethra or bladder, and other problems. If you are interested in knowing all about oliguria: what it is, its causes and symptoms, and what its treatment is, continue reading this FastlyHealarticle in which we detail it for you.

What is oliguria, and what are its values

Oliguria is the decrease in urinary secretion and excretion. It is the condition in which the body is producing and expelling less urine than usual. Therefore, it is not a disease in itself but an effect of some disorder in the body and a symptom of some diseases. Thus, this sign, which mainly indicates problems in urinary health, especially kidney health, can occur in anyone, regardless of gender or age.

oliguria values

When the doctor wants to know to what degree we are suffering this decrease in urine production since this helps diagnose the origin of this symptom. Doctors consider that oliguria begins when the diuresis or urine secretion is less than 500 ml/day, although some believe it happens in less than 400 ml/day. If this value becomes less than 100 ml/day, it is anuria, defined as the absence of urine. Instead, it is polyuria when the usual urine output is doubled or tripled.

Causes of oliguria

Oliguria can have a prerenal, renal, or postrenal origin. The disease or problem causing it is before the kidneys occur in the kidneys themselves or after them.

The conditions or diseases that can cause oliguria are not only characteristic of the urinary system, but other conditions affect the body that can cause it to secrete less urine than average. Among the leading causes of oliguria, we find the following:

  • Dehydration: if the body has lost fluids, it is normal for urine production to decrease, a case of prerenal oliguria. This typically happens in cases of diarrhea, vomiting, excessive sweating, bleeding, etc.
  • Glomerulonephritis: encompasses various kidney diseases that reduce the ability of these organs to produce and excrete fluids with waste and waste. For example, it may be a nephritic syndrome.
  • Acute tubular necrosis: it is a problem that occurs when the tissues of the tubules or ducts of the kidneys themselves become poor, are damaged, and die. Therefore, it is a severe kidney problem of which one of the main symptoms is decreased urine.
  • Stones, stones, and other urinary obstructions: when there are bodies that obstruct the kidneys, the bladder, or the urethra, the first thing we usually notice is the lack of considerable reduction of this fluid. In some cases, you may feel the need to go to the bathroom, and in others, you may not. Thus, whether they are kidney stones or stones, cysts or tumors, it is necessary to find them and treat them, even with surgery.
  • Urine infection: when the urinary infection is severe, there is a constant feeling of wanting to go to the bathroom, but there is also oliguria.
  • Pregnancy and menopause: in these two stages of female life, the production and expulsion of urine can be reduced.
  • Some medications: just as some are highly diuretic, some do the opposite and, either directly or as a side effect, reduce the activity of the urinary system.

Symptoms of oliguria

As this condition itself is a symptom, we can instead talk about the main signs of oliguria to be able to recognize that we suffer from it:

  • Significant reduction in the amount of urine passed in a day.
  • Increased frequency of the urge to urinate.
  • General malaise.
  • I feel heaviness throughout the body, especially in the legs and arms.
  • Pain in the lower abdomen and abdomen.
  • Rapid pulse
  • Tenths and fever.
  • Dizziness, nausea, vomiting
  • Swollen ankles.

Not all these signs should co-occur since only with a significant reduction in the daily amount of urine, reaching the values ​​mentioned above is enough to say that you suffer from oliguria. However, the other symptoms are expected simultaneously that this condition occurs, and it is easy to present them at the same time or that they appear after several days since they are part of the symptomatic pictures that usually produce the diseases that cause oliguria before commenting.

Treatment for oliguria

The treatment for oliguria or decreased urine output should be aware of two parts. One aimed to recover the lack of liquid that may have been lost, and the other party ultimately depended on the underlying cause because treating the origin solved the condition. These are some guidelines that are usually followed as treatment in these situations, but only the doctor will be the one to decide which is the best for each patient:

  • Drink plenty of fluids, including diuretic infusions like horsetail or dandelion.
  • If necessary, use the intravenous serum.
  • Medicines that stimulate urine production.
  • Specific medications to treat the underlying cause.
  • If there is kidney failure, it is also necessary to undergo dialysis treatment.
  • Treatment to remove stones or stones in the kidney, bladder, or urethra, if this is the cause, and surgery may even be necessary.
  • Surgery for cysts, polyps, or tumors.
