Oliguria is characterized by a decrease in urine production, below 400 mL for every 24 hours, which is a consequence of certain conditions or diseases, such as dehydration, diarrhea and vomiting, heart problems, among others.
The treatment of oliguria depends on the cause of its origin, and it is necessary to treat the disease or condition that led to this symptom. In some cases, it may be necessary to administer serum in the vein or resort to dialysis.
Possible causes
Oliguria can be a consequence of:
- Certain conditions, which cause dehydration such as bleeding, burns, vomiting and diarrhea;
- Infections or injuries that can cause shock, and cause the body to reduce the amount of blood transported to the organs;
- Renal obstruction, which prevents the transport of urine from the kidneys to the bladder;
- Use of certain medications, such as antihypertensives, diuretics, non-steroidal anti-inflammatory drugs and certain antibiotics.
If oliguria occurs due to any treatment that the person is undergoing, it is important that the person does not discontinue any medication before talking to the doctor first.
What is the diagnosis
The diagnosis can be made through blood tests, computed tomography, abdominal ultrasound and / or Pet Scan. Find out what Pet Scan is and what it consists of.
How the treatment is done
The treatment of oliguria depends on the root cause. Therefore, it is important to consult the doctor when the person realizes that the amount of urine eliminated is less than normal.
In addition, if the person experiences a decrease in urine, they should be aware of other symptoms that may arise, such as nausea, vomiting, dizziness or increased heart rate, in order to avoid complications such as hypertension, heart failure, gastrointestinal disorders or anemia, for example.
In some cases, it may be necessary to administer serum in the vein to replace body fluids and resort to dialysis, to help filter the blood, until the kidneys are functioning again.
Avoiding dehydration is a very important measure in preventing oliguria as this is the main cause at the origin.
