The Ascites it is the accumulation of fluid within the abdomen, in the cavity surrounding the digestive organs. It is not a disease in itself, but a sign that can appear in various pathologies, especially those related to the liver.
When fluid accumulates in sufficient quantities, the patient may notice an increase in abdominal volume, a feeling of bloating or heaviness. In more advanced stages, it can cause discomfort when moving or even difficulty breathing.
It can appear in situations such as:
- Chronic liver disease (cirrhosis): The most frequent cause.
- Oncological problems: such as abdominal or digestive tumours.
- Heart or kidney failure: that promote fluid retention.
- Inflammatory or infectious processes: less frequent, but possible.
Practical example: Progressive abdominal distension
A person might notice their abdomen increasing in size without gaining weight overall. They may feel more bloated, have difficulty buttoning up clothes, or experience a feeling of internal pressure.
although it may initially be confused with gas or bloating, the Ascites It implies the actual accumulation of fluid. In these cases, an ultrasound scan can confirm its presence and direct the investigation towards the cause, which in many cases is related to the liver.
Ascites and its importance in diagnostic gastroenterology
The appearance of ascites is usually a sign that there is an underlying problem that needs to be investigated. In the digestive field, it is especially related to Liver cirrhosis, where the liver loses its ability to function correctly and the body's fluid balance is altered.
That's why, more than the liquid itself, it's important to understand why has it occurred. Its presence can indicate advanced liver disease or other pathologies requiring specific treatment.
The study usually includes imaging tests such as ultrasound, blood tests, and in some cases, fluid extraction (paracentesis) to analyse it.
A frequent doubt is thinking that ascites is simply “fluid retention.” In reality, it is usually a sign of an underlying disease that requires a thorough medical evaluation.
