Why would someone have paracentesis?

Paracentesis is a procedure that involves inserting a thin needle into the abdominal cavity to drain fluid. It is typically performed when there is a build-up of fluid in the abdomen, which is also known as ascites.

Ascites can be caused by a variety of conditions, including:

* Cirrhosis: A chronic liver disease in which scar tissue replaces healthy liver tissue.

* Heart failure: A condition in which the heart is unable to pump blood effectively.

* Kidney failure: A condition in which the kidneys are unable to filter waste products from the blood.

* Cancer: Malignant tumors can cause fluid to build up in the abdomen.

* Tuberculosis (TB): A bacterial infection that can affect the lungs and other organs.

Symptoms of ascites include:

* Abdominal swelling

* Weight gain

* Shortness of breath

* Nausea

* Vomiting

* Fatigue

Paracentesis can be used to:

* Diagnose the cause of ascites: The fluid that is drained during paracentesis can be tested for signs of infection, cancer, and other conditions.

* Relieve symptoms: Paracentesis can help to relieve the symptoms of ascites, such as abdominal swelling and shortness of breath.

* Improve quality of life: By relieving symptoms, paracentesis can help to improve the quality of life for people with ascites.

Paracentesis is a relatively simple procedure that is typically performed in a doctor's office or clinic. The procedure usually takes about 30 minutes and is typically well-tolerated.
