What does pumping your stomach do?

Gastric lavage, commonly referred to as pumping your stomach, is a medical procedure in which the contents of the stomach are removed using a nasogastric tube. It is primarily performed to treat or prevent poisoning or intoxication caused by the ingestion of harmful substances, such as drugs, toxins, or corrosive materials.

When someone ingests a potentially harmful substance, pumping the stomach aims to:

1. Empty the Stomach: By inserting a tube into the stomach and suctioning its contents, gastric lavage empties the stomach and removes the unabsorbed toxins or harmful substances. This reduces their further absorption into the bloodstream and helps prevent systemic toxicity.

2. Limit Absorption: Prompt removal of ingested substances before they can be absorbed by the stomach lining can reduce the amount of toxic material entering the bloodstream.

3. Prevent Complications: Gastric lavage can help prevent potential complications and long-term effects caused by the absorption of harmful substances. For example, it may help prevent organ damage, respiratory distress, or other systemic effects.

4. Obtain Sample for Analysis: In some cases, the contents obtained during gastric lavage may be sent for laboratory analysis to identify the specific substance ingested and guide further treatment or management.

5. Administer Treatment: If necessary, medications or antidotes may be administered directly into the stomach through the nasogastric tube during or after gastric lavage.

It's important to note that gastric lavage is not always necessary or appropriate in every case of poisoning or intoxication. The decision to perform gastric lavage is made by a medical professional based on the type and amount of substance ingested, the individual's condition, and the potential risks associated with the procedure.
