Gastrointestinal function tests: oesophageal pH test: Simple

The pH value in the lower part of your esophagus was measured.

The oesophagus or gullet connects the mouth with the stomach. It is a muscular tube. The muscles in the oesophagus move food into the stomach. The oesophagus is usually closed by a sphincter muscle at the junction to the stomach. This is meant to prevent the stomach contents and gastric acid being regurgitated into the oesophagus. Only during swallowing does the oesophagus briefly open its sphincter muscle to the stomach. The stomach acid is produced in the stomach. The stomach acid is involved in digesting food.

To measure the pH value, a thin tube is pushed through the nose and throat into the lower part of the esophagus. The tube is used to measure the pH value over a certain period of time, and this is recorded by a small device. The pH value indicates how acid or alkaline a fluid is.
