Understanding Gastrointestinal Physiology Tests :
Your digestive system breaks down food and absorbs nutrients. When it does not work properly, you may feel pain, heartburn, or discomfort.
That is why doctors use gastrointestinal physiology tests to find the cause. These tests are safe and help check how well your digestive system works.
At LSDC, we offer three main tests:
Private Oesophageal Manometry, Reflux Test (24-hour pH and Impedance), and a Combined Oesophageal Manometry and Reflux Test.
Each test gives your doctor useful information to plan the right treatment.
Private Oesophageal Manometry
This test shows how the muscles of your oesophagus move food into the stomach.
During the test, a thin tube with small sensors goes gently through your nose and into your oesophagus.
The sensors record pressure as you swallow.
As a result, doctors can see if your muscles work as they should.
This test helps when you have:
Trouble swallowing
Chest pain not linked to the heart
Achalasia, a problem where food has trouble reaching the stomach
In addition, manometry helps your doctor plan the most suitable treatment for your symptoms.
Therefore, it plays an important role in managing swallowing and chest discomfort.
Reflux Test (24-Hour pH and Impedance)
If you often have heartburn or a sour taste, you may need a reflux test.
This test checks whether acid moves up from the stomach into the oesophagus.
A small, soft tube goes through the nose and stays in place for one day.
It measures two things:
pH levels, to detect acid
Impedance, to track the movement of liquid or gas
Because of this, your doctor can see how often reflux happens and how strong it is.
As a result, the test helps confirm GERD and other reflux-related conditions.
It also shows if your current treatment is truly effective.
Combined Oesophageal Manometry and Reflux Test
Sometimes, symptoms suggest both reflux and movement problems.
In such cases, doctors may recommend the combined test.
This single test measures both muscle movement and acid levels at the same time.
Therefore, it gives a full picture of how your oesophagus works.
In addition, it saves time by combining two studies in one.
It is helpful for:
Complex swallowing issues
Chest discomfort
Ongoing reflux despite medication
