GI motility refers to the progression of food, fluids and waste through the digestive tract. Motility problems include acid reflux, chronic constipation, irritable bowel syndrome, fecal incontinence and bacterial overgrowth. Manometry is a measurement technique to diagnose motility orders.
Gastroesophageal reflux disease (GERD), Gastric reflux disease, or Acid reflux disease is defined as chronic symptoms or mucosal damage produced by the abnormal reflux in the esophagus.
This is commonly due to transient or permanent changes in the barrier between the esophagus and the stomach. This can be due to incompetence of the lower esophageal sphincter (LES), transient lower esophageal sphincter relaxation, impaired expulsion of gastric reflux from the esophagus, or a hiatus hernia. If the reflux reaches the throat, it is called laryngopharyngeal reflux disease.
GERD is a chronic condition and may lead to more serious medical conditions, but is treatable. To measure and diagnose GERD MMS offers easy to use pH and pH-Impedance recorders.
What is Impedance?
Impedance measurement can be used to detect GERD (Gastro Esophageal Reflux Disease) and distinguish acid and weakly acidic refluxes causing symptoms.
Gastro-Esophageal Reflux Disease (GERD) is caused by the reflux of gastric contents into the esophagus. Typical patient symptoms are heartburn, regurgitation, and chest pain. These patient groups are often on PPI medication, but non-acidic reflux can still cause symptoms.

Traditional pH recording only records acidic pH reflux episodes. Impedance-pH detects both acidic and non-acidic reflux episodes.
Combined Impedance-pH recording is clinically useful in the evaluation of symptoms under PPI therapy, as well as for hoarseness, unexplained cough, and applications of particular interest.
