pH Importance for Digestion: The Heidelberg Capsule test


Digestion begins with the sight and smell of food!  Food stimulates  saliva in the mouth. Saliva contains an Enzyme, called Amylase, which mixes with the food that is chewed.   Amylase breaks down  starches into a sugar the body can use. (More Amylase is made by the Pancreas in the Duodenum). Food is propelled into the Esophagus by swallowing. The Esophagus is a tube , which empties into the Stomach. The Stomach , a hollow, pouch-like structure begins the process of Digestion  The Stomach’s function is to  break food into smaller particles. The normal Stomach contains Hydrochloric Acid, Pepsin, Mucin, and the Intrinsic Factor, which is necessary to absorb Vitamin B-12. The Acid and Pepsin initiate Digestion .  BUT IF A PERSON DOES NOT HAVE ENOUGH STOMACH ACID OR IF THE PERSON HAS TOO MUCH STOMACH ACID, DIGESTIVE ISSUES CAN OCCUR! Stomach Acid has effects on Meats, Cheese, Fish, and other foods. It also helps Pepsin to change Proteins into Amino Acids. Very little of what is eaten is absorbed directly through the Stomach wall – only certain Minerals, Water and Alcohol. The Stomach then  empties it’s contents directly into the Small Intestine through the Duodenum. The Duodenum is a segment of the Small Intestine.  Bile from the Liver and Enzymes from the Pancreas, along with a physiologic Buffer, are secreted as needed into the Duodenum to mix with foods passing through the Small Intestine.

The small intestine  is lined with tiny, finger-like projections, called Villi. The normal pH of the Small Intestine is pH 7.0 (neutral) to pH 9.0 (alkaline). Liver Bile and Pancreatin from the Pancreas need this  neutral-to-alkaline condition in order to work properly for you in the breakdown of fats and converting proteins to Amino Acids.

We do not absorb proteins in the form that we have eaten them. They have to be converted by enzymatic action into Amino Acids. In healthy Patients, Amino Acids are absorbed into the bloodstream through the wall of the Small Intestine. There, they are transported to cells in every part of our bodies. The Amino Acids are the fundamental building blocks of life! Malabsorption, Stomach gas, belching, bloating, flatulence and Irritable Bowels can be dealt with much easier by your Doctor when he can monitor and record the pH levels of both your Stomach and Small intestine.

A large number of people (more than 30%) over the age of 60 have very little or no Hydrochloric Acid in their Stomachs. The presence of Hydrochloric Acid and Pepsin in the Stomach is essential to initiate digestion of foods we eat. Stomach hyperacidity, delayed emptying time, with subsequent highly acid Small Intestines, appears to be more common than the lack of acid (hypo-acidity) in all age groups.

The pH HEIDELBERG CAPSULE TEST is a test which, through the swallowing of a small pH Capsule on a string, can determine the acidity of the stomach.

The Heidelberg Monitoring and Recording System displays the pH in a Graph like form onto a computer screen, and your doctor is able to diagnose whether you have “too much” or “too little” acid in your stomach. Either scenario can interfere with your digestion!

How does the Heidelberg pH capsule System work?

The Heidelberg pH capsule is a high-frequency transmitter. It measures 7.1 mm Diameter, by 15.4 mm Length, encapsulated within a special Polyacrylate (plastic) pH Capsule covering, and it is designed to be swallowed.

The pH Capsule operates at an average frequency of 1.9MHz. The power required to operate the transmitter is provided by a built-in, specially designed, physiologic battery. The Heidelberg Capsule is NOT RADIOACTIVE (Absolutely NOT). A miniature high-frequency transmitter, which is encapsulated for swallowing, continuously transmits the pH values from the Gastrointestinal Tract. The frequencies, which are transmitted by the pH Capsule, are picked up by the Medallion Transceiver (worn by you, the Patient). The Transceiver is a totally self-contained and wireless. This converts the Transmitted data to DIGITAL SIGNALS which are transmitted to a Computer to be displayed on a Monitor Screen in Graph form.  This graph gives your Doctor the information necessary to help you heal your digestive issues, and suggest a proper treatment protocol especially for YOU!


The HEIDELBERG CAPSULE IS AN  OFFICE PROCEDURE that replaces the need  for a  hospital based procedure.  The hospital based procedure requires anesthesia and placement of  a nasal-gastric tube. There is NO NEED FOR ANESTHESIA with the pH CAPSULE HEIDELBERG TEST!  The Heidelberg Capsule eliminates the need for the “Stomach Tube”. It allows your doctor the opportunity to simply and painlessly determine these vital pH data in his/her office.

The pH Capsule Diagnostic System is a Diagnostic Tool for Measuring the pH Levels in the Digestive Tract. The Heidelberg pH Capsule is a Technically advanced Micro-Electronic Diagnostic Tool that can Accurately Diagnose a Patient who may have Hypochlorhydria, Hyperchlorhydria, Achlorhydria, Pyloric Insufficiency, and Heavy Mucus.

Stomach acid issues are also implicated in allergies, osteoporosis/osteopenia , and malabsorption syndrome, which lead to chronic diseases! So, the need to correct the digestive issue is of utmost importance!

After the Heidelberg pH Capsule is activated, and Administered to the Patient, the pH Capsule will measure, and transmit the pH Levels, and the re-acidification time of the Stomach. The patient is given an alkaline challenge two to three times during the course of the test, to measure re- acidification timing. This means a small amount of salt and water is placed in the patient’s mouth and the patient is asked to swish and swallow the solution, while the measurements are continually assessed.

Professor H.G. Noeller performed a 1000 Patient Clinical Study, at the University of Heidelberg’s Department of gastroenterology, in Heidelberg, Germany. In his Published Study, he presented the efficacy of using a (Standardized orally Administered) 5 c.c. dose of an Alkaline Challenger on Fasting Patients. . This is the main and most meaningful purpose for the use of the Heidelberg pH Capsule Test.

Unlike other pH tests, which require the use of an invasive Nasal-gastric tube, or a Standard Endoscopic procedure, which in many cases may traumatize a Patient, the Heidelberg pH Diagnostic Test is accurate relatively non-invasive, and very  patient friendly! The pH Capsule is similar to the size of a Vitamin Capsule! Therefore, it is easy to swallow!

If you have digestive issues, and  would like to have the pH Heidelberg Capsule test performed  to detect what your digestive issues are, call Dr. Boyle’s office so that you can be evaluated today!
