Description

GASTROINTESTINAL DIAGNOSTIC SYSTEM

The present disclosure relates to a gastrointestinal diagnosis system, and more particularly, to a gastrointestinal tract diagnosis device and a gastrointestinal tract diagnosis server for diagnosing a user's gastrointestinal tract.

Patients with digestive disorders such as indigestion or irritable bowel syndrome may complain of repetitive and various functional gastrointestinal symptoms such as abdominal discomfort, bloating, abdominal pain, constipation, and diarrhea.

These functional gastrointestinal symptoms may be repeatedly expressed even in the absence of diseases such as cancer, ulcers, or inflammation that are detected by examinations such as ultrasound or endoscopy. As a result, patients with digestive diseases visit the hospital whenever they feel discomfort in the abdomen, and frequent visits often incur a lot of medical expenses.

Conventionally, techniques related to invasive methods have been mainly used to diagnose functional gastrointestinal symptoms. However, these techniques generally required high equipment cost and specialized knowledge in performing the diagnosis. In addition, the invasive method also has a risk of causing a wound to the patient depending on the skill of the person performing the procedure.

Therefore, there is a demand for the development of a non-invasive method-based gastrointestinal diagnostic system.
