What does an endoscopist do?

An endoscopist is the doctor responsible for carrying out tests that allow the interior of the digestive tract to be visualized. These procedures are essential for diagnosing conditions such as gastritis, gastroesophageal reflux, gastric ulcers and gastric and intestinal polyps.

At Instituto Medicina em Foco, Dr. Daniel Alvarenga uses modern equipment to perform Endoscopy and Colonoscopy, guaranteeing safe care and reliable results.

Endoscopy: an essential examination for gastrointestinal health

Upper Digestive Endoscopy is a minimally invasive examination that is essential for the diagnosis and treatment of various conditions of the upper digestive tract.

Using an endoscope – a thin, flexible tube with a camera at the end – it is possible to see inside the esophagus, stomach and duodenum. This test can identify problems such as gastritis, gastric ulcers, gastroesophageal reflux, esophagitis, polyps or tumors in the early stages.

Diagnosis by endoscopy is essential for investigating symptoms such as abdominal pain, persistent heartburn, difficulty swallowing, frequent nausea and other signs of gastrointestinal diseases. As well as being a safe and effective examination, it can also be used to perform biopsies and other therapeutic procedures, such as removing gastric and intestinal polyps and controlling bleeding.

Before the examination, it is important to strictly follow the endoscopy preparation guidelines, which usually include fasting and medication adjustments. This ensures clear images and accurate results, contributing to a more reliable diagnosis and effective treatment.

If you need an endoscopy, choose a specialized clinic with experienced professionals. At Instituto Medicina em Foco, Dr. Daniel Alvarenga is ready to offer safe, humanized care, prioritizing your health and well-being. Schedule your exam now!

Colonoscopy: prevention and diagnosis of intestinal diseases

This test is recommended for those with symptoms such as changes in bowel habits, bleeding in the stool or a family history of bowel diseases.

Dr. Daniel Alvarenga performs colonoscopy with a focus on prevention, diagnosis and patient comfort.
