Consultation of a doctor gastroenterologist

At the Meliva Clinics Gastroenterology Center, experienced gastroenterologists provide consultations, perform diagnostic examinations, and treat patients with diseases of the digestive tract, including disorders of the esophagus, stomach, duodenum, small and large intestines, liver, gallbladder, and pancreas. Gastroenterologists prescribe the necessary laboratory tests to establish a diagnosis. In addition, endoscopic examinations and ultrasound scans are performed using modern diagnostic equipment.

Most common gastrointestinal diseases:

• Gastritis;
• Non-ulcer dyspepsia;
• Gastric and duodenal ulcers;
• Gastroesophageal reflux disease (GERD);
• Gallstones (cholelithiasis);
• Irritable bowel syndrome (IBS);
• Constipation;
• Hepatitis;
• Gastric and colorectal polyps, as well as cancer.

A consultation and examination by a gastroenterologist is recommended if you experience the following symptoms:

• Frequent nausea;
• Heartburn;
• Persistent dry cough;
• Abdominal bloating and pain;
• Constipation or diarrhea;
• Blood in the stool.

If you experience these or similar symptoms, do not delay seeking medical attention from a gastroenterologist. Accurate diagnostics and timely treatment can help prevent more serious gastrointestinal diseases.

Diagnostic examinations performed by gastroenterologists

At our clinics, gastroenterologists perform all necessary examinations to identify the cause of your symptoms as quickly as possible and determine the most effective treatment plan.

Colonoscopy is an examination of the large intestine performed for preventive screening, evaluation of symptoms, or follow-up after other procedures (such as polyp removal or colorectal cancer treatment). Patients may choose to undergo colonoscopy under sedation, ensuring greater comfort during the procedure. Preventive colonoscopy is recommended every 5-10 years for individuals over the age of 50. Colonoscopy is also performed in the presence of symptoms such as rectal bleeding, changes in bowel habits, or abdominal pain.

Rectoscopy is an examination of the rectum performed through the anus using a special instrument called a rectoscope. The procedure takes approximately 15-30 minutes. Bowel preparation is required beforehand. During the examination, the physician looks for polyps, signs of cancer or inflammation, and possible causes of bleeding.

Esophagogastroduodenoscopy (EGD) is an endoscopic examination of the lining of the esophagus, stomach, and duodenum. The procedure takes approximately 10-15 minutes and requires fasting for 6-8 hours and abstaining from drinking for 2-3 hours beforehand. During the examination, the throat is sprayed with a local anesthetic to minimize discomfort.

Abdominal ultrasound examination allows the physician to assess the internal organs, their movement, blood circulation, and structural characteristics using ultrasound technology. The examination is performed on an empty stomach.

The clinic also offers laboratory testing, including a complete blood count (CBC), urinalysis, blood biochemistry tests (AST, ALT, ALP, GGT, bilirubin, HBsAg, anti-HCV), and stool (coprological) analysis.

How should I prepare for a gastroenterological examination?

• Do not eat for at least 6 hours before the examination;
• Do not drink for at least 3 hours before the examination;
• Avoid smoking for 2 hours before the examination.
