Diseases of the gastrointestinal tract (gastroenterology)

Inflammatory bowel disease in adults

Inflammatory bowel diseases, including Crohn's disease and ulcerative colitis, are relapsing diseases with periods of remission and are characterized by chronic inflammation of various parts of the gastrointestinal tract, leading to diarrhea and abdominal pain.

Excessive bacterial growth in the small intestine

Small intestinal bacterial overgrowth may be due to anatomical changes in the intestine or gastrointestinal motility disorders, as well as gastric secretion insufficiency. These disorders may lead to vitamin deficiencies, fat malabsorption, and nutritional deficiencies.

Traveler's diarrhea

Traveler's diarrhea is a gastroenteritis that is usually caused by bacteria native to local water bodies. Symptoms of traveler's diarrhea include vomiting and diarrhea. Diagnosis is primarily clinical. Treatment for traveler's diarrhea includes ciprofloxacin, loperamide, and fluid replacement.

Medicated gastroenteritis.

Many drugs cause nausea, vomiting, diarrhea, drug-induced gastroenteritis, which are considered side effects. It is necessary to collect a detailed anamnesis regarding the use of the drug.

Gastroenteritis

Gastroenteritis is an inflammation of the mucous membrane of the stomach, small intestine and large intestine. In most cases, it is an infectious disease, although gastroenteritis can develop after taking medications and chemical toxic substances (e.g. metals, industrial substances).

Acute pancreatitis in adults

Acute pancreatitis is an inflammation of the pancreas (and sometimes surrounding tissues) caused by the release of activated pancreatic enzymes. The main triggers of the disease are biliary tract diseases and chronic alcohol abuse.

Bezoar

A bezoar is a solid mass of partially digested and undigested material that cannot be evacuated from the stomach. It is often seen in patients with impaired gastric emptying, which may be caused by gastric surgery.

Peptic ulcer

A peptic ulcer is a peptic defect in an area of the gastrointestinal mucosa, usually in the stomach (gastric ulcer) or the first part of the duodenum (duodenal ulcer), that penetrates into the muscular layer.

Atrophic gastritis

Autoimmune metaplastic atrophic gastritis is a hereditary autoimmune disease that is based on damage to parietal cells, leading to hypochlorhydria and decreased production of intrinsic factor.

Menetrier's disease

Menetrier's disease is a rare idiopathic syndrome occurring in adults aged 30-60 years and more common in men. The syndrome manifests as marked thickening of the gastric folds in the body of the stomach, but not the antrum.
