ÚLCERA GÁSTRICA o DUODENAL: Síntomas, Causas y Tratamiento

Understanding Gastric Ulcers and Their Treatments

Introduction to Gastric Ulcers

• Dr. Alberto Sanagustín introduces the topic of gastric ulcers, explaining that they can occur in the stomach or duodenum, which is the first part of the small intestine.

• He describes ulcers as wounds in the internal lining of these organs, leading to unpleasant symptoms such as abdominal pain and acidity.

Symptoms and Complications

• Common symptoms include nausea, vomiting, gastrointestinal bleeding, stomach perforations, and potential scarring that may cause obstructions.

• Diagnosis typically involves gastroscopy, where a tube with a camera is inserted to detect lesions or ulcers; biopsies may also be taken for further analysis.

Causes of Gastric Ulcers

• The primary cause of ulcers is an imbalance between stomach acid production and mucosal protection. Excess acid or damaged mucosa can lead to ulcer development.

• In industrialized countries, up to 10% of people may experience an ulcer during their lifetime; duodenal ulcers are often diagnosed around age 40 while stomach ulcers are more common at age 50.

Helicobacter Pylori Infection

• A significant cause of gastric ulcers is infection by Helicobacter pylori bacteria, which may be transmitted through food, water, or close contact like kissing.

• While many carry this bacterium without symptoms, genetic and environmental factors can trigger ulcer formation in susceptible individuals.

Medications Contributing to Ulcer Development

• Non-steroidal anti-inflammatory drugs (NSAIDs), including aspirin and ibuprofen, are known contributors to gastric issues and ulcer formation due to their effect on mucosal integrity.

• Other medications like corticosteroids and selective serotonin reuptake inhibitors (SSRIs), when combined with NSAIDs, can exacerbate risks for developing ulcers.

Additional Risk Factors

• Lifestyle factors such as tobacco use and alcohol consumption can increase the likelihood of mucosal injury and enhance hydrochloric acid production.

• Certain foods—especially spicy or heavy meals—may worsen existing conditions but do not directly cause ulcers.

Rare Causes: Zolinger-Ellison Syndrome

Understanding Gastric Ulcers and Their Treatment

Causes of Gastric Ulcers

• Excessive production of gastrin can lead to repeated refractory ulcers, with Crohn's disease being a potential contributor to intestinal ulcers affecting the duodenum and stomach.

• Gastric cancer may also cause ulceration; thus, gastroscopy and biopsies are recommended for individuals over 50 or when symptoms suggest complications.

Symptoms Indicating Serious Conditions

• Constitutional syndrome symptoms such as fatigue, anorexia, weight loss, and loss of appetite should raise concerns about gastric cancer in patients over 50.

Treatment Options for Ulcers

• Effective treatments target the underlying causes; if H. pylori bacteria are present, antibiotic treatment is necessary. Anti-inflammatory drugs should be reduced or eliminated if they contribute to ulcer formation.

• Treatments that reduce stomach acidity help regenerate the mucosa; antibiotics like amoxicillin and clarithromycin are commonly used based on geographic resistance patterns.

Medications Used in Treatment

• Proton pump inhibitors (PPIs), such as omeprazole, pantoprazole, and lansoprazole, significantly reduce symptoms by blocking acid production. Long-term use may have side effects but is generally safe if not prolonged.

• Antacids provide symptomatic relief by neutralizing stomach acid but do not treat ulcers directly. H2 receptor antagonists like cimetidine and famotidine were previously used but are now less common.

Lifestyle Changes and Natural Remedies

• Quitting smoking and reducing alcohol intake can enhance healing; while spicy foods may aggravate symptoms, they do not cause ulcers.

• Dietary adjustments should focus on avoiding large meals or specific foods that trigger discomfort; however, these changes alone will not cure an ulcer.

Understanding Ulcers and Their Complications

Importance of Medical Attention for Ulcers

• The discussion emphasizes that while some treatments may improve symptoms, they do not address the ulcer itself.

• It is crucial to be cautious as ulcers can lead to severe complications such as hemorrhage, perforation, or abnormal scarring.

• These complications can result in stenosis, which refers to the narrowing of passages in the body, leading to further health issues.
