Comprehensive Guide to H. Pylori Infection: Symptoms, Diagnosis, and Treatments

H. pylori is a bacterium that colonizes the human stomach, often causing no immediate symptoms but potentially leading to serious conditions like ulcers and stomach cancer over time. Identified in 1982, it is a main cause of gastric ulcers, damaging the stomach lining and increasing vulnerability to bleeding and infection. Transmission mainly occurs through contaminated food, water, or utensils, especially in regions with poor sanitation, typically infecting children and remaining silent for years.

Signs of H. pylori Infection

Persistent stomach discomfort, burning, or dull ache, mainly on an empty stomach

Bloating, belching, nausea, vomiting, and unexplained weight reduction

Bleeding ulcers may cause dark stools, dizziness, fatigue, pale skin, or vomiting blood

Rarely, symptoms may mimic heartburn or indicate more severe issues like stomach cancer, with nausea, loss of appetite, early satiety, vomiting, and weight loss

Diagnostic Techniques

Medical history review and physical exam to detect tenderness or swelling

Blood and stool tests to identify infection markers

Urea breath test: consumes a urea solution, measuring exhaled gases for bacterial presence

Endoscopy: inserting a camera into the stomach to examine tissue samples

Barium swallow X-ray: drinking contrast to visualize ulcers and stomach lining

Available Treatments

Combination antibiotic therapy to eradicate H. pylori, typically lasting one to two weeks

Medications to lower stomach acid, promoting healing

Following the prescribed medication schedule is critical to avoid resistance

Post-treatment testing verifies complete eradication of the bacteria

Consult with healthcare providers for proper management of side effects and to ensure successful treatment outcomes.
