Overview
Helicobacter pylori (H. pylori) is a spiral-shaped bacterium that infects the stomach lining of about half of the world's population — and is especially common in Saudi Arabia and the wider Middle East. Most people have no symptoms, but in others it causes chronic gastritis, peptic ulcers, and a small but real increase in the risk of stomach cancer. The good news: it can almost always be cured with a 10–14 day course of antibiotics combined with acid-suppressing medication.
Symptoms
Burning or gnawing pain in the upper abdomen (often worse on an empty stomach)
Bloating and frequent belching
Nausea or loss of appetite
Unintended weight loss
Iron-deficiency anemia (sometimes the only sign)
Indigestion despite acid-blocker medication
How It Spreads & Risk Factors
Spread mostly in childhood through saliva, contaminated food, or water
Crowded living conditions and shared utensils increase risk
A family member with confirmed infection
Living in or coming from a region with high prevalence (e.g. Saudi Arabia)
Poor sanitation in early life — the strongest risk factor
It is NOT caused by stress or spicy food
Testing & Treatment
Three reliable tests: urea breath test, stool antigen test, or biopsy during endoscopy
Stop proton-pump inhibitors (omeprazole, esomeprazole) for 2 weeks before testing — they cause false negatives
Stop antibiotics for at least 4 weeks before testing
Standard treatment: a combination of two antibiotics plus a proton-pump inhibitor for 14 days
Take ALL doses — incomplete treatment leads to resistance and treatment failure
Retest 4–8 weeks after finishing antibiotics to confirm eradication
If first treatment fails, a different antibiotic combination usually works
When to See a Doctor
See a doctor if you have persistent stomach pain, unexplained weight loss, vomiting blood, black tarry stools, or trouble swallowing — these can suggest a bleeding or complicated ulcer. Anyone in the family of a confirmed case, or anyone with iron-deficiency anemia, persistent indigestion, or a family history of stomach cancer, should be tested.

Stomach Ulcers (Peptic Ulcers)
Stomach ulcers are open sores that develop on the lining of the stomach or the upper part of the small intestine. They occur when the protective mucus layer is reduced, allowing digestive acids to eat away at the tissue. The two most common causes are H. pylori infection and long-term use of NSAIDs (like ibuprofen).
Heartburn & Acid Reflux
Heartburn is a burning feeling in your chest, behind the breastbone. It happens when stomach acid flows back up into your esophagus (food pipe). Occasional heartburn is common, but frequent heartburn (more than twice a week) may be a sign of GERD (gastroesophageal reflux disease).
Upper Endoscopy (EGD) Preparation
An upper endoscopy (also called EGD or gastroscopy) is a 10–15 minute procedure where a thin, flexible camera is passed through the mouth to examine the esophagus, stomach, and the first part of the small intestine (duodenum). It's used to investigate heartburn, swallowing problems, abdominal pain, anemia, or suspected ulcers — and it can take biopsies to test for H. pylori, celiac disease, or pre-cancerous changes (Barrett's esophagus). You'll be sedated through an IV and feel almost nothing.
