Helicobacter pylori (H. pylori) is one of the most common bacterial infections worldwide. Many people carry it without knowing, as it often doesn't cause symptoms at first. However, in some cases, it can lead to digestive discomfort and serious complications if left untreated.
Dr. Olfat Saif Al-Masih explains in this article the most common symptoms of H. pylori, when to see a doctor, and how to diagnose and treat the condition effectively.
H. pylori is a spiral-shaped bacterium that resides in the lining of the stomach. It affects the stomach's ability to regulate acid production and may lead to chronic gastritis, peptic ulcers, and—rarely—stomach cancer.
According to Dr. Olfat Saif Al-Masih, symptoms vary from person to person, but the most common include:
Stomach pain or burning, especially on an empty stomach
Bloating and persistent gas
Nausea or a sensation of wanting to vomit
Bad breath, despite oral hygiene
Loss of appetite or unexplained weight loss
Feeling full after small meals
Frequent burping
In more advanced cases, the following serious symptoms may appear:
Bloody or coffee-ground-like vomiting
Dark, tarry stools
Fatigue or dizziness from anemia due to internal bleeding
As noted by Dr. Olfat Saif Al-Masih, there are several accurate methods for diagnosis:
Urea breath test
Stool antigen test
Blood test
Upper endoscopy with biopsy (if necessary)
Treatment usually involves what’s called triple therapy, consisting of:
Two antibiotics
Proton pump inhibitors (PPIs) to reduce stomach acid
In some cases, a fourth medication may be added for resistance prevention
It’s essential to complete the full course of treatment to avoid recurrence or antibiotic resistance.
Avoid spicy and fried foods
Quit smoking and alcohol
Limit caffeine and carbonated drinks
Maintain proper hand hygiene
Do not share food or utensils
