Costs vary by country: in India the H. pylori stool antigen test typically costs ₹500–₹1,500; in the United States out‑of‑pocket prices commonly run about $50–$200 (can be higher at some labs). In health systems with public coverage it’s often provided at no direct charge. Final price depends on the laboratory, location and whether insurance or public care covers it.

Treatment of H. pylori is usually deferred until after pregnancy unless there is active peptic ulcer disease or severe symptoms. If therapy is needed, safer options commonly use amoxicillin with a proton pump inhibitor (for example, omeprazole). Clarithromycin, tetracyclines and metronidazole (especially in the first trimester) are typically avoided. Always discuss testing and treatment with your obstetrician.

A positive Helicobacter pylori stool antigen test means H. pylori bacteria are present in your gastrointestinal tract, indicating an active infection. This can cause gastritis, peptic ulcers, and, over time, raise gastric cancer risk. Treatment with appropriate antibiotics and acid suppression is usually recommended; recent antibiotics or proton‑pump inhibitors can affect test accuracy, so consult your clinician for treatment and follow‑up testing.

Treat confirmed H. pylori in children with a pediatrician-guided combination regimen: a proton-pump inhibitor plus two antibiotics (commonly amoxicillin with clarithromycin or metronidazole) for 10–14 days; bismuth-based quadruple therapy is used when resistance or failure occurs. Confirm eradication with a urea-breath or stool antigen test at least four weeks after antibiotics (and two weeks off PPIs). Adjust for age, allergies and local resistance.

If H. pylori infection is left untreated, it can cause chronic gastritis and peptic ulcers, which may lead to stomach pain, bleeding, perforation, or obstruction. Long-term infection raises the risk of iron-deficiency anemia, vitamin B12 deficiency and increases the likelihood of gastric cancer and MALT lymphoma. Untreated infection often causes persistent dyspepsia; appropriate testing and eradication therapy are recommended.

Helicobacter pylori infection is caused by exposure to the bacterium—typically via oral–oral or fecal–oral routes, contaminated food or water, or close contact—not by psychological stress. However, chronic stress can worsen stomach symptoms, increase acid production, impair immune response, and slow healing or symptom relief during treatment. Good hygiene, safe food practices, testing, and medical care are important if infection is suspected.
