I've "hyperacidity" from more than 10 years, my doctor always give me "omeprazole" is omeprazole save? Can this hyperacidity develop cancer?

Yes and yes: Omeprazole, a proton pump inhibitor, is relatively safe. There have been some recent reports in the news of possible increase in fractures due to weakening of the bones. The concern for hyperacidity is reflux up into the esophagus. This can lead to a barret's esophagitis (inflammation of the esophagus) that may be a precursor for esophageal cancer. ...Read more

Does taking omeprazole (40mg) every day decrease chances that Barrett's esophagus will turn into esophageal cancer? And does diet have an impact?

Low odd for a 25-yo: Once you have started out evaluation and treatment, it would be most logical to closely connect with your treating doctor about your response to the care so s/he may reassess your conditions and adjust the care options; if still in vain, upgrade the evaluation and care as needed, since there is no magic in medicine & life, if any, that is applying current available knowledge, skill, technology, . . ...Read more

Can fundic gland polyps turn into cancer? I have many in my stomach 3-6mm cause by long term use of Prilosec. Should I stop taking it.

Not clear: That is a good question. At present time we do not have evidence of this although some studies have suggested possible relationship with stomach cancer, but I would not stop sur to the finding of polyps. If you are taking for reflux why not consider an anti reflux procedure? ...Read more

GERD & cancer.: While reflux can cause cancer, I'd think you'd be way too young to worry about that right now. Happens in time, but you'd generally need to be much older, perhaps > 50 years old. ...Read more

I have acid reflux in which I'm taken 20mg omepeazole I'm I still at risk for cancer of the oesophageal?

Esophageal Cancer: Yes. If you have any ongoing acid into the esophagus there is risk. The goal is to find the cause of the acid reflux and to eliminate it; not just treat the stomach for low acid forever. Most people have to change their weight and their diets to get better control of these problems. ...Read more

Fundic gland polyps: These types of polyps in the fundus of the stomach are of no real concern. They do not increase the chances of cancer. They are not a reason to stop your Prilosec, if you need it. Your endoscopist will be able to follow up with you concerning them. Good luck. ...Read more

Is my daily frequent heartburn stomach cancer? When I take Prilosec the pain goes away but comes right back when I go off of it. 29 yr old male.

Need to evaluate: It is unlikely to be cancer, however, you likely have H pylori infection of the stomach and may need antibiotic treatment. It would be prudent to consult your doctor.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex, if you have sex. ...Read more

What are the chances of having throat or esophagal cancer by the age of 25? About 4.5 pack years. Had acid reflux but take prilosec now and its fine

Low risk at your age: Your risk of esophageal cancer is low at your age. I hope you are now an ex-smoker. However, if you have H. pylori infection as a cause of your reflux, you remain at risk for esophageal Ca. Take Mastic Gum (from a health food store) for your H. pylori and reflux. 1000 mg/day kills 99% of H. pylori in two weeks. ...Read more
