My friend is pregnant and she heard somewhere that H. pylori can be dangerous and cause problems during pregnancy. How the bacteria contribute to an ulcer is unknown. They could interfere with the body's normal defenses against stomach acid, or they could produce a toxin that contributes to the formation of the ulcer. The treatment consists of one or more antibiotics and a drug to reduce or neutralize stomach acid. With treatment, peptic ulcers caused by this bacteria usually clear up in four to six days.
Symptoms can resolve in just a few days.
Pregnancy can aggravate gastrointestinal symptoms, although we didn't find any information about H. pylori and its relationship to pregnancy. Your friend should consult her obstetrician. Her doctor will need to evaluate the safety of treating her ulcers and giving antibiotics while she is pregnant. I had breast implants put in two years ago because my breasts were malformed after having three children. Breasts enlarge significantly as a pregnancy progresses.
