Most of the standard lifestyle approaches to reflux are safe and often the first line of treatment during pregnancy: smaller, more frequent meals, avoiding lying down soon after eating, elevating the upper body at night, and identifying personal trigger foods. When lifestyle changes aren't enough, several medications are generally considered safe during pregnancy, though this should always be confirmed with an OB rather than assumed: calcium-based antacids are commonly recommended as a first option, and some H2 blockers and PPIs are used when needed under medical guidance, particularly later in pregnancy or for more persistent symptoms. What's not advisable is self-treating with medications or supplements not specifically cleared during pregnancy, since safety profiles differ from general use. Persistent or severe symptoms are worth discussing with an OB rather than managing entirely independently, both for comfort and to rule out other causes.
