    The pancreas releases the digestive juices (enzymes) needed to take nutrients out of our food and put them into our body. To do this, the pancreas has a complicated system of ducts that collect and transport digestive enzymes. Through these ducts, the enzymes are led to the duodenum, the upper part of the small intestine. The nutrients of the food are then absorbed in the small intestine.

    The proton pump inhibitor (PPI) you've been using for acid reflux may contribute to bone loss. There's evidence that PPIs weaken bones, partly by interfering with calcium absorption. Usually, this only increases fracture risk at high doses or over a long period of time.

    Talk with your doc about swapping your PPI for an H2 antagonist ( “H” is for histamine) such as Zantac, Pepcid or Tagamet. There's evidence that H2 antagonists are not associated with fractures and may even protect bones.

    Talk with your doctor or pharmacist before taking the antibiotic methenamine with an Alka-Seltzer product. The brand name Alka-Seltzer refers to a variety of products that treat an array of conditions, and some of them may interact with methenamine. If your doctor says it's okay for you to combine methenamine with the indigestion medicine Alka-Seltzer Heartburn (sodium bicarbonate), be sure to take them at least two hours apart to minimize your chance of complications.

    The brand name Alka-Seltzer refers to a family of products, each of which has its own active ingredients. The product designed for heartburn, the condition that's probably most commonly associated with the brand, is called Alka-Seltzer Heartburn (sodium bicarbonate). Alka-Seltzer Heartburn has two primary active ingredients: anhydrous citric acid and sodium bicarbonate. It also contains several inactive ingredients, including acesulfame potassium, aspartame and flavorings.
