If you have acid reflux, there are some natural solutions that will help reduce some of your heartburn. If you begin using calcium supplements, you can start alleviating heartburn. The reason why calcium can reduce, or even prevent, heartburn is because it strengthens the lower esophageal sphincter (LES). Since calcium isn't an anti-acid, it won't provide fast relief. However, over time, it will provide long-term relief.
Pregnant women often experience acid reflux, especially in the last trimester of their pregnancy. This is caused when the baby grows large enough to limit the amount of space in the abdomen of the mother. You can try wearing looser clothing, avoiding certain foods that seem to set it off, or ask your doctor which medication is safe for the baby.
