Hiatal hernias occur when a portion of the stomach pushes up through a defect in the diaphragm. If the hiatal hernia becomes large, this condition causes food and acid to back up in esophagus, leading to acid reflux and heartburn, according to MayoClinic.com. Treatments for hiatal hernia target the symptoms associated with the condition. (See References 1 and 4)
Antacids
One treatment option for a hiatal hernia's symptoms of acid reflux and heartburn is over-the-counter antacids. Antacids work quickly to alleviate symptoms. However, antacids do not heal any damage to the esophagus reports MayoClinic.com. (See References 2, 3 and 4)
Histamine Type-2 Receptor Blockers
Histamine type-2 receptor blockers treat the symptoms of acid reflux and heartburn stemming from a hiatal hernia. Histamine type-2 receptor blockers work by decreasing stomach acid production. They are available over-the-counter or via prescription. (See References 2, 3 and 4)
Proton Pump Inhibitors
Proton pump inhibitors not only block acid production in the stomach to treat symptoms of acid reflux and heartburn, but also they allow the esophagus to heal. Proton pump inhibitors are available over-the-counter or via prescriptions. (See References 2, 3 and 4)
Lifestyle Changes
According to MedlinePlus, a website of the National Institutes of Health, eating smaller meals, losing weight and quitting smoking can alleviate symptoms associated with hiatal hernias. (See References 3)
Surgery
Surgery for a hiatal hernia may be necessary if a person fails to respond to medications to treat acid reflux and heartburn. Drugs.com notes that the goals of surgery include repairing stomach and esophagus, decreasing size of hiatal hernia or using the upper part of the stomach to provide support for the esophagus.
