Conditions That Affect GERD or Are Similar to GERD in Symptoms

Peptic Ulcers
A peptic ulcer is a sore or lesion that forms in the lining of the stomach or duodenum. Ulcers in the stomach are called gastric or stomach ulcers, and those in the duodenum are called duodenal ulcers, and both are usually referred to as peptic ulcers.
Hiatal Hernia
A hernia occurs when an organ slips through the muscle wall that holds the organ in place. A hiatal hernia occurs when the upper part of the stomach pushes through an opening in the diaphragm, and up into the chest.
