Terrible Indigestion
Ulcers can cause a variety of gastro intestinal problems including uncomfortable indigestion and gas pain. This commonly means lots of burps and hiccups after a meal.
Nausea
The imbalance of digestive juices that comes along with an ulcer causes the sufferer to feel nausea. This nausea most commonly occurs first thing in the morning, when your stomach is empty, and can be anywhere from mild to severe.
