Stomach pain with cramps and want to vomit consider dietary causes and disease causes. Dietary causes include eating irritating foods, overeating, etc. Disease causes include gastritis and duodenitis, peptic ulcer, and gastric masses. 1.

Such as stomach and duodenitis can have acid reflux, heartburn, stomach pain and other symptoms; such as peptic ulcer can have periodic stomach pain (stomach ulcer more than after meals stomach pain, duodenal ulcer more than fasting stomach pain); such as stomach mass can also have lethargy, fatigue, black stools and other symptoms.
