Gastric Pain – Causes of Pains in the Stomach

Identifying abdominal pain as being isolated to the stomach is often difficult. The stomach is surrounded by many organs and structures that may be the cause of the pain.

However, the following features may be an indication of stomach related condition resulting in pain :

  • Pain that worsens or improves after eating or drinking
  • Pain that improves after taking antacids or worsens after drugs like NSAID’s and certain antibiotics, among others.
  • Pain due to stress (cardiac pain must be excluded – refer to Cardiac Pain vs Non Cardiac Pain)
  • Pain in the left or right upper quadrant of the abdomen but more specifically :
    • Pain under the left ribcage (left hypochondrium/hypochondriac region)
    • Upper middle abdominal pain (epigastrium/epigastric region)
    • Upper left flank (upper left lateral region)
    • Pain above the umbilicus (upper umbilical region)
    • Refer to the Stomach Location article for the approximate position of the stomach in the body.
