Using the navel as a reference point, the abdomen is divided into four positions: epigastric (above the navel), hypogastric (below the navel), left iliac fossa (to the left of the navel), and right iliac fossa (to the right of the navel). When experiencing lower abdominal pain (hypogastric pain), depending on the severity of the pain and symptoms, it can be a mild illness or an emergency, so when experiencing severe pain in the lower abdomen, it should never be ignored or taken lightly.
