Protuberant-a protuberant (bulging, stretched) abdomen is caused by conditions such as pregnancy, obesity, or ascites.
a rounded abdomen is not as stretched or bulging as a protuberant abdomen and is seen most often in individuals who are overweight.
hernias can occur over a specific area such as the umbilicus, inguinal areas, or around scars, but not across the entire abdomen.
a scaphoid abdomen is boatlike in appearance and is seen in very thin individuals or those with decreased abdominal musculature.
