Study Notes

Body Habitus Overview

Body habitus refers to classifications of body structures, including the size, shape, and position of organs.
Four main body habitus types: hypersthenic, sthenic, hyposthenic, and asthenic.

Hypersthenic Habitus

Represents approximately 5% of the population.
Characterized by a massive build with a broad, thick, and short thorax.
The ribs appear almost horizontal upon deep inspiration.
High diaphragm leads to a longer abdominal cavity.
Gallbladder and stomach are positioned laterally from the midline.
The transverse axis of the stomach is longer than the longitudinal.
Colon sits high and extends around the entire body cavity.
Films must be turned crosswise to capture all critical anatomy.

Sthenic Habitus

Comprises about 50% of the population.
Organs are located in standard "textbook" positions.
Gallbladder is positioned 2-3 inches away from the midline and 4-5 inches above the iliac crest.

Hyposthenic Habitus

Accounts for roughly 35% of the population.
Considered a modified asthenic type but leans toward "textbook" arrangement.
Gallbladder typically lies 1-2 inches away from the midline and 2-3 inches above the iliac crest.

Asthenic Habitus

Found in about 10% of individuals.
Characterized by a narrow and shallow thorax with sharply sloped ribs.
Apices of the lungs are broader than the bases.
Heart appears long and narrow in this body type.
Diaphragm is naturally low in position, and stomach appears vertical, narrow, resting low in the abdominal cavity, and looks tortuous.
Seemingly constant peristaltic action contributes to the tortuosity of the stomach.
Gallbladder is vertical, close to the midline, often at or above the iliac crest.
Colon appears to fold in upon itself and occupies a median position in the abdominal cavity.

Summary of Habitus Sizes

Body habitus ranks from largest to smallest: hypersthenic, sthenic, hyposthenic, and asthenic.
