Each person with Down's syndrome is affected differently, but most share a number of physical characteristics and developmental problems.
People with Down's syndrome often have certain physical characteristics. Not everyone will have all of them, but they may include:
- Reduced muscle tone that results in floppiness (hypotonia).
- A small nose and flat nasal bridge.
- A small mouth with a protruding tongue.
- Eyes that slant upwards and outwards.
- A flat back of the head.
- A big space between the first and second toe (sandal gap).
- Broad hands with short fingers.
- Their palm may have only one crease across it (single transverse palmar crease).
- Below-average weight and length at birth.
