• The head looks more inclined forward than the rest of the body.
• When bending, the height of the upper back looks abnormal.
• The hamstring muscles (muscles behind the thigh) feel tight.
• Back pain and stiffness.

Causes of kyphosis, among others: wrong posture; abnormalities in the development of the spine before puberty; and developmental abnormalities of the spine while still in the womb.
