In macromastia, the physical, functional, and psychosocial impacts it causes are more significant issues than the size of the breasts themselves.
Increased breast weight can affect posture, motor function, and skin health, potentially causing difficulties in various aspects of daily life. This page outlines the typical symptoms associated with macromastia and their impact on quality of life (QOL).

Common physical symptoms associated with macromastia include chronic pain such as shoulder stiffness, neck pain, back pain, and lower back pain.
The weight of the breasts pulling forward disrupts the balance of the torso, causing the body to unconsciously attempt to correct posture. This results in sustained strain on muscles and joints.
Additionally, skin compression and indentation from shoulder straps, as well as increased fatigue from prolonged standing or walking, may also be observed.
