Causes of Ganglion Cyst
The causes of ganglion cyst formation are not fully understood, but several theories suggest they arise from joint or tendon irritation. Ganglion cysts seem to develop when synovial fluid escapes from a joint or tendon sheath and collects in a pouch or sac, forming a lump beneath the skin.
Joint and Tendon Overuse
Repetitive wrist or finger movement—especially in activities like typing, sewing, or using tools—may cause microtrauma to the joint lining
This repeated strain might lead to fluid leakage from the joint, resulting in a ganglion cyst
Manual labourers, musicians, and athletes are at higher risk
Joint or Tendon Injury
A previous injury or sprain may weaken the joint capsule or tendon sheath
The damaged area becomes a weak point, where fluid can accumulate and form a cyst
Even minor injuries can result in cyst formation months or years later
Underlying Joint Conditions
Individuals with osteoarthritis or other joint conditions may be more prone to developing ganglion cysts
These conditions lead to degeneration or irritation of joint tissues, increasing the likelihood of cyst formation
Age and Gender
Most common between ages 20 and 50
Occur more frequently in women, potentially due to hormonal factors or increased exposure to repetitive hand use
Unknown Causes
In some cases, ganglion cysts develop without any clear cause
This makes prevention difficult, although proper joint care and avoiding overuse may reduce the risk
Causes of Ganglion Cyst
Understanding the causes of ganglion cyst helps in recognising who is most at risk and why certain activities or conditions may contribute to their development.
