What conditions can cause frozen shoulder?

Frozen shoulder or adhesive capsulitis can occur unexpectedly. There are some individuals who face a higher risk of developing the condition, particularly among mid-aged women. The reason why it develops is still not clearly understood. It is important to note that there are various conditions that have been distinguished to cause frozen shoulder.

Take note that the shoulder joint is comprised of the humerus, scapula and arm bone. The scapula has a shallow concave surface or glenoid. The rounded end of the humerus rests on the glenoid. Full range of motion of the shoulder is possible since there is a thin loose joint capsule that connects the humerus and glenoid.

Certain diseases

A frozen shoulder usually starts with the inflammation of the affected shoulder. Take note that the inflammatory process can cause severe pain. There is an extra development of the capsule coating or synovium. The inflammatory course can generate surplus fluid or scar tissue. Among individuals with the condition, the capsule will start to contract and eventually thicken as more collagen is created. As the capsule solidifies and contracts, the motion of the shoulder is significantly diminished.

There are ways in which a frozen shoulder usually occurs once an individual has sustained an injury. The most common way for the condition to develop is through an injury. The inflammation process will start in the shoulder. Another reason is the shoulder can be affected once a nearby joint such as the elbow or wrist is damaged. In case the shoulder is kept in a fixed position by using a sling, it can end up stiff. Always remember that the inflammation process will start in the shoulder. There are first aid measures that you can perform to provide relief to the symptoms of injuries. You can register for first aid training so that you know what to do in case these injuries occur.


Individuals who are suspected with adhesive capsulitis must be assessed for symptoms of diabetes. The symptoms include increased urination, increased thirst, unexplained weight loss and fatigue. It is important to note that frozen shoulder can occur among individuals who are diabetic. The reason for this is not yet fully understood.

Heart and the lungs

Frozen shoulder can develop after the individual suffers from a heart or lung condition. The condition can occur after a heart surgery as well as after a heart attack. Individuals who suffered a stroke are at risk for adhesive capsulitis from the heart connection as well as from the loss of motion. Those who have tuberculosis also face a higher risk for developing frozen shoulder.

Other diseases that can cause frozen shoulder

There are also thyroid diseases due to either low or high level of thyroid hormone that has been linked with adhesive capsulitis. Graves’s diseases and Hashimoto’s disease are thyroid diseases that can lead to frozen shoulder among younger individuals.

Unexplained weight loss or gain is a characteristic of thyroid diseases. When it comes to autoimmune diseases, the body produces antibodies that attack the organs. Examples of autoimmune diseases include Grave’s disease, juvenile diabetes and Hashimoto’s disease. Always remember that frozen shoulder is linked with these conditions. Additionally, Parkinson’s disease is also linked with adhesive capsulitis.
