Yes, hormonal changes may be linked to frozen shoulder, especially around perimenopause and menopause, when estrogen levels change. However, research has not proved that these changes directly cause the condition, and hormone therapy has not been shown to prevent or reliably treat it. Thyroid disorders are also associated with a higher risk. Shoulder pain and stiffness still need assessment, because several conditions can cause similar symptoms.
Frozen shoulder, also called adhesive capsulitis, causes pain and stiffness that gradually restrict shoulder movement. It is particularly common in adults between 40 and 60 years of age and affects women more often than men. Because these years often overlap with the menopausal transition, researchers are investigating whether changes in estrogen and other hormones contribute to the condition. The connection is plausible, but important questions remain unanswered.
How might hormonal changes be related to frozen shoulder?
The shoulder joint is surrounded by a layer of connective tissue called the joint capsule. In frozen shoulder, this tissue becomes inflamed, thickened, and tight, making it harder to move the arm. The exact reasons these changes develop are not fully understood.
Estrogen is a hormone involved in several processes throughout the body, including those affecting connective tissues. Researchers have proposed that changes in estrogen during the menopausal transition may influence joint tissues and their response to inflammation. These ideas provide a possible explanation for the overlap between menopause and frozen shoulder, but they do not establish that falling estrogen levels cause the condition in an individual.
According to Cleveland Clinic, frozen shoulder involves inflammation and tightening of the capsule surrounding the shoulder joint. Its development is not fully understood, and several other factors are associated with an increased risk.
Is frozen shoulder more common during perimenopause and menopause?
Frozen shoulder is more common in middle-aged adults, particularly women. Perimenopause, the transition leading up to menopause, and menopause itself can involve substantial changes in hormone levels. This timing has led researchers to investigate whether hormonal changes help explain the condition's age and sex patterns.
However, the overlap does not mean that menopause necessarily triggers frozen shoulder. Many people experience menopause without developing the condition, while frozen shoulder can occur in people who are not going through menopause. Age, reduced shoulder movement after an injury or operation, and certain medical conditions also matter.
A pilot study published in 2026 examined medical records for 1,952 postmenopausal women aged 40 to 60. Frozen shoulder was recorded in 7.65% of women who were not using hormone therapy and 3.95% of those using it. Although the difference suggested a possible association, it was not statistically significant. The study therefore did not establish that hormone therapy reduces the risk of frozen shoulder. The findings are available in the study indexed by PubMed.
Can thyroid hormone problems increase the risk?
Thyroid conditions are another important part of the relationship between hormones and frozen shoulder. Both an underactive thyroid, known as hypothyroidism, and an overactive thyroid, known as hyperthyroidism, have been associated with an increased risk of developing frozen shoulder.
The reason for these associations is not fully established. Having a thyroid condition does not mean a person will develop frozen shoulder, and shoulder stiffness alone cannot establish that thyroid function is abnormal.
According to Mayo Clinic, frozen shoulder is more common in people with thyroid conditions and diabetes. If you already have a thyroid disorder and develop persistent shoulder pain or restricted movement, tell your healthcare professional about both issues. They can decide whether your existing medical history, current treatment, or additional assessment is relevant.
Can hormone replacement therapy help frozen shoulder?
Hormone replacement therapy (HRT), also called menopausal hormone therapy, is used to manage selected symptoms associated with menopause. It has attracted research interest because estrogen changes may be related to frozen shoulder. However, the available evidence does not establish HRT as a prevention or treatment for this shoulder condition.
The 2026 pilot study described above did not find a statistically significant difference in frozen shoulder rates between postmenopausal women who used hormone therapy and those who did not. The study was observational, meaning it examined existing medical records rather than assigning participants to treatment groups. Larger prospective studies are needed to clarify whether hormone therapy has any meaningful effect.
Research is continuing. The University of California, San Francisco frozen shoulder clinical trial is investigating whether adding hormone replacement therapy to standard treatment affects frozen shoulder symptoms in women experiencing age-related menstrual changes. The existence of this trial indicates that the question remains under investigation; it does not establish that HRT is effective.
Hormone therapy should not be started, stopped, or adjusted solely to manage shoulder pain without medical guidance. Decisions about menopausal hormone treatment depend on the person's symptoms, medical history, potential benefits, and risks. If you are already considering HRT for menopause-related symptoms, discuss the shoulder problem with the clinician helping you make that decision.
How can you tell whether hormonal changes are involved?
There is currently no single symptom, blood test, or hormone measurement that can confirm that hormonal changes are responsible for frozen shoulder. A clinician usually considers the shoulder symptoms, how they developed, the person's medical history, and a physical examination.
Frozen shoulder commonly causes gradually increasing pain and stiffness. Reaching overhead, reaching behind the back, getting dressed, or moving the arm outward may become difficult. Pain can also disturb sleep. These experiences can occur with other shoulder conditions, including arthritis, rotator cuff problems, and inflammation affecting nearby tendons.
When appropriate, a clinician may assess a person's history of menopause or thyroid disease alongside the shoulder examination. Imaging, such as an X-ray, may be used to investigate other possible explanations for the symptoms. Hormone testing is not automatically required simply because someone has shoulder pain during menopause.
What should you do if shoulder stiffness develops during menopause?
Do not assume that shoulder pain is an unavoidable part of aging or menopause. Persistent stiffness deserves assessment, particularly when it interferes with sleep, work, dressing, personal care, or other daily activities. The National Health Service (NHS) advises seeing a general practitioner for shoulder pain and stiffness that does not go away or pain that makes moving the arm difficult.
If frozen shoulder is diagnosed, treatment generally focuses on reducing pain and gradually restoring movement. Depending on the person's needs, this may include:
- Gentle shoulder movements and exercises recommended by a healthcare professional.
- Physiotherapy to help maintain or gradually improve the shoulder's range of motion.
- Appropriate pain-relief medicines or, in selected cases, a corticosteroid injection.
- Further assessment or treatment when pain and restricted movement persist despite initial care.
Exercises should be matched to the person's pain and mobility. Forcing a stiff shoulder through painful movements or beginning strenuous stretching without guidance may aggravate symptoms. A clinician or physiotherapist can recommend an appropriate approach.
Frozen shoulder often improves over time, although recovery may take months or longer. Addressing the shoulder problem directly remains important even when hormonal changes may be part of the broader picture.
What is the main takeaway about hormones and frozen shoulder?
Hormonal changes, particularly those surrounding menopause, may be associated with frozen shoulder, but a direct cause-and-effect relationship has not been established. Thyroid disorders are also associated with increased risk, although their presence does not guarantee that the condition will develop.
Current evidence does not support using hormone replacement therapy specifically to prevent or treat frozen shoulder. If shoulder pain and stiffness begin during a hormonal transition, the most useful next step is to have the shoulder assessed and discuss any relevant menopause or thyroid history with a healthcare professional.
