Frozen shoulder (adhesive capsulitis) is a common, painful stiffening of the shoulder that usually eases over one to three years. Two questions come up a lot in the studio: is it linked to the new weight‑loss and diabetes injections, and can the gentle Bowen technique help? Here is an honest, evidence‑based answer.
What frozen shoulder actually is
The shoulder is wrapped in a sleeve of connective tissue called the capsule. In frozen shoulder this capsule becomes inflamed and then thickens and scars (fibrosis), so it tightens around the joint. The first sign is usually losing the ability to rotate the arm outward. It moves through three stages — freezing (painful), frozen (stiff) and thawing (recovery) — and is strongly associated with diabetes and thyroid disease.1
The weight‑loss injection question
Some patients on the newer weight‑loss and diabetes injections (known medically as GLP‑1 receptor agonists) ask whether the medication caused their frozen shoulder. The honest answer in 2026 is that there is an emerging, debated association — not a proven cause.
A large 2025 study found a modestly higher rate of frozen shoulder among people with diabetes using these medicines, and a 2026 cohort reported more tendon problems.23 But several other 2026 studies found no excess risk, and some even found better shoulder‑surgery outcomes.4 Crucially, these injections are taken by people who already carry a higher baseline risk of frozen shoulder — because of diabetes, obesity and thyroid disease — so the underlying condition, not the drug, may explain much of the link.
Where the Bowen technique fits
The Bowen technique is a gentle, light‑touch soft‑tissue therapy developed in Australia. For frozen shoulder the published evidence is limited — small, older pilot studies reported better movement and less pain, but there is no large trial.5 What Bowen does offer is that it is very gentle and safe, which makes it well suited to the painful “freezing” stage when firmer hands‑on work can be hard to tolerate. Many people find it relaxing and helpful as part of a broader plan.

FAQ
Can weight‑loss injections cause frozen shoulder?
There is an emerging, debated association in 2025–26 research, but no proven cause. People using these injections often already have a higher baseline risk from diabetes, obesity or thyroid disease. If new shoulder stiffness appears, talk to your prescribing doctor — do not stop the medication on your own.
Does the Bowen technique cure frozen shoulder?
No. Bowen is a gentle, complementary technique that some people find helpful for pain and movement, especially in the painful stage. It is offered alongside proper assessment and exercise, not as a cure or a replacement for medical care.
How long does frozen shoulder last?
Most cases gradually improve over about one to three years, even without treatment. Hands‑on treatment, gentle techniques and the right exercises can ease pain and help you regain movement sooner.
Should I stop my medication?
Never stop a prescribed medication on your own. If you are worried about shoulder stiffness, speak to the doctor who prescribed it — and book an assessment so your shoulder can be treated.
