Dupuytren’s and Hormones: The Endocrine Link to Fibrosis
Introduction
Hormones orchestrate nearly every biological process—growth, energy use, and tissue repair. Researchers now recognize that hormonal imbalances can also influence fibrotic diseases like Dupuytren’s contracture. By shaping fibroblast behavior, hormones such as thyroid hormone, testosterone, and estrogen can either stimulate or suppress the buildup of collagen in connective tissue.
For patients, this means that endocrine health—long considered separate from hand health—may be an overlooked piece of the Dupuytren’s puzzle.
Definition / Mechanisms
The endocrine system communicates through hormones, chemical messengers that tell cells when to grow, divide, or repair. In connective tissue, these signals keep collagen turnover balanced: old fibers are broken down as new ones form. When hormone levels fall out of range, fibroblasts can stay “switched on,” continuing to produce collagen even after an injury has healed. This overactivity creates fibrosis — the stiff, scar-like tissue seen in Dupuytren’s.
Thyroid, sex, and stress hormones all influence fibroblast metabolism and the expression of fibrosis-related genes such as TGF-β and collagen type I. When these hormonal signals are distorted by disease or age, they can tip the balance toward pathologic collagen accumulation.
Thyroid and Dupuytren’s
Thyroid hormones (T3 and T4) govern metabolism and tissue renewal. In hypothyroidism, metabolic rate slows, reducing collagen degradation and encouraging buildup. Several epidemiologic studies show higher rates of Dupuytren’s and related fibroses in patients with low thyroid function. Low T3 levels may also impair mitochondrial energy production, making fibroblasts more susceptible to oxidative stress【internal link → Article 50 Oxidative Stress and Dupuytren’s】.
Balancing thyroid function—through medical treatment or nutritional support for iodine, selenium, and zinc—may improve tissue turnover and reduce recurrence after surgery.
Sex Hormones and Fibrosis
Dupuytren’s occurs predominantly in men, suggesting a role for testosterone. Androgen receptors are found on fibroblasts, and lab studies show testosterone can enhance collagen synthesis and myofibroblast formation. Conversely, estrogen appears protective: it down-regulates fibrotic genes and boosts antioxidant enzyme activity, helping explain why women tend to develop Dupuytren’s later and less severely.
Post-menopausal decline in estrogen, however, may remove this protective buffer, raising risk for fibrosis in both hands and other tissues.
Research Evidence
Comprehensive reviews in Endocrine Reviews and related journals have found higher incidence of Dupuytren’s among people with hormonal and metabolic disorders【research link → https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3774433/】. Cell culture studies demonstrate that adding testosterone to fibroblast cultures increases collagen output, while estrogen reduces it. Other data link hypothyroidism to slower collagen clearance and reduced matrix remodeling.
Although hormones are unlikely to be the sole cause, they can “tip the scales” in genetically susceptible individuals. This research supports a multisystem view of Dupuytren’s rather than a localized hand disease.
Endocrine Disorders and Risk
Endocrine conditions frequently overlap with Dupuytren’s: diabetes, thyroid disease, and metabolic syndrome all create a pro-fibrotic environment【internal link → Article 52 Metabolic Syndrome and Dupuytren’s】【external link → https://www.mayoclinic.org】. High insulin and inflammatory cytokines stimulate fibroblasts, while low thyroid and sex hormone levels weaken tissue repair. Stress hormones like cortisol add another layer: chronically elevated levels suppress healing yet prolong inflammation, creating ideal conditions for fibrosis.
Patient Considerations / Lifestyle Support
Patients should recognize that hormonal health affects more than energy or mood—it also influences how connective tissue heals. Steps that support balanced endocrine function include:
Monitor thyroid levels (TSH, Free T3/T4) and treat deficiency early.
Support adrenal balance through adequate sleep and stress management.
Maintain healthy weight and insulin sensitivity with exercise and a low-glycemic diet.
Consider micronutrients like selenium, zinc, and vitamin D that aid hormone synthesis.
Consult a qualified practitioner before using hormone replacement or supplements.
Such measures not only optimize general health but may also slow Dupuytren’s progression and improve outcomes after treatment.
What the Science Says
The connection between hormones and fibrosis is reinforced by multiple organ studies. Low thyroid levels and high testosterone both enhance fibrotic signaling through TGF-β activation, while estrogen and thyroid replacement suppress it. Researchers are exploring hormone-modulating drugs and natural compounds that could restore balance in fibroblast signaling pathways.

Why It Matters if You Have Dupuytren’s
If you live with Dupuytren’s, unrecognized hormonal imbalance can quietly accelerate disease progression. Addressing thyroid or sex-hormone issues alongside hand treatment offers a more holistic path to healing. Ask your doctor about thyroid testing and discuss how hormone balance might influence fibrosis risk.
Viewing Dupuytren’s as part of a broader systemic pattern empowers patients to treat root causes rather than symptoms alone.
Key Takeaways
Hormones affect fibroblasts. Imbalances can stimulate excess collagen and fibrosis.
Thyroid and sex hormones are key. Low thyroid and high testosterone increase risk; estrogen may protect.
Endocrine disorders overlap. Diabetes and metabolic syndrome raise Dupuytren’s likelihood.
Testing matters. Thyroid and hormone panels guide personalized care.
Whole-body focus. Balancing hormones supports healing and prevents recurrence.
