Hormone Imbalance

Hormones coordinate nearly every physiological process in the body, from energy metabolism and sleep cycles to mood regulation and immune function. The endocrine system is vulnerable to viral disruption, and SARS-CoV-2 has been shown to affect multiple hormonal axes. ACE2 receptors, the entry point for the virus, are expressed in the thyroid, adrenal glands, pituitary, and reproductive organs. This means the virus can directly impair hormone-producing tissues, and the resulting imbalances may persist long after the acute infection clears.

Thyroid dysfunction is among the most commonly reported hormonal changes after COVID. Subacute thyroiditis, autoimmune thyroid flares, and shifts in T3/T4 conversion have all been documented. The hypothalamic-pituitary-adrenal (HPA) axis, which governs the stress response and cortisol production, can also become dysregulated. Some Long COVID patients show blunted cortisol patterns that resemble adrenal insufficiency, contributing to fatigue, orthostatic intolerance, and poor stress recovery. Sex hormones are affected as well. Disruptions to testosterone, estrogen, and progesterone have been reported in both men and women, with symptoms ranging from menstrual irregularities and low libido to worsened fatigue and mood changes.

Addressing hormonal imbalances in Long COVID requires careful evaluation rather than blanket supplementation. Dr. Groysman orders comprehensive hormonal panels for patients whose symptom profiles suggest endocrine involvement. Treatment may include thyroid optimization, adrenal support through adaptogenic compounds and lifestyle modifications, or targeted hormone replacement when lab values and clinical presentation warrant it. Because hormonal systems are interconnected, correcting one axis often produces improvements across several symptom domains. This makes endocrine evaluation an important and sometimes overlooked component of comprehensive Long COVID care.
