Functional Medicine Doctor in Southport, CT | Dr. Michael Duben

Functional Medicine Doctor in Southport, CT

If you live in Southport and you’re still feeling off despite “normal” labs — the answer may be closer than you think. As a board-certified endocrinologist with over 20 years of clinical experience, I offer Southport patients immediate access to specialist-level, root-cause care without a long drive.

My practice, Restore Health LLC, is located at 501 Kings Highway East in Fairfield, CT — less than 5 minutes from Southport village. There is no closer board-certified endocrinologist offering functional medicine in Fairfield County.


Why Southport Patients Come to Me

You have a specialist in your backyard. Most Southport residents don’t realize that a board-certified endocrinologist with fellowship training at Mount Sinai and Montefiore/Albert Einstein is practically around the corner.

I trained under Dr. Norman Fleischer — one of the preeminent endocrinologists in the country — and Dr. Martin Surks, a world-renowned thyroid expert. That level of training, combined with a root-cause functional medicine approach, is what sets my practice apart from the wellness clinics and telehealth platforms competing for your attention.

What I investigate that others miss:

  • Thyroid function beyond TSH — Free T3, Free T4, reverse T3, and thyroid antibodies
  • Hashimoto’s thyroiditis — the autoimmune root cause behind most hypothyroidism
  • Mitochondrial function and energy production — cellular-level disruptions that explain fatigue conventional labs never catch
  • Gut microbiome assessment when digestive, immune, or metabolic patterns suggest an underlying connection
  • Toxicology and environmental exposure testing — heavy metals, endocrine disruptors, and other factors that silently drive hormone dysfunction
  • Hormone optimization — testosterone, estrogen, and the full picture
  • Insulin resistance and cardiometabolic markers that predict problems years before diagnosis

Specialist Care Without the Drive

Southport residents have a significant advantage — my office is less than 5 minutes away. Your initial consultation is 90 minutes. I review your full history, prior labs, lifestyle, and symptoms with a thoroughness that a rushed 10-minute appointment simply cannot match.

Common reasons Southport patients book with me:

  • Diagnosed with hypothyroidism but still feel unwell on levothyroxine
  • Told labs are normal but symptoms say otherwise
  • Suspected Hashimoto’s with no clear guidance from current doctor
  • Unexplained fatigue, brain fog, weight gain, or hair loss
  • Want a board-certified endocrinologist, not a health coach or telehealth generalist

Board-Certified Endocrinology. Cash-Pay. Right Next Door.

Restore Health LLC is a cash-pay, concierge practice. No insurance means no rushed appointments and no treatment decisions driven by what a payer will cover. You get my full attention — and a level of thoroughness that insurance-based medicine rarely allows.

For follow-up flexibility, HIPAA-compliant telemedicine is available after your initial in-office visit.
