Your thyroid is a small gland that runs an enormous portion of your metabolism. When it's off, even a little, it shows up as fatigue, weight changes, mood shifts, brain fog, hair loss, or feeling cold or hot all the time. These symptoms get blamed on everything except the thyroid for years, when a simple lab test usually solves the mystery.

01

Conditions we manage

We diagnose and treat the full range of common thyroid conditions in primary care:

  • Hypothyroidism, underactive thyroid
  • Hyperthyroidism, overactive thyroid
  • Hashimoto's thyroiditis, autoimmune hypothyroidism
  • Graves' disease, autoimmune hyperthyroidism (co-managed with endocrinology)
  • Thyroid nodules and goiter (with imaging and biopsy referral when needed)
  • Postpartum thyroiditis
02

Symptoms to watch for

Thyroid symptoms vary by direction. Hypothyroidism slows you down; hyperthyroidism speeds you up.

  • Hypothyroid: fatigue, weight gain, cold intolerance, dry skin, hair thinning, constipation, depression, brain fog
  • Hyperthyroid: weight loss despite eating, racing heart, anxiety, heat intolerance, sweating, hand tremor, insomnia
  • Either: irregular periods, fertility issues, neck swelling
03

Testing and treatment

Most thyroid conditions are diagnosed with a simple blood panel. TSH first, then free T4, free T3, and antibodies if indicated. Treatment usually means daily medication and periodic re-checks to fine-tune the dose.

  • Levothyroxine for hypothyroidism (with attention to optimal, not just 'normal'. TSH)
  • Methimazole, beta blockers, or referral for definitive treatment of hyperthyroidism
  • Thyroid ultrasound and biopsy referral for nodules
  • Symptom-driven dose adjustments, not just lab-driven
Questions, Answered

Frequently asked questions.

Don’t see your question? Reach out and we’ll answer it directly.

How do I know if I have a thyroid problem?
The only way to know for sure is a blood test. If you have several persistent symptoms, fatigue, weight changes, hair or skin changes, mood shifts, ask for a TSH at your next visit.
How often do I need thyroid lab work?
After starting or adjusting medication, typically every 6–8 weeks until stable, then every 6–12 months.
Do I need to see an endocrinologist?
Most stable hypothyroidism and mild hyperthyroidism can be managed in primary care. We refer for nodules requiring biopsy, Graves' disease needing definitive treatment, and complex or unresponsive cases.
Can thyroid problems cause weight gain that won't budge?
Untreated hypothyroidism can absolutely cause weight gain, usually 5–15 pounds. Once treated, the weight typically comes off slowly. If the scale isn't moving despite normal labs, there's usually more going on, and we'll help you sort it out.
