Your thyroid is a small gland in your neck that makes hormones controlling your metabolism, energy, weight, temperature, heart rate, mood, and more. When it makes too little or too much hormone, you feel it all over your body.

A proper thyroid evaluation usually goes beyond TSH alone. Depending on your symptoms and history, this may include TSH, Free T4, Free T3, reverse T3 and thyroid antibodies, along with other labs that can affect how thyroid hormone is made, converted, and used in the body like insulin, cortisol, crp, ferritin, iodine, vitamin d, vitamin b12, and a GI Map.

Common signs include fatigue, weight gain, constipation, dry skin, swelling, feeling cold, hair thinning, and brain fog. They often come on slowly and get dismissed as stress or aging.

Unintentional weight loss, a rapid or irregular heartbeat, anxiety, tremor, feeling hot, diarrhea, and trouble sleeping. These can come on more quickly and should be evaluated.

Hashimoto’s is an autoimmune condition in which the immune system makes antibodies that attack the thyroid. Over time it can reduce thyroid function and cause hypothyroidism. It’s one of the most common causes of an underactive thyroid and can lead to other autoimmune conditions, hormone imbalances, and gut dysfunction if left untreated.

Hashimoto’s is an autoimmune condition, so the goal is not just to replace thyroid hormone, but to understand what may be driving the immune attack. While it is not typically considered “curable,” it can absolutely be put into remission, be treated, and often managed much more effectively when you address thyroid function, inflammation, gut health, nutrient deficiencies, and other root causes.

Graves’ is an autoimmune condition that drives the thyroid to overproduce hormones and is a common cause of hyperthyroidism. It needs proper testing and ongoing management as it can lead to other autoimmune conditions if left untreated.

Thyroid antibodies are markers that your immune system may be reacting against your thyroid. Elevated antibodies (TPO or Tg Ab) can suggest autoimmune thyroid disease, such as Hashimoto’s, and may help explain why thyroid symptoms are developing even before standard thyroid labs become clearly abnormal.

A “normal” TSH does not always mean your thyroid is functioning optimally. TSH is simply the signal from the brain telling the thyroid to produce hormone. Your thyroid makes mostly T4, but T4 must be converted into free T3 (FT3) — the active thyroid hormone that actually enters cells and helps drive energy, metabolism, mood, digestion, and more. If that conversion is impaired, or if thyroid hormone is not being used well at the tissue level, you can still have thyroid symptoms even when standard labs appear “normal.” Stress, inflammation, insulin resistance, low ferritin, nutrient deficiencies, hormone imbalance, and gut dysfunction can all play a role. That is why we run a more comprehensive thyroid work-up and look at the bigger picture, not just one number.

Because levothyroxine is T4, and your body still has to convert that into T3, the active thyroid hormone that actually works inside your cells. If that conversion is impaired by stress, inflammation, insulin resistance, gut dysfunction, or nutrient deficiencies, you may still feel hypothyroid even if your TSH looks “normal.”

Not always — it depends on the cause of your thyroid issue. Some patients do need long-term thyroid medication, especially if thyroid damage is significant or their thyroid gland has been removed, while others may also need a broader treatment plan that addresses inflammation, gut health, nutrient status, hormones, and metabolic health alongside medication.

That depends on the person and the underlying cause. Some people start noticing improvement of fatigue and brain fog within a few weeks, while others take longer, especially if there are additional issues like autoimmunity, nutrient deficiencies, gut dysfunction, inflammation, or hormone imbalance that also need to be addressed.

Yes… significantly. Chronic stress, gut dysbiosis, and systemic inflammation can interfere with thyroid hormone conversion, increase immune activation, and make it harder for hormones to work properly at the cellular level

Yes. Thyroid health plays a major role in reproductive hormones, ovulation, menstrual cycles, fertility, and pregnancy. It is especially important in pregnancy because the baby depends on the mother’s thyroid hormone until about 18 weeks gestation, which is why a deeper thyroid evaluation can matter so much for both conception and healthy pregnancy support. We offer thyroid optimization prior to and during pregnancy.

Thyroid nodules can form for several reasons, including thyroid tissue overgrowth, cysts, inflammation, autoimmune thyroid disease, or changes within the gland over time. Sometimes there is a clear reason, and sometimes they simply develop without one obvious cause.

It depends on the type of nodule. Some stay stable for years, some may grow slowly, and some may need treatment or biopsy depending on their size, appearance, symptoms, or function. The first step is understanding exactly what kind of nodule you have and whether it actually needs intervention. Then we determine what we can do to prevent further thyroid nodules from developing.

A fine needle aspiration (FNA) uses a thin needle to sample cells from a thyroid nodule to tell a benign condition from thyroid cancer. It’s done in-office without sedation, you won’t need a driver, and most patients have only about 3–5 minutes of downtime.
