Functional Hashimoto's Doctor in Mamaroneck

If you’re dealing with all-day fatigue, weight changes, brain fog, or symptoms that don’t quite add up, Hashimoto’s disease may be the underlying cause.

Could Hashimoto's Be Causing Your Chronic Symptoms?

Hashimoto’s thyroiditis is one of the most common autoimmune conditions, yet it’s frequently misunderstood or under-treated. Standard care often focuses only on replacing thyroid hormone once levels fall outside of range. While medication can be important, it does not address the immune dysfunction driving the disease.

As a Hashimoto’s doctor in Mamaroneck, Dr. Giudice approaches thyroid disease differently. Instead of asking only how low your thyroid hormones are, functional medicine asks:

Why is the immune system attacking the thyroid?

What systems are contributing to inflammation?

What lifestyle, environmental, and metabolic factors are involved?

How can the body be supported to heal, regulate, and stabilize?

What Is Hashimoto's? Not Just Another Thyroid Condition

Hashimoto’s thyroiditis is an autoimmune disease. This means the immune system mistakenly identifies the thyroid gland as a threat and produces antibodies that attack thyroid tissue over time.

This is different from other thyroid conditions in several important ways:

Hashimoto's is immune-driven, not just a hormone imbalance

Symptoms often begin years before abnormal TSH levels appear

Thyroid function can fluctuate, especially in early stages

Damage is progressive if the immune response is not addressed

Medication alone does not stop the autoimmune attack

Hashimoto’s requires a broader, systems-based approach to care.

Recognize These Hashimoto's Symptoms?

Hashimoto’s can look different from person to person, but there are several hallmark symptoms. Many patients experience a combination of physical, cognitive, and emotional symptoms.

Chronic fatigue

Persistent exhaustion that doesn’t improve with rest. Many patients feel drained even after a full night of sleep.

Brain fog and poor concentration

Difficulty focusing, slowed thinking, memory lapses, or feeling mentally ‘cloudy.’

Weight gain or difficulty losing weight

Especially when lifestyle efforts don’t seem to work, due to slowed metabolism and hormone disruption.

Cold intolerance

Feeling unusually cold, having cold hands and feet, or sensitivity to cooler temperatures.

Hair thinning or hair loss

Particularly at the scalp or outer eyebrows, often accompanied by brittle hair or dry skin.

Mood changes

Anxiety, low mood, irritability, or depression, often tied to hormonal and inflammatory shifts.

Advanced thyroid and immune testing

Beyond TSH, including thyroid antibodies, free hormones, nutrient markers, inflammation, and metabolic indicators.

Gut health evaluation

Identifying food sensitivities, microbiome imbalances, or intestinal permeability that may be driving immune activation.

Targeted nutrition strategies

Anti-inflammatory, immune-supportive nutrition plans tailored to the individual.
