Optimizing Your Thyroid: A Functional Medicine Approach to Thyroid Health
An estimated 20 million Americans have a thyroid condition, yet many go undiagnosed or are ineffectively treated. A comprehensive approach requires looking beyond standard lab values to the root cause of the imbalance. At SouthPark Functional Medicine, Dr. Mahtani creates a strategic path toward resolving the underlying drivers of thyroid dysfunction and restoring your metabolic health.
What Are Thyroid Issues?
The thyroid is a butterfly-shaped gland located in the front of the neck. This gland plays a significant role in regulating various bodily functions by producing hormones controlling metabolism, energy levels, and mood. There are two common thyroid conditions: hypothyroidism and hyperthyroidism.
Hypothyroidism occurs when the thyroid gland doesn’t produce enough hormones, particularly thyroxine (T4) and triiodothyronine (T3). It can be caused by autoimmune diseases like Hashimoto’s thyroiditis, iodine deficiency, or certain medications.
In contrast, hyperthyroidism results from an overactive thyroid gland that produces too much thyroid hormone. Graves’ disease, an autoimmune condition, is the most common cause of hyperthyroidism.
Two other thyroid conditions include thyroid nodules and thyroiditis.
Thyroid nodules are growths or lumps in the thyroid gland. While they are often benign, they can sometimes lead to hyperthyroidism. Thyroid nodules may not always cause symptoms but can sometimes be felt as a lump in the neck.
Thyroiditis is inflammation of the thyroid gland, which can cause either hyperthyroidism or hypothyroidism.
Dr. Mahtani’s methodology for thyroid health focuses on a whole-body investigation, including autoimmune triggers, key nutrient deficiencies, and adrenal health. Her goal is not just to normalize TSH levels, but to create a personalized plan that helps you feel energized, clear-headed, and well. As a holistic thyroid doctor, she integrates lifestyle, nutrition, and stress balance to restore thyroid harmony naturally.

What Are The Symptoms of Thyroid Issues?
Symptoms of both hypothyroidism and hyperthyroidism often begin slowly and become more noticeable over time. Women are more likely than men to have thyroid diseases, especially right after pregnancy and after menopause.
Some symptoms of hypothyroidism include:
Constipation
Hypothyroidism can slow down digestive processes, leading to difficulty passing stool and infrequent bowel movements.
Feeling Cold
A sluggish metabolism, common in hypothyroidism, can reduce the body’s ability to generate heat, making individuals more sensitive to cold temperatures.
Depression
Low thyroid hormone levels can affect neurotransmitter function in the brain, contributing to symptoms of depression and mood changes.
Dry Skin and Hair
Reduced thyroid hormone levels can decrease the production of oils that keep the skin and scalp moisturized, resulting in dryness and brittle hair.
Fatigue
Insufficient thyroid hormones can impair cellular energy production, leading to persistent fatigue and low energy levels.
Joint or Muscle Pain or Weakness
Thyroid hormones regulate metabolism and energy production within muscle cells. Decreased levels of thyroid hormones can result in reduced muscle metabolism, leading to muscle weakness and fatigue. This deficiency can also affect the structure and function of connective tissues in joints, potentially leading to joint pain and stiffness.
Reduced Sweating
Hypothyroidism can reduce the body’s ability to regulate temperature, resulting in decreased sweating and difficulty cooling down during physical activity or in warm environments.
Slow Heart Rate
Thyroid hormones are essential in regulating heart rate and rhythm. Low levels can lead to a slower heart (less than 60 BPM), referred to as bradycardia.
Unexplained Weight Gain
A sluggish metabolism caused by hypothyroidism can lead to weight gain, as the body burns fewer calories at rest and stores more energy as fat.
Some symptoms of hyperthyroidism include:
Anxiety or Irritability
Hyperthyroidism can overstimulate the nervous system, leading to feelings of anxiety, nervousness, or irritability.
Bulging, Redness, or Irritated Eyes
Hyperthyroidism, particularly in Graves’ disease, can cause inflammation and swelling of the tissues around the eyes, leading to bulging (proptosis), redness, and irritation.
Diarrhea
Increased thyroid hormone levels can accelerate digestive processes, leading to more frequent bowel movements and diarrhea.
Feeling Hot or Increased Sweating
Hyperthyroidism can raise the body’s basal metabolic rate, leading to increased heat production and sensations of feeling hot or sweating excessively, even in cooler environments.
Insomnia
A heightened metabolic state associated with hyperthyroidism can disrupt sleep patterns, leading to difficulty falling or staying asleep.
Muscle Weakness
Hyperthyroidism can lead to muscle weakness due to the rapid breakdown of muscle tissue and increased protein catabolism.
Rapid or Irregular Heartbeat
Elevated thyroid hormone levels can stimulate the heart, leading to a faster-than-normal heart rate (tachycardia), palpitations or irregular heartbeats (arrhythmias).
Trembling Fingers or Hands
Excess thyroid hormones can stimulate the nervous system, leading to tremors, particularly in the hands or fingers, which may be noticeable during fine motor tasks.
Unexplained Weight Loss
An increase in metabolism and energy expenditure can lead to unintentional weight loss despite increased appetite and food intake.
Thyroid Issues Explained
The body’s responses to thyroid dysfunction aim to maintain homeostasis, but when thyroid hormone levels are imbalanced, these responses can manifest as a range of symptoms and health concerns.
In hypothyroidism, where thyroid hormone levels are low, the body’s metabolic processes slow down as thyroid hormones play a key role in regulating metabolism. This slowdown is the body’s way of conserving energy in response to perceived thyroid hormone deficiency.
Conversely, in hyperthyroidism, where thyroid hormone levels are high, the body’s metabolic processes speed up. Thyroid hormones stimulate cellular metabolism, increasing energy expenditure, heart rate, and other physiological responses. This acceleration is the body’s attempt to compensate for the excess thyroid hormones and restore equilibrium.
A thyroid functional medicine doctor approaches treating thyroid problems holistically. Uncovering the root cause of your thyroid conditions is the first step in restoring a well-functioning thyroid. A healthy thyroid offers many benefits, including:
Symptom Relief
Effective thyroid treatment can alleviate symptoms associated with hypothyroidism or hyperthyroidism, such as fatigue, weight changes, mood swings, and changes in energy levels, improving your overall quality of life.
Balanced Hormones
Restoring normal thyroid hormone levels helps your body regulate metabolism, temperature, heart rate, and other essential functions.
Lower Stress and Stress Management
Chronic stress increases your body’s production and release of the stress hormone cortisol—another driver of inflammation. Learning how to effectively reduce and manage stress can go a long way toward improving your symptoms and reducing psoriasis flares.
Improved Long-Term Health
By treating thyroid disorders, you have a reduced risk of developing related health conditions such as heart disease, osteoporosis, mental health issues, and cancer. Working with a holistic thyroid doctor who understands the complexities of hormone balance ensures that care is both restorative and preventive.
