Your thyroid is a small, butterfly-shaped gland at the base of your neck, but its impact on your health is enormous. When your thyroid stops working properly, virtually every system in your body can be affected. From unexplained fatigue and weight changes to mood swings and hair loss, thyroid problems are one of the most common yet underdiagnosed conditions in primary care.
Schedule a thyroid evaluation with Dr. Ghadimi at NuGen Medicine today.
Dr. Nima Ghadimi, board-certified internist at NuGen Medicine, sees thyroid conditions frequently in his Scottsdale practice and through telemedicine visits across Arizona, California, Florida, and Colorado. Understanding the signs early can make a significant difference in treatment outcomes and quality of life.
What Does Your Thyroid Do?
The thyroid gland produces hormones, primarily thyroxine (T4) and triiodothyronine (T3), that regulate your body’s metabolism, energy production, and temperature. These hormones influence heart rate, digestion, muscle function, brain development, and bone maintenance. The thyroid is controlled by the pituitary gland through thyroid-stimulating hormone (TSH), which tells the thyroid how much hormone to produce.
When this delicate feedback loop is disrupted, the thyroid may produce too much hormone (hyperthyroidism) or too little (hypothyroidism). Both conditions cause a wide range of symptoms that often mimic other health problems, which is why thyroid disorders are frequently missed or misdiagnosed.
Common Thyroid Problems
Thyroid problems encompass several distinct conditions. The most common thyroid disorders include hypothyroidism, hyperthyroidism, Hashimoto’s thyroiditis, Graves’ disease, thyroid nodules, and goiter. Each presents differently, but all involve disruption of normal thyroid hormone production or gland structure.
Hypothyroidism (Underactive Thyroid)
Hypothyroidism occurs when the thyroid does not produce enough hormones. It is the most common thyroid disorder, affecting roughly 5% of Americans according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK). Women over 40 are at particularly high risk.
Symptoms of hypothyroidism include:
- Persistent fatigue and low energy
- Unexplained weight gain or difficulty losing weight
- Cold intolerance
- Dry skin and brittle hair or nails
- Constipation
- Brain fog and difficulty concentrating
- Depression or low mood
- Muscle weakness and joint pain
- Elevated cholesterol levels
- Irregular or heavy menstrual periods
Hyperthyroidism (Overactive Thyroid)
Hyperthyroidism means the thyroid produces excess hormones, accelerating your metabolism. According to the American Thyroid Association, about 1 in 100 Americans have hyperthyroidism.
Symptoms of hyperthyroidism include:
- Unintentional weight loss despite normal or increased appetite
- Rapid or irregular heartbeat (palpitations)
- Anxiety, nervousness, or irritability
- Tremors in the hands and fingers
- Increased sweating and heat intolerance
- Frequent bowel movements
- Difficulty sleeping
- Thinning hair
- Changes in menstrual patterns
Hashimoto’s Thyroiditis
Hashimoto’s thyroiditis is an autoimmune condition where the immune system attacks the thyroid gland, gradually reducing its ability to produce hormones. It is the most common cause of hypothyroidism in the United States. Hashimoto’s tends to run in families and is more common in women.
Graves’ Disease
Graves’ disease is an autoimmune disorder that causes hyperthyroidism. The immune system creates antibodies that stimulate the thyroid to overproduce hormones. It may also cause eye problems (Graves’ ophthalmopathy) with bulging, irritation, or vision changes.
Thyroid Nodules and Goiter
Thyroid nodules are lumps that form within the thyroid gland. Most are benign, but a small percentage may be cancerous and require further evaluation. A goiter refers to an enlarged thyroid gland, which can occur with either hypothyroidism or hyperthyroidism.
Who Is at Risk for Thyroid Problems?
Thyroid problems can affect anyone, but certain populations face higher risk. According to the Mayo Clinic, risk factors include being female, being over age 40, having a family history of thyroid disease, having an existing autoimmune condition (such as type 1 diabetes or rheumatoid arthritis), previous radiation therapy to the neck or chest, pregnancy or recent childbirth, and iodine deficiency.
Women are five to eight times more likely than men to develop thyroid problems. Hormonal fluctuations during pregnancy, perimenopause, and menopause can all trigger or worsen thyroid dysfunction.
How Are Thyroid Problems Diagnosed?
Thyroid diagnosis starts with a thorough clinical evaluation and a combination of blood tests. The primary tests include TSH (thyroid-stimulating hormone), free T4, and free T3. When TSH is elevated and T4 is low, it indicates hypothyroidism. When TSH is suppressed and T4/T3 are elevated, it points to hyperthyroidism.
At NuGen Medicine, Dr. Ghadimi takes a functional medicine approach to thyroid evaluation. This means going beyond standard TSH testing to include a comprehensive thyroid panel: TSH, free T4, free T3, reverse T3, and thyroid antibodies (TPO and thyroglobulin antibodies). This expanded panel helps identify early thyroid dysfunction, autoimmune thyroiditis, and conversion issues that standard testing may miss.
Additional diagnostic tools may include thyroid ultrasound to evaluate nodules and fine-needle aspiration biopsy if a suspicious nodule is found.

Thyroid Treatment Options
Thyroid treatment depends on the specific condition, its severity, and the patient’s overall health profile. The most common approaches include medication, lifestyle modifications, and in some cases, surgical intervention.
Hypothyroidism Treatment
The standard treatment for hypothyroidism is thyroid hormone replacement medication, most commonly levothyroxine. This synthetic T4 hormone restores normal hormone levels and reverses symptoms. Dosing is individualized based on lab results, symptoms, age, and body weight, with regular monitoring to ensure optimal levels.
Some patients benefit from combination therapy with both T4 and T3 (liothyronine), especially those who continue to experience symptoms despite normal TSH levels on levothyroxine alone. A functional medicine physician can help determine whether combination therapy may be appropriate.
Hyperthyroidism Treatment
Hyperthyroidism treatment options include antithyroid medications (such as methimazole), radioactive iodine therapy, and in some cases, thyroid surgery (thyroidectomy). Beta-blockers may be prescribed to manage symptoms like rapid heart rate and tremors while the underlying condition is being treated.

Functional Medicine Approach
Beyond conventional medication, a functional medicine approach to thyroid health examines contributing factors such as nutrient deficiencies (selenium, zinc, iron, vitamin D, iodine), gut health and intestinal permeability, chronic stress and cortisol dysregulation, environmental toxin exposure, and food sensitivities that may trigger autoimmune flares.
Dr. Ghadimi integrates conventional endocrinology with integrative medicine principles to develop personalized treatment plans that address the root causes of thyroid dysfunction, not just the symptoms.
When to See a Doctor About Your Thyroid
You should schedule a thyroid evaluation if you experience persistent fatigue that does not improve with rest, unexplained weight changes (gain or loss), mood changes including depression or anxiety without a clear cause, changes in heart rate or blood pressure, hair loss or changes in skin and nail quality, difficulty regulating body temperature, or a visible lump or swelling in your neck.
If you have been feeling “off” but cannot pinpoint why, thyroid dysfunction may be the underlying cause. Many patients describe months or even years of vague symptoms before receiving a thyroid diagnosis.

Frequently Asked Questions About Thyroid Problems
What is the most common thyroid problem?
Hypothyroidism (underactive thyroid) is the most common thyroid disorder. It affects approximately 5% of the U.S. population, with Hashimoto’s thyroiditis being the leading cause. Women over 40 are at the highest risk.
Can thyroid problems cause weight gain?
Yes. Hypothyroidism slows your metabolism, which can lead to weight gain even without changes in diet or activity level. If you are experiencing unexplained weight gain, a thyroid panel should be part of your evaluation. NuGen Medicine also offers medical weight loss programs for patients whose weight management is complicated by thyroid dysfunction.
How is thyroid disease diagnosed?
Thyroid disease is diagnosed primarily through blood tests measuring TSH, free T4, and free T3 levels. A comprehensive panel also includes thyroid antibodies and reverse T3. Physical examination and thyroid ultrasound may also be used.
Can you treat thyroid problems naturally?
While thyroid medication is typically necessary for clinical hypothyroidism or hyperthyroidism, lifestyle factors can support thyroid function. These include ensuring adequate selenium, zinc, and vitamin D intake, managing stress, maintaining gut health, avoiding excessive processed foods, and getting regular exercise. A functional medicine approach helps identify and address these factors alongside conventional treatment.
Can stress affect your thyroid?
Yes. Chronic stress elevates cortisol, which can interfere with thyroid hormone production and conversion. Stress can also trigger or worsen autoimmune thyroid conditions like Hashimoto’s and Graves’ disease. Stress management is an important part of comprehensive thyroid care.
Should I see an endocrinologist or a primary care doctor for thyroid issues?
Many thyroid conditions can be effectively managed by an experienced primary care physician or internist. Dr. Ghadimi at NuGen Medicine manages thyroid conditions as part of comprehensive primary care, using both conventional and functional medicine approaches. Complex cases or thyroid cancer may require referral to an endocrinologist.
