Unexplained weight gain, constant fatigue, or brain fog can be frustrating—especially when the cause isn’t clear. For many people, these symptoms trace back to the thyroid, a small gland in the neck that aids in metabolism and energy level regulation.
Thyroid disorders are more common than many realize, affecting over 10% of the population and often going undiagnosed for years. Understanding how thyroid imbalances impact your body is key to recognizing symptoms early and finding the right path forward.
Dr. Philip Rabito brings over 20 years of experience diagnosing and treating thyroid disorders with a thoughtful, patient-focused approach. As a trusted endocrinologist in New York City, he combines advanced clinical insight with personalized care to help patients regain balance and feel like themselves again.
Thyroid Disorders - Hypothyroidism
Hypothyroidism occurs when the thyroid idoes not produce enough thyroid hormone to support metabolism. Hypothyroidism is often tied to Hashimoto’s thyroiditis, an autoimmune condition. Common symptoms include:
- Weight gain
- Fatigue
- Depression
- Dry skin
- Elevated cholesterol
- Irregular menstruation
- Impaired memory and concentration
- Increased sensitivity to cold
- Joint pains
- Muscle aches
- Slow heart rate
- Hair loss
- Brittle nails
- Enlarged thyroid gland
Thyroid Disorders - Hyperthyroidism
Hyperthyroidism occurs when the thyroid gland produces abnormally high levels of thyroid hormone, resulting in a hypermetabolic state. An overactive thyroid can be caused by an infection, an autoimmune condition like Graves’ disease, or toxic thyroid nodules.Â
Common symptoms seen in hyperthyroidism are:
- Anxiety and/or hyperactivity
- Tremor
- Palpitations
- Weight loss
- Rapid heart rate
- Sensitivity to heat and excessive
- Sweating
- Bulging eyes
- Insomnia
- Frequent bowel movements
- Irregular menstruation
- Enlarged thyroid gland
Thyroid Gland Disorders
In addition to hypothyroidism and hyperthyroidism, the thyroid gland is also subject to structural abnormalities. The thyroid can become enlarged, a condition known as goiter, which may lead to difficulty swallowing, breathing, and voice hoarseness.
Lumps, or nodules, can also develop on the thyroid gland. These nodules can be benign or cancerous. Thyroid cancer is the fastest-growing malignancy, and it is extremely curable when detected in its early stages. Therefore, it is imperative to have a thyroid specialist inspect and monitor your thyroid nodules to assess the ongoing risk of cancer.
How Do You Diagnose Thyroid Conditions?
Thyroid problems are diagnosed through a combination of physical examination, bloodwork, and specialized tests. Our Ultrasound Technician uses thyroid ultrasound to make an accurate diagnosis.Â
Ultrasounds send sound waves into the body, which are bounced back by hitting tissues. The process is entirely painless, but it allows the doctor to gain a visual image of your thyroid and determine its size, shape, and any abnormalities.
Before you are given a thyroid ultrasound, the technician will perform an intake assessment to learn more about your medical history, including any thyroid risks you may have based on your family’s history of thyroid problems and your lifestyle habits.
What Are the 3 Main Thyroid Tests?
There are three types of tests used to help doctors diagnose thyroid conditions: TSH, T3 and T4, and thyroid antibodies site.
- TSH Test — This test measures your thyroid’s ability to produce the thyroid-stimulating hormone. When patients exhibit symptoms of hypothyroidism or hyperthyroidism, measuring TSH is typically the doctor’s first diagnostics test. Once he knows your current TSH levels, Dr. Rabito can determine what additional tests may be required to develop an accurate treatment plan.
- T3 and T4 Tests — T3 and T4 levels reflect the presence of triiodothyronine (T3) and thyroxine (T4) in your bloodstream. Evaluating these levels can help the doctor determine whether your symptoms are more likely to be caused by hyperthyroidism or hypothyroidism.
- Thyroid Antibodies Test — Thyroid antibodies can reveal whether or not your immune system is targeting your thyroid due to infection or disease. This type of test can often help the doctor diagnose thyroid autoimmune diseases such as Graves’ disease or Hashimoto’s disease.
We always choose the simplest thyroid tests first to get a baseline understanding of your current thyroid function. If the basic tests are effective, we can make diagnoses and develop treatments without the need for extensive blood work.
Ultimately, we work with each patient one-on-one to determine what types of tests they need to get the most accurate diagnoses and best treatments.
Treatment Options for Thyroid Disorders
Dr. Philip Rabito offers a variety of treatments to help patients regain hormonal balance and improve their health.
Hypothyroidism Treatments
Hypothyroidism is typically treated with thyroid hormone replacement therapy, most often using levothyroxine. This medication restores normal hormone levels, easing symptoms like fatigue, weight gain, and cold sensitivity. Regular checkups help us make sure your dosage stays just right.
Hyperthyroidism Treatments
For hyperthyroidism, treatment options include:
- Medications: Antithyroid drugs reduce the production of excess thyroid hormones.
- Radioactive Iodine Therapy: This safe and effective treatment reduces overactive thyroid tissue.
- Beta-Blockers: These help manage symptoms like a fast heart rate or tremors.
- Surgery: In severe cases or for large goiters, removing part or all of the thyroid may be necessary.
Treating Thyroid Nodules and Structural Issues
Thyroid nodules may require monitoring or treatment depending on their size and whether they cause symptoms. Benign nodules often just need regular checkups, while suspicious or cancerous nodules may need surgical removal.Â
For thyroid cancer, Dr. Rabito may use surgery and sometimes radioactive iodine therapy to give you the best outcome.
Managing Autoimmune Thyroid Conditions
Conditions like Hashimoto’s or Graves’ disease often require a targeted approach to balance hormone levels and address symptoms. Treatments depend on whether these conditions lead to underactive or overactive thyroid function.
Long-Term Management Strategies for Thyroid Health
Keeping your thyroid healthy is a lifelong process. Dr. Philip Rabito works with patients to create practical plans to stay on track. He’ll encourage you to do the following for the sake of your thyroid health:Â

Frequently Asked Questions
Can Thyroid Disorders Affect Fertility?
Yes, thyroid disorders can impact fertility in both men and women. Hypothyroidism and hyperthyroidism can disrupt hormone levels, affecting ovulation in women and sperm production in men. Proper diagnosis and treatment can often improve fertility outcomes.
How Do I Manage My Thyroid Condition During Pregnancy?
Managing a thyroid condition during pregnancy requires close monitoring. Hormone levels can change throughout pregnancy, so adjustments to medication may be needed to support your health and your baby’s development. Regular checkups with your doctor are essential.
What Is Subclinical Hypothyroidism, and Does It Need Treatment?
Subclinical hypothyroidism means your thyroid function is slightly low, but you may not have noticeable symptoms. Treatment depends on factors like your TSH levels, age, and health. In some cases, especially for pregnant women or those trying to conceive, treatment may be recommended.
What Are the Risks of Thyroid Surgery?
Thyroid surgery is generally safe, but like any procedure, it carries risks. These may include bleeding, infection, changes in voice, or damage to nearby structures like the parathyroid glands. Choosing an experienced surgeon minimizes these risks.
What Is the Recovery Like After a Thyroidectomy?
Recovery from thyroid surgery is usually smooth. Most patients can return to normal activities within a week or two. You may experience mild discomfort or swelling, and if the entire thyroid is removed, you’ll need lifelong thyroid hormone replacement therapy.
How Does My Lifestyle Impact My Thyroid Health?
Lifestyle factors, like diet, stress, and sleep, can influence thyroid function. A healthy lifestyle supports hormone balance, while excessive stress or nutrient deficiencies may worsen thyroid problems.
How Can My Diet Help Manage My Thyroid Disorder?
A balanced diet can support thyroid health.
For hypothyroidism, make sure you’re getting enough iodine, selenium, and zinc, and avoid excess goitrogens from raw cruciferous vegetables.
For hyperthyroidism, avoiding excessive iodine can help. Consulting a healthcare provider or nutritionist ensures your diet aligns with your specific needs.
How Often Should Thyroid Levels Be Checked?
The frequency of thyroid testing depends on your diagnosis and treatment plan. If you’ve been newly diagnosed or recently started medication, Dr. Rabito may check your levels every 6–8 weeks to adjust dosing. Once your hormone levels are stable, testing is typically done every 6–12 months.
Regular monitoring helps catch changes early and keeps your treatment on track, especially since thyroid hormone levels can shift over time.
Can Thyroid Disorders Affect Sleep Patterns?
Yes, thyroid disorders can significantly impact sleep.
An overactive thyroid may lead to difficulty falling or staying asleep due to symptoms like anxiety, a rapid heart rate, and increased metabolism. People may also experience night sweats or restlessness.
On the other hand, an underactive thyroid can cause excessive fatigue and daytime sleepiness, even after a full night’s rest. Some individuals may also develop sleep apnea, particularly with hypothyroidism.
Can Thyroid Disorders Affect Heart Health?
Yes, thyroid disorders can significantly impact heart health.
Hypothyroidism may slow your heart rate and contribute to higher cholesterol levels, raising the risk of heart disease over time. Hyperthyroidism, on the other hand, can lead to a rapid or irregular heartbeat, raising the risk of conditions like atrial fibrillation.
If left untreated, these effects can place extra strain on the heart. Managing thyroid hormone levels helps to protect cardiovascular health and reduce complications, making regular monitoring and treatment an important part of long-term care.
Can Thyroid Conditions Cause Digestive Issues?
Yes, thyroid conditions can affect how your digestive system functions.
Hypothyroidism often slows digestion, which may lead to constipation, bloating, and a feeling of fullness. In contrast, hyperthyroidism can speed things up, causing frequent bowel movements or diarrhea. These changes happen because thyroid hormones help regulate metabolism, including the rate at which food moves through your system.
In some cases, people with autoimmune thyroid disorders may also have a higher risk of related digestive conditions. Treating the underlying thyroid imbalance can often help improve digestive symptoms and restore more normal bowel habits.
Can Medications Other Than Thyroid Drugs Affect Thyroid Function?
Yes, several medications can influence thyroid function or interfere with thyroid hormone levels.
- Drugs such as lithium, amiodarone, and certain immune therapies can affect how the thyroid produces or uses hormones.
- Calcium or iron supplements may interfere with the absorption of thyroid medication if taken too close together.
- Herbal supplements like ashwagandha may alter thyroid levels or stimulate the thyroid.
It’s important to let Dr. Rabito know about all medications and supplements you’re taking so he can monitor your thyroid levels and adjust your treatment plan if needed.
Are Thyroid Conditions Temporary or Lifelong?
Some thyroid conditions are temporary, while others require lifelong management. For example, thyroiditis caused by inflammation or infection may resolve on its own over time.
However, autoimmune conditions like Hashimoto’s disease or Graves’ disease are typically chronic and need ongoing care. Even when symptoms improve, regular monitoring is important to keep hormone levels balanced.
With the right treatment plan, many people manage thyroid disorders successfully and maintain a good quality of life, whether the condition is short-term or long-term.
