Understanding Thyroid Disease: Causes, Symptoms, Diagnosis, and Treatment

Introduction

As the best endocrinology hospital in LB Nagar RushCare specializes in diagnosing and treating all types of thyroid disorders. Our dedicated team of endocrinologists provides personalized care backed by comprehensive diagnostics and long-term monitoring to ensure your thyroid health stays on track.

What Is the Thyroid Gland?

The thyroid is a tiny, butterfly-shaped gland situated directly behind the Adam's apple at the front of the neck. Despite its small size, it produces vital hormones, mainly thyroxine (T4) and triiodothyronine (T3), which are crucial for controlling metabolism, development, heart rhythm, digestion, and body temperature. These hormones affect mood and cognitive function, regulate how your body uses energy, and even affect your menstrual cycle. Any thyroid imbalance can have a significant impact on general health and well-being due to its extensive impacts.

Types of Thyroid Disorders

Thyroid disorders fall into two main categories, with several subtypes and varying underlying causes:

1. 1. Hypothyroidism– Underactive thyroid
   When the thyroid doesn’t produce enough hormones, rates of metabolism slow down. Common causes include Hashimoto’s thyroiditis (an autoimmune disorder), iodine deficiency, post-surgical removal, or effects of radiation treatment to the neck.
   Symptoms often include fatigue, unexplained weight gain, dry skin and hair, cold intolerance, muscle cramps, constipation, and depression.


2. 2. Hyperthyroidism– Overactive thyroid
   Excess hormone production speeds up metabolic processes. This often results from Grave’s disease (autoimmune overactivity), toxic nodules (toxic adenoma), or thyroiditis.
   Symptoms may include rapid heartbeat or palpitations, weight loss despite increased appetite, anxiety, tremors, heat intolerance, and increased sweating.


3. 3. Goitre– Enlarged thyroid
   The thyroid may enlarge visibly due to iodine deficiency, autoimmune thyroid disorders, nodules, cysts, or tumors. While not inherently harmful, a large goitre can cause difficulty swallowing or breathing.


4. 4. Thyroid Nodules and Cancer
   Nodules are common—found in nearly half of adults over age 50. Most are benign (non-cancerous), but some require further evaluation via ultrasound-guided FNAC (fine-needle aspiration cytology). Thyroid cancer is usually treatable when detected early.

Causes of Thyroid Disorders

Several factors can disrupt normal thyroid function:

• Autoimmune disease: Antibodies mistakenly attack thyroid tissue in Hashimoto’s or stimulate it in Grave’s disease.
• Iodine deficiency: Thyroid hormone production depends on iodine.
• Surgery or radiation therapy: Removal or damage to thyroid tissue.
• Genetic predisposition: A family history increases risk.
• Medications: Certain drugs can impact thyroid levels.
• Pituitary disorders: Problems in the pituitary gland can affect thyroid regulation.
• Postpartum changes: Women may experience transient thyroiditis after childbirth.

At RushCare Hospital, our endocrinologists identify the precise cause through lab testing, imaging, and clinical evaluation, guiding targeted treatment plans.

Symptoms of Thyroid Disease

Thyroid conditions can be subtle at first, making early recognition key. Symptoms vary between underactive and overactive states.

Hypothyroidism symptoms may include:

• Fatigue and weakness
• Unexplained weight gain
• Dry, coarse skin and brittle hair
• Feeling cold even in warm weather
• Muscle stiffness or cramping
• Heavy or irregular menstrual periods
• Constipation and bloating
• Depression or slowed mental functioning

Hyperthyroidism symptoms may include:

• Rapid heart rate, palpitations
• Nervousness or anxiety
• Insomnia
• Unexplained weight loss
• Heat intolerance and increased sweating
• Tremors in hands or fingers
• Diarrhea or increased bowel movements
• Light or irregular menstrual cycles

Because these symptoms are common, many people dismiss them initially. Routine thyroid screening is crucial—especially for women over 30, anyone with a family history, or those presenting with mood, weight, or energy changes.

How Is Thyroid Disease Diagnosed at RushCare?

At RushCare Hospital, we follow a structured diagnostic pathway for accurate identification and comprehensive thyroid care:

1. 1. Medical History and Physical Exam: Includes symptom review, family history, medication use, and physical assessment of thyroid size and texture.


2. 2. Blood Tests:
   • TSH (Thyroid-Stimulating Hormone): The most sensitive initial test.
   • Free T4 and Free T3: To confirm diagnosis and determine hormone levels.
   • Anti-TPO and Anti-Thyroglobulin Antibodies: To detect autoimmune thyroiditis.
   • Calcitonin/Thyroglobulin (if nodules or cancer are suspected).
3. 3. Ultrasound Imaging:
   • Assesses thyroid structure, nodules, cysts, or enlargement.
   • Guides FNAC for suspicious nodules.
4. 4. Fine-Needle Aspiration Cytology (FNAC): Evaluates abnormal nodules for cancer cells with a minimally invasive sampling procedure.


5. 5. Radioactive Iodine Uptake (RAIU) and Scan: Helps differentiate types of hyperthyroidism by measuring iodine absorption.


6. 6. Additional Tests:
   • Eye exams for Grave’s ophthalmopathy
   • Special scans for cancer staging

Our in-house laboratories ensure fast turnaround times, while our endocrinologists guide patients through each step with clarity and guidance.

Treatment Options Available at RushCare Hospital

Treatment is individualized based on thyroid type, severity, age, and overall health.

Hypothyroidism

• Levothyroxine replacement therapy to restore normal hormone levels.
• Dosing adjusted to TSH results and symptoms.
• Lifelong treatment with annual monitoring ensures effective hormone stabilization.

Hyperthyroidism

• Antithyroid medications like methimazole or PTU to inhibit hormone production.
• Radioactive iodine ablation therapy to destroy overactive tissue.
• Beta-blockers to control pulse, tremors, or anxiety.
• Surgery (thyroidectomy) for large goiters, nodules with suspicion of malignancy, or pregnancy.

Thyroid Nodules and Cancer

• Benign nodules are monitored for changes via ultrasound.
• Malignant or suspicious nodules may be surgically removed (lobectomy or total thyroidectomy), often followed up with radioactive iodine therapy and lifelong hormone replacement.

Goitre Management

• Iodine supplements for deficiency-related enlargement.
• Observation, medications, or surgery depending on size and symptomatology.

Pregnancy and Thyroid

Free from postpartum postpartum thyroiditis. Maintaining a healthy thyroid environment during pregnancy is critical for both mother and baby, which is why we treat expectant patients with tailored care.

Long-Term Management and Follow-Up Care

Thyroid disorders require ongoing monitoring and lifestyle support for sustained wellness.

Importance of Regular Testing

• Hypothyroid patients: TSH is tested 6–8 weeks after dosage adjustments, then annually once stabilized.
• Hyperthyroid patients: Monitoring occurs every 4–6 weeks while on medication, then every 3–6 months in remission.

Lifestyle and Diet Recommendations

• Balanced iodine intake: Salt with standardized iodine; care is taken with seaweed or iodine-rich foods.
• Avoid certain foods if hypothyroid and on medication: grapefruit, soy, and high-fiber foods can affect absorption.
• Regular exercise: Supports metabolism, mood, and weight control.
• Smoking cessation: Reduces risk of Grave’s orbitopathy.
• Stress management and adequate sleep: Supports overall hormonal balance.

When to See a Specialist

Visit an endocrinologist if:

• You exhibit new onset or unexplained thyroid symptoms.
• Your medication becomes ineffective.
• You’re pregnant or planning pregnancy.
• You have nodules or goitre that change in size.

At RushCare, our team includes certified endocrinologists, lab specialists, dietitians, and nurses—all focused on your thyroid recovery journey.

FAQs

Where is the thyroid gland located?

The thyroid gland sits in front of the neck, below the Adam’s apple, wrapping around the windpipe in a small butterfly shape.

• Iodine-rich foods (iodized salt, seafood in moderation)
• Selenium sources (Brazil nuts, eggs)
• Omega‑3 fatty acids for anti-inflammatory effects
• Antioxidant-rich produce like berries, leafy greens
