Hypothyroidism vs. Hyperthyroidism in Women: Key Differences, Symptoms & Treatments

Your thyroid plays a critical role in regulating metabolism, energy, and hormones. But when it’s out of balance, it can lead to serious health issues. Many women struggle with thyroid imbalance, experiencing fatigue, weight changes, mood swings, and more. But is it hypothyroidism or hyperthyroidism? Understanding the differences between an underactive vs. overactive thyroid can help you get the right diagnosis and treatment.

Hypothyroidism vs. Hyperthyroidism: The Basics

• Hypothyroidism (Underactive Thyroid): The thyroid doesn’t produce enough hormones, slowing down metabolism.
• Hyperthyroidism (Overactive Thyroid): The thyroid produces too many hormones, speeding up metabolism.

Symptoms: How to Spot the Differences

Hypothyroidism vs Hyperthyroidism Symptoms

Causes of Thyroid Disorders

Hyperthyroidism vs Hypothyroidism Causes

• Hypothyroidism: Hashimoto’s disease (autoimmune), iodine deficiency, or thyroid removal.
• Hyperthyroidism: Graves’ disease (autoimmune), thyroid nodules, or excess iodine.

Diagnosis: How to Test for Thyroid Disorders

Hypothyroidism vs Hyperthyroidism Diagnosis

Doctors use thyroid function tests to check hormone levels:

• TSH test: High TSH suggests hypothyroidism; low TSH suggests hyperthyroidism.
• T3 & T4 tests: Measures thyroid hormone levels in women.
• Antibody tests: Detect autoimmune thyroid diseases like Hashimoto’s or Graves’ disease.

Treatment Options

Hyperthyroidism vs Hypothyroidism Treatment

• Hypothyroidism: Thyroid hormone replacement therapy (levothyroxine).
• Hyperthyroidism: Medications, radioactive iodine, or surgery to reduce thyroid activity.

Thyroid Medication Side Effects

• Hypothyroidism meds: Can cause palpitations, insomnia if dosage is too high.
• Hyperthyroidism meds: May lead to liver issues, fatigue, or allergic reactions.

How Thyroid Disorders Affect Women’s Health

Thyroid Issues and Menstrual Cycle
