Thyroid Disorders

The thyroid is a small gland in the neck that controls your body’s metabolism, energy, heart rate, weight, temperature, and mood through thyroid hormones. When the thyroid makes too little hormone (hypothyroidism) or too much hormone (hyperthyroidism), it can affect many parts of the body and cause wide-ranging symptoms.

Thyroid problems often develop slowly and can be missed for a long time because symptoms may look like stress, aging, or lifestyle issues. Proper treatment helps bring hormone levels back to a healthy range and supports better energy, weight control, sleep, focus, and overall well-being. Many thyroid medicines work best when taken regularly and at the same time each day, with follow-up tests to adjust the dose when needed.

Common thyroid conditions

• Hypothyroidism: Low thyroid hormone levels (can cause tiredness, weight gain, dry skin, and slow metabolism)
• Hyperthyroidism: High thyroid hormone levels (can cause weight loss, fast heartbeat, sweating, and anxiety)
• Goiter and thyroid nodules: Enlargement or lumps in the thyroid gland
• Autoimmune thyroid disease: Like Hashimoto’s thyroiditis or Graves’ disease

Common symptoms people notice

• Low energy, fatigue, or sleep problems
• Weight changes (gain or loss)
• Hair fall, dry skin, or brittle nails
• Feeling too cold or too hot
• Fast heartbeat, tremors, or anxiety
• Constipation or frequent bowel movements
• Irregular periods or fertility concerns

Tests doctors may suggest

• TSH, Free T3, Free T4
• Thyroid antibodies (TPO, TgAb) if autoimmune disease is suspected
• Ultrasound (for goiter/nodules), in selected cases
