Quick answer

Discuss thyroid testing with an MD physician if persistent fatigue, unexplained weight change, heat or cold intolerance, palpitations, tremor, constipation, dry skin, hair changes, menstrual changes or neck swelling occurs. Symptoms overlap with many conditions and cannot diagnose thyroid disease without clinical review and suitable blood tests.

What does the thyroid do?

The thyroid is a small gland in the front of the neck that produces T4 and T3 hormones. These hormones influence energy use, heartbeat, temperature, bowel function, muscles and menstrual health. Pituitary TSH signals the thyroid to produce hormone.

Hypothyroidism means too little thyroid hormone; hyperthyroidism means too much. Goitre, nodules and thyroiditis are related but different concerns. A neck lump does not automatically mean abnormal hormone levels.

Possible hypothyroidism symptoms

Fatigue, weight gain, cold intolerance, dry skin, thinning hair, constipation, muscle pain, heavy or irregular periods, slow heart rate and low mood may occur. These are common symptoms with many possible causes, including anaemia, sleep problems and medicines, so do not self-start thyroid hormone.

Possible hyperthyroidism symptoms

Palpitations, rapid or irregular heartbeat, heat intolerance, sweating, hand tremor, weight loss, anxiety, poor sleep, frequent bowel movements and muscle weakness may occur. Older people may have subtle symptoms. Persistent palpitations need assessment rather than being assumed to be stress.

When should you see a doctor?

Arrange review for persistent symptoms, neck swelling, an abnormal TSH/T4 report, pregnancy planning, infertility assessment, unexplained high cholesterol, or changed symptoms while taking thyroid medicine. Contact your doctor promptly after a positive pregnancy test if you already use thyroid hormone.

How are thyroid tests interpreted?

NIDDK describes TSH as the usual first test of thyroid function. High TSH can suggest an underactive thyroid and low TSH an overactive thyroid, but interpretation also considers T4, symptoms, pregnancy, pituitary health and medicines. T3, thyroid antibodies or imaging may be selected when appropriate.

Biotin supplements and medicines such as amiodarone or lithium can affect results or thyroid function. Tell the clinician about all supplements. One borderline result does not always mean lifelong treatment.

Treatment and follow-up

Hypothyroidism is commonly treated with levothyroxine. Dose depends on age, weight, heart health, pregnancy and results. Follow instructions about timing and separation from iron, calcium or food. Do not change dose or stop medicine by yourself.

Hyperthyroidism treatment depends on cause and may include antithyroid medicine, radioactive iodine, surgery or symptom-control medicine. Complex cases, pregnancy, nodules or difficult control may need endocrinology referral.

Iodine and supplements

More iodine does not automatically improve thyroid health. Kelp, seaweed and high-dose iodine supplements can worsen some autoimmune thyroid conditions. “Natural thyroid boosters” are not substitutes for prescribed hormone.

Choosing appropriate physician care

Look for recognised qualifications, careful interpretation, medication safety and a clear follow-up plan. Avoid promises of a universal permanent cure. Dr. Ajay T.
