What are the symptoms of hypothyroidism?

When the thyroid makes too little hormone, body processes may slow. You might notice reduced energy, difficulty concentrating, a hoarse voice, muscle aches, puffiness around the face, or heavier or irregular periods. Hair may become dry or thin, and the hands and feet may feel cold. A swelling at the front of the neck can be a goitre. These symptoms overlap with many other conditions, so a symptom list cannot confirm the cause.

Arrange a clinical review if tiredness, cold intolerance, bowel changes or weight change persist. A clinician may ask about family history, pregnancy, medicines and previous thyroid problems, then request a Thyroid Function Test. Keep a note of symptoms and when they started. If hypothyroidism is confirmed, Thyroid Hormone Replacement is commonly monitored and adjusted through follow-up rather than changed according to symptoms alone.

Seek urgent help for severe drowsiness, confusion, difficulty staying awake, very slow breathing, chest pain or fainting. Contact a clinician promptly if symptoms are rapidly worsening or if a neck swelling causes difficulty swallowing or breathing. A routine review is suitable for gradual symptoms without these warning signs.

Could my symptoms be related to thyroid hormone levels? Which tests will clarify this? If treatment is started, when should it be reviewed and what should I do if symptoms change?
