Living with hyperthyroidism

Hyperthyroidism occurs when the thyroid produces more hormone than the body needs. Feeling anxious, excessive sweating, heat intolerance, difficulty sleeping, diarrhoea, night sweats and palpitations can occur. Symptoms may overlap with other conditions, and their intensity does not by itself show the hormone level.

Treatment may reduce thyroid hormone production or its effects on the heart. Blood tests help the clinician adjust treatment, while eye symptoms, menstrual changes, bone health and pregnancy plans may affect decisions.

Take thyroid medicine exactly as directed and attend scheduled blood tests, even when you feel better. Keep a record of palpitations, sleep, bowel changes, sweating and weight change to share at review. Check before taking iodine-containing products, supplements or a new medicine.

Stay cool, drink regularly, choose lighter activity while symptoms are active and protect sleep with a consistent routine. Limit stimulants if they worsen palpitations or anxiety. Tell your clinician promptly if you are pregnant, planning pregnancy or breastfeeding.

Contact your clinician if palpitations persist, diarrhoea causes dehydration, sweating and heat intolerance interfere with daily life, or symptoms return after treatment. Seek emergency help for a very fast or irregular heartbeat with chest pain, fainting, severe breathlessness, high fever or sudden confusion.

Ask which blood tests you need, how to take your medicine around other products, what symptoms suggest too much or too little thyroid hormone, and which warning signs require urgent help. Discuss pregnancy and exercise plans.
