What can hyperthyroidism result in?

If it continues without effective control, it can place extra strain on the heart and affect muscles, bones, and daily functioning.

Excess thyroid hormone speeds many body processes. You may notice palpitations, feeling anxious, difficulty sleeping, excessive sweating, diarrhoea, or night sweats. Some people develop weakness, weight change, or reduced exercise tolerance. The pattern and severity vary, and these symptoms can also occur with other conditions.

Long-standing excess hormone can contribute to irregular heart rhythm and bone weakening. Thyroid eye disease may cause gritty eyes, pressure, or changes around the eyes in some people. A diagnosis requires assessment rather than matching one symptom to one condition.

Arrange a medical review for persistent symptoms or a new diagnosis. Blood tests guide treatment, and your clinician may review medicines, pulse, blood pressure, and other health conditions. Take prescribed treatment as directed and do not change the dose because a symptom briefly improves.

Get emergency help for chest pain, severe breathlessness, fainting, confusion, or a very fast or irregular heartbeat. Urgent review is also needed for rapidly worsening agitation, high fever, vomiting, or profound weakness, particularly when hyperthyroidism is untreated.

Ask which effects your thyroid level may explain, how treatment will be monitored, whether your heart or bones need assessment, and which warning symptoms should prompt immediate help.
