Does thyroid hormone replacement treat hypothyroidism?

Hypothyroidism can cause tiredness, feeling cold, constipation, dry skin, slowed thinking and changes in weight. Replacement medicine supplies a form of thyroid hormone that the body can use, helping restore hormone activity and ease symptoms over time.

The right dose differs between people and may change with age, pregnancy, other illnesses or medicines. Symptoms alone cannot show whether the dose is correct; blood-test results and how you feel are considered together.

Take the medicine according to the prescription and keep a consistent routine. Ask a pharmacist or clinician how to separate it from supplements or other medicines that can affect absorption. Do not stop it or change the dose because symptoms improve or a single reading changes.

Attend planned blood-test reviews, especially after starting treatment or changing the dose. Tell your clinician if you become pregnant, start a new medicine or have difficulty taking the tablet regularly.

Contact your clinician if symptoms remain troublesome, return after improvement or suggest that the dose is too strong, such as racing heartbeats, shaking, sweating or unusual nervousness. Seek urgent help for chest pain, severe breathlessness, fainting or a new irregular heartbeat.

What caused my hypothyroidism, and what treatment target are we using? When should my blood tests be repeated? How should I take the medicine alongside my other tablets and supplements?
