What does loss of libido feel like with hypothyroidism?

You may notice fewer spontaneous sexual thoughts, less response to touch, or a sense that intimacy requires more effort. Hypothyroidism can slow body processes and is often associated with tiredness, feeling cold, constipation, dry skin, hair changes, weight changes, low mood, and difficulty concentrating. Some people also notice changes in periods, erections, or orgasm. These symptoms overlap with many conditions, so libido alone cannot identify the cause.

Make an appointment if reduced desire continues, especially when it appears with tiredness, cold sensitivity, constipation, or menstrual or erectile changes. A clinician can review your symptoms and medicines and arrange thyroid blood tests when appropriate. Take prescribed thyroid medicine as directed and do not change the dose without advice. Sleep, manageable activity, and an open conversation with a partner may support intimacy while the cause is assessed.

Seek urgent help for confusion, extreme drowsiness, difficulty breathing, fainting, or feeling dangerously unwell. Arrange timely medical review for a rapidly worsening change, pregnancy with thyroid symptoms, or severe low mood. A persistent libido change should be discussed even when other symptoms seem mild.

Could thyroid function explain my libido and energy changes? Which blood tests do I need? Could another medicine or health condition be contributing? If I already take thyroid medicine, does the dose need review?
