What causes loss of libido?

Sexual desire naturally changes, but a sustained or distressing change deserves a considerate review. Burnout, poor sleep, anxiety, grief and relationship tension can reduce mental space for intimacy. Depression may lower interest and pleasure more broadly. Hypothyroidism can contribute to tiredness, low mood and reduced desire. Type 2 Diabetes may affect energy, circulation, nerves or sexual function. Pain, vaginal or penile symptoms, erectile difficulties and hormonal changes can alter desire indirectly. Medicines, alcohol and other substances may also play a part. Loss of libido does not identify one cause on its own.

Consider when the change began and whether it followed illness, stress, a new medicine, pregnancy, menopause or relationship difficulty. Write down sleep, mood, pain and other symptoms before an appointment. Speak openly with a partner if that feels safe, without treating desire as an obligation. A clinician can review medicines, check relevant health conditions and offer appropriate tests or counselling. Do not stop prescribed treatment or start hormone products without professional advice.

Arrange a medical review when reduced desire persists, causes distress, affects a relationship, or occurs with marked fatigue, low mood, pain, menstrual or erectile changes, vaginal dryness, or symptoms of a hormonal or metabolic problem. Seek urgent help for thoughts of self-harm, sexual violence or immediate danger at home. A clinician can help with both physical and emotional contributors confidentially.

Could my symptoms, medicines or health conditions be affecting desire? Would checking thyroid or blood sugar be useful? What support is available for pain, mood or relationship concerns?
