Yes, your loss of sexual desire can be related to Hypothyroidism, as low thyroid hormone levels can affect energy, mood, and libido; even if you are taking Thyronorm, symptoms may persist if your thyroid levels are not yet well controlled. It is important to get your thyroid function tests (like TSH) checked regularly and adjust the dose with your doctor if needed; also, factors like stress, fatigue, depression, or other hormonal imbalances can contribute, so a holistic evaluation may help. Make sure you are taking your medicine correctly (on an empty stomach, at the same time daily, and avoiding food for at least 30 minutes after), and maintain a healthy lifestyle with good sleep, a balanced diet, and regular exercise. If the problem continues despite normal thyroid levels, consult your doctor for further assessment and guidance, as it is a common and treatable issue.
