What could be the reason for hoarseness in hyperthyroidism?

Hyperthyroidism usually refers to hyperfunction of the thyroid gland. Under normal circumstances, patients with hyperthyroidism may experience hoarseness due to various causes, such as excessive voice use, dry environment, adverse drug reactions, enlarged thyroid gland compressing the recurrent laryngeal nerve, or thyroiditis affecting the larynx. If discomfort symptoms occur, it is recommended to seek timely treatment at a regular hospital. Detailed explanations are as follows:

1. Excessive Voice Use

Excessive voice use, such as speaking loudly for long periods or frequently clearing the throat, can continuously irritate the vocal cord mucosa, leading to congestion and edema, which can cause hoarseness. Reduce prolonged and continuous voice use, control the volume when speaking, and allow sufficient rest for the vocal cords. Drinking warm water frequently to moisturize the throat and taking mild throat lozenges may help.

2. Dry Environment

Low humidity or overly dry air in the environment can cause moisture loss from the throat mucosa, making the mucosa dry and prone to damage, which can lead to hoarseness. Use a humidifier to adjust indoor humidity to between 40% and 60%. Wear a mask when going outside to reduce direct irritation of dry air on the throat.

3. Adverse Drug Reactions

Medications used to treat hyperthyroidism may cause adverse reactions such as laryngeal mucosal edema, resulting in hoarseness, possibly accompanied by symptoms like itching skin, rashes, etc. The medication should be stopped immediately and medical attention sought. Under a doctor's guidance, use Loratadine Syrup, Cetirizine Hydrochloride Tablets, or Dexamethasone Acetate Tablets to relieve symptoms, and adjust the treatment plan accordingly.

4. Enlarged Thyroid Compressing the Recurrent Laryngeal Nerve

Patients with hyperthyroidism often have an enlarged thyroid gland. If the enlargement is significant, it may compress the recurrent laryngeal nerve, affecting the normal movement of the vocal cords, causing hoarseness, and possibly accompanied by a foreign body sensation during swallowing. Under a doctor's guidance, use Methimazole Tablets, Propylthiouracil Tablets, or Metoprolol Tartrate Tablets to control the condition and reduce thyroid enlargement. Surgical treatment options should be evaluated if necessary.

5. Thyroiditis Affecting the Larynx

During a thyroiditis episode, inflammation may spread to surrounding tissues, affecting the larynx, causing inflammatory reactions in the laryngeal mucosa, and resulting in hoarseness and throat pain. Patients should follow medical advice to use Ibuprofen Sustained-release Capsules, Prednisone Acetate Tablets, or Levothyroxine Sodium Tablets for treatment. At the same time, avoid consuming spicy and irritating foods to reduce throat irritation.

In daily life, maintain a regular routine and avoid excessive fatigue. Eat a light diet, consume more fresh vegetables and fruits to supplement vitamins. Regularly revisit the hospital to monitor thyroid function for timely adjustment of treatment plans.
