Why Patients with Hyperthyroidism Should Not Chew Betel Nut

Generally speaking, hyperthyroidism refers to an overactive thyroid condition. Patients with hyperthyroidism should avoid betel nut due to several reasons, including its stimulating effects on the central nervous system and sympathetic nervous system, its impact on thyroid function, the presence of iodine, exacerbation of emotional instability and insomnia, and damage to oral health. Details are as follows:

1. Stimulation of the central nervous system and sympathetic nervous system: Betel nut contains arecoline, an alkaloid with strong stimulating effects. It can stimulate the central nervous system and sympathetic nervous system, leading to increased heart rate and elevated blood pressure. This may increase the burden on the cardiovascular system and be detrimental to disease stability.

2. Impact on thyroid function: Arecoline and other components in betel nut may interfere with the synthesis, absorption, and metabolism of thyroid hormones. Since patients already have elevated thyroid hormone levels, betel nut consumption may further exacerbate this imbalance, worsening hyperthyroid symptoms.

3. Contains iodine: Betel nut contains some iodine, which is an essential raw material for the synthesis of thyroid hormones. Excessive iodine intake by patients with hyperthyroidism can intensify the synthesis and secretion of thyroid hormones, thereby worsening the condition. Therefore, patients should try to avoid consuming iodine-rich foods, including betel nut.

4. Exacerbation of emotional instability and insomnia: The stimulating effects of arecoline may also lead to increased emotional instability and irritability in patients with hyperthyroidism, potentially causing insomnia and other symptoms. These symptoms can further affect the patient's physical and mental health and hinder disease recovery.

5. Damage to oral health: Long-term betel nut chewing can damage the oral mucosa and increase the risk of oral cancer. Oral health is particularly important for patients with hyperthyroidism because oral infections or other oral problems may trigger or worsen systemic infections, which is detrimental to disease stability.

Patients with hyperthyroidism should also follow their doctor's instructions, maintain a balanced diet, adopt healthy lifestyle habits, manage their emotions effectively, and actively cooperate with treatment.
