Patients with thyroid nodules are allowed to eat cold drinks, but moderation is recommended. Cold drinks are beverages at lower temperatures, and they contain a lot of sugar, additives and other ingredients, which may have adverse effects on health, and long-term consumption of large quantities of cold drinks may also cause obesity and other undesirable conditions, so although patients with thyroid nodules can consume cold drinks, it is recommended that they do so in moderation. In particular, patients with thyroid nodules who have weak gastrointestinal function are advised to drink less or not drink. It should be noted that patients with hyperthyroidism should avoid foods high in iodine, while patients with hypothyroidism should avoid foods high in fat. Patients diagnosed with thyroid nodules should receive standardized treatment under the guidance of a doctor.
