What can aggravate hyperthyroidism in patients recently underwent surgery?

Hyperthyroidism can be aggravated by physical stress, particularly in the context of a patient who has recently undergone surgery. Surgical procedures are inherently stressful to the body, which can exacerbate the symptoms of hyperthyroidism, such as increased heart rate, anxiety, and heightened metabolic demands. This is due to the additional strain placed on the body to heal and recover post-operation, thereby triggering an increase in thyroid hormone production and activity.

Physical stress can also influence the body's hormonal balance, leading to an increased release of catecholamines, which can further stimulate thyroid hormone levels and enhance the hyperthyroid state. In a postoperative context, a patient's body is already under duress, and additional physical stress from either exertion or pain can compound the problem, making it particularly detrimental in cases of hyperthyroidism.

In contrast, infrequent meals, excessive hydration, and a low-calorie diet typically do not pose the same level of risk for exacerbating hyperthyroid symptoms. Infrequent meals may lead to fluctuations in energy levels but are less directly linked to the exacerbation of hyperthyroid conditions. Excessive hydration generally does not have a significant impact on thyroid function, while a low-calorie diet might reduce the metabolic demands on the body, potentially helping
