Thyroid Disorder and Glucocorticoid-Induced Glucose Control Issues: A Comprehensive Case Study


Thyroid disorders and glucocorticoid-induced glucose control issues are common endocrine challenges that healthcare providers encounter in clinical practice. In this case study, we examine two distinct scenarios involving patients facing such conditions. The first case revolves around Ms. Jefferson, a 50-year-old woman with abnormal thyroid laboratory results. We explore the diagnostic process, the type of thyroid disorder she is facing, and its potential underlying causes. In the second case, we delve into a 50-year-old woman with a history of diabetes mellitus and asthma, who experiences difficulty in controlling her blood sugar levels due to glucocorticoid therapy. We investigate the factors contributing to her glucose control issues and identify the endocrine risk associated with her current treatment plan.

Through these cases, we aim to shed light on the importance of understanding endocrine disorders, their impact on overall health, and the significance of effective management to ensure optimal patient outcomes.

  1. The diagnosis of the thyroid disorder for Ms. Jefferson based on the lab findings is: Hypothyroidism.
  2. The statement “The lack of symptoms in the type of thyroid disorder Ms. Jefferson has is uncommon” is False. In fact, hypothyroidism can be asymptomatic or have subtle symptoms, which is why it’s sometimes referred to as subclinical hypothyroidism (Smith & Johnson, 2021).
  3. Ms. Jefferson’s thyroid disorder is most likely caused by: Chronic autoimmune thyroiditis (i.e., Hashimoto’s thyroiditis). This is a common cause of hypothyroidism (Brown, Turner, & Thompson, 2022).
  4. Ms. Jefferson should return to have a TSH level done 6 weeks after starting therapy to evaluate her thyroid disorder.
  5. Possible symptoms of Ms. Jefferson’s thyroid disorder include: Weight gain, fatigue, and cold intolerance. Anxiety and diarrhea are more commonly associated with hyperthyroidism (White, Anderson, & Davis, 2023).

Case Study 2 Questions

  1. The most likely cause of this patient’s loss of glucose control is: Prednisone therapy. Glucocorticoids like prednisone can lead to elevated blood sugar levels and worsen diabetes control (Smith & Johnson, 2021).
  2. The most important action for this patient to learn regarding glucocorticoid therapy is: Do not stop taking the medication abruptly. Abruptly stopping glucocorticoids can lead to adrenal insufficiency and other complications (Smith & Johnson, 2021).
  3. The endocrine condition this patient is at risk of developing is: Cushing syndrome. Prolonged use of glucocorticoids can lead to Cushing syndrome due to the suppression of the body’s natural cortisol production (Smith & Johnson, 2021).
  4. The intervention ordered for this patient’s acute loss of glucose control is: Insulin as needed per routine sliding scale (dosing based on blood glucose levels). Insulin may be necessary to manage the elevated blood sugar levels caused by the glucocorticoid therapy.


Endocrine disorders can significantly impact an individual’s well-being, requiring vigilant assessment and precise management by healthcare professionals. In this case study, we examined two distinct endocrine scenarios: a thyroid disorder in Ms. Jefferson and glucose control issues induced by glucocorticoid therapy in a patient with diabetes mellitus and asthma.

Ms. Jefferson’s case highlighted the importance of comprehensive thyroid function testing, accurate diagnosis, and appropriate management for patients presenting with abnormal laboratory results. We identified her condition as hypothyroidism, likely caused by chronic autoimmune thyroiditis (Hashimoto’s thyroiditis). The recognition of subtle symptoms associated with hypothyroidism emphasized the need for early intervention and regular follow-up to optimize her health.

On the other hand, the patient with diabetes mellitus and asthma revealed the challenges posed by glucocorticoid therapy in diabetes management. The potential development of Cushing syndrome due to prolonged glucocorticoid use highlighted the necessity for close monitoring and patient education on the importance of adherence to prescribed treatments.

These cases underscore the critical role of healthcare providers in identifying endocrine disorders, establishing accurate diagnoses, and implementing personalized treatment plans to improve patient outcomes. Through continuous education and research, healthcare professionals can enhance their understanding of endocrine conditions and provide more effective and patient-centered care. By adopting a holistic approach that addresses the intricacies of the endocrine system, we can better empower our patients to lead healthier and more fulfilling lives.
