This study highlights that delayed diagnosis of hypothyroidism is common, with many patients experiencing symptoms for years. Elevated thyroid-stimulating hormone (TSH) levels strongly correlate with hypothyroidism, underscoring its diagnostic importance.

Area of Science:

  • Endocrinology
  • Internal Medicine

Background:

  • Hypothyroidism is a common endocrine disorder with varied clinical presentations.
  • Early diagnosis and treatment are crucial for managing hypothyroidism and preventing complications.

Purpose of the Study:

  • To analyze the demographic, etiological, and clinical characteristics of hypothyroid patients.
  • To investigate the diagnostic utility of serum thyroxine (T4) and thyroid-stimulating hormone (TSH).
  • To assess the delay between symptom onset and diagnosis in hypothyroidism.

Main Methods:

  • A retrospective study of 58 hypothyroid patients at the University Hospital of the West Indies.
  • Data collection included patient demographics, underlying causes, presenting symptoms, and biochemical parameters (T4 and TSH).
  • Analysis of the time from symptom presentation to diagnosis.

Main Results:

  • The majority of patients were female (86.2%) and aged 21-70 years.
  • Idiopathic hypothyroidism was the most common cause (60.3%), followed by post-thyroidectomy (22.4%) and post-I131 therapy (10.4%).
  • Elevated TSH levels were observed in 79.2% of patients, confirming a strong correlation with hypothyroidism. Significant delays in diagnosis were noted, with 46.5% diagnosed within one year and 39.6% between 2-10 years.
  • Common symptoms included lethargy (34.5%), anemia (27.6%), and slow relaxation of tendon reflexes (27.6%).

Conclusions:

  • This study underscores the significant delay in diagnosing hypothyroidism, emphasizing the need for increased clinical awareness of its diverse presentations.
  • Elevated TSH is a reliable indicator for diagnosing hypothyroidism.
  • Further research is needed to explore the association between hypothyroidism and other autoimmune disorders in this population.
