Insights

This study on spontaneous primary hypothyroidism in Saudi Arabia found that symptoms like tiredness and cold intolerance are common. Early detection is possible with clinical findings, aiding physicians in diagnosing this thyroid condition.

Area of Science:

  • Endocrinology
  • Internal Medicine
  • Epidemiology

Background:

  • Spontaneous primary hypothyroidism is a significant endocrine disorder.
  • Understanding its prevalence and clinical presentation in specific populations is crucial for early diagnosis and management.

Purpose of the Study:

  • To analyze the clinical characteristics and prevalence of spontaneous primary hypothyroidism in adult patients at King Fahd Hospital of the University (KFHU), Al-Khobar.
  • To identify key symptoms and signs associated with low free thyroxine index (FT4I) in this patient cohort.

Main Methods:

  • Retrospective analysis of 309 hypothyroidism cases, with detailed evaluation of 124 adult patients meeting inclusion criteria for spontaneous primary hypothyroidism.
  • Data collection included patient demographics, biochemical thyroid function tests (FT4I), and clinical manifestations.

Main Results:

  • The prevalence of undiagnosed primary hypothyroidism in Saudis was 5.2/1000 females and 0.94/1000 males.
  • Low FT4I was observed in 65% of patients and correlated with symptoms such as tiredness, cold intolerance, constipation, weight gain, menstrual disturbances, dry skin, hoarseness, and signs like coarse skin and delayed reflex relaxation.
  • Common presenting symptoms included tiredness (56%) and cold intolerance (38%), while signs included coarse skin (53%) and delayed reflex relaxation (32%).

Conclusions:

  • Clinical findings like tiredness, cold intolerance, and skin changes can aid physicians in the early detection of primary hypothyroidism.
  • Further population-based studies are recommended to gather more comprehensive data on hypothyroidism in Saudi Arabia.

Hyperthyroidism I: Introduction01:25

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...
Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
Graves' Disease I: Introduction01:28

Graves' Disease I: Introduction

Graves' disease is an autoimmune disorder that causes hyperthyroidism, or overactivity of the thyroid gland. It results from autoantibodies called thyroid-stimulating immunoglobulins (TSIs), which bind to thyroid-stimulating hormone (TSH) receptors, leading to overstimulation of hormone production and a hypermetabolic state.EtiologyAlthough considered idiopathic, Graves’ disease has well-established contributing factors. There is a strong genetic component, with increased prevalence in...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
Goiter01:27

Goiter

Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...
