Area of Science:

• Endocrinology
• Internal Medicine

Background:

• Hypothyroidism stems from insufficient thyroid hormone production or action.
• Causes range from primary issues to central deficiencies and hormone inactivation.
• Subclinical hypothyroidism is defined by elevated TSH with normal free thyroxine.

Purpose of the Study:

• To provide an updated review of hypothyroidism.
• To cover etiology, types, drug interactions, diagnosis, and treatment.

Main Methods:

• Literature review of current research on hypothyroidism.
• Analysis of diagnostic criteria and therapeutic approaches.

Main Results:

• Primary hypothyroidism is most common.
• Subclinical hypothyroidism requires careful monitoring.
• Thyroid hormone replacement is the standard treatment.

Conclusions:

• Understanding hypothyroidism's diverse causes and types is crucial for accurate diagnosis.
• Management focuses on thyroid hormone replacement therapy.
• Ongoing research informs updated treatment guidelines.
