To Treat or Not to Treat? Managing Subclinical Hypothyroidism
Published: Nov 28, 2023
Deciding whether to treat subclinical hypothyroidism can be challenging. Here's what you need to know about treatment options and when they're necessary.
When Is Treatment Recommended?
Treatment is generally recommended for individuals with TSH levels above 10 mU/L due to the risk of progressing to overt hypothyroidism. These patients might benefit from thyroid hormone replacement therapy. For those with TSH levels between 4.5 and 10 mU/L, treatment decisions are based on age, symptoms, and risk factors.
The Role of Thyroid Hormone Therapy
Thyroid hormone replacement, typically with levothyroxine, is the standard treatment for subclinical hypothyroidism. It aims to normalize TSH levels and alleviate any mild symptoms. However, the benefits of treatment, especially in asymptomatic individuals, remain a subject of debate among experts.
Potential Risks of Treatment
While treatment can prevent progression to overt hypothyroidism, it also carries risks. Overmedication can lead to hyperthyroidism, which might cause heart issues, especially in older adults. Therefore, careful monitoring of TSH levels during treatment is crucial to avoid these complications.
