Subclinical Hypothyroidism: When To Treat Cleveland Clinic Journal Of Medicine

subclinical hypothyroid

Intraindividual variation in TSH levels is minimal, this is secondary to a unique individual setpoint in the hypothalamic-pituitary axis. This condition correlates with an increased risk of fatal and non-fatal coronary artery disease (CAD) events, congestive heart failure and fatal stroke. This activity reviews the evaluation and treatment of subclinical hypothyroidism and explains the role of the interprofessional team in improving care for patients with this condition. Levothyroxine therapy is not recommended for pregnant patients with negative thyroid peroxidase antibody and TSH within the pregnancy-specific range or less than 4 mIU/L if the reference ranges are unavailable. In one study, the average TSH value for patients whose symptoms did not improve with therapy was 4.6 mIU/L.31 An explanation for the lack of effect in this group may be that the TSH values for these patients were in the high-normal range.

One-quarter teaspoon of iodized salt or 1 cup of low-fat plain yogurt provides about 50 percent of your daily iodine needs. On the other hand, too much may lead to either hypothyroidism or hyperthyroidism. Good sources of iodine include iodized table salt, saltwater fish, dairy products, and eggs. A 2017 systematic review found that the risk of pregnancy complications was apparent in TPO-positive women with a TSH level greater than 2.5 mU/L.

However, there’s debate underway in the medical community advice about lowering the highest normal threshold.

look at thisism does not always lead to overt hypothyroidism especially if the cause is Hashimoto’s disease. Interestingly, though, women with a TSH level between 2.5 and 4 mIU/L didn’t see any reduced risk of pregnancy loss between those treated and those untreated if they had negative thyroid antibodies. Because a higher TSH level can start to produce adverse effects on the body, people with a TSH level over 10 mIU/L are generally treated. About 60% of subclinical hypothyroidism cases resolve on their own within three months.

However, if you’re not getting enough iodine in your diet, you can develop subclinical or overt hypothyroidism. While this is uncommon in the United States due to the use of iodized table salt, iodine deficiency is the most common cause of hypothyroidism worldwide. Healthcare providers disagree on whether subclinical hypothyroidism needs to be treated due to conflicting studies showing its effectiveness. Radioactive iodine or antithyroid medications may cause subclinical hypothyroidism in people who have previously undergone treatment for hyperthyroidism.

A lack of thyroid hormone during pregnancy may lead to adverse developmental outcomes, as well as complications for the pregnant person. Due to conflicting studies, there’s still a lot of debate about if they saidism should be treated. Each case and person is unique, so the best strategy is to talk to your healthcare provider about your concerns and options. If you start to experience symptoms of hypothyroidism, such as fatigue and unexplained weight gain, talk to your healthcare provider. They’ll likely order another thyroid blood test to see if you have overt hypothyroidism.
