Q. Can untreated thyroid cause death?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Untreated thyroid disorders, particularly severe cases of hypothyroidism or hyperthyroidism, can potentially lead to serious complications that, in rare cases, could result in death. However, it's important to emphasize that death directly caused by untreated thyroid disorders is extremely rare in developed countries where medical care is readily accessible.
Here are some ways in which untreated thyroid disorders can lead to severe complications:
1. Myxedema coma: This is a rare but life-threatening complication of severe untreated hypothyroidism. It occurs when hypothyroidism becomes extremely severe, leading to decreased mental function, decreased body temperature, respiratory depression, and sometimes cardiovascular collapse. Myxedema coma requires immediate medical attention and intensive care treatment.
2. Thyroid storm: This is a rare but severe complication of untreated or poorly controlled hyperthyroidism. It involves a sudden and extreme increase in thyroid hormone levels, leading to symptoms such as rapid heartbeat, high fever, confusion, agitation, and sometimes organ failure. Thyroid storm is a medical emergency that requires immediate treatment in a hospital setting.
3. Cardiovascular complications: Both untreated hypothyroidism and hyperthyroidism can increase the risk of cardiovascular problems such as heart disease, high blood pressure, and arrhythmias (irregular heart rhythms). Over time, these complications can contribute to an increased risk of heart attack or stroke, which could potentially be fatal if left untreated.
Other complications: Untreated thyroid disorders can also lead to other complications such as infertility, mental health issues (including depression and anxiety), and metabolic disturbances that may impact overall health and well-being.
While these complications are serious, it's important to remember that they are rare and typically occur in cases of severe, long-standing untreated thyroid disorders. Most individuals with thyroid disorders can effectively manage their condition with appropriate medical care, lifestyle modifications, and regular monitoring, thus reducing the risk of complications and ensuring long-term health and well-being.
