Jod-Basedow phenomenon

Jod-Basedow phenomenon is a condition that occurs in individuals with iodine deficiency who ingest a large amount of iodine. This sudden increase in iodine intake can lead to hyperthyroidism, a condition where the thyroid gland produces too much thyroid hormone.

Causes

The Jod-Basedow phenomenon is caused by an excessive intake of iodine, especially in individuals with a pre-existing iodine deficiency. This can occur as a result of consuming iodine-rich foods, taking iodine supplements, or receiving iodine-based contrast agents for medical imaging.

Symptoms

The symptoms of the Jod-Basedow phenomenon are similar to those of hyperthyroidism and may include:

• Weight loss
• Increased heart rate
• Tremors
• Anxiety
• Insomnia
• Heat intolerance
• Sweating
• Diarrhea

Diagnosis

The diagnosis of the Jod-Basedow phenomenon is based on the patient's medical history, physical examination, and laboratory tests. The laboratory tests may include blood tests to measure the levels of thyroid hormones and iodine in the body.

Treatment

The treatment of the Jod-Basedow phenomenon involves discontinuing the intake of excess iodine and treating the symptoms of hyperthyroidism. This may include medications to reduce the production of thyroid hormones and to manage the symptoms.
