What are the symptoms of iodine deficiency?
A goitre is often a sign of deficiency in iodine, but several other warning signs may point to the condition too.
According to Temple Health, these may include:
- Weight gain, fatigue and weakness
- Thinning hair
- Dry skin
- Feeling colder than usual
- Slowed heart rate
If a doctor suspects these symptoms signal an iodine insufficiency, they may conduct a physical examination and urine test, or a blood test.
When a diagnosis is made, it is often followed by dietary or supplement recommendations, depending on the severity of the condition.
