Most iodine is found in fish and seafood, and in seaweed, so up your intake of these foods.
Dr Lee added: “Cow’s milk is also a good source, as it is enriched with iodine, resulting from the addition of iodine to animal feed.
“Poultry, eggs, bread, nuts, fruit, and vegetables contain small amounts of iodine.
“In the UK, iodine is not routinely added to salt, as it is in many European countries, as too much salt is harmful to blood pressure.”
Iodine deficiency results in an underactive thyroid gland, with low levels of thyroxine, also known as hypothyroidism.
Dr Lee said: “The symptoms and signs can come on very insidiously meaning it can be a long time before it is diagnosed or sometimes low thyroxine levels are discovered incidentally from a blood test.”
At other times, your doctor may be alerted that you could be hypothyroid because of various signs including the following 13 symptoms:
Weight gain
When thyroxine levels are low, your metabolic rate slows, and this is associated with weight gain.
Dr Lee pointed out that massive weight gain is unusual and it is usually only around five to 10 pounds.
Feeling weak
Because your body is releasing energy less efficiently, you feel weak and tired.
