Causes & Symptoms of Iodine Deficiency

Indine Deficiency causes symptoms

Among the micronutrients, Iodine is a very important mineral which is necessary to maintain our health.
The recommended dietary allowance of this mineral is around 90mg to 110mg, based on different age groups. If the intake of iodine is less than this, then it is a deficiency.
The reasons for deficiency are either low intake of iodine or low absorption of iodine by the body. When an individual has stopped including iodine rich foods in his diet, or when the individual is having enough amounts of iodine but the body is not absorbing it for physiological purposes, these both cases lead to iodine deficiency. Loss of iodine through urine is the first indication of iodine deficiency in the latter case.
If an individual is discovered with iodine deficiency, it can lead to following health complications which are the signs and symptoms that should be paid attention to;

  • The blood pressure levels are the first parameters which will get fluctuated with insufficient amounts of iodine. Individuals with high blood pressure are known to have an iodine deficiency.
  • Thyroid glands take a lot of affects, because of iodine deficiency. Goitre and Cretinism are the two main results of iodine deficiency. Goitre: Low amounts of iodine will trigger the release of ‘Thyroid stimulating hormone’ in excess amounts, which results in the swelling of the thyroid gland or Goitre. Cretinism: Stunted body and mental retardation are some characteristics of iodine deficiency. This is predominantly observed in children, however, memory lapse, deafness, etc. are developed due to iodine deficiency in later stages of life as well.
  • Water and electrolyte balance gets disrupted with insufficient amounts of iodine in blood.

Prolonged deficiency can lead to thyroid disorders, mental disabilities, problems in reproduction, hypertension, etc. issues which can complicate the life at a greater level.
So, pay attention to your iodine levels and diet. The major iodine sources are salt, that we use regularly in our meals. Followed by green leafy vegetables, seafood, milk & it’s products.
Include them in your diet regularly and stay away from Iodine deficiency. If you have any more queries or doubts regarding iodine deficiency, then feel free to write back to us at or buzz us at
