What is a normal iodine level?
The iodine-replete healthy adult has about 15–20 mg of iodine, 70%–80% of which is contained in the thyroid [6]. Median urinary iodine concentrations of 100–199 mcg/L in children and adults, 150–249 mcg/L in pregnant women and >100 mcg/L in lactating women indicate iodine intakes are adequate [3].
What happens when your iodine levels are high?
High levels can inflame your thyroid gland and can cause some of the same symptoms that low levels do, including a goiter. A very large dose, like several grams of iodine at once, could put you in a coma. It also might burn your stomach, throat, or mouth, and cause a weak pulse, nausea, vomiting, and diarrhea.
What is the tolerable upper intake level for iodine?
1,100 mcg daily
UL: A Tolerable Upper Intake Level (UL) is the maximum daily dose unlikely to cause adverse side effects in the general population. The UL for iodine for adults 19+ years and pregnant and lactating women is 1,100 mcg daily.
What causes high iodine levels?
High iodine levels can be caused by dietary intake, with food high in iodine and iodized salt proving problematic; high background levels of iodine in drinking water may also cause this and exacerbate the problem of a high dietary intake.
What is the most common cause of iodine deficiency?
What is the most common cause of iodine deficiency? Pregnancy and breastfeeding put women at risk for iodine deficiency.
Can iodine make you tired?
A severe iodine deficiency may cause an abnormally slow heart rate. This could make you feel weak, fatigued, dizzy and possibly cause you to faint (26).
Does iodine make you tired?
Low iodine levels may leave you feeling tired, sluggish and weak. This is because your body needs the mineral to make energy.
What happens if you lack iodine?
GOITER – Without adequate iodine, the thyroid progressively enlarges (develops a goiter) as it tries to keep up with demand for thyroid hormone production. Worldwide, iodine deficiency is the most common cause of thyroid enlargement and goiter (see goiter brochure).
What causes low iodine?
Iodine deficiency occurs when the soil is poor in iodine, causing a low concentration in food products and insufficient iodine intake in the population. When iodine requirements are not met, the thyroid may no longer be able to synthesize sufficient amounts of thyroid hormone.
How much iodine do you need to be healthy?
The iodine-replete healthy adult has about 15–20 mg of iodine, 70%–80% of which is contained in the thyroid [6]. Median urinary iodine concentrations of 100–199 mcg/L in children and adults, 150–249 mcg/L in pregnant women and >100 mcg/L in lactating women indicate iodine intakes are adequate [3].
What is the half-life of Iodine-130?
Iodine fission-produced isotopes not discussed above (iodine-128, iodine-130, iodine-132, and iodine-133) have half-lives of several hours or minutes, rendering them almost useless in other applicable areas. Those mentioned are neutron-rich and undergo beta decay to isotopes of xenon.
How many isotopes of iodine are there?
There are 37 known isotopes of iodine (53I) from 108I to 144I; all undergo radioactive decay except 127I, which is stable. Iodine is thus a monoisotopic element.
What is the density of iodine?
In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Iodine is [Kr] 4d10 5s2 5p5. Possible oxidation states are +1,5,7/-1. Density of Iodine is 4.94g/cm3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume.
