In the 'Symptoms - Food - Intake' section of our in-depth questionnaire we ask the following question about iodine consumption:
 
Estimate how often you consume iodine-containing food. The most common dietary sources of iodine are seaweeds and iodized salt.

 

Your answer  

...indicates  

...and suggests
1.   "Don't know"      
2.   "Never / rarely / I don't make a point of it"    Low iodine consumption   A risk factor
3.   "A few times per week"    Some iodine consumption   A risk factor
4.   "Daily or almost daily"    High iodine consumption   A risk factor


Your answer will affect the likelihoods of the conditions below.  Any answers in green reduce the likelihood of the condition.

GLOSSARY

Cancer
Refers to the various types of malignant neoplasms that contain cells growing out of control and invading adjacent tissues, which may metastasize to distant tissues.

Hyperthyroidism (Hyperthyroid)
An abnormal condition of the thyroid gland resulting in excessive secretion of thyroid hormones characterized by an increased metabolism and weight loss.

Hypothyroidism (Hypothyroid)
Diminished production of thyroid hormone, leading to low metabolic rate, tendency to gain weight, and sleepiness.

Iodine
A essential mineral that is an integral part of the thyroid hormones, thyroxin and triiodothyronine which have important metabolic roles and govern basal metabolism. The best known iodine deficiency symptom is goiter. Other iodine deficiency problems are reduced vitality, hypothyroidism, inability to think clearly, low resistance to infection, loss of control of the muscles of the mouth resulting in mouth contortion and drooling, defective teeth, tendency to obesity and cretinism which is a congenital abnormal condition marked by physical stunting and mental deficiency.

Thyroid (Thyroid Gland)
The thyroid gland is an organ with many veins, anchored around the front of the throat near the voice box. It is essential to normal body growth in infancy and childhood. It absorbs iodine from the diet and releases thyroid hormones - iodine-containing compounds that help govern the rate of the body's metabolism (its total life processes), affecting body temperature, and regulating protein, fat and carbohydrate catabolism in all cells. They keep up growth hormone release, skeletal maturation, and heart rate, force, and output. They promote central nervous system growth, stimulate the making of many enzymes, and are necessary for muscle tone and vigor. To a high degree, metabolism is regulated by the hormone thyroxine, which can be made by the thyroid if enough organic iodine is available. An enlarged thyroid gland that is not cancer is sometimes called goitre.
