Question

iodine is a trace mineral necessary for thyroid function. possible consequences of iodine deficiency include which of the following?
check all that apply
goiter
dermatitis
megaloblastic anemia
delayed intellectual development
crohns disease
stunted growth

Explanation:

• Goiter: Iodine is needed for thyroid hormone production. Deficiency causes the thyroid to enlarge (goiter) as it tries to produce hormones.
• Delayed intellectual development: In children, iodine deficiency (especially during development) can lead to cognitive delays due to thyroid hormone's role in brain development.
• Stunted growth: Thyroid hormones (dependent on iodine) are essential for growth; deficiency can impair growth.
• Dermatitis: Related to skin inflammation, not iodine deficiency.
• Megaloblastic anemia: Caused by B12/folate deficiency, not iodine.
• Crohn’s disease: Inflammatory bowel disease, unrelated to iodine.

Answer:

• Goiter
• Delayed intellectual development
• Stunted growth
