Hypoparathyroidism may be caused by: a. Problems following surgery, an autoimmune disorder, or congenital defects b. Heavy expos
ure to UV, systemic infections, or hypersensitivity reactions c. Infection, trauma, or an autoimmune disorder d. Developmental defects, a deficient diet, or exposure to toxic chemicals
Hypoparaghyroidism occurs when thyroid gland produce little parathyroid hormone.
This is caused by:
1. Injury to the parathyroid glands during thyroid and neck surgery.
2. It is also caused by auto immune disorder. This is as a result when the body's natural defence against invading organisms starts to attack perfectly healthy tissues.
3. Congenital defects: This is as a result when infants are born without parathyroid tissue, that is ability to make thyroid glands or when the mother has hypoparathyroidism.
Dead zones are are areas of low oxygen or hypoxia. They are usually caused by nutrient pollution that leads to algae blooms, but there are other factors that contribute
