1. VITAMIN D DEFINITION• Edward Mellanby discovered vitamin D.• Is a Fat-soluble vitamins.• Several forms of vitamin D have been discovered:
Vitamin D 2Ergocalciferol
Vitamin D 3Cholecalciferol
Vitamin D 422-dihydroergocalciferol
Vitamin D 5Sitocalciferol
2. FUNCTIONS• Vitamin D is stored in…
• Maintain levels of calcium and phosphorus normal.• Participate in cell growth and maturation.• Strengthens the immune system helping to prevent
infection.
3. MAIN SOURCES
• Vitamin D deficiency can occur when:– Daily intake is less than
the recommended levels.
– The kidney can not convert vitamin D into the active form
– sun exposure is insufficient
– Can not absorb properly at the digestive tract.
4. DEFICIENCY
• The vitamin D deficiency resulting in decreased bone mineralization, leading to soft in bone diseases such as rickets in children and osteomalacia in adults, even associated with the onset of osteoporosis.
5. RICKETS
• Is characterized by skeletal deformities.
6. SYMPTOMS• Skeletal deformities• Bowlegs• Forward projection of the
breastbone (pigeon chest)• Bumps in the rib cage
(rachitic rosary)• Skull asymmetrical or odd
shape• Spinal deformities• Dental deformities• Delayed tooth formation
7. MEDICATION• Can be treated gradually over several
months or one dose of a single day. • Based on a clinical trial found that a single
dose of 600,000 IU of vitamin D3 orally was comparable to a dose of 20,000 IU of vitamin D3 per day orally for 30 days.
• The incremental dose may be 125-250 micrograms (5.000 to 10.000 IU), which are ingested daily for two to three months.
• A single dose of one day may be 15,000 micrograms (600,000 IU) of vitamin D, which is ingested orally in 4-6 divided doses. Intramuscular injection is also an alternative for a dose of a single day.
• It is recommended that exposure to moderate amounts of sunlight.
