Vitamin D deficiency (Hypovitaminosis D)

post-30

Vitamin D is known as “sunshine vitamin”because our body produce it when we are exposed to sunlight. But we also can obtain it from foods such as some fish, fish liver oils, and egg yolks and in fortified dairy and grain products.

Importance of Vitamin D

The main function of Vitamin D is that it promotes the proper growth of bones and muscles. It is very important as it helps to absorb calcium from the diet. Calcium is required for the body for proper functioning of heart, muscles, nerves and clotting of blood. Studies have shown deficiency of calcium is associated with low bone mass and high fracture rates.

Vitamin D is essential for production of hormone called calcitriol (known as active vitamin D). Insufficient amount of calcitriol leads to insufficient calcium absorption from the diet. In such situation body takes calcium store from the skeleton of the bones causing weakening of bones and also prevent further formation of strong bones.

Vitamin D deficiency

The medical term for vitamin D deficiency is called Hypovitaminosis D. Vitamin D deficiency or Hypovitaminosis D is common in people with cardiovascular disease. Studies have shown almost all people with heart failure has reduced levels of vitamin D.

Researchers believe that vitamin D plays important role in prevention and treatment of a number of different conditions such as type 1 and type 2 diabetes,hypertension, glucose intolerance and multiple sclerosis.

More amount of melanin pigment in skin which reduces the skin ability to makevitamin D

Malnutrition especially in children that leads to rickets  

Inabilityof kidney to convert vitamin D to its active form

Inability of digestive system to absorb vitamin D due to medical problems like Crohn’sdisease, cystic fibrosis and celiac disease

Obesityproblem which causes extraction of vitamin D from body by fat cells alteringits releases into blood circulation

Symptoms and health risks associated with vitamin Ddeficiency

Weak bones and muscles aches

Osteomalaciain adults which is characterized by muscle weakness and bone fragility

Ricketsin children which is characterized by impeded growth and deformity in bones

Osteoporosis characterized by reduced bone mineral density and bone fragility

Fractures in bones and spinal deformities.

Depression

Weightgain

Increased risk of cardiovascular disease, heart stroke

Cognitive impairment in older adults

Severe asthma in children
