Symptoms And deficiency of Vitamin D

:

Common Symptoms of Vitamin D Deficiency:

Vitamin D plays a key role in calcium absorption, bone health, immune function, and more. A deficiency can lead to both subtle and serious symptoms.

In Adults:

Fatigue and Tiredness

Bone Pain (especially in lower back, legs, hips, and ribs)

Muscle Weakness or Aches

Mood Changes (depression, irritability)

Frequent Illness or Infections

Hair Thinning or Hair Loss

Impaired Wound Healing

Weight Gain (indirectly through hormonal disruption)

Loss of Bone Density → increased risk of fractures and osteoporosis

In Children:

Delayed Growth

Irritability

Soft Skull or Leg Bones (can lead to bowing of the legs)

Dental Problems

Rickets – a severe bone-softening disease

Potential Health Consequences of Long-Term Deficiency:

Osteomalacia (soft bones in adults)

Osteoporosis (brittle bones)

Increased Risk of Chronic Diseases.

  * Cardiovascular disease

  * Diabetes

  * Certain cancers (e.g., colon, breast)

  * Autoimmune diseases (e.g., multiple sclerosis)

Causes of Vitamin D Deficiency:

Limited Sun Exposure

Dark Skin (more melanin reduces Vitamin D production)

Use of Sunscreen (blocks UVB rays needed for Vitamin D synthesis)

Age (older adults synthesize less Vitamin D)

Diet Low in Vitamin D

Malabsorption (e.g., celiac disease, Crohn’s, gastric bypass)

Kidney or Liver Disorders (impair conversion to active Vitamin D)

Diagnosis:

Blood Test: 25-hydroxyvitamin D \[25(OH)D] is the best indicator.

  Deficiency: < 20 ng/mL (50 nmol/L)

  Insufficiency: 20–30 ng/mL

  Sufficiency: > 30 ng/mL

Prevention and Treatment:

Sunlight Exposure: 10–30 minutes, 2–3 times a week on face, arms, legs

Dietary Sources: Fatty fish (salmon, mackerel), fortified milk, egg yolks

Supplements: Vitamin D3 is typically recommended
