What is the consequence of Vitami D deficiency ?
Vitamin D deficiency primarily weakens bones, causing rickets in children (bowed legs, growth issues) and osteomalacia/osteoporosis in adults (soft, brittle bones, fractures) due to impaired calcium absorption, leading to muscle weakness, fatigue, pain, and increased fall risk, while also potentially affecting mood, immunity, and increasing risk for chronic diseases.
Musculoskeletal Consequences
Children: Growth retardation, skeletal deformities like bowed legs (Rickets).
Adults: Osteomalacia (soft bones), osteoporosis (bone loss), increased fracture risk, bone pain, joint aches, muscle weakness, and falls.
Other Systemic Effects
Immune System: Increased susceptibility to infections.
Mental Health: Linked to fatigue, depression, anxiety, and mood swings.
Pain: Can cause chronic pain, nerve-related discomfort, and muscle twitching.
Skin & Hair: Potential hair loss, dry skin, and delayed wound healing.
Chronic Diseases: Research suggests links to hypertension, cardiovascular disease, Type 1 diabetes, and certain cancers, though more study is needed.
Key Mechanism
Insufficient Vitamin D reduces calcium absorption from the gut, leading to low blood calcium (hypocalcemia).
The body overcompensates by activating parathyroid hormone (secondary hyperparathyroidism) to pull calcium from bones, further weakening them.
Common Symptoms:-
Bone/back pain, fatigue, muscle weakness, feeling down, getting sick often, hair loss, poor sleep.
