☀️ Vitamin D Deficiency – Causes, Signs, and Treatment
Vitamin D deficiency happens when your body doesn’t have enough vitamin D to maintain healthy bones, muscles, and immune function.
🧠 Main causes
🌤️ 1. Not enough sunlight
- Vitamin D is made in skin from sun exposure
- Staying indoors or covering skin reduces production
🍽️ 2. Poor diet
Low intake of foods like:
- Fatty fish
- Egg yolks
- Fortified milk or cereals
🧬 3. Absorption problems
Conditions like:
- Gut disorders (celiac disease, Crohn’s disease)
- Liver or kidney disease
⚖️ 4. Obesity
Vitamin D gets stored in fat tissue, making it less available in the blood.
👴 5. Aging
Older adults produce less vitamin D from sunlight.
