Vitamin D deficiency occurs when there is an insufficient level of vitamin D in the body, which is essential for maintaining healthy bones and immune function.
Common Causes:
- Limited Sun Exposure: Vitamin D is produced in the skin in response to sunlight, so lack of sun exposure can lead to deficiency.
- Dietary Insufficiency: Not consuming enough vitamin D-rich foods, such as fatty fish, fortified dairy products, and egg yolks.
- Absorption Issues: Conditions like celiac disease or Crohn's disease can affect how the body absorbs vitamin D.
Symptoms:
- Bone Pain and Weakness: Due to impaired calcium absorption.
- Muscle Weakness: Often subtle but can affect daily activities.
- Fatigue: Feeling unusually tired or lethargic.
If you suspect a deficiency, it's advisable to consult a healthcare provider for a blood test and appropriate guidance.
