People get vitamin D through food and by exposure to sunlight. For most adults, vitamin D deficiency isn’t a concern. Some, especially those with dark skin and adults older than 65, are at higher risk of the condition.
The usual causes of Vitamin D are when it lacks in your diet when one does not get enough exposure to sunlight, when your liver or kidneys cannot convert Vitamin D to its active form or when you take medicines that interfere with your body’s ability to convert or absorb Vitamin D.
Most people have no symptoms. In severe cases, deficiency can lead to thin, brittle or misshapen bones.
Any Affecting Organs:
It can lead to a loss of bone density, which can contribute to osteoporosis and fractures.
Vitamin D supplementation is the main treatment.
