Vitamin D deficiency is a prevalent concern that affects various aspects of health, particularly bone strength and muscle function. It is most common in individuals over the age of 65 and those with darker skin. However, it is preventable and treatable.
Understanding the causes of vitamin D deficiency can help you better prevent and manage this condition.
What causes vitamin D deficiency?
Here is a detailed look at the common vitamin D deficiency reasons —
- Insufficient sunlight exposure: Vitamin D synthesis in the skin is triggered by sunlight, specifically UV rays. Limited exposure due to indoor lifestyles, geographical location and seasonal changes can lead to vitamin D deficiency.
- Dietary deficiency: Very few foods naturally contain significant amounts of vitamin D. While fortified foods and supplements can help, failure to consume them adequately is one of the main causes of insufficient vitamin D.
- Health conditions: Various medical conditions can impair your body's ability to absorb or process vitamin D. Such conditions can be the reason for vitamin D deficiency, including:
- Digestive tract conditions: Crohn's disease, celiac disease and cystic fibrosis.
- Obesity: High body fat levels can sequester vitamin D and limit its availability in the bloodstream.
- Kidney and liver diseases: Conditions affecting these organs can prevent them from converting vitamin D into its active form.
- Surgical interventions: Procedures like gastric bypass surgery impact the digestive system's structure and function, potentially reducing the absorption of vitamin D.
- Medications: Certain medications are also vitamin D depletion causes. These include —
- Laxatives and steroids such as Prednisone: These can diminish calcium absorption and indirectly affect vitamin D status.
- Cholesterol-lowering drugs such as Cholestyramine and Colestipol: These interfere with vitamin D absorption.
- Seizure-preventing drugs such as Phenobarbital and Phenytoin: These can inhibit the liver's ability to activate vitamin D.
- Rifampin (a tuberculosis drug) and Orlistat (a weight-loss drug): These can reduce vitamin D levels through various mechanisms.
Conclusion
Vitamin D deficiency does not have to be a permanent state. You can make sure that your body receives an ample supply of this essential nutrient when you understand the reason for the lack of vitamin D and take proactive measures. Having reliable health insurance can also play a crucial role here. It can cover the costs of regular health screenings and necessary treatments.
