Vitamin D Deficiency

As a doctor, I frequently encounter vitamin D deficiency in my patients. It is a widespread societal issue that affects all age groups. A lack of vitamin D has a significant impact on health and the immune system.

Practical Experience

Immune System:
  • Patients with low vitamin D levels are more susceptible to infections, especially respiratory illnesses.
  • During flu epidemics, vitamin D deficiency is a risk factor for more severe illness.
  • Adequate vitamin D levels are essential for proper immune cell function and regulation of inflammatory processes in the body.
Bones and Muscles:
  • In older patients, vitamin D deficiency leads to muscle weakness and an increased risk of falls.
  • In children, it can cause rickets, a disease that leads to bone deformities.
  • In postmenopausal women, vitamin D deficiency is a risk factor for osteoporosis.
Other Health Issues:
  • Low vitamin D levels are associated with an increased risk of cardiovascular diseases, diabetes, autoimmune diseases, and certain types of cancer.
  • I often see patients suffering from depression, and after measuring their vitamin D levels and introducing supplementation, their condition significantly improves.

Recommendations

I advise all patients to have their vitamin D levels checked regularly, especially in winter. It is important to note that excessive vitamin D intake can also be harmful. If there is a deficiency, taking dietary supplements is advisable. Supplement dosage should be individualized and determined by a doctor based on laboratory results.

Sources of Vitamin D

Sunlight:

The best natural source of vitamin D. However, in our geographical location, sunlight is insufficient during winter months.

Food:

Fatty fish, egg yolks, beef liver. However, food contains only limited amounts of vitamin D.

Supplements:

The most reliable way to ensure adequate vitamin D intake.

Vitamin D is crucial for health and immunity, so maintaining sufficient intake is essential.
