Kaynak: https://ekonsey.com/en/diseases/vitamin-d-deficiency

Vitamin D deficiency is a common condition that can cause muscle and bone pain, fatigue, and disorders of calcium and bone metabolism.

## Content

Vitamin D is less a vitamin than a potent prohormone. It plays a critical role in almost every area of human physiology, from the regulation of calcium and phosphate metabolism and the support of the immune system to bone mineralisation and muscle function. A large part of the body's vitamin D is synthesised when sunlight reaches the skin, and the rest comes from food.Because of modern living conditions, long periods spent indoors, sunscreen use and geographical factors, vitamin D deficiency is common in the general population. At eKonsey, our Multidisciplinary Council of experienced physicians in endocrinology, metabolic diseases and nutritional medicine takes a holistic approach to resistant vitamin D deficiency, malabsorption and its hormonal consequences.Advantages of the eKonsey Multidisciplinary ApproachComprehensive Laboratory Analysis: Vitamin D levels need to be interpreted together with calcium, phosphate, PTH and ALP.Resolving Resistant Cases: In cases that do not respond to standard treatment, the underlying malabsorption or metabolic block is identified.Reliable Second Opinion: Your test results are reviewed by expert professors wherever you live, and a Medical Opinion is prepared for you.

## Common Symptoms

- Muscle and bone pain - Widespread muscle and bone pain.
- Chronic fatigue and weakness - Persistent tiredness, weakness and low energy.
- Muscle weakness - Muscle weakness felt when climbing stairs or standing up.
- Hair loss - Hair loss and brittle nails.
- Reduced immunity - Frequent illness and reduced resistance to infection.

## Causes

- Chronic and Resistant Vitamin D Deficiency - Blood 25-OH vitamin D levels remain below the reference range for a long time. When levels fail to rise despite standard supplementation, underlying metabolic or genetic factors need to be investigated.
- Secondary Hyperparathyroidism due to Vitamin D Deficiency - Long-standing vitamin D deficiency and the resulting fall in calcium absorption make the parathyroid glands overwork to keep blood calcium balanced (secondary hyperparathyroidism). Over time this can accelerate mineral loss from the bones.
- Malabsorption - Digestive disorders (coeliac disease, Crohn's disease, irritable bowel syndrome), a history of bariatric surgery, or liver or kidney dysfunction can prevent vitamin D from being absorbed from the gut or converted to its active form.

## Second Opinion

A second specialist's review of your Vitamin D Deficiency diagnosis or treatment plan can clarify your next step. On eKonsey this review is done online.
