- Vitamin D deficiencyAlso called calcitriol deficiency
Inadequate formation of vitamin D3 (calcitriol) in the skin of the patient (e.g. due to inadequate time in the sun), inadequate intake in food or inadequate uptake through the intestine or other causes can lead to vitamin D deficiency. Vitamin D deficiency causes reduced uptake of calcium in the intestine and increased release of calcium from the bones (secondary hyperparathyroidism). If the calcium deficiency is marked, it can lead to rickets in children or osteomalacia in adults. Because of the possible consequences, even vitamin D deficiency without symptoms is increasingly being recognised as a reason for treatment.
1. Treatment with vitamin D (calcitriol); caution because of the danger of an increase in blood calcium; 2. Calcium is usually given before vitamin treatment or as a supplement; 3. A combined formulation of vitamin D and calcium is given for mild vitamin D deficiency or for osteoporosis.
1. Possible treatment of the underlying disease; 2. Moderate solar irradiation of the skin (cf. light therapy); 3. Consumption of food which is rich in vitamin D (milk and milk products, eggs, margarine, fatty fish); 4. After treatment with vitamin D, the calcium concentration in blood serum should be regularly checked.
