Low 25-hydroxyvitamin D in pregnant women

Low 25-hydroxyvitamin D should not be unfamiliar to everyone. Low 25-hydroxyvitamin D is a common rhinitis symptom, which can easily cause patient discomfort and is relatively difficult to eradicate. Therefore, patients should understand the cause of low 25-hydroxyvitamin D in Zhuzhou City, so as to avoid the occurrence of low 25-hydroxyvitamin D. What is the reason for slightly low 25-hydroxyvitamin D?

1. Insufficient direct sunlight: The vitamin D that the body needs on a daily basis is mainly obtained by using ultraviolet rays from sunlight to irradiate the skin. Factors that make children susceptible to rickets include not taking children out for outdoor activities frequently due to continuous rainy or hot weather, living in shady houses with windows closed (because glass cannot pass ultraviolet light and affects the passage of ultraviolet light), and the large number of high-rise buildings in big cities, which cause a lot of dust in the air and block the passage of ultraviolet light.

2. Insufficient vitamin D intake: The vitamin D content in milk (including breast milk and cow's milk) is very low, which cannot meet the growth needs of children. In addition, the ratio of calcium and phosphorus in milk is not good (1.2:1), which is not conducive to the digestion and absorption of calcium and phosphorus. Therefore, babies fed with milk are more likely to suffer from rickets than those fed with pure breast milk. Milk powder feeding is mostly based on high-fiber foods such as baby rice cereal and white rice porridge, because cereal foods contain a lot of phytic acid and chemical fiber, which can combine with calcium and phosphorus in the intestine to form insoluble calcium phytate, and can also affect the digestion and absorption of calcium and phosphorus.

3. Excessive growth and development: During the neonatal period, the growth and development speed is faster, the bones grow fast, and the demand for calcium is also high, so it is easy to cause deficiency. Premature babies have insufficient calcium and vitamin D reserves in their bodies, so they grow and develop faster after birth and are more susceptible to rickets. After the age of 2, the growth rate slows down and outdoor activities and games increase, so the incidence of rickets and active rickets are less. Patients with moderate to severe malnutrition are less likely to suffer from rickets due to their slow growth and development.

4. Influence of other diseases: Chronic gastrointestinal diseases can affect the absorption and utilization of vitamin D, calcium and phosphorus. The liver and kidneys are organs that hydroxylate vitamin D. When they are diseased, the hydroxylation process of vitamin D may be affected, and the absorption and utilization of calcium and phosphorus may also be affected. In addition, long-term use of phenytoin and phenobarbital drugs can promote the effect of hepatitis B antibiotics, causing the decomposition of vitamin D3 and 25-(OH)D3 to lose specificity, resulting in rickets.

Warm reminder: In this hot summer, low 25-hydroxyvitamin D has gradually harmed many groups, and many people do not quite understand the harm of low 25-hydroxyvitamin D. This often causes a lot of confusion due to momentary negligence. I think this is also one of the issues that many patients with low 25-hydroxyvitamin D need to understand.
