Vitamin D overdose symptoms in babies

Vitamin D is an important basic nutrient for the human body. It plays an important role in promoting the body's absorption of calcium. For infants, intake of vitamin D can prevent rickets, but it should also be noted that excessive use of vitamin D may cause more serious harm, such as affecting bone development, causing drowsiness, and polyuria in patients. Let us understand the symptoms of excessive vitamin D in infants.

Vitamin D overdose symptoms in babies

Although vitamin D plays an important role in the development of the baby's bones, brain, teeth, etc., mothers should still pay attention to the fact that vitamin supplementation should not be excessive. Babies' intake of vitamin D through diet generally does not cause poisoning, but if they consume excessive amounts of vitamin D supplements or dairy products fortified with vitamin D, there is a possibility of vitamin D overdose and poisoning.

It is now generally believed that if the daily intake of vitamin D exceeds 25 micrograms, it is possible to cause poisoning, with symptoms such as anorexia, vomiting, headache, drowsiness, diarrhea, and polyuria. Long-term excessive intake can cause arrhythmia, high blood pressure, convulsions and kidney failure.

Therefore, mothers must control their babies' vitamin D intake and not let their babies take in too much vitamin D to prevent adverse consequences.

Prevention methods

1. Understand the dosage of VitD for prevention or treatment. The preventive dosage should not exceed 400 IU per day. Parents should be informed of the dangers of excessive VitD and the medication should be used according to the doctor's orders.

2. Before emergency treatment is needed, the child should be asked in detail about the dose of VitD he or she has used in the past. Most poisoning cases occur on the basis of long-term and large-scale oral intake of cod liver oil. Symptoms of poisoning are more likely to occur after D2 or D3 injection. Therefore, it is important to understand the indications before injecting large doses.

3. If the therapeutic effect of general VitD dosage is unsatisfactory, blood calcium, phosphorus and alkaline phosphatase should be checked before deciding whether to use intensive therapy.

4. In the prevention and treatment of general nutritional rickets, try to avoid large doses of vitamin D. When large doses of vitamin D must be used for treatment, closely observe the clinical symptoms, measure blood calcium monthly for signs of poisoning, and measure once every half month if necessary.

5. Practice has shown that 20 IU of VD has the same effect as 400,000 IU. When a large dose of VitD is required for emergency treatment, it is best not to exceed 20 IU, and a second injection is generally not required. For children with normal liver, kidney and gastrointestinal function, oral administration of VitD has the same effect as intramuscular injection. Oral administration is safe and intramuscular injection is not necessary.
