Vitamin D poisoning is one of the iatrogenic diseases. It is mainly due to the misdiagnosis and excessive use of vitamin D preparations in the prevention and treatment of rickets, such as cod liver oil, vitamin D2 (ossitol), vitamin D2 (cholecalciferol or choleretin) and vitamin D colloidal calcium. The symptoms of vitamin D poisoning now tell us.

Symptoms of vitamin D poisoning

When the body ingests a large amount of vitamin D, the feedback function of vitamin D in the body is out of balance, the intestinal absorption of calcium and phosphorus increases, and the blood calcium concentration is too high. Calcitonin regulates the deposition of blood calcium in bone and other organs, affecting its function. For example, the deposition of calcium salt in the kidney can produce tubular necrosis and renal calcification, and in severe cases, renal atrophy and chronic renal function damage can occur; Calcium deposits in the bronchioles and alveoli, damage the airway epithelial cells, cause ulcers, or calcification; If there are more calcification in nervous system, cardiovascular and other important organs, it can cause irreversible serious damage.

Common symptoms: loss of appetite, even anorexia, irritability, crying, low spirit, low fever, sweating, nausea, vomiting, diarrhea or constipation, gradually appear thirsty, frequent urination, nocturia, occasionally dehydration and acidosis

The earliest symptom is loss of appetite, even anorexia, irritability, crying, low spirit, more low fever.

Older children can report headache, blood pressure can rise or fall, heart can be heard and systolic murmur, ECG ST segment can rise, sometimes mild anemia. Severe cases may appear depression, hypotonia, dyskinesia, even coma, convulsion, renal failure, etc. Urine specific gravity is low and fixed, urine protein is positive, cell increases, also can have tubular. Long term chronic poisoning can lead to calcification of bones, kidneys, blood vessels and skin, affect physical and intellectual development, and even cause death due to renal failure. Vitamin D poisoning in early pregnancy can cause fetal malformation.

matters needing attention

Animal products cod liver oil and animal liver products such as sardine, shark, animal liver and egg yolk are reduced as far as possible. In every 100 grams of food, calcium content of more than 300 mg of food contains kelp, laver, Nostoc, black fungus and black sesame. Some calcium content is even up to 1000 Mg, and the calcium content of milk is only at medium level. It contains about 100 mg of calcium per 100 g. But the body is easy to absorb. Soybean milk can be used instead of milk to reduce calcium intake. Don't ban your mouth too much, which will lead to malnutrition.
