summary

People need calcium, especially the elderly and children. In daily life, people all know that cod liver oil is good for eyes and can supplement calcium, so many people think it doesn't matter if they eat too much. But we all neglect a problem, that is, cod liver oil is toxic, so what are the symptoms of cod liver oil poisoning? Let's talk about it.

What symptom is infantile cod liver oil poisoning?

The main components of cod liver oil are vitamin A and vitamin D. Vitamin A can maintain normal vision and prevent night blindness and dry eye. However, vitamin A is not the more the better. If the elderly take vitamin A for a long time, it will increase the burden on the liver and may lead to poisoning symptoms due to excessive vitamin A. However, vitamin D can not only supplement calcium, but also maintain the normal metabolism of human body. Therefore, many elderly people take cod liver oil as a tonic. In fact, it is harmful to our health.

In fact, cod liver oil can not be taken more. Excessive use of cod liver oil can also lead to poisoning, such as nausea, vomiting, loss of appetite, general weakness, low fever, headache, rash, dry skin, dry hair, etc. In addition, vitamin D in cod liver oil does contribute to the absorption of calcium, but it should not be excessive, especially in the elderly, long-term overdose will artificially increase blood calcium and easily induce urinary calculi.

However, urinary calculi refer to the calculi in the kidney, ureter, bladder and urethra, mainly in the kidney and bladder. After the formation of stones, stones in the urinary tract movement will produce spasm, injury. If the elderly use cod liver oil or cod liver oil pill to prevent osteoporosis, arteriosclerosis, coronary heart disease or eye disease, we should pay attention to the appropriate dose, not too large.

matters needing attention

1. The first is how to choose the preparation. There are two kinds of concentrated cod liver oil preparation. The ratio of vitamin A and vitamin D is 10:1, that is to say, each milliliter of concentrated cod liver oil contains 50000 units of vitamin A and 5000 units of vitamin D, 30 drops per milliliter. The physiological requirement of vitamin A is 2500-4000 units / day, while the preventive dose of vitamin D is 400-800 units / day. Due to the inappropriate proportion of the old preparation, vitamin D is still in the treatment dose, while vitamin A has been excessive. 2. In recent years, the content ratio of vitamin A and vitamin D in a new concentrated cod liver oil preparation is 3:1, which is relatively more suitable. For the elderly, when using cod liver oil to prevent and treat osteoporosis, arteriosclerosis, coronary heart disease or eye disease, if taking traditional preparations, generally, take one pill three times a day, and stop taking the medicine for one week for two weeks. At the same time, pay attention to drinking more water, increasing urine excretion and preventing calcium precipitation. 3. People with urinary calculi or weak constitution should not take cod liver oil to prevent aggravation of stone symptoms or poisoning; Healthy people should not take cod liver oil for a long time; For patients who really need to take it for a long time, it is recommended to use it under the guidance of a doctor.
