How many vitamin B deficiencies does a child have in class due to drowsiness

Children's drowsiness in class may be related to deficiencies in B vitamins such as vitamin B1, vitamin B2, vitamin B6, vitamin B9, and vitamin B12. B-complex vitamins are involved in energy metabolism and nervous system function, and their deficiency can easily lead to symptoms such as fatigue and lack of concentration.

1. Vitamin B1

Vitamin B1 deficiency may affect carbohydrate metabolism, leading to insufficient energy supply. Long term deficiency may lead to beriberi, manifested as fatigue and decreased appetite. It can be supplemented with whole grains, lean meat, beans and other foods, and if necessary, take vitamin B1 tablets according to medical advice.

2. Vitamin B2

Vitamin B2 is involved in cellular respiration and energy generation. When lacking, symptoms such as angular inflammation and photophobia may occur. Animal liver, eggs, and dairy products are rich in vitamin B2, and severe deficiencies require the use of riboflavin supplements under the guidance of a doctor.

3. Vitamin B6

Vitamin B6 helps synthesize neurotransmitters, and deficiency may lead to drowsiness and emotional fluctuations. Bananas, fish, and poultry are good sources, and pyridoxine hydrochloride tablets can be chosen for drug supplementation, but excessive amounts should be avoided.

4. Vitamin B9

Folic acid deficiency may cause anemia induced hypoxia, leading to increased fatigue. Dark green vegetables and citrus fruits are rich in folic acid. Pregnant women or those with absorption disorders should take folic acid tablets according to medical advice.

5. Vitamin B12

Vitamin B12 deficiency is common in vegetarian children and may lead to pernicious anemia and neurological dysfunction. It can be supplemented by fortified foods or mecobalamin tablets, but the cause of gastrointestinal absorption disorders should be ruled out.

It is recommended that parents regularly arrange a balanced diet for their children, ensuring intake of lean meat, fish, eggs, milk, whole grains, and fresh vegetables and fruits. Avoid long-term consumption of refined foods and reduce high-temperature frying during cooking to preserve B vitamins. If there is no improvement in symptoms after adjusting diet, or accompanied by weight loss, pale complexion, etc., it is necessary to seek medical attention promptly to check for absorption disorders or other potential diseases. Outdoor activities can be appropriately increased in daily life, and regular sleep patterns can also help improve daytime drowsiness.
