Vitamin K deficiency brain hemorrhage is a serious problem that can occur in some infants within the first few days of life. If the blood clot is large, causing compression of the brain parenchyma, the disease can be life-threatening or leave serious sequelae.

1. What is vitamin K and why is it important?

Vitamin K is a substance that the body needs to form blood clots and stop bleeding. Unfortunately, the body cannot synthesize this vitamin, but can only supplement vitamin K from food. Small amounts of vitamin K are also made by symbiotic bacteria in the gut.
For infants, when born, the body only has a very small amount of vitamin K stored. This can lead to serious bleeding problems if vitamin K is not taken in time. In particular, of particular concern is the risk of cerebral hemorrhage due to vitamin K deficiency.

2. What is a brain hemorrhage due to vitamin K deficiency?

Hemorrhagic stroke is when blood escapes from a blood vessel and flows into the skull. Because this is inherently an enclosed space, the amount of blood flowing out will risk compressing the brain parenchyma, causing necrosis, leading to organ dysfunction or even death.
In young children, especially infants, the cause of brain hemorrhage due to vitamin K deficiency is quite common. Due to the inherently low vitamin K reserves, newborns cannot stop bleeding because the blood does not have enough Vitamin K to form blood clots. Spontaneous bleeding can occur in the brain as well as anywhere inside or outside the body. If blood flows into internal organs such as the brain or intestines, it is very difficult to notice compared to blood flowing outside. By the time it becomes apparent, levels have become very severe, which can lead to irreversible permanent brain damage and even death.

3. Why are babies prone to vitamin K deficiency leading to brain hemorrhage?

All infants, regardless of gender or race, are at risk for vitamin K deficiency. This is because:
At birth, the baby has very little vitamin K stored in the body because only a small amount can be passed to the fetus via the placenta from the mother. The symbiotic bacteria capable of producing vitamin K are not yet present in the intestines of infants. Breast milk contains low amounts of vitamin K, so exclusively breastfed babies won't get enough vitamin K. The risk of vitamin K deficiency is only partially reduced until the baby starts solids and is fed a variety of foods. form of conventional foods starting at 6 months of age. At the same time, when it comes to this stage, the symbiotic intestinal bacteria system will also work effectively, providing more vitamin K.

Some reports have shown that infants who do not receive vitamin K injections after birth have an 81-fold increased risk of late bleeding compared with infants who receive vitamin K injections. Infants who are exclusively breastfed. The child is prescribed certain medications, such as isoniazid or drugs to treat seizures. These medicines interfere with the way the body uses vitamin K. Children with liver disease cannot use their body's stored vitamin K. Children with diarrhea, celiac disease, or cystic fibrosis often have trouble absorbing vitamin K from foods.
