Vitamin C is a necessary vitamin for human body. If we lack vitamin, it will cause damage to our body. So what does it mean that your body lacks vitamin C?
How does vitamin C deficiency cause
The disease caused by vitamin C deficiency is scurvy. It is common in children and has a slow onset. The main manifestations are gum swelling, congestion, bleeding, skin ecchymosis, limb pain, weakness and fatigue, and anemia. Bone changes in children.
It is common in northern China and occurs in winter and spring. Vitamin C is also called ascorbic acid (ascorbic acid or ascorbate). Due to the lack of gulose lactone oxidase in human body, gulose lactone (a-one-l-gulose lactone) cannot be converted into L-ascorbic acid. Therefore, the human body cannot synthesize ascorbic acid, and vitamin C needs to be often supplied from food.
Etiology of vitamin C deficiency
1. Insufficient intake
Human milk contains 227 ~ 400 & mu; Mol / L vitamin C, so breastfed infants are generally not easy to get sick. However, if the lactating mother lacks vitamin C in the diet for a long time, the insufficient content of breast milk can also make the infant sick. The content of vitamin C in raw milk was only 85 & mu; Mol / L and destroyed after boiling.
Vitamin C mainly exists in fresh fruits and green leafy vegetables, because of the lack of fruits and vegetables, or in industrialized cities, because of the neglect of food, the lack of fruits and vegetables may lead to the lack of vitamin C.
2. Absorption barrier
Long term digestive dysfunction can affect the absorption and utilization of vitamin C.
3. Increased demand
During the acceleration of growth and development, febrile diseases and wound healing, the demand for vitamin C increases. If the intake is insufficient, deficiency can occur.
clinical manifestation
1. Systemic symptoms
Vitamin C stored in the body at birth can generally be used for 3 months after birth, so vitamin C deficiency is more common in infants over 6 months. Slow onset, pale complexion, loss of appetite, weakness of limbs, irritability, no weight gain or loss, vomiting, diarrhea, etc. But it is usually not easy to be detected by the caregiver.
2. Bleeding performance
Due to the decrease of collagen fibers and the increase of brittleness in the capillary wall, ecchymosis and ecchymosis appear in the whole body skin, which are found on the skin of limbs, especially in the knee and ankle. Severe vitamin D deficiency of muscles, organs and mucous membranes can also be such as bleeding, bleeding, hematuria, blood in stool, intra-articular and intracranial bleeding.
3. Bone changes
Infants are prone to subperiosteal hemorrhage, and slight activities can cause severe pain. If the lesion is near the knee and ankle, the joint is swollen but not red, the two thighs are abducted, the lower leg is bent inward, like to maintain the frog leg posture, unwilling to move, showing pseudoparalysis;
If it occurs at the junction of rib and costal cartilage, it is obviously prominent and smaller, forming scurvy beads. Due to the subluxation of sternal plate at the junction of rib and costal cartilage, the depression can be touched on the inner side of the raised beads, while the rickets beads are symmetrical and blunt due to the widening of cartilage epiphysis, and there is no depression on the inner side. Because of pain when moving ribs, children have shallow breathing speed. Wound healing slows down.
4. Gingivitis
Gingival swelling, bleeding, infection and ulcer, tooth loosening and growth disorder.
5. Others
Often associated with infection, malnutrition and other vitamin deficiencies.
Treatment of vitamin C deficiency
The specific treatment for scurvy is the use of vitamin C.
Severe
Vitamin C500 ~ 1000mg / D is injected intravenously for 4 ~ 5 days, and then taken orally for 300 ~ 500mg / D for 2 ~ 4 weeks. Later, it can be supplemented with food or supplementary food.
Mild disease
Vitamin C100 ~ 300mg / D is taken orally. Generally, it should be treated continuously for 2 ~ 3 weeks.
Diagnostic treatment
The suspected cases were given vitamin C50 ~ loomg / D orally for 1-3 weeks; Infants with megaloblastic anemia should be given vitamin C50 ~ loomg / D and folic acid at the same time; Those with gingival bleeding should keep their mouth clean; To prevent fracture and epiphyseal dislocation, keep quiet and move less. Don't do too much examination.
It is also indispensable to correct bleeding, prevent infection, pay attention to rest and supplement a variety of vitamins and nutrients. After treatment, local pain and tenderness decreased in 1-2 days, appetite improved, lower limbs could move after 4-5 days, symptoms disappeared in 7-10 days, weight gradually increased, local tenderness disappeared in about 3 weeks, and capillary fragility returned to normal. The recovery time of bone lesions and subperiosteal hematoma is long, which often takes several months, but no deformity is left.
Conclusion: through the above description of this article, I believe you also have some understanding of the above introduction. Yes, you still have to pay more attention to our health. Only a healthy body is the driving force for us to live. It must not be possible without a good body. For our health, We still have to supplement trace elements in time.
