Initial symptoms of scurvy?

summary

Scurvy is a common symptom of vitamin C deficiency for a long time. However, in northern pastoral areas where vegetables and fruits are scarce, or in cities and townships where supplementary food supplement is neglected, especially in rural remote areas, scurvy is still caused by improper feeding. Since Pauling published the relationship between cold and vitamin C in 1970, many scholars have paid attention to the function of vitamin C in vivo and its high-dose clinical application. Initial symptoms of scurvy? Let's talk about it

Initial symptoms of scurvy?

Artificial feeding infants did not add complementary foods containing vitamin C, or the diet of lactating mothers was lack of fresh vegetables or fruits, or the lactating mothers were used to eating only pickles. The age of onset of scurvy (3-18 months), combined with some non-specific symptoms and feeding history, can provide clues for early diagnosis of scurvy. If the disease has developed to a certain stage or late stage, it can be diagnosed according to the symptoms of limb swelling and pain, frog shaped legs, gingival and submucosal bleeding.

Before the onset of the disease, most patients had weight loss, limb weakness, weakness, muscle and joint pain. The clinical manifestations of vitamin C deficiency in adults and infants are somewhat different. In addition to the above symptoms, adult patients have early gingival swelling, occasionally infection and inflammation. Infants have restlessness, limb movement pain, expansion of costochondral junction, swelling of long bone end of limbs (especially the lower end of femur, but does not extend forward to the joint) and bleeding tendency.

In addition, bleeding, especially massive skin bleeding, is more common in adults than in infants; The periepiphyseal hemorrhage in infants is not easy to be seen in adults. Perifollicular hyperemia is more common in adults, but not in infants. As for subperiosteal hemorrhage, skin bleeding and gingival bleeding, both adults and infants can occur. The incidence of infant is usually 6 months to 1 year old, and it can also occur at other times; Most adults suffer from vitamin C deficiency for a long time.

matters needing attention

Vitamin C is very soluble in water; It is very sensitive to oxygen, especially in the presence of iron and copper ions, it is more easily destroyed by oxidation and unstable to alkali, but it is quite stable under acidic conditions. Therefore, when cooking vegetables, you should wash them first and then cut them, then stir fry them, and try to shorten the exposure time in the air.
