Blue-red complexion

Introduction Cyanosis may be caused by histamine poisoning caused by fish. Since animals such as shrimp, crab, and squid die, the protein in the body rapidly decomposes, producing a large amount of histamine. Eating these aquatic products will increase the histamine content in the human blood. If you eat improperly or allergic to the face or even the skin color, it will appear blue-red, discomfort, and sometimes accompanied by headache and itching. Eating too long a fish, too much histamine into the blood. Fish with red skin (such as squid, squid, fish ginseng, saury, sardines, horse mackerel, tuna, etc.) have more hemoglobin in the muscles, so the histidine content is also higher, when it is rich in histamine After acid decarboxylase-producing bacteria (such as Proteus mirabilis, A. faecalis, Escherichia coli, Streptococcus, Staphylococcus, etc.) are contaminated, the histidine in the fish meat can be decarboxylated to form histamine.

Cause

Eating too long a fish, too much histamine into the blood. Fish with red skin (such as squid, squid, fish ginseng, saury, sardines, horse mackerel, tuna, etc.) have more hemoglobin in the muscles, so the histidine content is also higher, when it is rich in histamine After acid decarboxylase-producing bacteria (such as Proteus mirabilis, A. faecalis, Escherichia coli, Streptococcus, Staphylococcus, etc.) are contaminated, the histidine in the fish meat can be decarboxylated to form histamine. Other amino acid decarboxylation products such as cadaverine, putrescine, melamine, aminohexanol, etc., can synergize with histamine to enhance toxicity.

After eating the fish, the skin is blue-red and the body is uncomfortable, sometimes accompanied by headaches and itching.

When the histamine content in the fish reaches 4mg / gram, it can cause poisoning. When the human body ingests histamine up to 100 mg or more, it is prone to poisoning, and it is also related to the allergic nature of the individual's constitution.

Differential diagnosis

Differential diagnosis of cyan complexion:

Blush complexion: may be caused by excessive consumption of lychee. This is because litchi has high fructose content. After a large amount of consumption, the glucose invertase in the liver is not as good as converting fructose into glucose, causing a large amount of fructose to accumulate in the blood and causing skin color changes, which may cause discomfort.

Facial flushing: Many people's facial flushing is caused by drinking. Even if the alcohol concentration is not high, drinking alcohol will not occur. In addition to the face, it can also extend to the neck, trunk and limbs, sometimes accompanied by wheal and itching, affecting work and rest, which is caused by alcohol-induced irritation and allergies. People with this kind of reaction should drink less alcohol or stop drinking.

Red complexion: May be caused by histamine in food. Since animals such as shrimp, crab, and squid die, the protein in the body rapidly decomposes, producing a large amount of histamine. Eating these aquatic products will increase the histamine content in the human blood. If you eat improperly or allergic to the face or even the skin color, it will appear blue-red, discomfort, and sometimes accompanied by headache and itching.

Make-up red complexion: refers to redness on the cheeks, mostly caused by excessive intake of animal fat and protein. After eating the fish, the skin is blue-red and the body is uncomfortable, sometimes accompanied by headaches and itching. When the histamine content in the fish reaches 4mg / gram, it can cause poisoning. When the human body ingests histamine up to 100 mg or more, it is prone to poisoning, and it is also related to the allergic nature of the individual's constitution.
