Red blood may be anemia.
If the blood is red, it is probably anemia. Hemoglobin in healthy people 1000 ml blood is 12 1.6 g for men and11.5 g for women. If it is lower than this standard, it is anemia. Therefore, the lower the hemoglobin content, the heavier the anemia, and the color will change from bright red to light red. At the same time, the color of blood changes, and the general patients are accompanied by haggard face, pale face, pale lips and tongue, mental fatigue and other manifestations, which all indicate the occurrence of anemia, such as iron deficiency anemia and aplastic anemia.
Dark red blood may be hypoxia.
Dark red blood is the color of cherry, which is usually one of the manifestations of hypoxia. Generally speaking, blood receives more carbon dioxide than oxygen. With the aggravation of hypoxia, the blood color becomes darker and darker. Generally speaking, patients with emphysema and cor pulmonale may have this sign. In addition, if there is such a color change in blood, it may be a sign of gas poisoning, because the hemoglobin of people with gas poisoning combines with carbon monoxide to form carboxyhemoglobin, which loses the oxygen-carrying ability and leads to hypoxia in the body. When carboxyhemoglobin reaches 30%,
-40%, this dark red change generally occurs in the blood. In addition to the change of blood color, the color of lips, mucosa, face, chest and inner thigh skin is also a sign of gas poisoning.
White blood indicates excessive fat.
Blood is milky white and dirty, which usually means that the content of fat and protein in blood is too high. In medicine, this blood color is also called "chylous blood". For the human body, fat is just like a car needs gasoline to run. Fat is transported to all parts of the body through lipoproteins in the body to provide energy demand or store it for later use. However, too much fat can also produce unhealthy factors, and even lead to other types of diseases, such as hyperlipidemia and fatty liver, which often plague the healthy life of modern people, and are closely related to the excessive intake of foods containing high fat and high protein such as fat, eggs and milk. In addition, the bloody milky white phenomenon may also be a sign of diabetes or arteriosclerosis, so it is necessary to adjust diet and actively treat it in order to achieve the purpose of rehabilitation.
Dark purple blood may be a lung disease.
Blood is dark purple, which is usually a sign of lack of oxygen in the body. Generally speaking, when the contents of oxygen and hemoglobin in blood decrease and the reduced hemoglobin rises to more than 5 grams in 100 ml of blood, the blood will turn dark purple. Generally, this situation indicates that the patient has severe emphysema, cor pulmonale or cyanotic congenital heart disease. Must be treated as soon as possible.
Brown and black blood may be food poisoning.
Blood is brown-black, which may be due to eating food containing nitrite by mistake, such as pickled meat products with high nitrate or nitrite content, pickled vegetables and spoiled vegetables, and foods mixed with "industrial salt", which may cause nitrite poisoning. Nitrite is a strong oxidant, which can oxidize ferrous iron in hemoglobin into trivalent iron, thus making it lose its oxygen-carrying function and leading to tissue hypoxia. In addition to the change of blood color, patients will also have symptoms such as headache, dizziness, fatigue, chest tightness, shortness of breath, palpitation, nausea, vomiting, abdominal pain, diarrhea and abdominal distension. In severe cases, there will be irritability, listlessness, unresponsiveness, loss of consciousness, convulsions, coma, respiratory failure and even death.
