If the physiological increase in hemoglobin is triggered by newborns and highland residents, there is generally no obvious harm. If the increase is caused by pathological diseases, it may lead to respiratory difficulties, fainting, thrombosis and smooth muscle dysfunction and other hazards, seriously threatening the life of patients.
1. High hemoglobin in patients with congenital heart disease and pulmonary heart disease will lead to chest tightness, palpitations and other symptoms, and in severe cases, generalized bruising and swelling can also occur. Some patients may also manifest as dyspnea, fainting, angina, hemoptysis, etc., but also cyanosis, shock, mental disorder, irritability and other phenomena, endangering the life.
2. High hemoglobin can also lead to the formation of thrombus, where there is a serious hemolysis caused by increased hemoglobin, easy to have thrombosis. Such as recurrent abdominal pain during the course of the disease, may be related to thrombosis, visible mesenteric thrombosis, pulmonary microvascular thrombosis can lead to pulmonary hypertension; cerebral veins are most likely to be involved in sagittal sinus thrombosis, headache, eye pain, ophthalmic papilledema, hemiplegia, and so on.
3. A large amount of free hemoglobin depletes NO and causes smooth muscle dysfunction, resulting in dysphagia, esophageal spasm, abdominal pain and erectile dysfunction. The spleen is often moderately enlarged, the liver is mildly or moderately enlarged, and bile pigment stones are formed in a few cases due to long-term massive hemolysis.
It is recommended that patients with high hemoglobin, actively seek medical attention, first exclude physiological factors, if it is due to disease, need to be actively treated to avoid serious harm.
