吸烟与头痛有一定的内在联系,可也并不是说所有的吸烟者都会引起头痛。但是,烟草中的化学成分能导致血管系统和血液学方面的病理改变而间接导致头痛。因为,烟草在燃烧中会产生烟焦油、烟碱、一氧化碳和二氧化硫,还有很多致癌物质。其中烟碱对血管的张力,血液流变学的影响是很大的,可使血液粘稠度增加,血小板凝集加剧。由于血液流变表现异常使血液高凝,又使脑血管紧张度增加,这是造成头痛的原因。再者,正常人血 There is a certain internal connection between smoking and headaches, but it does not mean that all smokers can cause headaches. However, the chemical constituents of tobacco can lead to pathological changes in the vascular system and hematology that can indirectly lead to headaches. Because tobacco produces tobacco tar, nicotine, carbon monoxide and sulfur dioxide as well as many carcinogens in the combustion process. Which nicotine on the vascular tension, blood rheology is great, can increase blood viscosity, increased platelet aggregation. Due to abnormal blood rheology of blood hypercoagulability, but also to increase cerebral vascular tension, which is the cause of headache. Again, normal blood
