The man smoking prone to diabetes
Tobacco incomplete combustion will produce toxic, harmful substances, mainly nicotine, tar, carbon monoxide, on one hand it can destroy the human body organ, such as the pancreas regulate blood sugar, when the pancreas function after injury, the insulin secreting function will be weakened, thereby increasing the risk of diabetes mellitus. On the other hand, tobacco has a natural component, called the nornicotine, will make the blood vessel contraction, spasm, blood supply decrease, make tissue ischemia, hypoxia, at the same time, it will also stimulate the secretion of adrenaline, resulting in elevated blood sugar, damage the stability of blood sugar. Smoking can increase the risk of diabetes complications, especially cardiovascular and other fatal diseases. High density lipoprotein cholesterol in the body can cause the vasodilatation, inhibition of platelet aggregation, protecting vascular, is to protect the vessels of the good cholesterol. Smoking can make high density lipoprotein cholesterol. At the same time, smoking will also make the low density lipoprotein cholesterol, which makes it easy to oxidation, oxidized low density lipoprotein is the main material of vascular injury. Study shows, long-term smoking is easy to damage caused by the “bad cholesterol” rise to vascular, vasoconstriction, the pipe wall thickness, luminal stenosis, blood flow is slow, cause vascular spasm, blood viscosity increases, causing tissue hypoxia ischemia, increased risk of cardiovascular and microvascular disease in patients with diabetes mellitus suffer, let “one disaster after another” pain. The most common is the diabetic microvascular disease, caused by microvascular and macrovascular thrombosis, retinopathy, decreased visual acuity, diabetic nephropathy, diabetic foot disease.
