How can smoking affect circulatory system

Effects of Smoking: Decreased circulation of blood causes hypertension, blood clots, increased heart rate, and arterial wall buildup along with lowered body temperature.

Complications due to Smoking: Smoking directly leads to coronary heart disease that is the top reason for death worlwide. Passive smoking is injurious to health: Passive smoking increases the risk of functionality of circulatory system too. Jun 13, Featured Experts. Reddy Pandurang H. Sumit Bhatia Senior Consultant —Gastroenterology. Many smokers gain weight after they quit, but the average weight gain is 10 pounds or less.

You can control weight gain by following a heart-healthy eating plan and being physically active. Remember the bright side—food smells and tastes better if you aren't smoking. Learn more about participating in a clinical trial.

Samet, M. Smoking and Your Heart. Smoking and Atherosclerosis. What Are the Risks of Smoking? For example, they: Contribute to inflammation, which may trigger plaque buildup in your arteries.

Damage blood vessel walls, making them stiff and less elastic stretchy. This damage narrows the blood vessels and contributes to the damage caused by unhealthy cholesterol levels. Disturb normal heart rhythms. Increase your blood pressure and heart rate, making your heart work harder than normal. Smoking also increases your triglyceride level.

Triglycerides are a type of fat found in the blood. Thicken your blood and make it harder for your blood to carry oxygen. Smoking and Heart Disease Risk Smoking is a major risk factor for ischemic heart disease , a condition in which plaque builds up inside the coronary arteries. Secondhand Smoke Risks Secondhand smoke is the smoke that comes from the burning end of a cigarette, cigar, or pipe.

Secondhand smoke also raises the risk of future coronary heart disease in children and teens because it: Damages heart tissues Lowers HDL cholesterol Raises blood pressure The risks of secondhand smoke are especially high for premature babies who have respiratory distress syndrome and children who have conditions such as asthma.

Cigar and Pipe Smoke Risks Researchers know less about how cigar and pipe smoke affects the heart and blood vessels than they do about cigarette smoke. What Are the Benefits of Quitting Smoking? Quitting smoking will benefit your heart and blood vessels. For example: Among persons diagnosed with coronary heart disease, quitting smoking greatly reduces the risk of recurrent heart attack and cardiovascular death. In many studies, this reduction in risk has been 50 percent or more. Heart disease risk associated with smoking begins to decrease soon after you quit, and for many people it continues to decrease over time.

Your risk of atherosclerosis and blood clots related to smoking declines over time after you quit smoking. Get Ready To Quit If you want to quit smoking, try to get motivated. Get Support Set a quit date and let those close to you know about it. Get Medicine and Use It Correctly Talk with your doctor and pharmacist about medicines and over-the-counter products that can help you quit smoking. Learn New Skills and Behaviors Try new activities to replace smoking.
