E-cigarette use increases your risk of heart disease and lung disorders. Smokers are up to 22 times more likely to develop lung cancer in their lifetime than non-smokers. Tobacco smoking is the primary cause of lung cancer, causing over two thirds of lung cancer deaths globally. One in five tobacco smokers will develop chronic obstructive pulmonary disease COPD in their lifetime, especially people who start smoking during their childhood and teenage years, since tobacco smoke significantly slows lung growth and development.
Smoking can exacerbate asthma in adults, restricting their activity, contributing to disability and increasing the risk of severe asthma attacks requiring emergency care. Tobacco smoking more than doubles the risk of transforming tuberculosis from a latent state to an active state, and is also known to worsen the natural progression of the disease. Just a few cigarettes a day, occasional smoking, or exposure to second-hand smoke increase the risk of heart disease.
Tobacco smokers have up to twice the risk of stroke and a fourfold increased risk of heart disease. Tobacco smoke damages the arteries of the heart, causing the build-up of plaque and development of blood clots, thereby restricting blood flow and eventually leading to heart attacks and strokes.
Use of nicotine and tobacco products increases the risk of cardiovascular disease. Smoking and smokeless tobacco use cause oral cancer, cancers of the lips, throat pharynx and larynx and oesophagus. Surgical removal of the cancerous larynx can lead to the need for tracheostomy, the creation of a hole in the neck and windpipe that allows the patient to breathe. Smokers are at a significantly higher risk of developing acute myeloid leukaemia; cancer of the nasal and paranasal sinus cavities; colorectal, kidney, liver, pancreatic, stomach or ovarian cancer; and cancer of the lower urinary tract including the bladder, ureter and renal pelvis.
Some studies have also demonstrated a link between tobacco smoking and an increased risk of breast cancer, particularly among heavy smokers and women who start smoking before their first pregnancy. Smoking is also known to increase the risk of cervical cancer in women infected with human papillomavirus. Smoking causes many eye diseases which, if left untreated, can lead to permanent vision loss.
Smokers are more likely than non-smokers to develop age-related macular degeneration, a condition that results in irreversible vision loss. Cataracts cause vision impairment, and surgery is the only option to restore vision. Some evidence suggests that smoking also causes glaucoma, a condition that increases pressure in the eye and can damage eyesight.
Lifelong tobacco smokers lose at least 10 years of life on average. With every puff of a cigarette, toxins and carcinogens are delivered to the body, at least 70 of the chemicals are known to cause cancer. The risk of developing diabetes is higher in smokers. Smoking is a risk factor for dementia, a group of disorders that result in mental decline. Women who smoke are more likely to experience painful menstruation and more severe menopausal symptoms.
Menopause occurs 1—4 years earlier in female smokers because smoking reduces the production of eggs in the ovaries, resulting in a loss of reproductive function and subsequent low estrogen levels. Tobacco use restricts blood flow which, if left untreated, can lead to gangrene death of body tissue and amputation of affected areas.
Tobacco use increases the risk of periodontal disease, a chronic inflammatory disease that wears away at the gums and destroys the jawbone, leading to tooth loss. Tobacco smokers are at significantly higher risk than non-smokers for post-surgical complications.
Tobacco smokers are harder to wean off mechanical ventilation. This often lengthens their intensive care unit ICU and overall hospital stay, potentially exposing them to other infection. Smokers are likely to experience gastrointestinal disorders, such as stomach ulcers, inflammatory bowel disease, associated with abdominal cramps, persistent diarrhea, fever and rectal bleeding, and cancers of the gastrointestinal tract.
Smokers are more likely to lose bone density, fracture more easily and experience serious complications, such as delayed healing or failure to heal. Components of tobacco smoke weaken the immune system, putting smokers at risk of pulmonary infections. Smoking also puts immune-compromised individuals, such as those living with cystic fibrosis, multiple sclerosis or cancer, at a higher risk of disease-related comorbidities and premature death.
Among HIV-positive smokers, the average length of life lost is Better breathing can mean better sleep at your house: Not only are smokers more likely to snore, so are non-smokers who breathe secondhand smoke on a daily basis.
