Types of disease cause by tobcco?
1. Cardiovascular diseases:
- Coronary heart disease (CHD): Smoking cigarettes damages the heart and blood vessels, leading to the buildup of plaque in the arteries (atherosclerosis). This plaque can narrow the arteries and reduce blood flow to the heart, which can cause chest pain (angina), heart attacks, and strokes.
2. Respiratory diseases:
- Chronic obstructive pulmonary disease (COPD): COPD is a group of progressive lung diseases that includes bronchitis, emphysema, and chronic asthma. Smoking is the leading cause of COPD, which causes inflammation and damage to the lungs, leading to shortness of breath, wheezing, chest tightness, and coughing.
3. Cancers:
- Lung cancer: Smoking cigarettes is the leading cause of preventable cancer deaths in the United States. Cigarette smoke contains over 4,000 chemicals, many of which are known carcinogens. These chemicals damage the DNA in lung cells, leading to the development of lung cancer.
4. Oral diseases:
- Gum disease: Smoking cigarettes can cause gum disease (periodontitis), which is a serious infection of the gum tissue and bone that support the teeth. Gum disease can lead to bleeding, pain, and tooth loss.
5. Pregnancy complications:
- Premature birth (less than 37 weeks of pregnancy): Smoking during pregnancy increases the risk of premature birth, which is a leading cause of infant mortality and long-term health problems.
6. Sudden infant death syndrome (SIDS):
- Smoking during pregnancy or being exposed to secondhand smoke after birth increases the risk of SIDS, the leading cause of death for infants aged 1 month to 1 year.
7. Other diseases:
- Peripheral artery disease (PAD): Smoking cigarettes can increase the risk of PAD, a condition in which the arteries in the arms and legs become narrowed or blocked, limiting blood flow. PAD can cause pain, numbness, and weakness in the affected limbs, and can lead to amputation.
- Stroke: Smoking cigarettes increases the risk of stroke, the sudden loss of brain function caused by a blockage or rupture of an artery in the brain.
- Cataracts: Smoking cigarettes may increase the risk of developing cataracts, a clouding of the lens in the eye that leads to impaired vision.
- Erectile dysfunction (ED): Smoking cigarettes can damage blood vessels, including those that supply the penis, which can lead to ED, the inability to achieve or maintain an erection.
