How Smoking Effects the Entire Body

Smokers are more likely than nonsmokers to develop heart disease, stroke, and lung cancer. Smoking can cause cancer almost anywhere in your body:

  • Related to bladder, blood, colorectal, esophageal, laryngeal, lung, oral, throat, cervical, kidney, stomach, and pancreatic cancers.

Smoking harms nearly every organ of the body and affects a person’s overall health.

  • Smoking is a cause of rheumatoid arthritis.
  • Smoking causes general adverse effects on the body, including inflammation and decreased immune function.
  • Smoking is a cause of type 2 diabetes mellitus and can make it harder to control. The risk of developing diabetes is 30–40% higher for active smokers than nonsmoker.
  • Smoking can increase your risk for cataracts (clouding of the eye’s lens that makes it hard for you to see) and age-related macular degeneration (damage to a small spot near the center of the retina, the part of the eye needed for central vision).
  • Smoking affects the health of your teeth and gums and can cause tooth loss.
  • Smoking can affect bone health.
  • Smoking can also affect men’s sperm, which can reduce fertility and also increase risks for birth defects and miscarriage.
