Smoking's Impact on the Spleen: Risks & Effects

Smoking harms the body in many ways. Nicotine from cigarettes is absorbed into the bloodstream and can affect how the body's organs operate. The spleen is a peripheral organ not often discussed in relation to smoking, but it is at risk of damage.

Function

• The spleen is a major body organ that filters harmful or damaged red blood cells and unwanted bacteria from the blood.

Impact

• A study conducted by the Brookhaven National Laboratory concluded that nicotine affects several major organs in the body including the spleen by reducing the amount of the enzyme monoamine oxidase B (MAO B).

Features

• MAO B is responsible for breaking down chemical compounds that cause high blood pressure. It also breaks down dietary amines and neurotransmitters, having an effect on both the body and personality.

Results

• Study results showed a reduction of up to 46 percent of MAO B in the bodies of smokers, significantly reducing their ability to remain healthy.

Considerations

• The spleen is not considered a vital organ and other peripheral organs are able to handle many of the spleen's responsibilities if necessary. However the MAO B effects of nicotine impact the entire body's ability to function.
