CLEVELAND -- Many athletes want to be stronger, faster, have more endurance and recover sooner from muscle fatigue. But performance enhancing drugs (PEDs) can have some serious side effects.
Anabolic steroids or testosterone can cause bone growth to stop before it is complete in a teen. The teen may not reach his or her full adult height.
It may lead to a heart attack or stroke in young people.
It can cause high blood pressure and lead to higher levels of bad cholesterol (LDL) and lower levels of good cholesterol (HDL).
It's been linked to liver disease and possibly liver cancer. The chance of these problems is higher when steroids are taken as a pill.
It's known to cause oily skin and acne as well as hair loss and emotional upheavel such as rage.
Human growth hormone, or HGH, can cause nerve, muscle or joint pain as well as fluid retention.
It may lead to numbness in the skin and increase cholesterol. It may also increase the risk of diabetes and may also contribute to the growth of cancerous tumors.
There is no scientific evidence it improves sports performance.
