Why steroids are so powerful and so dangerous if abused
Steroids are natural substances with many different effects in the human body, which begin over several days. The primary use of steroids in health care is to reduce inflammation and other disease symptoms. Steroid inhalers have an important role in reducing deaths from asthma, local steroid injections are useful in treating painful joints and ligaments. Steroid creams are used extensively to treat eczema and other inflammatory skin conditions. Steroids make the whole immune system less active, which can be very useful in illnesses where there is an immune component - a huge number. Steroids are the ultimate anti-inflammatory drugs.
However steroid use in medicine is limited by very serious side effects in the body as a whole. That is why steroids tend to be used sparingly in local preparations such as sprays and creams, which ensure maximum steroid dose where it is needed, and minimum levels in the blood stream.

Steroid skin creams for example cause thinning and weakness of the skin, while steroids also cause calcium to leak out of bones so that they weaken and fracture spontaneously. Steroids also make people feel very hungry and cause blood sugar to rise. People on steroids can gain weight and often develop a typical "moon face" as well as getting diabetes.
Another serious steroid problem is that we all need aggressive immune systems to fight infections and cancers, but steroids knock that out. People on high doses of steroids for medical reasons can die from chest infections and cancers of many kinds. We see these patterns in those who receive organ transplants, who need often need huge doses of steroids to stop the body from destroying the donated tissue. Cancers often develop, which shows us how important our white cells are in keeping us cancer-free, and how often all of us develop cancer in our daily lives. Most of us
