Posts Tagged ‘Anabolic Steroids’

Here is a “dog bites man” story from researchers at Columbia University Medical Center and Massachusetts General Hospital.

It is no secret that anabolic steroids have all sorts of nasty side effects.

Anabolic steroids can cause many adverse effects. Most of these side effects are dose-dependent, the most common being elevated blood pressure, especially in those with pre-existing hypertension, and harmful changes in cholesterol levels: some steroids cause an increase in LDL cholesterol and a decrease in HDL cholesterol. Anabolic steroids have been shown to alter fasting blood sugar and glucose tolerance tests. Anabolic steroids such as testosterone also increase the risk of cardiovascular disease or coronary artery disease. Acne is fairly common among anabolic steroid users, mostly due to stimulation of the sebaceous glands by increased testosterone levels. Conversion of testosterone to dihydrotestosterone (DHT) can accelerate the rate of premature baldness for males who are genetically predisposed, but testosterone itself can produce baldness in females.

There is a whole bunch more (we left out some of the nastier bits) where that came from. Now we can include damage to kidneys as a side effect of abusing anabolic steroids too. In fact, the damage incurred is worse than what is seen in the kidneys of morbidly obese individuals.

The investigators studied a group of 10 bodybuilders who used steroids for many years and developed protein leakage into the urine and severe reductions in kidney function. Kidney tests revealed that nine of the ten bodybuilders developed a condition called focal segmental glomerulosclerosis, a type of scarring within the kidneys. This disease typically occurs when the kidneys are overworked. The kidney damage in the bodybuilders has similarities to that seen in morbidly obese patients, but appears to be even more severe.

However, some good news also comes from this study:

When the bodybuilders discontinued steroid use their kidney abnormalities improved, with the exception of one individual with advanced kidney disease who developed end-stage kidney failure and required dialysis. Also, one of the bodybuilders started taking steroids again and suffered a relapse of severe kidney dysfunction.

If stopped in time, kidney function can improve enough for daily functioning. Kidneys in particular are so vulnerable to the effects of anabolic steroids because they are affected both directly and indirectly:

The researchers propose that extreme increases in muscle mass require the kidneys to increase their filtration rate, placing harmful levels of stress on these organs. It’s also likely that steroids have direct toxic effects on the kidneys. “Athletes who use anabolic steroids and the doctors caring for them need to be aware of the potentially serious risks to the kidney,” said Dr. Herlitz.
