The gym mirror rarely tells the whole story. Behind toned bodies and impressive lifts, a quieter problem is emerging - abnormal liver tests in young, seemingly healthy gym-goers chasing quick results. As shortcuts to a "perfect physique" become more common, so do the hidden risks to liver health. Here's what's really going on beneath the surface.

We spoke to Dr Venkatesh Reddy Raya, Consultant - Gastroenterologist, Hepatologist and Therapeutic Endoscopist, Arete Hospitals, who explained whether gym supplements and unsafe infections can damage the liver.

When Fitness Hides a Hidden Risk

A situation that liver specialists are seeing more often now involves young men who spend regular time in the gym, appear physically fit, and have no major medical history - yet their liver tests suddenly come back abnormal.

"Quite a few are trying to gain muscle quickly before a competition, vacation, wedding, or simply to achieve a certain physique. Somewhere along the way, supplements, injections, or performance-enhancing products become part of the routine. What many do not realise is that the liver ends up handling everything that enters the body, including substances marketed as fitness support," noted Dr Raya.

The Myth of "Safe Because It's Sold Openly"

"One common misunderstanding is that products sold openly in gyms or online must be safe. That is not always the case. Some powders, capsules, or injectable products may contain ingredients that are not fully disclosed on the label. Occasionally, steroids or hormone-related compounds are mixed into products without users even realising it," explained Dr Raya.

Silent Damage Before Symptoms Appear

The problem is that liver damage does not always announce itself early. Someone may continue going to the gym daily, lifting weights normally, and feeling physically energetic while inflammation is quietly developing in the background.

"When symptoms finally appear, they are often ignored initially. A person may notice loss of appetite, unusual tiredness, itching, dark urine, nausea, or heaviness in the abdomen and assume it is due to diet changes or intense workouts. Yellowing of the eyes usually alarms people, but by then the liver may already be under significant stress," said Dr Raya.

Anabolic Steroids: A Recurring Concern

Anabolic steroids remain one of the bigger concerns. These are sometimes taken as tablets or injections to increase muscle size faster. In clinic, it is not unusual to meet patients who started them based purely on gym advice without understanding the medical risks involved. Some have no clear idea what they were actually taking.

The Danger of Unsafe Injection Practices

"Injection practices create another problem altogether. Injections taken in informal settings, especially where hygiene is questionable or needles are reused, increase the risk of hepatitis B and hepatitis C infection. Many younger users underestimate this risk completely," warned Dr Raya.

When Supplements Turn Into a Cocktail of Risk

Protein supplements alone are not necessarily harmful when used sensibly and obtained from reliable sources. More trouble is seen when several products are mixed together for months - fat burners, muscle boosters, steroids, pre-workout stimulants, and injectable compounds taken simultaneously without supervision.

Why Doctors Often Don't Get the Full Picture

"Doctors also notice that many patients do not mention these products during consultation unless specifically asked. Supplements are often viewed as part of gym culture rather than something medically relevant," added Dr Raya.

Social media has added to the pressure. Constant exposure to dramatic body transformation videos has created unrealistic expectations about how quickly the body should change. As a result, shortcuts become tempting.

Bottomline

Dr Raya concluded, "Exercise and fitness are unquestionably good for health. The concern begins when speed becomes more important than safety. Muscle can be rebuilt. The liver does not always recover so easily."
