Liver Enzymes and Exercise

In recent years, there are many indications that liver enzymes levels in the blood and exercise have some kind of association.

For example, taking a blood test close to the time you exercised, could result elevated levels of liver enzymes in the results.

The act of exercising has an affect on the level of liver enzymes, and when taking a blood test timed closely with the exercise, it could result with misleading outcome.

The physician will probably think the blood test results is because of viral infection, which is not true.

However, there is an easy workaround to this situation.

Before taking any blood test, make sure you haven’t exercised beforehand.

It will prevent any unnecessary conclusions regarding your conditions.

It is recommended to wait for about 3 hours after the initial exercise before going through a blood test; this will prevent any mistakes in the blood test related to liver enzymes and exercise.

    Hello,

    In the past year I have had several blood tests, as I am diagnosed with fatty liver. The first three (February, June/July, October of 2014) showed normal ALT and AST, but heightened bilirubin count at 24, 29, and 22 respectively. I was told that my bilirubin count was a bit high but not to worry. I recently had to see a new doctor when I went for my follow up. He ordered a bilirubin test but no AST or ALT. Bilirubin came back at 30. He seemed more concerned.

    Dr. Bar-Gomel,

    I recently (Last Friday) had a liver test completed (ALT) and it came back slightly high (73) on their testing range provided, (5-50). I did workout very hard the day before the test. I have been working out since I was 14, and I am 44 years old. I am 5-10, weigh 191 lbs., and have about a 12% body fat composition, BMI of 26%, average BP of 122/73, and 62 BPM. I take no medication, however when I was younger I did have to take penicillin a lot for chronic strep throat and sinus infections from ages 14 to early 30’s (off and on). Daily, I take a GNC multivitamin, saw palmetto (for BPH), and vitamin D. I eat very healthy (probably too much protein), salads, lots of chicken, some lean beef, oats or sprouted breads. I very rarely drink alcohol (maybe 1 drink a month), and do both cardio (run..HR at 153 BPM) and lift weights 5 days a week (intense training), taking two days a week off. I do at time take adviI once a month maybe for back pain (pinched lower nerve). Prior to the ALT test, I was on energy drinks for 4 months that had stimulants (June through September). I do not feel bad, but sometimes fatigued perhaps, and that could be because of stress in my job (adrenalin all the time) and stress on top of working out. I have been an athlete my whole life and am a little freaked out by this. I have read and heard that its possible my elevated levels could be because of strenuous exercise, and/or consuming too much pre-workout training supplements like protein drinks/powders, energy drinks/powders? As of this post, I am not taking any supplements other than my saw palmetto and Vitamin D, until I hear back from my Doc. I even stopped consuming protein drinks/supplements and taking my multivitamin because I also read these both can be causing the issue as well. Your thoughts and or opinion would be appreciated.

    Hi,

    I had elevated liver enzymes years ago but only slightly. By like 2 or 3 points. I had an ultrasound and they said I had mild fatty liver and now I’ve lost 85lbs, to reverse that fatty liver. A few months after my first initial testing, after I had lost 20 lbs they went down in the normal range. I just got tested a few weeks ago and my AST level is now 48 while my ALT level is 40. I’m so confused as to why this is happening. I have been eating right and getting an hour of exercise each day.

    Please help. I’m worried. I’m only 21. I would like to live my life without worry of this.

      Hello Mae,

      Could you please tell me what’s your current weight and height?
      In addition, please write me down what do you usually eat during the day.

      You probably have nothing to worry about as your liver enzymes are elevated just slightly.
      Have you re-done an ultrasound?

      Waiting for your reply,
      Dr. Mark Bar-Gomel
