My husband is 41 and just had an overall checkup that found the following: high cholestorol, elevated liver enzymes, & left axis deviation. He is 5'11 & 182 lbs. He was told to change his diet and exercise because he is 10lbs overweight, then come back in 6 weeks for another ekg & bloodwork. He eats heart healthy at home but does consume 3-4 beers in the evening & sodas at school. Heart disease runs in his family on both father & mother's side. Are dietary changes enough or should he be more concerned?
