Mark R. Lenthe, DO

Dr. Mark Lenthe brought his skills in family medicine to Tanner Clinic Layton about six years ago following years of active duty as a major in the U.S. Air Force. He last provided health care to active-duty airmen and and their families stationed at Hill Air Force Base. Many of those patients have followed him west across I-15 to Tanner Clinic, and the flow continues as more HAFB patients make the switch. He continues to accept new patients to his clinic in Layton.

Dr. Lenthe is a native of South Ogden and attended Bonneville High School where he graduated summa cum laude and was an All-State running back for the Lakers football team.

Dr. Lenthe began his college education at Weber State University, graduating with cum laude honors in microbiology. He completed his medical degree at Touro University College of Osteopathic Medicine in Vallejo, Calif., where he earned a D.O.

Dr. Lenthe was named chief resident during his Family Medicine residency at the University of Nebraska Medicine Center in Omaha. He also practiced at Erhling Bergquist Hospital at nearby Offutt AFB.

While a physician at HAFB, Dr. Lenthe was chairman of the Pharmacy and Therapeutics Committee, which oversaw formulary changes. He also oversaw the Coumadin Clinic.

Dr. Lenthe is a board-certified family medicine physician focusing on disease prevention and education, diabetes, high blood pressure, high cholesterol, sports medicine, dermatology and osteopathic manipulation, as well as all areas of family well care.

Dr. Lenthe leads an active lifestyle, particularly enjoying snow- and water-skiing and boating with his wife and three children. At other times, you’ll find him on the under side of water scuba diving. He also enjoys time with his son while coaching a local competition soccer team, the Morgan Storm.

Cholesterol's Hiding Places

You may be surprised at the amount of cholesterol that foods dish up. For example:

▸ Pan-fried beef liver:   550 mg for 4 oz.

▸ Egg yolk:    184 mg

▸ Double Quarter Pounder with cheese:    165 mg

▸ McDonald’s Triple Thick Shake: 100 mg

▸ Big Mac:    75 mg

▸ Chocolate ice cream:    22 mg for 4 oz.

▸ Ham:    106 mg for 4 oz. serving

▸ Greek yogurt:    9 mg in a container

▸ Plain bagel:    0 mg

▸ Olive oil:    0 mg

▸ Egg whites:    0 mg

▸ All nuts and fruit:    0 mg

The National Cholesterol Education Program recommends that most people eat less than 200 mg of cholesterol a day. The average American man eats 360 mg of cholesterol each day. The average American woman eats between 220 mg and 260 mg.

Even with Low Cholesterol, You Shouldn't Be Parking in the Fast (Food) Lane

Genes are like family members. Some are easy to have around — like intelligence, or a high metabolism.Others, however, are trouble from the get-go. Such as cholesterol.

Despite the widespread assumption that cholesterol is the result of Big Macs and Whoppers, the condition is often caused by genes that either: 1) Cause you to produce excessive cholesterol; or 2) Limit your liver’s ability to break down cholesterol.

If high cholesterol — or hypercholesterolemia — runs in your family, it will take less of the “bad” cholesterol LDL in your diet to push you into having high cholesterol.

“Some people think high cholesterol is indicated by diet, but probably 80 percent of it is genetic,” says Dr. Mark Lenthe, a family medicine specialist at Tanner Clinic Layton.

And like most family doctors, Dr. Lenthe will point to that other large chunk of us. Fast food can easily cause high cholesterol. So diet and exercise are essential in controlling high cholesterol, whether it’s from dad or bad food. “You just can’t rely on medicine,” said Dr. Lenthe.

Is it ‘good’ or ‘bad’ cholesterol?

Cholesterol is a fatty, waxy-like substance in our blood that our bodies produce naturally — in fact, cholesterol is vital for a healthy brain. The cholesterol we consume is the leftovers of malts and hamburgers.

Good vs bad cholesterol

Cholesterol can’t dissolve in blood, so “transport proteins” take it where it needs to go. For instance:

▸ LDL (low-density lipoprotein) cholesterol is the type that lets these fatty cells stick to the inside of veins and create plaque. Plaque can build to a point where it narrows the veins or causes clots. This is the cholesterol we want to lower.

▸ HDL (high-density lipoprotein) cholesterol, on the other hand, actually helps moves the fat from blood so we can expel it. HDLs also helps prevent cholesterol from clumping into plaque.

Triglycerides a product of fast food

And then there are triglycerides, another type of fat that circulates in our blood, designed to provide the energy our bodies need, said Dr. Lenthe. High triglyceride levels typically cause problems with the liver and pancreas and put you at risk for what’s disgustingly called a fatty liver, where fat takes over and destroys your liver.

Plus, he adds, high triglycerides is the cholesterol that most reflects diet. During his tenure at Hill Air Force Base, he says, “I’d have young airmen who ate at McDonald’s and Burger King every day, and their triglycerides were over 500. I just got them off the fast food and their triglycerides went down.”

Risk factors becoming more important

New guidelines advise doctors to not rely on whether the LDL level is high or low, but rather on risk factors. “We used to concentrate on getting LDL numbers down to a certain level,” said Dr. Lenthe. But recent recommendations are to “concentrate more on the risk factors.”

The risk factors include:

▸ Family history of heart disease or high cholesterol

▸ Diet high in fat and cholesterol

▸ Overweight

▸ Inactive lifestyle

▸ Age (arteries harden as one ages)

▸ Overall health (including diseases like diabetes)

In addition to diet and exercise, high cholesterol and the resulting plaque can be lowered by statins, such as Crestor and Lipitor. “Studies have shown that statins decrease the size of plaque,” he said.

Doctor's Orders

Primary-care physicians like Dr. Mark Lenthe do a lot of counseling. However, patients typically remember only 20 to 30 percent of what the doctor advises. That’s why Dr. Lenthe offers plenty of informational handouts for patients to read when they’re less stressed.
