It’s hard to imagine: Rapper Eminem is turning 50 this year. So are actresses Tracee Ellis Ross and Jennifer Garner.

As much of a turning point as that is for those stars, for people who have obesity before age 50, growing older is a much tougher challenge.

A study in the journal Lancet Diabetes & Endocrinology reveals that if you're severely overweight before age 50, you have five times the risk of developing an additional, life-threatening condition in the next 12 years, compared to a healthy weight person.

In addition, the researchers wanted to see how early obesity was related to developing what they call multimorbidity — having four or more serious health conditions in addition to obesity.

They found that by the time the younger obese participants were 75 years old, 53.3% of them had multiple health hazards; that’s more than six times greater risk than folks who were a healthy weight. Only 8.3% of folks who were a healthy weight had multiple health hazards.

Treatment for obesity may require lifestyle changes, support/therapy, and medical intervention using medications and/or surgery. If you're 50 or younger and have obesity, you can reduce your risk for life-shortening complications by talking to your doctor about:

• Changing your diet, along with exercise and sleep management techniques. Get a referral to a nutritionist and have a checkup to evaluate your health and determine appropriate physical activity.

• Using medication that may help with weight loss.

Together, set a realistic goal for the first six months of your new routine. At six months, if you're not seeing results, discuss surgical alternatives.
