It's easy to be depressed if you're at risk for diabetes-- it usually means you're in pretty poor shape, and not getting any better.

Do yourself a huge favor: Take action, not meds--because a new study finds patients at risk for diabetes who take antidepressant drugs are more likely to come down with the condition.

Researchers at the Johns Hopkins School of Medicine tracked 2,665 at-risk volunteers for a median of 10 years. Some were taking metformin, others a placebo, and still others went with lifestyle changes--and some in each group were also taking an antidepressant.

They found that patients who were taking any type of antidepressant along with their placebo or lifestyle changes were nearly 2.5 times more likely to turn their diabetes risk into actual diabetes.

The common-sense response to this would be to urge patients not to take antidepressant drugs.

After all, they don't work... and there's one thing that's been shown to help beat both depression AND diabetes: exercise.

Studies have found that exercise is at least as good as some powerful antidepressant drugs--and since it can help you get back into shape and lower your risk for diabetes, it's a no-brainer, right?

Nope. Apparently, that would make too much sense--because you won't find that advice in the study published in Diabetes Care.

Instead, researchers say depressed patients at risk for diabetes who take the diabetes med metformin along with their antidepressant drug have a lower risk of getting the disease.

But that's a side effect party waiting to happen.

Antidepressant drugs can come with personality changes, sexual side effects, weight gain, insomnia, fatigue, headache, nausea, anxiety, and even suicide.

Metformin is no picnic either: nausea, vomiting, diarrhea, gas, heartburn, headaches, and even a potentially deadly condition called lactic acidosis.

It even smells bad--metformin's odor has been described as everything from "wet dog" to "dead fish." (Read about it here.)

Bottom line: Both diabetes and depression can be wiped clean without meds through lifestyle changes and nutritional therapy. If you can't find a doc willing to find a real solution, follow your nose to a new doctor instead.
