In my last health tip I described how blood is circulated around the body. I mentioned that poor circulation can cause leg swelling, and promised to provide a fuller review of this very common problem. I'd venture to say that almost 100% of adults have noticed puffiness or swelling in their legs at some point…...

The thyroid gland is responsible for controlling our metabolism, and as such, it is often blamed for causing all manner of weight loss difficulties.

This bacterium normally lives in soil, water, deli meat, and human feces and we are exposed to it on a fairly regular basis. It may not cause symptoms until our normal intestinal bacterial colonies are…...

Did you know that our bodies have mini "air bags," located around our joints (the largest ones are in the shoulder, elbow, and hip) for protection? They are not actually filled with air - they are filled with fluid and are called bursae (plural). But they are designed to keep the joints buffered from impact.…...

I got heatstroke once when I was hiking in Arizona. As I was coming down the mountain in the final mile, I was overwhelmed with a feeling of nausea and I started dry heaving. At the time I was confused about what was happening, because I thought I had been drinking enough water during the…...
