BMI Explained

Body mass index, or BMI for short, is a simple calculation that gives clues about potential health risks a patient faces. A high BMI indicates a person is carrying sufficient weight to contribute to problems like type 2 diabetes and heart disease.

Are Skin Tags Harmful?

Though skin tags are technically tumors, they’re benign, meaning they aren’t cancer, and they won’t harm you. However, it’s possible to mistake other skin conditions for skin tags, so don’t take any growth for granted.

Self-Care Tips for Diabetes

No matter what type of diabetes you have, you’re a crucial part of the care process. Managing the disease takes a combination of your efforts as well as those of your medical support team. The biggest self-care payoff comes from these areas.
