When you look down at your hands and notice prominent, raised, or bluish veins, it’s natural to wonder whether they signal something about your overall health. Some online sources suggest that visible hand veins might reveal hidden kidney problems. But how accurate is that claim?

Low body fat
Genetics
Exercise
