Is it normal for fingers to swell up during treadmill

Sometimes, endurance athletes develop hyponatremia hi-poe-nuh-TREE-me-uh — an abnormally low level of sodium concentration. Swollen fingers and hands may be a sign of hyponatremia, but other signs, such as confusion and vomiting, are more prominent than is swelling.

Drinking too much water, particularly during a marathon or similar long, strenuous event, may cause your body's sodium to become so diluted that you become hyponatremic. Hyponatremia requires immediate medical attention. There's no proven way to prevent or reduce most exercise-related hand swelling, but these tips may help ease discomfort:. If you have any type of hand swelling that does not go away after exercise or causes pain, you should let your doctor know.

But, if your hand swelling occurs only when you're walking for exercise, the Mayo Clinic says to try these prevention tips:. Chris Iliades, MD.

Heres What We Know Endurance exercise like walking or running increases blood flow in order to meet the body's increased demands for oxygen. During exercise, your working muscles demand more oxygen and so blood flow is directed away from the extremities like fingers and toes to the muscles that need it—such as your quadriceps, glutes, and hamstrings.

When blood flow is directed away from your hands and fingers, they get colder. As a result, the blood vessels in your hands may start to open wider, causing them to swell, especially if you are exercising in cold weather.
