Understanding the Ten Common Causes of Blood Clots

4. Dehydration

You are at an increased risk for blood clots when your body becomes dehydrated. Most often, dehydration happens when you exert a lot of energy, don't drink enough fluids or are exposed to heat. When you become dehydrated, your blood vessels narrow, and your blood itself becomes thicker. This can have an adverse effect, and the potential for a blood clot to form increases. The risk is even greater when paired with other factors, such as inactivity or smoking. To avoid this scenario, make sure to drink fluids, especially if you know you'll be in warm environments or will be exerting yourself.
