There are many reasons for dehydration to develop depending on the circumstances and for the most part it is accidental. People can get busy and not think to drink water throughout the day or they may be sick and drinking water can make them feel worse. In some cases, it can be hard to come by water that is safe for drinking, such as when you are traveling, hiking, or camping, and you weren’t prepared with extra water. Other causes of dehydration can be linked to medical conditions that can cause your body to lose water at a greater rate than normal. For example, diarrhea and vomiting both cause the body to lose water and electrolytes, especially when one or both come on suddenly and severely. Fevers are also responsible for the loss of water in the body, with higher fevers causing the body to lose even more water. Sweating is one of the most common means of water loss, whether due to a hot climate or environment, or through rigorous exercise. During exercise, it is important to replenish water regularly through your workout to ensure you don’t become dehydrated. Increased urination will cause the body to lose water, whether it is through diabetes that is undiagnosed or not under control, or the result of certain medications that cause you to urinate more frequently. These medications will typically have a warning on them to drink extra water.
