Question: what is dehydration?

Your body regularly loses water through sweating and urination. If it isn't replaced, you get dehydrated. Adults at risk include athletes, people who work in the heat, older adults, and those with chronic conditions.
Dehydration takes place when your body loses more fluid than you drink. Common causes of dehydration include:
The Mayo Clinic recommends women drink 92 fluid ounces (11.5 cups) per day and men drink 124 fluid ounces (15.5 cups) daily. Individuals on the go, athletes and people exposed to high temperatures should increase their water intake to avoid dehydration.
When too much water is lost from the body, its organs, cells, and tissues fail to function as they should, which can lead to dangerous complications. If dehydration isn't corrected immediately, it could cause shock.
Dehydration can be mild or severe. You can usually treat mild dehydration at home. Severe dehydration needs to be treated in a hospital or emergency care setting.

Question: What are the potential risk factors associated with dehydration?

Athletes exposed to direct sun aren't the only ones at risk for dehydration. In fact, bodybuilders and swimmers are among the athletes who commonly develop the condition, too. Strange as it may seem, it's possible to sweat in water. Swimmers lose a lot of sweat when swimming.
Some people have a higher risk for developing dehydration than others, including:
people working outdoors who are exposed to excessive amounts of heat (for example, welders, landscapers, construction workers, and mechanics)
older adults
people with chronic conditions
athletes (especially runners, cyclists, and soccer players)
infants and young children
people who reside in high altitudes

Question: How do doctors usually figure out if someone has dehydration, diagnosis?

Before beginning any tests, your doctor will go over any symptoms you have to rule out other conditions. After taking your medical history, your doctor will check your vital signs, including your heart rate and blood pressure. Low blood pressure and rapid heart rate can indicate dehydration.
Your doctor may use a blood test to check your level of electrolytes, which can help indicate fluid loss. A blood test can also check your body's level of creatinine. This helps your doctor determine how well your kidneys are functioning, an indicator of the degree of dehydration.
A urinalysis is an exam that uses a sample of urine to check for the presence of bacteria and electrolyte loss. The color of your urine can also indicate dehydration when combined with other symptoms. Dark urine alone can't diagnosis dehydration.

Question: What are the possible complications that could arise from dehydration?

Untreated dehydration can lead to life-threatening complications, such as:
heat exhaustion
heat cramps
heatstroke
seizures due to electrolyte loss
low blood volume
kidney failure
coma

Question: What are the ways to prevent dehydration?

Here are some ways to prevent dehydration:
If you're ill, increase your fluid intake, especially if you're vomiting or having diarrhea. If you can't keep down liquids, seek medical attention.
If you're going to exercise or play sports, drink water before the activity. At regular intervals during the workout, replace your fluids. Make sure to drink water or electrolytes after exercise, too.
Dress cool in hot months, and avoid being out in direct heat if you can avoid it.
Even if you aren't active, drink the recommended amount of fluids.
