Sickle cell disease is an inherited blood disorder
that turns normal, round blood cells into misshaped cells that look like
sickles or crescent moons. These sickled cells can get stuck in blood vessels,
blocking blood flow and causing severe pain as well as damage to organs,
muscles, and bones.
Dehydration can trigger blood flow to slow down, which
may cause a painful event in a person with sickle cell disease.
Dehydration occurs when the body loses too much water. People can
lose large amounts of water when they:
- Have diarrhea.
- Have a fever over
100°F (37.8°C).
- Vomit.
- Sweat from physical activity or
exposure to heat.
- Urinate in large amounts.
A person with sickle cell disease should seek medical care for
dehydration right away.
If you have sickle cell disease, don't let a fear of dehydration stop
you from exercising. Just be sure to drink fluids before, during and after your
activities. If your child has sickle cell disease, let teachers and other
school personnel know that children who have sickle cell disease need water or
other fluids available at all times. You can also provide written instructions
listing the symptoms of dehydration and what to do if it occurs.
