### Patient: Doctor, I have been feeling very weak and fatigued lately, and I've noticed that I've been drinking a lot of water, but I'm still feeling dehydrated. What could be the problem?
### Doctor: It's possible that you may be suffering from hyponatremia, which is a condition that occurs when the sodium levels in your blood become too low. To treat this, we'll need to prescribe a medication that can help raise your sodium levels. In your case, we'll be prescribing sodium bicarbonate.
