3. Dehydration
Dehydration is caused by expelling more fluids than you are taking in. As mentioned, if you are suffering from appendicitis you may not feel very hungry, which means that you are not eating as much food. In addition, if you have diarrhea or are nausea and vomiting, you may not want to take in any fluids or solid food.
When you are not taking enough of these things in, you may end up being dehydrated. When you become dehydrated, your blood pressure may drop and you may feel even worse. If you start to feel quite weak, make sure that you try to drink as much water as you can.
You will also want to make sure that you go to your doctor so that the cause of your dehydration can be determined. Your doctor will also be able to tell you if your appendix is the cause for you feeling dehydrated.
