Narrative:

After shutdown checklist completed; the #1 flight attendant (flight attendant) advised me that both the #3 and #4 fas were not feeling well due to odor or fumes they experienced during approach. The #1 explained he felt fine and smelled nothing. The first officer and I smelled nothing and also felt fine. To my knowledge; no passengers complained of feeling ill. After all passengers deplaned; I spoke with flight attendant X and flight attendant Y. They both said they had headaches; had some throat discomfort and felt lethargic. They described they saw nothing visible during landing but smelled an odor and or fume of a category D type. It was obvious to me they did not feel normal and appeared pale. I suggested they get off the aircraft and had a cart brought out for them to sit in outside the aircraft and requested paramedics. The station operations people called the paramedics; the first officer (first officer) notified dispatch and also requested maintenance. I made an aml (aircraft maintenance log) entry and spoke to the mechanic. By this time the medics arrived and checked out both fas. The medics strongly suggested both fas go to the hospital. They both agreed and were transported by ambulance to the er. They were both in the er for approximately 5 hours. I wish I had an explaination; but I have none. The aircraft was checked out by maintenance and no cause could be determined.
