If I feel like my hair is falling out more than before, should I go to the hospital right away?

Lately, there has been a significant increase in the amount of hair falling on the floor whenever I dry my hair after a shower.

At first, I thought it might be because of the season, but
It seems like my parting line has gotten a little wider than before, so I've started to get self-conscious.

It doesn't seem like people around me are not noticing yet, so I'm wondering if I should even go to the hospital.
I wonder if I'm worrying too early for no reason.

I'm even more worried because I've heard that it's important to manage hair loss in the early stages.

I would like to hear from those who have experienced similar changes and undergone testing what prompted them to visit the hospital.
