Why are my PDFs becoming heavyweights?

Why do minor changes to a PDF in Photoshop CS3 radically increase the file size (from 200k to 6.5MB)?

I'm no graphic artist (as evidenced by this question), but I'm an intermediate user of Photoshop and frequently asked to make changes to existing documents. Right now, I'm trying to change the address on an old PDF to our new address. The old PDF is roughly 200kb before editing, but 6.5MB after editing. What am I doing wrong?
Here's my step-by-step:
1) Open PDF in Photoshop CS3
2) Create new layer
3) Use text tool to type out the new address (basic Arial font) over top of the old address
4) In background layer (the original PDF), use the paintbrush tool to cover up the old address
5) Save as PSD
6) Flatten layers
7) Save as PDF, without Photoshop editing capabilities
The doc is a full sheet, 8.5x11; It's a photo-heavy step-by-step guide, but the pictures aren't high-res or great quality. Photoshop CS3, Adobe Acrobat, Win XP SP3. If you need any other info or want the files themselves, I'll be glad to provide.
