If your pages are indexed by google, you don't need to update your sitemap and upload it again, except you makes big modification of your content. Sitemap will only help indexing, it doesn't help rankings. If your pages are all indexed by google, sooner or later, google will update any modifications made by you on your pages.
Just overwrite your old sitemap with your new sitemap file when you update. Google should by itself notice that the sitemap has changed.
I realized that everytime i update my sitemap, my indexing goes missing a few pages. Is this a myth or fact?
