Protein Shakes and Constipation

I apologize if this topic has been covered but I'm fairly new to the site. I like to use protein shakes as my snacks because they make me feel more energized and drinking is sometimes easier for me than eating snacks. But when I went through a 5 day period of constipation and the bloating and the lack of weight loss that resulted, someone suggested that the protein shakes were the culprit. Does anyone else have any experience or knowledge about this and advice on how I can still use the shakes but offset the constipation effect?
