*****Split movie 2017 possible spoiler***

Something that I often wondered about is weather or not there were physical differences in my alters. There is a scene in the trailer for split that is causing controversy because it states that, "people with Dissociative Identity Disorder can change their body chemistry." While I am not a doctor or a psychologist, or a scientist I believe this. 
    Just because I believe it doesn't mean it's as drastic as the media makes it out to be. In my own personal experience my facial features, eye color, mannerisms, voice, and handwriting generally change between different alters and myself. There are cases (like in the video above) where differences can be as drastic as eyesight, allergies, and illnesses. I do not experience these kinds of changes to date. 

Another thing that people seem to wonder about is non-human alters and how they change when they come out. There is a wolf in our system. Her name is Charlotte and when I feel like she is going to come out there are some physical changes that help me know its her. My bones start to ache, my hands feel bulky, and I feel like I can see, hear, and smell, a little better. I have not tested this so it may not be by a lot but I notice it. My girlfriend has told me that being out can sometimes hurt Charlotte because she feels like her "bones are not where they are supposed to be" or she can get confused because her joints are different than a humans. 
    Now I am not saying that she is physically changing from wolf to human or vice versa, I'm just saying it can get uncomfortable for her and me too sometimes and I count that as a physical change. So, in the case of non-human alters I do believe there is some level of a change but I do not turn into a werewolf at the full moon. 

Comments or  questions about physical changes in alters, or about DID in the media are welcome. I will try to answer to the best of my ability based on my experience, the experiences of others, and research I've done. Any links or references will be posted at the end of each post.
