One of the many things that is brought up by those who raise objections about the issue of Transgender is mental illness. Which to some part is a concern but not in the way most would think that it is. I will be talking about addressing these issues. First we will talk about is Gender Incongruity followed by Gender Dysphoria and the differences that reside in the two issues.
We will also look at the evidence that is part of these two issues. We should also understand that much of this topic is about the quality of life. Even in issues of mental health quality of life is important. It does not matter if you are or are not part of the Transgender community.

Gender Incongruence

The first thing to understand that all of those in the Transgender communities experience Gender Incongruence. What this means is that notable disconnection between what a person sees as their gender and what is their physical sexual characteristics (Parts). We must understand that while this disconnection exists it does not cause distress to the individual that one could diagnose with the condition of Gender Dysphoria.

Gender Dysphoria

In 2018 the WHO (World Health Organization) removed Gender Dysphoria as a mental health disorder. But instead it has been placed as a physical health issue. Which is linked with Anxiety, Depression, Self-harm, Eating disorders, Substance abuse and other problems. While every person who has Gender Dysphoria has one or more of the above secondary mental health conditions.

The Problem

The problem with the above is that while the WHO might say one thing. The rest of the world does not have to agree and follow what is suggested. Case in point with the release of what the WHO said in 2018. The Mayo clinic still regards it as a mental health issue [Link].
We also see a number of countries who have not separated the difference between the two conditions. Even though the general Transgender community recognizes the difference between them. This issue is starting to show as part of the blame lies at the feet of the Transgender community. Who within the last few years has been supporting the removal of the Gate Keeper model and trying to enforce a self diagnosis procedure. Which results in the reduction of the quality of care standards for this community. As the medical profession relies upon input from the Transgender Community to improve overall healthcare. Most of this input is a direct result of the Gate Keeper Model.

Quality of life

Now with understanding the differences between the two conditions we can look at treatment based issues. With Gender Incongruity the overall treatment is an improvement in the physical healthcare of the community as well as overall education of society and how it impacts the community. For those with Gender Dysphoria we can see that treatment of secondary conditions results in treatment for the Dysphoria. Meaning that if you work on the issue of self-harm and why the patient is acting out this then you can reduce if not eliminate the Dysphoria (simplistic view). We can also see that treatment might require direct medical transition resulting in Gender Affirming Surgery. Which has also shown a reduction in overall dysphoria as well as a reduction in suicide based issues. While Gender Incongruity might still exist in some form after Gender Affirming Surgery. But not to the level of severity that existed before.

Recently Cornell University published a paper on a overview of 72 scholarly articles and research on the above topic [Link]. Incase of this article being removed I have created a secondary page with all the links to the information that was gathered. Please understand that these are scholarly articles and most of them reside behind a paywall of some type. Though I am going to link them here [Link].
