Both issues have very high symptoms for flaky skin,
hair loss,
and fatigue. You also might want to check to see how your sleep habits are. Sleep Apnea is a very dangerous issue if unchecked. It also can produce skin issues, fatigue, the burning eyes, stomach issues, shortness of breath. In my opinion, Diabetes, Thyroid issues, and sleep disorders can all three mask the other for symptoms together. I would get all three of these areas well checked. Just to rule out any of this.
