8. Personality changes
It is not common for people to notice a personality change. If you don’t get enough sleep and feel tired all the time, this can cause changes in your personality. You might feel angry or depressed all the time.
You may find it difficult to do simple tasks and that things you used to enjoy doing are now overwhelming. Others will notice the changes, while others won’t. These personality changes can affect your work as well as your social life. This symptom can be caused by a variety of different conditions.
You doctor may order blood tests to determine if there is a mineral or vitamin deficiency, such as magnesium or iron. Once the root cause is identified, a diagnosis and treatment plan will help you get back to normal.
