On average, people with mental health concerns don’t get the same level of medical care as people without mental health concerns. Why? A phenomenon called diagnostic overshadowing.
It’s a process by which health professionals incorrectly presume that physical symptoms are a consequence of their patient’s mental illness. As a result, people get inadequate diagnosis or treatment of their overall condition (Jones et al, 2008).
For example, a patient being treated for acute anxiety may have chest pain and shortness of breath, and a clinician is more likely to attribute these to their mental illness than to investigate them in their own right as potentially important signs of something else going on.
Over the long run, this kind of oversight leads to alarming statistics like this:
If we’re talking about social determinants of health, diagnostic overshadowing of mental health patients is a really big one.
My reaction to this is that the standard of care must be changed. It is understandable that treating mental health can take priority at times, because it feels very immediate to have a panic attack, or to feel suicidal. But clinicians cannot stop at treating only the symptoms of mental health. When one digs further into the patient’s whole physical and mental symptom picture, it is often the case that other conditions are discovered.
Below is a list of some of the underlying causes and contributors to depression alone (some more common than others). These conditions should be considered (within reason) and either ruled out or treated in anyone seeking help for their mood:
Nutritional deficiencies and blood sugar issues: food allergies, diabetes, hypoglycemia, anemia, vitamin deficiencies
Sleep issues: pain, sleep apnea, circadian rhythm disturbance
Hormonal imbalances: hyper- or hypothyroidism, sex hormone imbalances, PMS/PMDD, Cushing’s disease, Addison’s disease, high levels of PTH, pituitary dysfunction
Infections: Influenza, mononucleosis, syphilis (late stage), tuberculosis, viral hepatitis and pneumonia, SIBO, candida
Autoimmune conditions: celiac disease, multiple sclerosis, rheumatoid arthritis, lupus
Organ pathologies: heart problems, lung disease, liver disease
Structural issues: chronic pain, poor circulation, head injury, inflammation, dental issues, tumors
Functional: lack of sunshine, exercise, or nourishing relationships
Many pharmaceuticals and substances
Thankfully, clinicians are beginning to ring the alarm on diagnostic overshadowing and aim to raise the standard of care for people that struggle with mental health. I make it a large part of my work to investigate possible conditions that exist in parallel or in cause-and-effect cycles with the presenting mental health concern.
Mental health and physical health are not independent. The two cannot be separated from each other, nor should the presence of one overshadow the other and lead to poor overall care.
The most important thing if you are struggling with your mental health is to not give up seeking the right care for you. To get an idea of what this approach is like and if it is a path for you, consider booking a consult with me to hear more about my whole-person, patient-centred approach.
