When looking at individuals with bulimia, there is more dopamine drive in this reward chemical.
As such, you can’t only focus on eating.
You have to also watch for drug and alcohol or sexual addiction, shoplifting, or gambling.
These individuals just want to feel better as soon as possible.
As such, I treat a lot of these patients with an oversensitive dopamine reward system from an addiction model, asking questions such as:
- Are you sober?
- Are you finding other ways to take care of your anxiety that’s not going to make things worse in the long-run?
- Are you eating a regular meal plan?
- Are you taking care of yourself or your anxiety without making your self-esteem feel worse?
These aspects become really important to understand that their brains are very sensitive to rewards and to try to catch that and use it in positive ways.
Again, then we look at the environmental factors of eating disorders. Some of these are similar to anorexia, such as hormones, puberty, and stress. Finally, looking at the state of the disorder.
In one study that I was involved in, we looked at the middle of the brain, the dorsal mid-insula. We know that, when you ask an individual with depression about their heart rate, stomach, or bladder, it doesn’t work, putting them at higher risk.
In individuals with anorexia, there is higher sensitivity to their stomach than anything else. When we ask these individuals to think about something other than food, such as home, family, friends and then academics and stressors, the same part of the brain lights up.
It seems these individuals anxiety is being misinterpreted through their stomach about fullness and avoidance and causes an underlying problem that makes it harder for them to eat.
This can help us to understand how emotions and physical experiences of the body are related due to brain activity such as getting butterflies when excited or throwing up when nervous.
For all of this information, it appears the insula is the end-all-be-all area to provide us with information on anorexia.
If we can continue this work to understand how the circuits work and don’t work, we can start to roadmap how these connections result in symptoms around eating anxiety, body image, etc.
