Hi I’m Antonella

My name is Antonella Dewell. I am a registered dietitian based in the San Francisco Bay Area and I provide consultations both locally, in person, or virtually to people outside the area. I am passionate about helping people improve their health and quality of life through dietary changes. I see a range of GI issues, including, but not limited to IBS, SIBO, and IBD. I have been trained on the low FODMAP diet for IBS by Monash University.

How I can help

Living with a digestive issue can be difficult and greatly impact your personal, social, and professional life.

But if doesn't have to be that way: there are science-backed dietary changes you can make to improve your condition. I have focused my career to specialize in digestive health and I know what works.


My amazing patients

I had attempted to follow the low FODMAP diet on my own in the past but it was only with Antonella’s guidance that I was able to implement it correctly and find out which foods triggered my symptoms. Now I have control over my diet and my symptoms, instead of being controlled by them. I couldn’t have done it without her.
— Rachelle, Santa Cruz

Working with Antonella, my attitude towards this diet changed: the low FODMAP foods and grocery shopping lists were very useful and made me feel like I did have a variety of foods to choose from and that this program wouldn’t be too hard to follow after all.

Working with Antonella to implement the low FODMAP diet protocol, I was able to free myself from the severe abdominal pain that was not allowing me to get a good night of sleep for the past 10 years
