It is not often we are encouraged to honor our bodies needs. We live in world that teaches us to "watch it" and "have it together", especially around weight and food. Unfortunately, this constant pressure to "be good" can play a role in constant dieting, restricting, binging, purging and an all or nothing attitude around exercise. Fortunately, we can make peace with food and our bodies again. Our approach of trauma informed nutrition counseling and coaching teaches non-diet eating and body wisdom skills to learn to trust and feel safe inside the body and manage chronic issues such as burned and stressed out, PCOS and gut health.

I work with individuals who are struggling with unwanted weight gain and undesired symptoms such as fatigue, low energy, or lack of motivation. If you are feeling overwhelmed and confused over what to eat and want to feel your absolute best again, I can help you. Maybe you’ve tried different fad diets but couldn’t stick with them. Maybe there are more underlying causes to your weight gain that you suspect, but no one will listen or help you figure it out. Maybe you prioritize everyone or everything in your life but need support and a plan that is just for YOU. Maybe all of this thinking about food has you really STRESSED OUT.

Still dealing with bloating, fatigue, hormone shifts, metabolic concerns, or symptoms that don’t make sense — even though you’re doing “all the right things”? I work with people who feel stuck between wanting answers and wanting something that actually fits real life. That perspective comes from experience: years spent navigating autoimmune symptoms and conflicting advice taught me that learning how to understand your body — not just manage diagnoses — is what actually helps you feel better. Today, I support people seeking clarity, relief, and sustainable support.

Irritable Bowel Syndrome (IBS) Nutritionists and Dietitians
What is Irritable Bowel Syndrome (IBS)?
Irritable bowel syndrome (IBS) is a general term that refers to a collection of symptoms associated with poor gut mobility and function, including abdominal pain, bloating, gas, and diarrhea. IBS is very common, with some estimates suggesting that as many as 10-15% of adults within the United States have IBS. Although the two conditions sound similar and share many symptoms, such as abdominal pain and diarrhea, IBS differs from irritable bowel diseases (IBDs), such as ulcerative colitis and Crohn's disease. In contrast to IBS which is caused by issues in the functioning of the colon, IBDs are inflammatory conditions caused by overactive immune cells within the intestine. IBDs are much less common than IBS and typically more medically severe, occasionally requiring intensive medical treatment and/or surgery. IBS, in contrast, can usually be managed effectively with lifestyle changes and less intense medical intervention.

What are the subcategories of IBS?
Medical professionals generally identify four main types of IBS: IBS-C (constipation-predominant subtype), IBS-D (diarrhea-predominant subtype), IBS-M (mixed bowel subtype), and IBS-U (undefined subtype). Identifying the predominant type of IBS an individual has can be important for determining the type of treatment that is best for them, such as the lifestyle and dietary changes that may be most appropriate, as well as any medications that may be necessary. However, individuals may also experience multiple subtypes over time, as well as experience cycles of flare-ups and symptom relief.

What causes IBS?
The causes of IBS are not well understood, but symptoms are generally attributed to issues with gut muscle contraction and changes in the gut microbiome, both of which can lead to the characteristic symptoms of IBS. These issues can be caused by a variety of lifestyle factors, such as diet and stress. While lifestyle modifications may not completely cure IBS symptoms, identifying symptom-triggering foods, consuming a balanced diet, and reducing stress have all been shown to greatly reduce symptoms. IBS can also be caused by bacterial or parasitic infections within the intestine, in which case the syndrome is referred to as "post-infectious IBS." In contrast to non-infectious IBS, post-infectious IBS is less chronic in nature and symptoms will often resolve once the infection has subsided.

What foods should I avoid if I have IBS?
Specific foods that may trigger symptoms of IBS can vary person-to-person. However, common foods that may exacerbate symptoms include high-fat foods (such as fatty meats), wheat, dairy products, highly acidic foods (such as citrus), beans, cabbage, milk, and carbonated drinks. Over time, individuals with IBS are often able to identify which foods cause their symptoms to worsen and learn to avoid such foods to manage their symptoms.
