My goal is to make it 100% easy for you to follow your specified dietary plan and lifestyle changes to meet your goal. I always review your food likes/dislikes, make necessary changes paying attention to your food likes. I believe that good nutrition is the one that is eaten, good diet plan/lifestyle change is the one that is simple and easy to follow for a long time. I use visuals and measures to bring points home and clear, you don't have to take notes, I do give handouts which you might never have to read because my points are always clear.

I am also a Certified LEAP Therapist and help clients improve their struggles with IBS using the MRT and Low FODMAPs plan.
Do you find that food is ruling your life? Has food has become a burden from years of dieting, disordered eating or unresolved digestive issues? Is what, when and how to eat taking up too much of your time and energy? You deserve to enjoy food and feel well. It is possible to lay down that burden by ending the diet and binge eating cycle. It is also possible to eat without fear and stop letting your digestive symptoms dictate your life.

You might feel like you’ve tried every diet, every plan, every reset, but still feel stuck. Maybe you’re constantly thinking about food, swinging between feeling in control and overwhelmed. You’re tired of the guilt, the spirals, and the all-or-nothing mindset. Physically, you might be dealing with bloating, fatigue, or hormone concerns, and wondering if it’s possible to care for your health without being on the constant merry go round of trying things and then giving up. If this sounds familiar, you’re not alone. Healing is possible, and it doesn’t have to be exhausting.

Due to personal struggles with migraines and IBS, I understand what it is like to not have answers.
Are you struggling with tummy troubles? Chronic constipation, diarrhea, abdominal pain? You've seen a gastroenterologist and been told that everything is "normal." Have you been told you have fibromyalgia but not experienced any relief? Is your child an extreme picky eater, and you feel you may pull your hair out trying to get them to eat? Have you or a loved one been placed on a feeding tube with no direction on how to manage outside of the hospital? No help with optimizing nutrition status and getting the best nourishment?

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.
