Can what you eat support with Endo Belly? A dietitian explains

Endometriosis is a complex and often misunderstood condition that affects millions of women worldwide. Beyond its widely recognised symptoms of pain and infertility, there exists a lesser-known aspect of this condition that significantly impacts daily life: endo belly.

What is endo belly?


It's not just regular bloating; it's an extreme swelling of the abdomen that occurs in conjunction with the menstrual cycle. This bloating is attributed to heightened sensitivity of the intestinal wall in patients with endometriosis. This reduced pain threshold resembles that of individuals with irritable bowel syndrome (IBS), contributing to shared symptoms and potential misdiagnosis between the two conditions.


The similarity in symptoms between endometriosis and IBS can often lead to confusion and delayed diagnosis. Studies have shown that women with endometriosis are more likely to receive an initial misdiagnosis of IBS due to overlapping symptoms. However, it's crucial to understand the distinctions between the two conditions to ensure accurate diagnosis and appropriate treatment.


Here are the key differences between endo belly and bloating associated with IBS:


  1. Cause and Timing: Endo belly is directly linked to endometriosis and its presence in the pelvic area. It intensifies during the latter half of the menstrual cycle, aligning with hormonal fluctuations. In contrast, bloating in IBS isn't tied to the menstrual cycle but can be triggered by various factors like stress, certain foods, or gut motility issues.

  2. Nature of Symptoms: Endo belly primarily involves abdominal discomfort and swelling related to the menstrual cycle and the presence of endometrial tissue. On the other hand, IBS-related bloating accompanies digestive symptoms such as abdominal pain, changes in bowel habits, and general bloating.

  3. Diagnosis: Identifying endo belly involves diagnosing endometriosis itself through medical evaluation, which may include imaging or laparoscopy. IBS diagnosis follows specific criteria, known as the Rome criteria, focusing on recurring abdominal pain/discomfort associated with changes in bowel habits.


Understanding these distinctions is crucial because the management and treatment approaches for endometriosis and IBS differ. While there might be overlapping symptoms, a precise diagnosis is essential for tailoring effective treatment strategies. Accurate diagnosis not only removes confusion but also ensures appropriate management that addresses the root cause of the symptoms.



The link between sex hormones and gut symptoms


The gut is complex, influenced by a various factors, and one often overlooked aspect is the profound impact of sex hormones.


Gender-specific differences in bowel function have been noted by various researchers, with women typically being more susceptible to IBS, experiencing a higher frequency of symptoms such as constipation, flatulence, abdominal pain, and incomplete emptying compared to men. These disparities extend to cyclical variations in symptoms, notably during the menstrual cycle.


During the late luteal phase and menstruation, when sex hormone levels plummet, there's often a surge in complaints among women with IBS, particularly concerning flatulence. Interestingly, when hormone levels soar during pregnancy, symptoms tend to significantly improve. Menopause, characterized by reduced sex hormone levels, correlates with a lowered incidence of IBS in women, although a potential rise in constipation.


The influence of hormones extends beyond symptom variations. Sex hormones impact the brain-gut connection and the physiological processes within the intestines. They affect sensitivity, motility, intestinal barrier strength and the functionality of the gut.


Ultimately, acknowledging and delving into the intricate relationship between hormones and gut health offers a path toward more comprehensive and effective approaches to managing gut symptoms for women living with endometriosis and/or IBS.


How does nutrition play a part with endometriosis?


Although not the only factor nutrition may play a significant role in managing endometriosis.


The relationship between inflammation, oxidative stress, and endometriosis has prompted interest in anti-inflammatory diets. Omega-3 fatty acids from fish oil have shown promise in reducing recurrence risk and alleviating pain. Antioxidant vitamins like C, E, A, selenium, and zinc seem to combat oxidative stress, with citrus fruits and specific supplements showing potential in decreasing endometriosis risk and alleviating symptoms


Vitamin D, known for its various effects including anti-inflammatory properties, has also been associated with endometriosis. Lower serum levels are linked to pelvic pain, while higher plasma levels show a potential protective role against developing the condition.


While more comprehensive research is needed, these dietary insights offer potential foundations for managing symptoms and potentially lowering the risk of developing endometriosis.


How does nutrition play a part with endo belly?


An anti-inflammatory diet may help - but it would not be a first-line strategy due to the lack of evidence in this area. Instead I would want to explore the root causes of your gut symptoms.


A common issue I see in clinic is constipation. This can cause a host of symptoms such as flatulence, bloat and discomfort. This can often be managed with diet and lifestyle advice.


Other common triggers may be food intolerances, a diet high in fermentable carbohydrates, how frequently (or infrequently) we eat - just to name a few.


The best way to get to the root cause of your symptoms is speaking with a medical doctor, and working this through with a dietitian. Dietitian's are trained nutrition professionals in this area, whilst many other nutrition professionals are unlikely to have the clinical training and expertise to provide adequate, evidence based support.


Gentle reminder


If you suspect that your symptoms might be related to endometriosis or IBS, don't hesitate to discuss them openly with your medical doctor.. Awareness, understanding, and early intervention are pivotal in managing these conditions and improving overall quality of life!


There is certainly plenty a dietitian can do to support you with your symptoms. If you would like personalised advice, my clinic doors are always open.
