Is Your Forehead Related to Your Irritable Bowel Syndrome?

”The craniofacial morphology of patients with celiac disease reveals an altered pattern of craniofacial growth,“ claims an article titled ”Large Forehead: A Novel Sign of Undiagnosed Celiac Disease,“ in a 2005 issue of Digestive and Liver Disease.

Specifically, the study found that people who suffer from gluten intolerance had a larger forehead due to abnormal growth patterns as a child. To determine if this is a factor for you, measure from the bottom of your chin to the bottom of your nose, from the bottom of your nose to between your eyebrows, and from between your eyebrows to the top of your forehead.

The face should be divided into equal thirds; if your forehead is larger than the other two sections, there's a good chance that gluten is affecting your gastrointestinal condition. Furthermore, a 2009 Polish scientific article states that one of five IBS patients suffer from positive antibodies to gluten!

Whether you have a large forehead or not, if you suffer from digestive irritability, there are many possible causes and treatment options that can greatly improve your life.

Leonardo da Vinci Meets Celiac Disease

Chiara Zanchi et al.

ABSTRACT
Background and Aim: Leonardo da Vinci’s face symmetry derives from
3 equal craniofacial segments: trichion-nasion (tn), which represents the
superior third of the face, nasion-subnasal (ns) that is the medium third of
the face, and subnasal-gnathion (sg) that is the length of the lower third of the
face. It has been reported that adult subjects with celiac disease (CD) can be
identified on the basis of a greater extension of the forehead in comparison to
the medium third of the face, with a high tn/ns ratio. The aim of the present
study was to investigate the correlation between facial asymmetry and CD in
childhood and adulthood.

Methods: We studied 126 biopsy-proven patients with CD (76 children and
50 adults) and 102 healthy controls (43 children and 59 adults). Their faces
were photographed; the pictures were edited using a software program to
calculate the facial segments.

Results: The tn length was significantly different between adult celiac and
adult controls (7.431.46 cm vs 6.381.73 cm, P¼0.001). The cutoff of
6.5 cm tn, derived from receiver operating characteristic curve analysis,
identified 43 of 50 patients (sensitivity 86%), but 34 of 59 controls were
positive (specificity 54.2%). The positive predictive value was 56%;
however, the tn/ns ratio was not significantly different between celiacs
and controls. Neither the tn length nor the tn/ns ratio in celiacs correlated to
the time of gluten exposure.

Conclusions: Adults, but not children, with celiac disease show a forehead
extension significantly greater than controls, but this test’s specificity
appears too low to be used in the screening of CD.

[...]In his famous ‘‘Vitruvian Man,’’ a mathematic design in
which the union between scientific spirit and artistic intuition is
expressed, Leonardo da Vinci defines the ideal and perfect proportions
of the human body, and divides the face into 3 equal parts
(Fig. 1).

A recent study suggests that adult celiac patients have a
typical asymmetry of the face, with a forehead that is larger than the
other two-thirds of the face.
