This book, which covers Visions and hallucinations, explains what causes them and summarises how many hallucinations have been caused by each event or activity. It also provides specific help with questions people have asked us, such as ‘Is my medication giving me hallucinations?’.

Vitamin D deficiency, Psoriasis and Obesity



Type of Spiritual Experience


As this was done via previouis surveys, the extent to which the results could be analysed was limited, but it shows a correlation between obesity and vitamin D deficiency.

As psoriasis has multiple causes, and the number of eventual cases included in the study relatively small, little can be deduced about the correlation between psoriasis and vitamin D deficiency.  In the study no correlation was found, but many other studies have found a correlation.

A description of the experience

Endocrine. 2013 Oct;44(2):537-9. doi: 10.1007/s12020-013-9989-8. Epub 2013 Jun 8.  Serum 25-hydroxyvitamin D status in individuals with psoriasis in the general population.  Wilson PB.  School of Kinesiology, University of Minnesota, 220 Cooke Hall, 1900 University Avenue SE, Minneapolis, MN, 55455, USA, wilso733@umn.edu.

There is a dearth of data assessing serum 25-hydroxyvitamin D (25[OH]D) status in psoriasis.

This population-based study in the United States evaluated 25(OH)D status in psoriasis and examined the associations between 25(OH)D and psoriasis severity.

The 2003-2006 National Health and Nutrition Examination Survey was analyzed. Participants aged 20-59 years self-reported psoriasis, psoriasis body surface area (BSA), and psoriasis life impairment (PLI). Serum 25(OH)D was assessed with the DiaSorin radioimmunoassay. General linear models were used to examine the associations between psoriasis and 25(OH)D while accounting for age, gender, race/ethnicity, season, and body mass index (BMI).

Among the 5,841 participants with complete data, 148 reported a psoriasis diagnosis. Mean 25(OH)D levels and deficiency prevalences (<20 and <30 ng/mL) were not different between those with and without psoriasis.

Among those with psoriasis, a multivariate model showed participants with BSA >10 hand palms trended towards lower 25(OH)D compared to those with minimal BSA (-4.98 ng/mL, P = 0.07).

PLI was not associated with 25(OH)D, but BMI showed an inverse association with 25(OH)D (coefficient = -0.40, P < 0.001).

In summary, dermatologists may consider measures of adiposity as better screening tools for vitamin D deficiency than BSA involvement among psoriatics with mild-to-moderate disease.
