Abstract
Obesity is defined as a pathologic state of excess adipose tissue for
the size of the body. Morbidity and mortality in obese population is
significantly more than the normal weight individuals. It has become a
major public health problem in Egypt, with marked rise over the past 30
years. With nearly 70 % of its adult population overweight or obese,
Egypt is the fattest African country and is the 14th fattest country in the
world.
The effects of obesity are a result of two factors: greater adipose
tissue mass and the secretion of various peptides from enlarged fat cells.
The products released from enlarged fat cells include peptide hormones,
cytokines and paracrine transmitters which may lead to various disorders
such as hyperinsulinemia, androgen excess, inflammation and endothelial
dysfunction.
So, obesity can alter skin physiology, leading to changes in the skin
barrier, sweat glands, collagen structure and wound healing, as well as
alterations in inflammation and sebum production.
Moreover, obesity has been implicated in a wide spectrum of
dermatological diseases including AN, skin tags, keratosis pilaris, striae
distensae, hyperandrogenism and hirsutism, lymphodema, chronic venous
insufficiency, plantar hyperkeratosis, skin infection, intertrigo, psoriasis,
HS, tophaceous gout and insulin resistance syndrome.
The aim of this work was to describe the pattern of cutaneous
diseases among obese patients in sample of 212 Egyptian obese patients

was found in 7.5% of females and 4.6% of males.
Psoriasis was found in 14.6 % of studied group. It was found in 10.2%
of females and 24.6% of males.
Atopic dermatitis was found in 8% of the studied group. Varicose veins
were found in 4.7 % of the studied group. Stretch marks were found
83.5 % of the studied group. In addition to 10.4% of the studied group
complains of delayed wound healing by hospitalization.
