Pregnancy is a wonderful time in a woman's life. One aspect of
child-bearing , however, may not be so welcomed. For 75-90% of
pregnant women, stretch marks, or striae gravidum, can appear in
the later half of pregnancy. Stretch marks do not pose any
health risk to either the mother or child, but can cause anxiety
over their appearance for those who develop them. Stretch marks
first appear as raised striations which vary in colour from
pink, purple or brown, depending on the mother's normal skin
colour. Striations develop where fat is stored in the body, such
as the abdomen, thighs, hips, buttocks, breasts and arms.
Stretch marks develop during pregnancy because of rapid and
excessive weight gain in areas such as the lower abdomen or
thighs. As weight increases, the collagen and elastin in the
dermal layer of the skin, responsible for retaining shape and
firmness, is stretched to the point of breaking. The dermis is
the layer beneath the epidermis, or visible layer of the skin.
The elastic fibres in the dermis weaken with stretching and
increased cortisone levels normally produced in the last
trimester. As these fibres separate and the skin stretches,
collagen is overproduced to form scar tissue which result in
striations.
There is no cure for stretch marks. The scarring process that
has occurred in the dermis cannot be reversed, but stretch marks
will flatten, fade and lighten over time. Creams which contain
steroids such as hydrocortisone, or active agents like tretinoin
(retin-A) should not be used during pregnancy, and especially
not during the first trimester when the fetus is highly
vulnerable. Plastic surgery methods are available to reduce the
appearance of stretch marks, such as dermabrasion or laser, but
treatments are expensive and results vary.
Genetics play a role in whether a pregnant woman will develop
stretch marks, but equally influential factors are the condition
of the skin and nutrition in determining the onset and severity
of stretch mark development. Well-hydrated and healthy skin
stretches more easily, so drinking plenty of fluids and eating
foods rich in vitamin C, vitamin E, zinc and silica, a component
in collagen formation, are beneficial.
Lotions, creams and other topical treatments will not reach the
dermis, but they can help relieve the itchiness or dryness
associated with stretch marks. Keeping the skin moisturized
decreases any discomfort that may be felt and if stretch marks
are treated when they first appear, their appearance may be
reduced significantly. Massaging nutrient-rich natural oils such
as wheatgerm, jojoba or vitamin E can help heal the epidermis
and also increase blood circulation to the affected area,
assisting the healing process. Pregnant women should avoid
products containing clary sage, basil, cinnamon or thyme, as
these might adversely affect the fetus.
Stretch marks eventually fade and become less obvious over
time. Maintaining a balanced perspective about stretch marks can
keep pregnancy a most precious time for mother and baby.
