The general medical guidance advises against getting a new tattoo while pregnant due to potential risks to the mother and the developing fetus. Tattooing introduces foreign substances and creates a wound, carrying specific hazards during gestation. While no absolute law prohibits the practice, most healthcare professionals and reputable tattoo artists suggest waiting until after delivery. The risks range from acquiring a serious infection to the systemic exposure of the fetus to unregulated chemical compounds present in tattoo inks.
Infection Risks During Application
The primary safety concern is the risk of acquiring an infection, which is heightened during pregnancy due to the body’s altered immune response. Tattooing involves repeatedly puncturing the skin barrier with needles, creating a direct pathway for bacteria or viruses to enter the bloodstream. Even in professional and licensed parlors, a small chance of contamination exists.
Localized infections, such as cellulitis or those caused by Staphylococcus or Streptococcus bacteria, can become more serious and enter the mother’s bloodstream. A severe systemic infection, such as sepsis, can create significant complications for the pregnancy and pose a direct threat to the fetus. Of greater concern is the transmission of bloodborne pathogens (BBPs) if the tattooing equipment is improperly sterilized or contaminated.
Serious bloodborne infections like Hepatitis B, Hepatitis C, and Human Immunodeficiency Virus (HIV) can be transmitted via contaminated needles. If a mother contracts one of these infections, there is a risk of vertical transmission to the child during pregnancy or at birth. For example, a mother with Hepatitis B has a high probability of passing the infection to her baby without proper treatment, while a mother with Hepatitis C has approximately a six percent chance.
Systemic Effects of Tattoo Pigments
Beyond the risk of infection, a concern involves the chemical composition of the tattoo inks themselves. Tattoo inks are not subject to the same regulatory oversight as food or drugs by the Food and Drug Administration (FDA) in the United States, meaning their ingredients are largely unregulated. Many inks contain industrial-grade pigments, including heavy metals like lead, mercury, cadmium, and arsenic, as well as organic dyes often used in printer toners or car paint.
When ink is deposited into the dermal layer of the skin, these particles can enter the lymphatic system and the bloodstream. While the effects of these chemicals on a developing fetus are not well-studied, they could cross the placental barrier. Exposure to heavy metals during pregnancy has been associated with toxic effects on the fetus, including impaired brain development and increased risk of complications like miscarriage or stillbirth.
The introduction of these foreign chemical compounds can also trigger an inflammatory response or an allergic reaction. Since the maternal immune system is adjusted during pregnancy, an intense inflammatory response could create additional stress on the body. Because the first trimester is a time of organ development for the fetus, exposure to potentially toxic substances during this period is of concern.
Physical and Logistical Considerations During Pregnancy
The physical changes of pregnancy present practical reasons to postpone getting a new tattoo. Hormonal shifts can make the skin more sensitive, itchy, or prone to irritation, increasing the chance of an adverse reaction. Furthermore, rapid weight gain and stretching, particularly across the abdomen, hips, and breasts, can permanently distort the appearance of a new tattoo.
A tattoo placed in an area prone to expansion, such as the lower torso, may lose its original sharpness and symmetry; deep stretch marks can permanently damage the ink spread. The timing is also important: the first trimester carries the highest risk for fetal exposure to toxins, and the third trimester is complicated by increased swelling and discomfort. The stress and pain associated with the procedure could also be amplified.
A common medical caution involves tattoos on the lower back, where an epidural may be administered during labor. The theoretical risk is that the epidural needle could core out a fragment of pigmented skin and carry it into deeper tissues, possibly causing neurological complications. While this remains a theoretical concern with no reported complications, anesthesiologists often take precautions, such as inserting the needle through an untattooed area or making a small incision to avoid the pigment.
