What is Pica Disorder?

Pregnancy Dangers

During pregnancy, a women’s health status has a tremendous bearing on her body’s ability to nurture, grow and deliver a healthy baby. While nutrient deficiencies may well develop during this time due to the strain pregnancy places on the body, eating nonfood items on a regular basis can impair the body’s systems in any number of ways. When this happens, the risk of having pregnancy and delivery complications increases.

In effect, the materials contained in nonfood substances can impair the body’s digestive processes and prevent needed nutrients from being absorbed from “real” food. Nonfood items like sand, dirt and clay may also contain metal deposits or even lead, which can lead to toxic poisoning over time.

Nonfood materials may also create blockages in the digestive tract and cause cramping, pain or chronic constipation. Also of concern is the likelihood of ingesting bacteria and parasites, both of which can cause harmful infections to develop.
