Although the CDC states that pregnant women are 20 times more likely to become infected than non-pregnant healthy adults, the number of cases of listeriosis in pregnant women is about 17% . Symptoms of listeriosis may show up 2-30 days after exposure. Symptoms in pregnant women include mild flu-like symptoms, headaches, muscle aches, fever, nausea, and vomiting. If the infection spreads to the nervous system it can cause stiff neck, disorientation, or convulsions.
Hypothyroidism in Pregnancy. Newly diagnosed hypothyroidism in pregnancy is rare because most women with untreated hypothyroidism do not ovulate or produce mature eggs in a regular manner, which makes it difficult for them to conceive. It is a difficult new diagnosis to make based on clinical observation. The signs and symptoms of hypothyroidism (fatigue, poor attention span, weight gain, numbness, and tingling of the hands or feet) are also prominent symptoms of a normal pregnancy. Undiagnosed hypothyroidism during pregnancy increases the chance of stillbirth or growth retardation of the fetus.
