Bleeding before childbirth is that which occurs after 24 weeks of pregnancy. [4] Bleeding may be vaginal or less commonly into the abdominal cavity. Bleeding which occurs before 24 weeks is known as early pregnancy bleeding. Causes of bleeding before and during childbirth include cervicitis, placenta previa, placental abruption and uterine rupture.
Some researchers speculate the cause to be dependent on dilution, decreased production of platelets, or an increased turnover event. [2] Although women with normal pregnancy experience a low platelet count, women experiencing a continuous drop in platelet will be diagnosed with thrombocytopenia and women with levels greater than 70,000/μL will ...
Certain medications can alter the number and function of white blood cells. [citation needed] Medications that can cause leukopenia include clozapine, an antipsychotic medication with a rare adverse effect leading to the total absence of all granulocytes (neutrophils, basophils, eosinophils).
Some individuals with thrombocytopenia may experience external bleeding, such as nosebleeds or bleeding gums. Some women may have heavier or longer periods or breakthrough bleeding. Bruising, particularly purpura in the forearms and petechiae in the feet, legs, and mucous membranes, may be caused by spontaneous bleeding under the skin. [8] [9]
This can cause irregular periods, as well as thinning hair, acne, and weight gain. Ovarian cysts: Ovarian cysts are sacs filled with fluid or tissue on the ovaries. Most cysts are benign but some ...
This causes a reduction in the fetus' stores of glycogen and lipids. This often leads to hypoglycemia at birth. Polycythemia can occur secondary to increased erythropoietin production caused by the chronic hypoxemia. Hypothermia, thrombocytopenia, leukopenia, hypocalcemia, and bleeding in the lungs are often results of IUGR. [5]
Pregnancy after the age of 35 augments the risk of VTE, as does multigravidity of more than four pregnancies. [2] Pregnancy in itself causes approximately a five-fold increased risk of deep venous thrombosis. [6] Several pregnancy complications, such as pre-eclampsia, cause substantial hypercoagulability. [2]
There are also two general causes of cytopenia: autoimmune and refractory. Autoimmune cytopenia is caused by an autoimmune disease when your body produces antibodies to destroy the healthy blood cells. Refractory cytopenia is caused by bone marrow not producing healthy blood cells, and can be a result of cancer.
