O26.643
Intrahepatic cholestasis of pregnancy, third trimester
Clinical Classification Guidelines
Medical Intelligence & Overview
Intrahepatic cholestasis of pregnancy (ICP) is a liver disorder that occurs during pregnancy, typically in the third trimester. Characterized by a reduction in bile flow within the liver, ICP can lead to a build-up of bile acids in the bloodstream. This condition most often presents with itching and can pose risks for both the mother and the developing baby. Proper understanding and management are essential for monitoring and minimizing complications associated with ICP.
Causes & Symptoms
Clinical Causes: Hormonal changes during pregnancy, especially elevated levels of estrogen and progesterone Genetic predisposition, as women with a family history of cholestasis are at higher risk Pre-existing liver conditions or bile duct obstructions Age and ethnicity factors, with higher incidence noted in women of Scandinavian or South American descent Environmental factors that may influence liver function
Key Symptoms: Intense itching, especially on the palms of the hands and soles of the feet Skin rash or discoloration Dark urine and pale-colored stools Fatigue or general feeling of malaise Potential signs of liver dysfunction such as nausea or abdominal discomfort
Diagnostic & Treatment
Diagnosis Path: Diagnosis primarily involves clinical assessment of symptoms and laboratory tests. Blood tests are used to measure elevated bile acid levels and liver function indicators. Healthcare providers may also perform ultrasounds to rule out other liver or gallbladder issues. Because ICP develops during late pregnancy, diagnosis is often made during routine prenatal visits when symptoms are reported.
Treatment Protocols: Medications such as ursodeoxycholic acid to improve bile flow and reduce bile acid levels Monitoring bile acid levels regularly to assess disease progression Frequent fetal heart rate monitoring and ultrasound assessments to detect any signs of fetal distress Delivering the baby early if the risks of continuing pregnancy become significant, often around 37-38 weeks Lifestyle adjustments, including avoiding triggers that worsen itching and staying hydrated
