O21.1
Hyperemesis gravidarum with metabolic disturbance
Clinical Classification Guidelines
Inclusion Terms
- Hyperemesis gravidarum, starting before the end of the 20th week of gestation, with metabolic disturbance such as carbohydrate depletion
- Hyperemesis gravidarum, starting before the end of the 20th week of gestation, with metabolic disturbance such as dehydration
- Hyperemesis gravidarum, starting before the end of the 20th week of gestation, with metabolic disturbance such as electrolyte imbalance
Medical Intelligence & Overview
Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy. When it is accompanied by metabolic disturbances like dehydration, electrolyte imbalances, or carbohydrate depletion, it requires careful management. This condition typically begins before the 20th week of pregnancy and can impact both the mother and the developing baby. Recognizing the signs and understanding the causes can help in seeking appropriate care.
Causes & Symptoms
Clinical Causes: Hormonal changes during pregnancy, especially elevated levels of human chorionic gonadotropin (hCG) and estrogen Genetic predisposition or family history of severe nausea and vomiting during pregnancy Pre-existing health conditions such as migraines or gastrointestinal issues Psychological factors, including stress or anxiety, which may contribute to symptom severity Nutritional deficiencies or dehydration can worsen symptoms, creating a cycle of worsening health
Key Symptoms: Persistent and severe nausea and vomiting beyond the typical pregnancy-related morning sickness Inability to keep food or fluids down for extended periods Weight loss due to decreased intake and vomiting Dehydration symptoms such as dry mouth, dizziness, and dark-colored urine Electrolyte imbalances causing muscle weakness, irregular heartbeat, or confusion Fatigue and weakness due to carbohydrate depletion and metabolic disturbances Ketone bodies in urine indicating the body is breaking down fat for energy
Diagnostic & Treatment
Diagnosis Path: Diagnosing hyperemesis gravidarum with metabolic disturbance involves a combination of clinical assessment and laboratory tests. Healthcare providers will evaluate symptoms, perform physical examinations, and order tests such as blood work and urinalysis to assess hydration status, electrolyte levels, and ketones. Ultrasound may be used to confirm gestational age and exclude other causes of vomiting. The goal is to identify the severity of dehydration and metabolic imbalance to guide treatment options.
Treatment Protocols: Management of hyperemesis gravidarum with metabolic disturbance focuses on restoring hydration, correcting electrolyte imbalances, and ensuring proper nutrition. Common approaches include: - Intravenous fluids to rehydrate and restore electrolyte balance - Medications to reduce nausea and vomiting, such as vitamin B6, doxylamine, or other antiemetics - Nutritional support, such as small, frequent meals, or intravenous nutrition if oral intake is not possible - Monitoring for complications like electrolyte disturbances or kidney issues - Addressing underlying psychological or hormonal factors In severe cases, hospitalization may be necessary to thoroughly manage dehydration and metabolic problems, and to prevent risks to both mother and baby.
