The following are the most important diseases or complications that may be contributed to by hyperemesis gravidarum (vomiting of pregnancy):
Respiratory system (J00-J99)
- Pneumothorax (gas chest; presence of air in the gap between the lung and pleura, causing lung collapse) – as part of Mallory-Weiss syndrome, see “Mouth, esophagus, stomach, and intestines”
Certain conditions originating in the perinatal period (P00-P96).
- Fetal growth retardation (fetal growth disorder → a weight that is too low with respect to the gestational period).
Endocrine, nutritional, and metabolic disorders (E00-E90).
- Alkalosis due to HCl loss (loss of gastric acid) and hypokalemia (potassium deficiency).
- Metabolic acidosis (metabolic acidification of the blood) due to lack of food intake.
Mouth, esophagus (esophagus), stomach, and intestines (K00-K67; K90-K93).
- Mallory-Weiss syndrome – longitudinal (elongated) tears of the mucosa (mucous membrane) and submucosa (submucosal connective tissue) of the esophagus occurring more frequently in alcoholics, which may be associated with potentially life-threatening hemorrhage of the external esophagus and/or gastric inlet (gastrointestinal hemorrhage/GIB) as a complication.
- Esophageal rupture – tear in the wall of the esophagus caused by severe vomiting.
Liver, gallbladder and bile ducts – pancreas (pancreas) (K70-K77; K80-K87).
Psyche – nervous system (F00-F99; G00-G99).
- Neuropathy (nerve damage), unspecified.
Pregnancy, childbirth, and puerperium (O00-O99).
- Preeclampsia (condition occurring in pregnancy and associated with symptoms of edema (water retention in tissues), proteinuria (increased excretion of protein in urine), and arterial hypertension (high blood pressure)) – induced by exsiccosis (dehydration: loss of fluid and salt), hypovolemia (lack of volume), and hemoconcentration (thickening of blood).
