severe or prolonged vomiting.
"the clinical practicability is limited by a higher degree of side effects, especially hyperemesis"
persistent severe vomiting leading to weight loss and dehydration, as a condition occurring during pregnancy.
TREATMENT:
Modification of the amount and size of meals consumed throughout the day may help relieve symptoms. Having smaller amounts of food and fluids more often can help prevent mild cases of nausea and vomiting from worsening. The meals should contain more carbohydrate than fat and acid.6 Protein-rich meals also decrease symptoms. Lighter snacks, including nuts, dairy products, and beans, are often endorsed. Drinks that contain electrolytes and other supplements are advised. If certain foods or food preparations trigger nausea, they should be avoided.
