These fluids include water, ginger‐flavoured drink, orange juice and lemon drink (water and ginger‐flavored drink are compulsory, whereas orange juice and lemon drink are the 2 top ranking fluids based on the first part questionnaire). 1. Patient admitted to Gynecology ward UMMC with presumed diagnosis of hyperemesis gravidarum. 2. Screening of patient is done with the Eligibility Form (EF) and patients who fulfill the inclusion and exclusion criteria are approached for recruitment. 3. Patient will be provided with a Patient Information Sheet (PIS) and a verbal explanation of the study. 4.

Fluid tasting requires the swallowing of a liquid measured accurately with a syringe of 30 ml per serving in a standard 50ml disposable cup. 8. In the presence of the investigator, participants are required to take each drink, hold it for 3 seconds and rinse it in the mouth, then slowly swallow. This is repeated for the 4 fluid items in a randomly allocated order and observed for 10 minutes after each fluid item. 9. Participants will be required to rinse their mouth with plain water at the end of tasting each fluid item before proceeding to the next fluid item. Drinking plain water at any time during the tasting is allowed as well. 10. Participants will be asked to score the severity of their nausea in a visual numerical rating score from 0‐10.
