Taste, smell and food-related nausea and vomiting responses in hyperemesis gravidarum: A case-controlled study

Abstract

also associated with decreasing prudent diet score from before to early pregnancy, such that women with severe nausea had prudent diet scores 0.29 SDs lower than those with no nausea (P < 0.001) 23 .

Rating of four different foods in women with hyperemesis gravidarum: a randomised controlled trial

“…These findings supported the findings generated from a questionnaire study from our centre that favoured fruits in women with HG. 15 Recorded intolerant responses to the foods tasted also showed that apple had the fewest adverse responses (with no vomiting, the worst response) and bread the most, the trend analysis was significant at the 5% level and consistent with the agreeability and nausea score data.…”

“…22 25 A study done in our centre obtained questionnaire-based responses from patients with HG and found that fewer were likely to feel nauseated or want to vomit when they considered eating apples (16%, which topped the tolerated list), followed by watermelon (21%), oranges (23%), banana (27%) and white bread (31%) compared with eating green vegetables (40%), papaya (42%), chicken (52%) and plain rice (71%). 15 The oft recommended dry cracker made 40% feel nauseated when they considered consuming them. The study also finds that imagined consumption of crunchy-textured and sweet foods was least likely to evoke a nauseous or vomit response.…”

“…Direct testing of the same HG affected women in the same study with taste sticks showing that sweet taste is best and bitter taste worst tolerated. 15 We evaluated the feasibility of our food taste trial design in women with HG and the empiric response towards four common foods including two, apple and watermelon, that topped our questionnaire for tolerability and to crackers and bread, which were often touted as tolerated foods in HG. The data might provide an evidence base to dietary advice in HG.…”

“… 13 Women affected by HG report not being taken seriously by caregivers, pressure for them to eat, lack of early intervention to prevent dehydration and the importance of a single room in the hospital to avoid stimuli that evoked vomiting, like light, noise and smells, in particular food, but also body odour and perfumes. 14 Taste and smell capability are impaired in HG, with smell more affected, 15 but how the impairments may impact food and drink tolerances is not known.…”

A comparison of the efficacy and safety of traditional Chinese medicine external treatment for the hyperemesis gravidarum

“…[ 2 ] 0.3% to 3.6% of pregnant women will have more severe symptoms and usually require hospitalization, although nausea and vomiting of pregnancy are common and not serious usually. [ 3 ] This is called hyperemesis gravidarum (HG) characterized by persistent, severe nausea, and vomiting during pregnancy, which can lead to dehydration, electrolyte disorders, weight loss, and ketonuria, and affect the quality of life of pregnant women seriously. [ 4 , 5 ] The morbidity of HG varies worldwide because of diagnostic criteria and ethnic differences.…”
