Filter by:The goal of this observational study is to learn more about the relation between anxiety (assessed by GAD-7 questionnaire) and the nausea and vomiting in pregnancy (objectively measured by PUQE score). Participants will answer 2 questionnaires: (GAD-7) for anxiety; and (PUQE score) for nausea and vomiting.
Effect of Implementing Ottawa Nutritional Guidelines on the Course of Nausea and Vomiting During Pregnancy (A Randomized Control Trial)
One of the most common discomforts in early pregnancy is nausea and vomiting. Although its etiology is not known exactly, it affects an average of 50-90% of pregnant women. The severity of nausea-vomiting can vary from person to person, as well as in different pregnancies of the woman. The severity of nausea-vomiting is affected by hormonal, psychological and social factors. Adaptation to pregnancy, spouse relations, future anxiety and social support perception in nausea and vomiting experienced during early pregnancy affect women negatively and cause anxiety. The severity of nausea and vomiting also increases due to anxiety. As the severity of nausea-vomiting increases, the search for solutions to this situation and their applications to health institutions increase. Many non-pharmacological methods (respiratory exercises, acupuncture, acupressure, etc.) are used in treatment, as well as hydration, rest and pharmacological agents. One of these methods is the emotional liberation technique, which is included in cognitive behavioral therapies. This method basically treats the person physiologically and psychologically as a whole, similar to other cognitive behavioral therapies, unless there is a physiological disorder. It is aimed to reach a solution by raising awareness for the emotion felt, avoiding negative emotions and focusing on affirmations to replace them. Emotional liberation technique is an easy-to-apply and fast-solving technique in cases recorded in the subconscious with negative emotions and in the treatment of stress disorders in general. No use of emotional liberation technique has been found in the literature for the severity of nausea-vomiting and anxiety experienced during early pregnancy. Therefore, it is thought that this study will contribute to the literature. In addition, it is thought that this method will enrich midwifery interventions as a non-pharmacological method applied to pregnant women in the treatment of nausea-vomiting and anxiety, because this method is fast and practical, and the result is easy to reach. The aim of this study is to determine the effect of emotional liberation technique applied during early pregnancy on nausea and vomiting severity and anxiety.
Between fifty and eighty percent of pregnant women experience nausea and vomiting in pregnancy making it one of the most common medical complications of pregnancy. Hyperemesis gravidarum is an extreme form of nausea and vomiting of pregnancy and results in evidence of acute starvation (i.e. large ketonuria), and weight loss (>5% of a woman's pre-pregnancy weight). Hyperemesis gravidarum is also surprisingly common. In fact, it is the second leading cause of preterm hospitalization during pregnancy, second only preterm labor. Hospitalization is often required because hyperemesis is frequently refractory to common anti-nausea medications. However, capsaicin cream, a potent TRPV1 agonist, commonly used to relieve muscular and neuropathic pain, may be able to reduce the symptoms of nausea and emesis in patients with nausea and vomiting of pregnancy. Smaller studies have demonstrated capsaicin to be both safe and effective when used to treat intraoperative nausea during cesarean delivery. To begin to address whether capsaicin cream could be used to reduce preterm admissions and shorten emergency room visits for hyperemesis, this study will randomize women presenting to the emergency room for nausea and vomiting to treatment with capsaicin cream as an adjunctive medication or routine care. The project will investigate the impact of capsaicin cream on hospital length of stay as well as representation for additional treatment. If effective, capsaicin cream has the potential not only to reduce emergency room visits, hospital admissions and overall health care costs, but also to drastically improve patient quality of life.
Nausea and vomiting is a common complication of pregnancy and occurs in 70-80% of all pregnancies. The symptoms usually start 2-4 weeks after fertilization and peak between the 9th and 16th week of gestation. In the 22nd week of pregnancy, the symptoms usually resolve. In up to 10% of all pregnancies nausea and vomiting may persist until delivery, which is called emesis gravidarum. In 0.3-2% of all pregnancies, nausea and vomiting occur with a pathological intensity called hyperemesis gravidarum. The cause of nausea and vomiting during pregnancy is unknown, but it is believed that the stimulus is the placenta and not the fetus. Antihistamines have proven to be an effective therapy. Histamine is increasingly produced during pregnancy by mast cells in the endometrium and myometrium, but also by mast cells in the placenta and in the decidua. High expression of the histamine-producing enzyme histamine-decarboxylase (HDC) in the placenta and many histamine receptors at the feto-maternal transition in the decidua indicate a physiological role of the histamine during pregnancy. The antidote is diamine oxidase (DAO), which is produced in the decidua and trophoblast and breaks down histamine. DAO acts as a barrier to prevent excessive passage of histamine into the maternal and fetal circulation. DAO levels increase exponentially in the first 20 weeks of pregnancy to 1000 times the baseline before pregnancy. It has been shown that intravenous vitamin C significantly reduces blood histamine levels in both allergic and non-allergic disorders. Another study with the German Navy also proved that oral vitamin C administration can reduce nausea in seasickness. In an Australian study in 2016, it was shown that chewing gum was not inferior to ondansetron therapy in patients with postoperative nausea and vomiting (PONV). From the available literature, we conclude that high maternal histamine concentrations in early pregnancy may be a cause of nausea and vomiting, whereas DAO is not sufficiently expressed by the transfer of histamine from the decidua and trophoblast into the maternal circulation prevent. Vitamin C has been identified in controlled clinical trials as a way to lower blood histamine levels. Furthermore, chewing gum was already described as a treatment option for nausea and vomiting. The aim of this study is therefore to test whether chewing gum containing vitamin C in pregnant women with emesis gravidarum has the potential to reduce nausea and vomiting and to evaluate a possible association between maternal human chorionic gonadotropin (hCG) or histamine levels and the severity of nausea and vomiting in early pregnancy as well as the influence of other factors such as thyroxine and pyridoxine.
The purpose as well as the aim of this project is to understand the effect of probiotics on gastrointestinal (GI) dysfunction such as nausea, vomiting, and constipation that are found during the first and second trimesters of pregnancy. The primary objective of this project is to uncover whether probiotics have an effect on GI functional disorders. The secondary objective is to identify the microbiota associated with probiotic intake. The tested hypothesis is that gut microbiota influences the GI functions and may influence constipation, nausea, and vomiting during pregnancy.
