University of California, Davis39 enrolled

Overview

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.

Outcomes

Primary Outcomes

Number of vomiting and nausea per day

Using scale of 1-5, quantify the seriousness of sick to the stomach, dry heaves, fatigue, lack of energy, and feeling blue.

Time frame: 16 days following baseline fecal sample collection

Secondary Outcomes

The relative quantity of gut bacteria at phylum, family, and species level when patients take or do not take Probiotic-10.

To receive at least six (6) analyzable fecal specimens including one prior to taking probiotics from 33 subjects to identify the microbiota associated with probiotic intake.
