Gestational diabetes shows several symptoms, the most typical being the "three more one less" syndrome, namely increased thirst, increased appetite, urination, and weight loss. The second common manifestation is fatigue, which is due to glucose not being utilized effectively in the body and being broken down too quickly, leading to insufficient energy replenishment. The third is unexplained frequent fungal infections, such as recurring candidal infections of the vulva and vagina, at which point blood sugar screening should be considered. The fourth symptom is pregnancy accompanied by excessive amniotic fluid or a large fetus. The fifth is glucose positivity in urine from two fasting morning samples.
