Review Questions

• How does first trimester nausea impact nutritional intake for pregnant individuals?
  • First trimester nausea can significantly affect nutritional intake as it may lead to decreased appetite and aversion to certain foods. Pregnant individuals may struggle to consume adequate calories and essential nutrients during this period due to feelings of nausea. It is important for them to find strategies that help manage these symptoms, such as eating bland foods or incorporating small meals throughout the day to maintain proper nutrition.

Some pregnant individuals find relief by avoiding spicy or greasy foods and opting for ginger or lemon-based products. These strategies aim to minimize discomfort while ensuring that necessary nutrients are still consumed during a time when nausea might otherwise hinder eating habits.
• Evaluate the implications of untreated severe first trimester nausea on maternal and fetal health.
  • Untreated severe first trimester nausea, known as hyperemesis gravidarum, can have serious implications for both maternal and fetal health. It can lead to significant dehydration, electrolyte imbalances, and inadequate nutrition for the mother, potentially resulting in complications such as low birth weight or preterm birth. Additionally, prolonged nutritional deficiencies can negatively affect fetal development, emphasizing the need for early intervention and appropriate management to ensure healthy outcomes for both mother and baby.
