What causes the vomiting of saliva in the mornings?
Vomiting saliva in the mornings, also known as morning sickness, is a common symptom experienced by individuals, particularly during pregnancy. The main cause of morning sickness is thought to be hormonal changes, specifically an increase in human chorionic gonadotropin (hCG), a hormone produced by the placenta during pregnancy. Other potential causes include:
Increased stomach acid production: Morning sickness can result from increased stomach acid production, which can irritate the stomach lining, leading to nausea and vomiting.
Delayed gastric emptying: Pregnancy hormones can slow down the emptying of the stomach, causing food and saliva to remain in the stomach for longer periods, contributing to nausea.
Hyperplasia of gastric mucosa: The stomach lining can become thicker and more active during pregnancy, which can lead to increased acid secretion and nausea.
Changes in the inner ear: Hormonal changes can affect the inner ear, which is responsible for balance. This imbalance can cause nausea and vomiting.
Low blood sugar levels (hypoglycemia): Morning sickness can occur due to low blood sugar levels, especially if breakfast is skipped or delayed.
