Can gastroesophageal reflux disease (GERD) cause dizziness and a feeling of head fullness?

Patients with gastroesophageal reflux disease (GERD) may experience loss of appetite, which can lead to hypoglycemia and subsequently cause symptoms such as dizziness and a feeling of head fullness or pressure. In such cases, treatment should be symptom-directed—typically involving medications that suppress gastric acid secretion, possibly combined with agents that protect the gastric mucosa. Regular monitoring of blood pressure and blood glucose levels is recommended. Additionally, patients should pay attention to dietary control in daily life, avoiding excessive food intake at a single meal.
