Why Does Anxiety Cause Heartburn?

Heartburn typically refers to a burning sensation in the stomach and the area behind the sternum. Some patients with anxiety disorder experience this symptom, primarily because anxiety disrupts autonomic nervous system function, leading to dysregulation of gastric smooth muscle—organs under autonomic control. Thus, heartburn is merely an accompanying symptom of anxiety disorder. A detailed analysis follows:

In patients with anxiety disorder, the nervous system remains in a state of heightened tension, triggering the body’s stress response. This leads to increased gastric acid secretion, potentially causing acid reflux into the esophagus and resulting in heartburn. Additionally, anxiety may impair gastric blood circulation and alter hormonal balance, further exacerbating heartburn symptoms. Anxiety disorder is commonly accompanied by other manifestations, including unexplained worry, restlessness, fatigue, dizziness, chest tightness, and excessive sweating.

Treatment for anxiety disorder may include pharmacotherapy, such as diazepam compound tablets, estazolam tablets, or alprazolam tablets—prescribed under a physician’s guidance. Psychological interventions can also be highly effective: cognitive-behavioral therapy (CBT), which helps patients modify negative thought patterns and maladaptive behavioral responses to anxiety-provoking situations; exposure therapy, gradually confronting anxiety-inducing stimuli to reduce avoidance behaviors; psychodynamic therapy, exploring and resolving deep-seated internal conflicts and underlying sources of anxiety; and mindfulness meditation and other relaxation techniques, which enhance present-moment awareness of emotions and experiences and foster calmness under stress.

Patients with anxiety disorder are advised to drink ample water, avoid greasy and spicy foods, and consume one glass of low-fat milk daily—this regimen has been shown to effectively alleviate anxiety symptoms.
