What causes chest tightness after eating?

Chest tightness after eating is most often caused by digestive issues, but it can also come from the heart.

Common causes include:

• Acid reflux/GERD: stomach acid backs up into the esophagus and can feel like burning or pressure.
• Esophageal spasms: painful squeezing in the food pipe, sometimes triggered by eating too fast or very hot/cold foods.
• Hiatal hernia: part of the stomach pushes up into the chest and can cause fullness or reflux.
• Gallbladder or pancreatic problems: especially after fatty meals, with pain that can spread upward.
• Anxiety or food-related reactions: can add chest tightness or make symptoms feel worse.
• Post-meal angina: a heavy meal can trigger chest tightness if there’s underlying coronary artery disease.

Get emergency care now if the tightness comes with shortness of breath, sweating, dizziness, nausea, or pain spreading to the jaw, neck, back, or arm, or if it lasts more than a few minutes.
