Hiatal Hernia

A hiatal hernia occurs when part of the stomach pushes through the diaphragm into the chest cavity. This condition can vary in severity and may be associated with various digestive symptoms. Understanding hiatal hernia can help individuals make informed decisions regarding lifestyle choices and dietary habits.

  • What exactly is happening when I have a hiatal hernia?
    MedlinePlusMay 2026

    Your stomach is pushing up through an opening in your diaphragm, which is the muscle that separates your chest from your belly. This makes it easier for stomach acid to leak up into your esophagus, causing heartburn and other uncomfortable symptoms.

  • Why does the muscle at the bottom of my esophagus stop working right?
    MedlinePlusMay 2026

    The muscle at the bottom of your esophagus (called the lower esophageal sphincter) normally keeps acid down, but when your stomach pushes through the diaphragm opening, it can't work as well. The exact reason the diaphragm weakens is often unknown, but it may be related to age, injury, or a birth defect.

  • How common are hiatal hernias in people over 50 like me?
    MedlinePlusMay 2026

    Hiatal hernias are very common in people over 50—they happen to a lot of people in that age group. Your risk goes up as you get older because the muscles naturally weaken over time.

  • Can being overweight or smoking make it worse?
    MedlinePlusMay 2026

    Yes, being overweight and smoking both increase your risk of getting a hiatal hernia and can make symptoms worse. Losing weight and quitting smoking may help reduce your symptoms.

  • Is there anything I can do to prevent getting one?
    MedlinePlusMay 2026

    Since the exact cause is often unknown and it's related to muscle weakness that comes with age, there's no guaranteed way to prevent one. However, maintaining a healthy weight and not smoking may lower your risk.
