Obesity affects over 40% of U.S. adults. Carrying extra weight not only raises the risk of heart disease and diabetes—it also makes hernias more likely. A hernia is when an organ or tissue pushes through a weak spot in muscle. Below, we explain how excess weight leads to hernias, what warning signs to watch for, and ways to prevent them.
Why Obesity Raises Hernia Risk
More Pressure Inside Your Belly
Extra fat presses on the abdominal wall.
Muscles stretch and weaken over time.
Weaker Muscle and Tissue
Obesity often goes hand in hand with low muscle tone.
Poor connective tissue makes the wall less sturdy.
Slower Healing After Surgery
Fat tissue has less blood flow, slows recovery.
Raises the chance of hernias at surgical scars.
Hernia Types Linked to Obesity
Hiatal Hernia: Belly fat pushes part of the stomach up through the diaphragm.
Umbilical Hernia: Pressure around the navel area forces tissue out.
Incisional Hernia: Forms at past surgery sites, more common if you have a high BMI.
Common Signs of Obesity-Related Hernias
A visible bulge in your belly or groin, worse when you stand or strain.
Pain or soreness around the bulge, especially after activity.
Digestive troubles like nausea, vomiting, or heartburn (hiatal hernias).
In severe cases, blocked bowel movements, which can become life-threatening.

How to Lower Your Risk
Lose Weight
Even 5–10% weight loss cuts belly pressure.
Builds up your core strength over time.
Stay Active
Choose low-impact exercises like walking or swimming.
Do gentle core moves, such as planks or bridges.
Lift Safely
Bend at your knees, not your back.
Ask for help with heavy items.
Treatment Options
Lifestyle Changes: A balanced diet, regular exercise, and quitting smoking can ease symptoms and help you heal after surgery.
Medications: For hiatal hernias, drugs can cut down on acid reflux.
Surgery: The choice of open or laparoscopic repair depends on the hernia’s size and your overall health.
