A hernia can start as a small, painless bulge that is easy to ignore. While this can seem harmless, it is important to know that the next step of hernia evolution is aching, burning or pressure that interferes with daily life and can and will become a medical emergency.
That is why it is imperative to know and recognise the signs and help you plan the next step and decide when to book an appointment and when to seek care immediately.
Here we will cover what a hernia is, what the most common symptoms are, the different types of it, which warning signs need urgent attention, and how doctors confirm a diagnosis.
While we discuss all of these things, remember that this is just a general introduction and not a substitute for an examination by a qualified healthcare professional.
What Is a Hernia?
First things first, let’s cover what a hernia actually is. A hernia is the bulging of an organ or tissue through an irregular opening, typically in the belly.
In most abdominal hernias, part of the intestine or a piece of fatty tissue pushes through a weak spot in the abdominal wall, more commonly known as ‘abs’ – the layer of abdominal muscle and connective tissue that normally holds your organs in place.
Hernias develop where the abdominal wall muscles are naturally thinner or have been weakened due to strain or injury. Common issues that will cause this include:
- Pressure on the abdomen – Heavy lifting, persistent hard coughing, straining during bowel movements or urination, and general pregnancy issues
- Weakened tissue – Age, previous surgery, and congenital weak spots
- Other loosely common factors – Obesity, smoking, and chronic conditions that affect tissue strength
Generally, the most common triggers that cause hernias are activities that are heavy-hitting for the body, pregnancy, and chronic hard coughing.
Also, very important to know is that hernias do not heal on their own. Some small ones cause few problems and are monitored over time, but the opening in the muscle wall does not close without surgical repair.
Common Symptoms of a Hernia
Symptoms depend on the hernia’s location and size, but several signs appear across most abdominal wall hernias.
A visible or palpable bulge
This is the hallmark sign that is easiest to acknowledge and realise what is happening. You may see or feel a lump anywhere in the groin, near the belly button, or along the abdomen.
It will surely become more noticeable when you stand, cough, strain or lift, and may shrink or disappear when you lie down. If you can gently press back the bulge, which we do not recommend, we call these hernias “reducible”.
Aching, burning or pressure at the site
Many people describe a dull ache or a feeling of exhaustion and fatigue, particularly toward the end of the day and/or after physical effort.
Pain with activity
Discomfort that increases when you lift, bend, cough or exercise is a typical pattern that something is clearly wrong with your abdomen wall. Some people often describe a strange dragging or pulling sensation, especially when groin hernias are in question.
Not every hernia causes symptoms. Some are found incidentally during a routine exam or imaging for other illnesses, which is one more reason why a total clinical examination matters and should be done regardless of the issues you experience.
Types of Hernias and How Their Symptoms Differ
Now talking about the types of hernia will help to explain why symptoms can vary and what dangerous is your hernia for your health.
Inguinal hernia
This is the most common type of abdominal wall hernia. It appears as a bulge in the groin where the thigh meets the lower abdomen, and it occurs far more often in men than in women.
In men it can extend toward the scrotum, sometimes causing swelling there. Discomfort typically worsens with standing, straining or lifting.
Femoral hernia
Femoral hernias occur just below the groin crease, in the upper thigh area, and are more common in women, particularly older women. They are less common than inguinal hernias but are more likely to cause complications, so they are often repaired promptly.
Umbilical hernia
An umbilical hernia forms at or near the navel. It is common in infants, where these pass often without treatment, but it can also affect adults. Examples of this hernia can happen, especially after pregnancy, with obesity, or with repeated pressure on the abdomen.
Incisional hernia
An incisional or Richter hernia develops in the places of the body that have been affected in a previous abdominal surgery, where the healed incision has not fully regained its strength.
It may appear weeks, months or years later. If you’ve had abdominal surgery, look out for hernia symptoms.
Hiatal hernia
Unlike the others, a hiatal hernia occurs inside the body. What happens is that part of the stomach pushes up through the diaphragm into the chest cavity. There is usually no visible bulge, which is why it is hard to detect at first.
Instead, people may notice heartburn, acid reflux, regurgitation, chest discomfort or difficulty swallowing. Because these symptoms overlap with conditions of other illnesses, a medical evaluation is the only way to tell if it’s a hernia or not.
Epigastric and other ventral hernias
Epigastric hernia and similar ventral hernias appear in the midline of the upper abdomen, between the breastbone and navel, and show up as a small, sometimes tender lump.
Warning Signs That Need Urgent Medical Attention
There are two dangerous complications turn a hernia from a simple medical issues into full blown emergency.
- Incarceration – The protruding tissue becomes trapped and cannot be pushed back into the abdomen.
- Strangulation – The trapped tissue loses its blood supply. A strangulated hernia can be life-threatening if it isn’t treated. An incarcerated hernia is a surgical emergency and requires hernia repair surgery.
In the same manner of importance, if you have a known or suspected hernia, the symptoms that you should seek emergency care are any of the following:
- Sudden, severe or rapidly worsening pain at the hernia site
- A bulge that becomes firm, tender and cannot be pressed back in
- A bulge that turns red, purple or dark
- Nausea, vomiting or a swollen abdomen
- Fever or a racing heartbeat
- Inability to pass stool or gas
These can signal a bowel obstruction or compromised blood flow. Do not wait to see whether symptoms improve.
When to See a Doctor for a Non-Urgent Hernia
Book a routine appointment if you notice a new lump in your groin, abdomen or navel.
Even if it doesn’t hurt, or if you have a recurring ache that worsens with activity. Early evaluation lets your doctor identify the type, discuss options and set a plan for monitoring or repair before complications occur.
How Doctors Diagnose a Hernia
Diagnosis usually begins with a conversation and a physical exam.
- Medical history – Your clinician will ask when you first noticed the bulge, what makes it feel better or worse, whether you have pain, and about your surgical history, job demands, lifting habits, and chronic cough or constipation.
- Physical examination – For visible hernias, the exam is often enough. The clinician examines the area while you stand and may ask you to cough or bear down, which raises abdominal pressure and makes a bulge more apparent. They will also check whether it can be gently pressed back in.
- Imaging – If the diagnosis is uncertain, the hernia is small or deep, or the person has significant obesity or pain without a clear bulge, imaging can help. Ultrasound is a common way to find out and uses no radiation. CT or MRI can show more detail, particularly in complex or recurrent hernias.
- Tests for hiatal hernia – Because there is no external bulge, diagnosis may involve a barium swallow X-ray or an upper endoscopy, in which a thin camera examines the esophagus and stomach.
What Happens After a Diagnosis?
Treatment depends on the hernia type, your symptoms, and your overall health. Some small, minimally symptomatic hernias can be watched over time. Others are repaired surgically, either through an open incision or with minimally invasive techniques.
Your surgeon will discuss what suits your situation. Our guides on recovery after hernia surgery and returning to exercise cover what comes next, so for any more information, check out our website and clinic.
