Hernia Symptoms: Types, Signs & When to See a Doctor (UK 2026)
Noticed a lump, or worried you might have a hernia? This guide explains the common symptoms and types in plain English, when it’s worth seeing your GP, and — importantly — the red-flag signs that mean you need emergency help. It’s general information only, not a diagnosis: only a doctor can tell you what’s going on.
⚠️ Read this first — when a hernia is an emergency
A strangulated hernia is a life-threatening emergency. Call 999 or go to A&E immediately if a hernia (or a lump) causes: sudden pain that quickly gets worse, a bulge that turns red, purple or dark, nausea or vomiting, or you can’t pass stool or wind. Do not wait, and don’t try to manage it yourself. If you’re unsure, it’s always safer to seek emergency help.
This page is general information only — it is not a diagnosis or medical advice. Many conditions cause similar symptoms. If you have a new lump or ongoing discomfort, please see your GP.
Quick Answer
The most common sign of a hernia is a lump or bulge, usually in the tummy or groin, often more visible when standing, coughing or straining and shrinking when you lie down. Some cause an ache or dragging feeling; a hiatus hernia tends to cause heartburn rather than a lump. Hernias don’t heal on their own.
Only a doctor can confirm whether a lump is a hernia — so a new or changing lump is worth getting checked by your GP. The exception is the emergency signs above (a strangulated hernia), which need 999 or A&E. This page explains the types and symptoms as general information, and points you to help — it does not give a diagnosis or treatment advice.

What a Hernia Is
In simple terms, a hernia happens when part of the inside of the body (often fatty tissue or part of the bowel) pushes through a weak spot in the surrounding muscle or tissue wall, usually in the tummy or groin. That’s what can create a visible or feelable lump. Weaknesses can be present from birth or develop over time with age, strain, heavy lifting, coughing, pregnancy or after surgery. This is background information to help you understand the term — it is not a way to diagnose yourself. If you think you might have a hernia, the right step is to see a doctor who can examine you.
Common Symptoms
Hernias vary, but people commonly describe:
- A lump or bulge in the tummy or groin — often more noticeable when standing, coughing or straining, and often reducing or disappearing when lying down.
- An ache, heaviness or dragging feeling around the area.
- Discomfort when lifting, bending or coughing.
- Some hernias are painless at first and simply noticed as a lump.
- A hiatus hernia is different — it often causes heartburn and acid reflux rather than a visible lump, because it involves the stomach and diaphragm.
Important
These are general descriptions, not a checklist to diagnose yourself with. Plenty of other conditions can cause a lump or abdominal discomfort, some of which need their own attention. The only reliable way to know what’s causing your symptoms is a proper examination by a doctor — please don’t rely on a web page to decide.
Types of Hernia
Hernias are usually named by where they occur. As general information:
| Type | Where | Notes |
|---|---|---|
| Inguinal | Groin | The most common type |
| Femoral | Upper thigh / groin | More common in women; higher risk of getting trapped |
| Umbilical | At/near the belly button | Common in babies; also seen in adults |
| Incisional | Site of a previous operation | Where a surgical wound has weakened |
| Epigastric | Upper abdomen | Between the belly button and breastbone |
| Hiatus (hiatal) | Stomach through the diaphragm | Tends to cause heartburn, not a lump |
Knowing the names doesn’t tell you which, if any, you have — only a doctor can determine that from an examination and, where needed, a scan.
Emergency Warning Signs
⚠️ A strangulated hernia is a 999 / A&E emergency
Occasionally a hernia becomes trapped and its blood supply is cut off — this is called strangulation, and it’s life-threatening and needs urgent surgery. Call 999 or go straight to A&E if you have: sudden pain that quickly worsens · a bulge that turns red, purple or dark · nausea or vomiting · being unable to pass stool or wind. Don’t wait to see if it settles, and don’t try to push it back or manage it at home. If in any doubt, treat it as an emergency — acting fast genuinely matters here.
When to See Your GP
Away from those emergency signs, the sensible step for any new or changing lump, or ongoing tummy/groin discomfort — even painless — is to see your GP. Hernias don’t heal by themselves, and a doctor can examine you, confirm what it is, and talk through the options with you. Getting a lump checked is worthwhile rather than waiting and worrying. If a referral for a scan or a specialist follows, our guide on GP referrals for private treatment explains how that works. To be completely clear: this page cannot tell you whether you have a hernia or what to do about it — that’s a conversation for you and a doctor.
Getting Seen Privately
If you’d rather not wait for an NHS appointment, you can choose to be assessed privately — a private GP or surgeon can examine the area, confirm whether it’s a hernia, and discuss options, often within days. For many hernias the treatment is a planned surgical repair; if that route is relevant to you, our private hernia surgery cost guide covers what that involves and typical prices, with wider context in our private surgery costs and hospital price list guides. Going private here is simply a choice about speed and convenience for a planned assessment — it is not a substitute for emergency care, and a suspected strangulated hernia is always an A&E/999 matter. How private access compares with NHS waits is covered in our NHS waiting times guide.
FAQs: Hernia Symptoms (2026)
What are the common symptoms of a hernia?
The most common sign of a hernia is a lump or bulge, usually in the tummy or groin, that is often more noticeable when standing, coughing or straining and may shrink or disappear when lying down. People also describe an aching or dragging feeling, or discomfort when lifting or bending. Some hernias are painless at first, while a hiatus hernia (where part of the stomach moves up through the diaphragm) tends to cause heartburn and reflux rather than a visible lump. This page is general information only and not a diagnosis. Many other conditions can cause similar symptoms, so if you notice a new lump or ongoing discomfort, the only way to know what it is is to see your GP, who can examine you and arrange any tests needed.
What are the warning signs of a strangulated hernia?
A strangulated hernia is a medical emergency and needs immediate treatment. The warning signs to know are: sudden hernia pain that quickly gets worse, a bulge that turns red, purple or dark, nausea or vomiting, and being unable to pass stool or wind. This happens when the blood supply to trapped tissue is cut off, which is life-threatening if not treated urgently. If you have any of these signs, do not wait or try to manage it yourself: call 999 or go to A&E immediately. This is not something to book a routine appointment for. Even if you are unsure, it is always safer to seek emergency help, because a strangulated hernia can cause serious harm very quickly and usually requires urgent surgery.
What are the different types of hernia?
The main types are named by where they occur. An inguinal hernia is in the groin and is the most common. A femoral hernia is lower, in the upper thigh or groin, is more common in women, and carries a higher risk of becoming trapped. An umbilical hernia is at or near the belly button, common in babies but also seen in adults. An incisional hernia develops at the site of a previous surgical wound. A hiatus (or hiatal) hernia is different, occurring where part of the stomach pushes up through the diaphragm, and tends to cause heartburn rather than a visible lump. An epigastric hernia appears in the upper abdomen. This is general information only, and only a doctor can tell you which type, if any, you have, so see your GP if you are concerned.
When should I see a doctor about a possible hernia?
See your GP if you have a lump or bulge you are unsure about, or ongoing discomfort in your tummy or groin, even if it is not painful. Hernias do not heal by themselves and a doctor can confirm what it is and discuss the options with you, so it is worth getting any new lump checked rather than waiting. This is not urgent in itself, but it should not be ignored either. The exception is the warning signs of a strangulated hernia, sudden worsening pain, a bulge turning red, purple or dark, vomiting, or being unable to pass stool or wind, which are an emergency needing 999 or A&E. This page is general information, not a diagnosis or medical advice, so please speak to your GP about your own symptoms.
Can I get a hernia checked and treated privately?
Yes. If you want to be seen quickly rather than wait for an NHS referral, you can see a private GP or surgeon who can examine the area, confirm whether it is a hernia, and discuss options, which for many hernias is surgical repair. This can mean being seen in days rather than weeks. However, this is only for non-urgent assessment: a suspected strangulated hernia is an emergency for A&E or 999, not a private booking. Going private for a planned hernia assessment is a personal choice about speed and convenience, not a medical necessity for most hernias. Always start with a proper assessment by a doctor, whether NHS or private, rather than assuming what a lump is, as only an examination can confirm the diagnosis.
