Quick answer: Symptoms of diaphragmatic inflammation include chest or upper abdominal pain, difficulty breathing, a high fever and general malaise. The condition is most commonly caused by a bacterial or viral infection and may require a gastroenterological examination to establish an accurate diagnosis.
If you experience chest pain, shortness of breath and a fever all at once, you might easily assume you have a heart problem. In many cases, however, the source of these symptoms is a little-known but all the more unpleasant condition: inflammation of the diaphragm. This large, dome-shaped muscle – which separates the chest from the abdominal cavity – is responsible both for breathing and for the stable functioning of the upper gastrointestinal tract. If, for any reason, it becomes inflamed, the effects can be felt in almost every part of the body.
The symptoms of diaphragmatic inflammation can be misleading. They may resemble those of pneumonia, a stomach ulcer or even a gallbladder problem. This is precisely why it is important to understand what to look out for and when to see a specialist.
In this article, we provide a detailed overview of the symptoms of diaphragmatic inflammation, its possible causes, the diagnostic process, treatment options, and when and why it is advisable to seek a consultation with a gastroenterologist.
What is the diaphragm, and why does it play an important role in digestion?
The diaphragm (Latin: diaphragma) is a large, arched muscle that runs horizontally between the chest and the abdomen. Every time you breathe in, it contracts and moves downwards to make room for the lungs. When you breathe out, it relaxes and returns to its original position.
It plays a particularly important role from a gastroenterological perspective. The oesophagus passes through the diaphragm via an opening (hiatus oesophageus), and the right lobe of the diaphragm acts as an external sphincter alongside the lower oesophageal sphincter (LES). This structure prevents gastric contents from flowing back into the oesophagus.
If this closure mechanism does not function properly – for example, in the case of a hiatal hernia – reflux may develop. In a hiatal hernia, part of the stomach slides up into the chest cavity through the opening in the diaphragm, which can cause heartburn, pain and digestive problems. This condition is closely linked to the health of the diaphragm and requires a gastroenterological examination.
Symptoms of diaphragmatic inflammation – what should you look out for?
The symptoms of diaphragmatic inflammation vary and can affect several organ systems at the same time. We have listed the most common signs below.
Chest and upper abdominal pain
One of the most characteristic symptoms of diaphragmatic inflammation is pain, which occurs in the centre of the chest or in the upper abdomen. This pain:
- It may get stronger when you take a deep breath
- It may get worse when you cough or sneeze
- It may radiate into the shoulder (particularly on the left side)
- It can persist even at night, making it difficult to sleep
Difficulty breathing
As the diaphragm is directly involved in breathing, inflammation of this muscle may also affect breathing. Typical symptoms include:
- Shortness of breath or a feeling of tightness in the chest
- Shallow, rapid breathing
- Pain when taking a deep breath
- Worsening of symptoms when lying flat
Fever and general malaise
If the inflammation is caused by a bacterial or viral infection, systemic symptoms may also occur:
- High body temperature (above 38 °C)
- Chills, sweating
- General weakness, fatigue
- Loss of appetite
Digestive complaints and gastroenterological symptoms
The diaphragm is anatomically linked to the gastrointestinal tract, so inflammation of the diaphragm may also cause digestive symptoms:
- Nausea, and occasionally vomiting
- Bloating, feeling full after eating
- Heartburn, acid reflux
- Difficulty swallowing (dysphagia)
- Loss of appetite
These symptoms become particularly pronounced when inflammation of the diaphragm is associated with a hiatal hernia. In such cases, the upper part of the stomach slides up into the chest cavity, which exacerbates reflux symptoms and increases the risk of damage to the mucous membrane.
What causes inflammation of the diaphragm?
There may be various underlying causes for the symptoms of diaphragmatic inflammation. The most common ones are set out below.
Bacterial and viral infections
Inflammation of the diaphragm is a relatively rare condition, most commonly caused by infectious agents. Both bacteria and viruses can affect the diaphragm, particularly if neighbouring organs (the lungs, liver or the space beneath the diaphragm) are infected. In cases of pneumonia, pleurisy or a subphrenic abscess, the inflammation may spread to the diaphragm.
Hiatal hernia and gastroenterological associations
Diseases of the diaphragm and disorders of the upper gastrointestinal tract are closely related. A large hiatal hernia can cause mucosal damage (Cameron lesions) due to mechanical and ischaemic factors, which may also lead to upper gastrointestinal bleeding. Reflux oesophagitis is also closely associated with insufficiency of the diaphragmatic sphincter.
Other contributing factors
Inflammation of the diaphragm can, less commonly, be caused by other factors:
- Trauma: Following a chest or abdominal injury, the diaphragm may be directly affected
- Surgical intervention: Following heart, lung or liver surgery, the diaphragm may be affected by the inflammatory process
- Autoimmune diseases: Certain systemic inflammatory conditions can also affect the diaphragm
- Endometriosis: In rare cases, the endometrial tissue may extend to the diaphragm, causing cyclical chest pain
How is diaphragmatic inflammation diagnosed?
The symptoms of diaphragmatic inflammation can resemble those of many different conditions, so establishing an accurate diagnosis is a multi-step process.
Medical history and physical examination
The doctor will first ask detailed questions about the symptoms: when they began, how they change with breathing, whether there is a fever, and what digestive symptoms accompany them. During the physical examination, the doctor will check the mobility and any tenderness of the diaphragm.
Imaging studies
- Chest X-ray: It can reveal an abnormal position of the diaphragm, or abdominal organs that have slipped into the chest cavity
- CT scan: It provides a more detailed picture of the condition of the diaphragm and detects inflammation, abscesses or hernias
- Ultrasound: It is suitable for assessing diaphragmatic movement; it is a non-invasive, radiation-free method
Endoscopic examination – a gastroenterological approach
If symptoms of a diaphragmatic hernia are accompanied by digestive symptoms (reflux, dysphagia, heartburn), an upper endoscopy (gastroscopy) may also be indicated. This allows the extent of the hiatal hernia to be accurately determined, Cameron lesions to be detected, and any mucosal damage to be identified.
At Endomedix, the gastroscopy We carry out the procedure exclusively under deep anaesthesia using propofol – not under sedation. This means that the patient does not experience any discomfort during the examination and will have no recollection of the procedure. In our professional opinion, only this method ensures complete freedom from pain throughout the entire examination.
Respiratory function tests
If breathing difficulties are severe, a lung function test may also be carried out, which will reveal a reduction in respiratory capacity resulting from weakness or inflammation of the diaphragm.
Laboratory tests
A blood test can be used to determine whether there is an inflammatory process (elevated CRP, white blood cell count) or any abnormalities suggesting an infection. A stool test can also detect hidden (occult) bleeding, which may occur in cases of Cameron’s erosions associated with a hiatal hernia.
Treatment of diaphragmatic inflammation
The course of treatment depends on the underlying cause. Below, we review the most important options.
In the event of an infection
In the case of a bacterial infection, treatment with antibiotics is required; the doctor will prescribe these based on the type of pathogen. If the infection is viral in origin, antiviral medication may be prescribed, alongside rest and, if necessary, painkillers.
Gastroenterological treatment
If a hiatal hernia or reflux is also present, the treatment is supplemented by:
- Proton pump inhibitors (PPIs): They reduce stomach acid production and protect the mucous membrane
- Lifestyle changes: Eating smaller portions, avoiding lying down after meals, weight control
- Surgical correction: In the case of a large, symptomatic hiatal hernia, laparoscopic surgery (fundoplication) may be considered, whereby the oesophagus is repositioned below the diaphragm and the hernial opening is closed
Pain relief and relaxation
Complete rest is recommended whilst inflammation is present. Painkillers (non-steroidal anti-inflammatory drugs) may relieve chest and abdominal symptoms, but you should seek medical advice before taking them, particularly if you have digestive problems.
Dietary changes
During an episode of diaphragmatic inflammation, it is advisable to avoid:
- Heavy, fatty foods
- Foods that cause flatulence (pulses, cabbage)
- Acidic and spicy dishes
- Drinks containing carbon dioxide
Smaller, light, easily digestible meals are recommended, and it is advisable to allow at least two hours’ rest between your last meal and going to bed.

Frequently asked questions about the symptoms of diaphragmatic inflammation
What sort of pain does inflammation of the diaphragm cause?
Symptoms of diaphragmatic inflammation include a pressing, stabbing or burning pain felt in the centre of the chest or the upper abdomen. The pain usually worsens when breathing in, coughing or sneezing, and may radiate into the shoulder. It may ease at rest, but does not disappear completely.
Can the symptoms of diaphragmatic inflammation be confused with those of other conditions?
Yes, the symptoms of diaphragmatic inflammation can easily be mistaken for heart problems, pneumonia, cholecystitis or a stomach ulcer. That is why a thorough medical examination is important, which may include imaging tests and, in some cases, an endoscopy.
How long does it take for diaphragmatic inflammation to heal?
The duration of recovery varies depending on the cause. In the case of an infection, improvement is usually seen within a few weeks with appropriate treatment. If it is associated with a hiatal hernia or chronic reflux, longer-term treatment lasting several months may be necessary.
Is an endoscopic examination necessary in cases of diaphragmatic inflammation?
If symptoms of diaphragmatic muscle inflammation are accompanied by digestive complaints (reflux, heartburn, difficulty swallowing), a gastroenterologist may recommend gastroscopy, which can be used to identify diaphragmatic hernias and mucosal lesions. At Endomedix, this examination can be carried out exclusively under propofol-based anaesthesia, completely pain-free.
Which specialist should I see if I suspect I have diaphragmatic inflammation?
In cases where chest symptoms accompany digestive symptoms, an examination by a gastroenterologist is recommended. If breathing difficulties are the primary complaint, a pulmonologist may also be involved in the investigation. The At the Endomedix gastroenterology consultation The specialist will help determine what kind of investigation is required.
How can I prevent inflammation of the diaphragm?
It is not possible to prevent it entirely, but the following steps can reduce the risk: maintaining a healthy weight, eating smaller, lighter meals, avoiding smoking, taking regular exercise and ensuring that chronic reflux is properly managed. If you have already been diagnosed with a hiatal hernia, regular check-ups with a gastroenterologist are recommended.
