Quick answer: A diaphragmatic spasm is an involuntary, spasmodic contraction of the diaphragm, which most commonly manifests as hiccups, or as chest or abdominal pain. Short-lived episodes are generally harmless, but in the case of persistent or recurrent diaphragmatic spasms, a gastroenterological examination is recommended to determine the cause.
Diaphragmatic spasms are one of the most common, yet often misunderstood, physical phenomena. Almost everyone has experienced a brief, uncomfortably intense hiccup, a tightening sensation in the chest or sudden difficulty breathing after a meal – these are all typical manifestations of diaphragmatic spasms. In most cases, they subside within a few minutes and do not require any treatment.
However, there may be more serious underlying causes behind diaphragmatic spasms. Reflux disease, a hiatal hernia or neurological problems can all trigger them, and in these cases, recurrent spasms serve as warning signs. This is particularly important for those who have long suffered from digestive complaints, heartburn or irregular stomach function.
This article explains in detail what a diaphragmatic spasm is, what can trigger it, how to relieve it at home, and when you should seek specialist medical advice. If you have persistent or recurring symptoms, do not ignore them – a timely consultation with a gastroenterologist can be of great help.
What is the diaphragm, and what happens when it goes into spasm?
The role of the diaphragm in the body
The diaphragm is a dome-shaped muscle that separates the abdominal cavity from the thoracic cavity. During breathing, it contracts and relaxes rhythmically: it draws downwards during inhalation to make room for the lungs to expand, and rises back up during exhalation. In addition, the diaphragm plays an active role in the functioning of the digestive system – particularly the right lobe of the diaphragm, which, by contracting, increases the pressure at the junction of the oesophagus and stomach (oesophagogastric junction), thereby performing a kind of external sphincter function.
What does a diaphragmatic spasm mean?
In the case of a diaphragmatic spasm, the muscle contracts involuntarily and suddenly. This spasmodic contraction is accompanied by a characteristic sensation: air enters the lungs, but the vocal cords suddenly close, resulting in the well-known hiccup. A diaphragmatic spasm is therefore nothing other than the mechanism of the hiccup itself – a brief, repetitive, reflex-like muscle contraction accompanied by a characteristic sound and an unpleasant sensation.
It may occur as a single episode, or it may come on suddenly, in which case several contractions follow one another in quick succession. In most cases, it subsides of its own accord within a few minutes.
What are the most common causes of diaphragmatic spasms?
Everyday, harmless triggers
In most cases, diaphragmatic spasms are caused by completely harmless, everyday factors:
- Eating or drinking too quickly
- Consumption of carbonated drinks
- Sudden changes in temperature (e.g. eating cold food after hot food)
- Coughing, sneezing, laughing
- Strong emotional response (excitement, fear, joy)
- Swallowing air whilst eating
These episodes usually resolve themselves within a few minutes and do not require medical intervention.
Gastroenterological causes: reflux and hiatal hernia
In the case of persistent or recurrent diaphragmatic spasms, it is worth investigating possible causes relating to the digestive system. Gastro-oesophageal reflux disease (GERD) is one of the most common contributing factors: the backflow of stomach acid into the oesophagus, bloating caused by a full stomach and increased pressure can easily irritate the diaphragm, leading to repeated spasms.
A hiatal hernia is also an important gastroenterological condition. In this condition, part of the stomach is pushed partially into the chest cavity through the opening in the diaphragm. This anatomical abnormality disrupts the normal functioning of the diaphragm and increases the risk of diaphragmatic spasms, particularly after eating or when lying down.
Causes relating to the nervous system and other internal organs
Irritation of the phrenic nerve (which innervates the diaphragm) or the vagus nerve may also cause spasms. This may be caused by:
- Tonsillitis, throat conditions
- Neck or chest injuries, operations
- Kidney failure (the accumulated toxins irritate the nerve pathways)
- Neurological disorders, rarely brain lesions
In cases of chronic hiccups (lasting longer than 48 hours), the cause must always be clearly identified.
When is it essential to see a doctor for a diaphragmatic spasm?
Warning signs that must not be ignored
Most episodes of diaphragmatic spasm resolve within a few minutes. However, you should definitely consult a specialist in the following cases:
- A spasm (hiccups) For longer than 12 hours lasts
- It hasn't stopped even after 48 hours (chronic hiccups)
- In addition to the symptoms fever, chest pain, dizziness or shortness of breath is associated with
- He comes back regularly, especially after a meal
- Weight loss, difficulty swallowing or night-time symptoms may also occur
In such cases, the symptoms may be caused by gastro-oesophageal reflux disease, a hiatal hernia, neurological involvement or – rarely – a more serious internal disease, which can only be accurately identified through a specialist examination.
How can you relieve a diaphragmatic spasm?
Methods you can try at home
In the case of a brief, occasional diaphragm spasm, there are a number of home remedies that can help to relieve the symptoms quickly:
- Breath-holding – holding your breath for a few seconds raises the carbon dioxide level in your blood, which relaxes the diaphragm
- Cold water drunk slowly – helps to disrupt the rhythm of the spasm
- Pulling the knees up to the chest – when performed in a seated position, it reduces the pressure on the diaphragm
- Licking a teaspoon of sugar – Stimulation of the pharynx may inhibit the hiccup reflex
- Slow, deep abdominal breathing – consciously relaxes the diaphragm
Medical treatment options for persistent symptoms
If diaphragmatic spasms are recurrent, the doctor will first attempt to identify the underlying condition. In the case of reflux, acid-reducing medication (proton pump inhibitors) and lifestyle changes are recommended. In the case of a hiatal hernia, medication may be prescribed, whilst in more severe cases, laparoscopic surgery may be considered. In cases of nervous system irritation, the course of treatment is determined by the underlying cause.
How is Endomedix involved in the investigation of diaphragmatic spasms?
The investigation of persistent or recurrent diaphragmatic spasms falls within the remit of gastroenterology, as the most common causes – reflux disease and hiatal hernia – are both linked to the functioning of the digestive system. This is precisely where the Endomedix, Hungary’s leading private network of gastroenterology clinics.
Endomedix has been providing high-quality gastroenterological care for over 18 years, and currently 10 cities in Hungary – including in Budapest, Debrecen, Győr, Miskolc and Veszprém – welcomes patients. Within the network More than 100 experienced specialists and they employ the same number of specialist staff. To date, they have treated more than 250,000 satisfied patients and carried out over 100,000 successful endoscopic examinations.
Endomedix’s specialists assist not only with the examination, but also with interpreting the diagnosis and drawing up a personalised treatment plan. If there is a suspicion of a hiatal hernia or reflux disease, a gastroscopy may also be carried out – which is performed at Endomedix are performed exclusively under general anaesthesia (deep sedation with propofol), rather than the more outdated anaesthetic. This ensures that the examination is pain-free throughout and leaves no unpleasant memories afterwards.
When is a gastroenterology consultation recommended in the event of diaphragmatic spasms?
If diaphragmatic spasms recur regularly, last for more than 12 hours, or are accompanied by other digestive symptoms (heartburn, bloating, acid burps, abdominal pain), in order to identify the cause consultation with a specialist in gastroenterology the most effective first step.
During a gastroenterology consultation at Endomedix, the specialist will assess your symptoms in detail, determine which tests are required, and provide personalised advice on treatment.

Frequently asked questions about diaphragmatic spasms
What is the most common symptom of a diaphragmatic spasm?
The most typical symptom of a diaphragmatic spasm is hiccups – a sudden, involuntary contraction of the diaphragm, accompanied by a characteristic sound and an unpleasant sensation. In some cases, a feeling of tightness in the chest or abdomen may occur, and, rarely, breathing difficulties may also develop.
How long can a diaphragm spasm last, and when is it considered abnormal?
In most cases, a diaphragmatic spasm subsides within a few minutes. If it lasts for more than 12 hours, you should see a doctor. Hiccups lasting longer than 48 hours – known as chronic hiccups – always require a thorough examination, as there is almost certainly an underlying medical condition.
Is diaphragmatic spasm linked to gastro-oesophageal reflux disease?
Yes, there is a close link between them. One of the characteristic symptoms of gastro-oesophageal reflux disease (GERD) is recurrent diaphragmatic spasms, as the backflow of stomach acid and increased gastric pressure directly irritate the diaphragm and the vagus nerve. Treating reflux usually also resolves the recurrent spasms.
What should I do if I regularly get diaphragm spasms after meals?
If you experience regular diaphragmatic spasms after meals, it is worth considering the possibility of reflux disease or a hiatal hernia. It is advisable to avoid eating too quickly, foods that cause bloating and carbonated drinks. If the symptoms recur, a consultation with a gastroenterologist is necessary to identify the exact cause.
What kind of test can be used to identify the cause of a diaphragmatic spasm?
During a gastroenterology consultation, the specialist will assess your symptoms and decide which tests are necessary. If reflux or a hiatal hernia is suspected, an endoscopy may be considered. At Endomedix, the procedure is carried out exclusively under general anaesthesia, so it is completely painless.
Can diaphragmatic spasms occur in children as well?
Yes, diaphragmatic spasms can occur in anyone, regardless of age. In children, they are usually caused by the same harmless factors as in adults. If the spasms are persistent or particularly severe, it is advisable to consult a doctor, even in children.
