The diaphragm is the main muscle responsible for breathing, separating the chest cavity from the abdominal cavity. When the diaphragm is affected by any disease or problem, it can cause annoying symptoms such as difficulty breathing, chest pain, or digestive issues, significantly impacting our quality of life. article, we will discuss the most common diaphragm diseases, their causes, symptoms, and the latest treatment methods that can help you overcome the problem easily and safely. If you experience any of these symptoms, it's important to know the details so you can take the right treatment steps at the right time and maintain your health.
Diaphragm Diseases: Causes, Symptoms, and Treatment Methods
The diaphragm is the muscle that helps us breathe, and any problem affecting it can significantly impact our health. Let’s get to know the most common diaphragm diseases, their symptoms, and easy treatment methods:
Hiatal Hernia
This happens when part of the stomach pushes up through an opening in the diaphragm into the chest cavity.
Symptoms:
Persistent heartburn
Food or acid reflux into the esophagus
Chest or abdominal pain
Difficulty swallowing
Treatment:
Dietary adjustments (reduce fats, avoid eating right before sleeping)
Medications to reduce stomach acid
Surgery in severe cases
Diaphragmatic Paralysis
This occurs when the nerve supplying the diaphragm is damaged, causing the diaphragm to weaken or stop moving.
Causes:
Nerve injuries, especially to the phrenic nerve
Chest or neck surgeries
Neurological diseases
Symptoms:
Shortness of breath, especially when lying down
Quick fatigue with any exertion
Shoulder or chest pain
Treatment:
Special breathing exercises
Respiratory support devices
Surgery in some cases to restore diaphragm movement
Diaphragmatic Rupture
Usually caused by a severe trauma such as a car accident, resulting in a tear in the diaphragm allowing abdominal organs to enter the chest cavity.
Symptoms:
Severe difficulty breathing
Intense chest or abdominal pain
Abdominal organs visible on chest X-ray
Treatment:
Emergency surgical intervention to save the patient
Diaphragmatic Tumor
These tumors are rare and can be benign or malignant.
Symptoms:
Shortness of breath
Persistent chest pain
A lump that can be felt or seen on imaging
Treatment:
Depending on the tumor type, may require surgery, chemotherapy, or radiotherapy
Involuntary Contractions (Hiccups)
Sudden spasms of the diaphragm, usually temporary and harmless.
Causes:
Eating too fast or drinking carbonated beverages
Sudden temperature changes in the stomach
Stress or excessive laughter
In some chronic cases, neurological diseases
Treatment:
Usually resolve on their own
Try holding your breath, drinking water quickly, or breathing into a paper bag
If hiccups last more than 48 hours, consult a doctor
Congenital Diaphragmatic Hernia (CDH)
Occurs in newborns when part of the diaphragm does not form properly, allowing intestines to enter the chest cavity.
Symptoms in Infants:
Difficulty breathing right after birth
Small abdomen with a wide chest
Bluish skin color (cyanosis) due to low oxygen
Treatment:
Intensive care in the hospital
Immediate surgery to repair the diaphragm
Diaphragm Muscle Weakness Due to Chronic Diseases

Muscular dystrophy
Symptoms:
Shallow or weak breathing
Rapid fatigue with minimal effort
Need for respiratory support devices
Treatment:
Treating the underlying disease
Special breathing exercises to strengthen the muscle
Use of a ventilator in some cases
Diaphragmatic Inflammation
Inflammation of the diaphragm is rare but can occur due to bacterial or viral infections.
Symptoms:

Treatment:
Lifestyle modifications (healthy diet, elevating the head during sleep)
Medications to reduce acidity
Surgery in severe cases
Abnormal Diaphragm Movement (Paradoxical Diaphragm Movement)
In some cases, especially with partial paralysis of the diaphragm, the muscle moves in the opposite direction during breathing.
Symptoms:
Difficulty breathing when lying down
Constant fatigue
Chronic cough
Treatment:
Treating the underlying cause (neurological or surgical)
Regular breathing exercises
Surgery to stabilize the diaphragm in some cases
Diaphragm Injury After Surgery (Surgical Injury)
After major surgeries like heart, lung, or liver operations, the diaphragm may be affected due to injury or swelling.
Symptoms:
Sudden shortness of breath after surgery
Abdominal bloating

Diagnosing diaphragm problems involves several key steps and tests to find the real cause of symptoms and choose the right treatment.
The doctor will ask about symptoms like:
Shortness of breath
Chest or abdominal pain
Digestive issues
They’ll also ask about past surgeries, accidents, or neurological conditions.
A physical exam helps detect abnormal diaphragm movement or hernias.
A basic and common test that shows:
Abnormal elevation of the diaphragm
Herniated abdominal organs into the chest
More detailed than an X-ray. It helps detect:
Hernias
Diaphragm tears
Tumors or masses
Especially useful after trauma.
Used to evaluate tumors and nerve injuries affecting the diaphragm, like phrenic nerve issues.
A special test to check diaphragm movement during breathing.
It can detect diaphragm weakness or paralysis.
A non-invasive test that helps monitor diaphragm movement, especially useful in children and pregnant women.
If a nerve or muscle disorder is suspected, these tests measure the strength and function of the phrenic nerve and diaphragm muscle.
Measure lung capacity and identify breathing weakness caused by diaphragm problems.
If digestive symptoms like reflux or swallowing problems are present, an upper endoscopy may be done to check for hiatal hernia or stomach pressure.
Diaphragm disorders can lead to breathing problems and discomfort, but proper management can reduce symptoms and improve life quality.
If the disorder is due to:
Inflammation
Hernia
Tumor
Nerve or muscle weakness
The primary condition must be treated—whether through medication, surgery, or physical therapy.
If diaphragm weakness or paralysis is present, you might need:
Specialized breathing exercises (like deep breathing and strengthening respiratory muscles)
These devices can help improve diaphragm and lung function when there's significant weakness or paralysis.
For inflammatory or autoimmune diseases affecting the diaphragm, doctors may prescribe:
Anti-inflammatory drugs
Immunosuppressive medications
These help control inflammation and support muscle function.
Surgical intervention may be needed in cases of:
Large hiatal hernia
Diaphragmatic rupture
Tumors compressing the diaphragm
Congenital weakness that affects breathing
Surgery can repair damage and relieve symptoms.
Avoid strenuous physical activity if diaphragm weakness is present
Maintain a healthy weight to reduce abdominal and lung pressure
Quit smoking to protect lung health
Stress and anxiety can worsen breathing issues.
Relaxation exercises and breathing techniques can help reduce tension and improve respiratory function.
It's essential to have regular check-ups with your doctor to monitor your condition, assess treatment response, and make adjustments when necessary.
When you have a diaphragm issue, diet plays a key role in reducing pressure on the abdomen and making breathing easier.
Have smaller, more frequent meals instead of large ones.
Heavy meals can press on the diaphragm and worsen shortness of breath.
Opt for foods like:
Boiled vegetables
White rice
Grilled chicken
Avoid fatty and fried foods as they cause bloating and heaviness.
Such as:
Beans
Cabbage
Onions
Legumes
Gas increases abdominal pressure, making breathing more difficult.
These can trigger acid reflux, which increases pressure on the diaphragm.
Drink enough water to aid digestion and prevent constipation.
Avoid carbonated drinks—they cause bloating.
Sit in an upright position while eating to reduce pressure on the stomach and diaphragm.
Leave at least 2 hours between your last meal and bedtime to reduce reflux and abdominal pressure.
Consume plenty of:
Leafy greens
Fresh fruits
Whole grains
These support general health and muscle strength.
