Conditions that affect the nerves that control the diaphragm can result in weakness or complete paralysis of the muscle. Nerve injury-induced diaphragmatic weakness can result in shortness of breath, especially when lying down. Management may require medication, surgery, rehabilitation, or support with mechanically assisted breathing. Lung disease, especially COPD , can cause weakness of the diaphragm. This happens through a progressive process that involves a number of contributing factors.

COPD results in hyperinflated lungs that physically push on the diaphragm. The whole muscle becomes flattened and its mobility declines. Over time, the cells of the diaphragm are altered due to excessive strain, causing them to lose the ability to function with maximal strength. Chronic oxygen deprivation due to COPD also damages these cells. The result of COPD-induced diaphragmatic weakness is worsening shortness of breath.

Treatment of COPD can help slow down the damage to the diaphragm. If oxygen levels are affected, treatment with supplemental oxygen may be necessary. Tumors can spread to the diaphragm or may take up space in the chest or abdominal cavity, placing physical pressure on the diaphragm and interfering with its ability to function.

For example, mesothelioma —a cancer of the pleura lining of the lungs —can spread to the diaphragm. Lung cancer , lymphoma , and stomach cancer are other types of cancer that may affect the diaphragm. The symptoms can be gradual or abrupt, and may include shortness of breath, pain with breathing, or loss of consciousness.

Evaluation of the diaphragm can include a variety of tests tailored to the suspected medical problem. Imaging tests such as chest or abdominal computerized tomography CT , magnetic resonance imaging MRI , or ultrasound may identify anatomical variations or tumors. A hiatal hernia diagnosis may include tests like an upper endoscopy or a barium swallow , which evaluate the structure of the gastrointestinal system.

And COPD-associated diaphragmatic problems may be assessed with breathing tests like spirometry or pulmonary function tests.

Larger hiatal hernias sometimes require surgical repair, but other cases are usually manageable with over-the-counter antacid medication. Proton pump inhibitors can also help to reduce acid production and heal any damage to the esophagus. A diaphragmatic hernia happens when at least one abdominal organ bulges into the chest through an opening in the diaphragm. Injuries from an accident or surgery can also cause a diaphragmatic hernia.

Symptoms can vary depending on the size of the hernia, the cause, and the organs involved. They may include:. Both an ADH and CDH require immediate surgery to remove the abdominal organs from the chest cavity and repair the diaphragm. A diaphragmatic cramp or spasm can cause chest pain and shortness of breath that can be mistaken for a heart attack. Some people also experience sweating and anxiety during a diaphragm spasm.

This inflates the lungs, causing the diaphragm to tighten. This can also cause a cramping sensation in the chest. Vigorous exercise can cause the diaphragm to spasm, which often results in what people call a side stitch. During an episode, someone might feel the fluttering as a pulsing sensation in the abdominal wall.

This damage can cause dysfunction or paralysis of the diaphragm. When it does, possible symptoms include:. A condition affecting the diaphragm can cause symptoms similar to those of a heart attack. Seek emergency treatment if you experience chest pain or pressure that extends to your jaw, neck, arms, or back. Like any muscle, you can also strengthen your diaphragm with special exercises. Diaphragmatic breathing or abdominal breathing is the best way to do this.

It involves inhaling deeply and slowly through the nose so that your lungs fill with air as your belly expands. Along with strengthening your diaphragm, diaphragmatic breathing can also reduce stress and lower blood pressure.
