What is a diaphragm?
The diaphragm is located between the upper abdomen and the chest. It is the muscle responsible for helping you breathe. As you inhale, your diaphragm contracts so your lungs can expand to let in oxygen; as you exhale, your diaphragm relaxes to let out carbon dioxide.
Some conditions and complications can cause diaphragm spasms, which can impede normal breathing and may be uncomfortable.
What causes a diaphragm spasm?
A diaphragm spasm can occur for a number of reasons and in varying severities. Sometimes the spasm is short-lived, particularly if it occurs as a result of a “sucker punch.”
Other causes are more involved and may have a number of additional symptoms associated with them.
Hiatal hernias are caused by weakened muscle tissues, which can be a result of an especially large hiatus (muscle space), injury, or persistent pressure on surrounding muscles.
Small hiatal hernias don’t usually cause problems, whereas large hiatal hernias can cause pain and difficulty breathing. Other symptoms of a hiatal hernia include:
- difficulty swallowing
- feeling overfull after meals
- passing black stool
- vomiting blood
Phrenic nerve irritation
The phrenic nerve controls the muscle of the diaphragm. It sends signals to your brain, which allows you to breathe without thinking. If your phrenic nerve becomes irritated or damaged, you may lose the ability to take automatic breaths. The condition can be caused by a spinal cord injury, physical trauma, or surgical complications. With phrenic nerve irritation, you might also experience:
- shortness of breath when lying down
- diaphragm paralysis
Your diaphragm can become temporarily paralyzed if you’ve “had the wind knocked out of you” from a direct hit to your abdomen. Right after the hit, you may have difficulty breathing, as your diaphragm might struggle to fully expand and contract. Other symptoms of temporary paralysis include:
- tightness in the chest
- pain in the chest
- pain in the stomach
Side stiches from exercise
Side stitches, or cramping in the ribcage, sometimes occur when you first begin exercise training or when that training becomes more intense. For some people, drinking juice or eating right before a workout can increase the possibility of side stiches.
If you overexert your diaphragm during exercise, it may start to spasm. When the spasm is chronic, it might be due to exercise-induced bronchospasm, and you may also experience:
- chest pain and tightness
- shortness of breath
- a dry cough
A diaphragm flutter is a rare condition that can be misdiagnosed as a spasm. A diaphragm flutter can also be caused by phrenic nerve irritation. Other symptoms associated with diaphragm flutter include:
- chest tightness
- difficulty breathing
- a feeling of pulses in the abdominal wall
How are diaphragm spasms treated?
Anecdotal evidence suggests that practicing controlled breathing can stop diaphragm spasms. To do this:
- Lie flat on your back on the floor or on a bed.
- Bend your knees slightly, placing one pillow beneath your knees and another under your head.
- Place one hand on your upper heart near your chest and the other hand on your upper abdomen just below the ribcage.
- Slowly breathe in through your nose. Feel your stomach moving against your hand.
- Tighten the muscles in your stomach, having your abdomen fall inward, and exhale through your mouth, with pursed lips.
To treat a hiatal hernia
This condition can be diagnosed through blood testing, esophageal X-ray, endoscopy, or manometry.
In some cases, surgery is necessary. It’s usually performed through a small incision in either your abdomen or chest wall. Lifestyle and home remedies include eating smaller meals, avoiding foods that can cause heartburn, avoiding alcohol, losing weight, and elevating the head of your bed.
To treat phrenic nerve irritation
This condition can be managed with a breathing pacemaker, which takes over the responsibility of sending messages to the diaphragm. The electrodes, which are placed around the nerve, are activated through the pacemaker and stimulate contractions of the diaphragm.
If one nerve is affected, you will receive one implant, and if both are affected, you will receive two.
Raise the arm corresponding to the side of the pain and place that hand on the back of your head. Hold it for 30 to 60 seconds to allow knots to loosen. You can even continue exercising while holding the stretch.
Additionally, you can apply pressure with your hand to the pain point and bend backward and forward slowly. To prevent side stitches before a workout, perform core stretches, including the one described above.
What is the outlook for a diaphragm spasm?
The outlook for diaphragm spasms varies widely depending on the cause. However, in most cases, either at-home treatments or medical treatments can cure the symptoms.
Sometimes the spasms are due to normal overexertion and can be relieved easily. In other cases, an underlying condition may need to be addressed, and once the condition is treated, the spasm is treated as well.
With new technologies and imaging equipment, doctors are more prepared than ever to determine the cause of a diaphragm spasm and come up with a positive treatment plan.
