Mytonia dystrophy will not cause muscle spasms in the diaphragm.Myotonic dystrophy patients commonly have weakness of the diaphragm, abdominal muscle, and intercostal muscles (between the ribs) causing poor breathing force and resulting in low blood oxygen levels. Severe respiratory issues may require emergency medical attention. Sleep apnea- Individuals with decreased muscle tone and structural features that narrow airways are at high risk for obstructive sleep apnea. Individuals with apnea repeatedly pause their breathing while they sleep, lowering the levels of oxygen. In mild cases, the resulting low levels of oxygen and disrupted sleep can lead to excessive fatigue and morning headaches; in more serious cases, increased blood pressure, cardiac arrhythmia and fatal heart attacks may occur.
