High Aperture Persistent Single Sided

High standing (hypertonicity) of the diaphragm is a condition in which the diaphragm muscle is under excessive tension and cannot function normally. This is usually accompanied by chest and abdominal pain, difficulty breathing, fatigue and headache. Constant high standing can lead to disruption of the cardiovascular system and other diseases.

Unilateral high standing is the most common type of this pathology. Most often it is observed in women associated with pregnancy, the postpartum period, hormonal changes, stress, and heavy physical activity. Pathologies of the nervous system, infections, dysfunction of the thyroid gland and other diseases can also lead to unilateral hypertonicity.

The reasons for this condition may be different, but the main one is disruption of the nervous system. In this case, the nerve impulse contains an excessive excitatory signal. In addition, the action of the inhibitory center in the diencephalon, which controls the functioning of the diaphragm, may also be impaired.

The high position of one part of the diaphragm can be transmitted to another part through the general nervous system. An increase in the tone of one part of the diaphragm provokes an increase in tonic reflexes in neighboring areas of the body, leading to hypertonicity of the diaphragm on both sides.
