ACUTE EFFECTS    

Main Menu

 

Millions of people suffer from the effects of hypocapnia, without even realising it, when they go to work, face life challenges, and communicate with others.  These effects can be dramatic, disturbing, disruptive, even terrifying as in the case of panic attack.  They are usually misinterpreted by everyone, including the person overbreathing, friends, family, colleagues, counsellors, and healthcare practitioners.  The effects are usually identified as “unexplained,” or they are attributed to other “causes,” usually ones consistent with practitioner bias and professional background.

 

Based on surveys regarding ambulance calls, 60 percent of the ambulance runs in the larger USA cities may be a direct consequence of symptoms precipitated by overbreathing!  Some of the acute (immediate) symptoms triggered by overbreathing include:

 

RESPIRATION: shortness of breath, breathlessness, feelings of suffocation

CHEST: tightness, pressure, and pain

SKIN: sweaty, cold, tingling, and numbness

HEART: palpitations, irregularities, increased rate

EMOTION: anxiety, anger, panic, apprehension, worry, outburst, crying

STRESS: tenseness, fatigue, weakness, headache, hypertension

HEAD: dizziness, loss of balance, fainting, black-out, confusion, disorientation

SENSES: blurred vision, dry mouth, sound seems distant, reduced pain threshold

SELF: traumatic memories, low self-esteem, personality shifts

COGNITION: attention deficit, loss of focus, inability to think, poor memory

CONSCIOUSNESS: feelings of “other worldliness,” sense of disconnectedness, hallucinations

PERIPHERAL CHANGES: trembling, twitching, and shivering

MUSCLES: tetany, spasm, weakness, fatigue, and pain

ABDOMEN: nausea, cramping, and bloatedness.

 

Acute effects of hypocapnia, depending on the person, can trigger symptoms of all kinds, including virtually all of the symptoms identified with the “effects of stress.”  An example is increased likelihood of bronchial constriction, increased airway resistance, and reduced lung compliance, effects which made lead to laboured breathing (difficulty in “getting your breath”) and contribute substantially, both physically and psychologically (e.g., fear of not getting your breath), to the likelihood of a breathing-struggle episode, even an asthma attack.  Other examples include muscle constriction in (1) the gut, leading to increased likelihood of spasm, pain, and nausea, and (2) the vascular system, leading to dramatically reduced oxygen and glucose supply to the brain, coronary constriction in the heart, vascular resistance, and possible vasospasm and high blood pressure.
