Hypermobility spectrum disorder does not include people with asymptomatic hypermobility or people with double-jointedness but no other symptoms. Hypermobile Ehlers–Danlos syndrome and hypermobility spectrum disorders may be equally severe. [5] [6] HSD is further classified into different subtypes, which include: [6]
Hypermobility has been associated with myalgic encephalomyelitis (chronic fatigue syndrome) and fibromyalgia. Hypermobility causes physical trauma (in the form of joint dislocations, joint subluxations, joint instability, sprains, etc.). These conditions often, in turn, cause physical and/or emotional trauma and are possible triggers for ...
As blood is pumped through the body, the valves within the veins prevent the blood from flowing backwards. After extensive, prolonged standing, these valves can become weak and eventually fail. When this happens, blood is no longer being prevented from flowing backward. Gravity will pull the blood back into an individual's legs, ankles and feet.
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
At set pressure the valve snaps to full lift. This can be quite violent on large pipes with significant pressure. The pressure has to drop below the set pressure in order for the piston to reseat (see blowdown in relief valve article). Modulating The pilot is designed to open gradually, so that less of the system fluid is lost during each ...
The blood pressure reading is recorded as two numbers, systolic and diastolic. The systolic blood pressure represents the amount of pressure the blood is applying against artery walls during heartbeats whereas the diastolic blood pressure shows while the heart is resting between beats. [citation needed]
High diastolic blood pressure measured while standing in a person who stood up shortly after waking up. When it affects an individual's ability to remain upright, orthostatic hypertension is considered as a form of orthostatic intolerance. The body's inability to regulate blood pressure can be a type of dysautonomia.
Hypermobility may refer to: Hypermobility (joints), joints that stretch further than normal Hypermobility spectrum disorder, a heritable connective tissue disorder;
