Lecture 3 - Medical Conditions Flashcards
what is type 1 diabetes?
- aka juvenile diabetes
- pancreas fails to produce enough endogenous insulin
- can’t get sugar out of blood and into cells
- filtered out by kidneys
- leads to dependence on exogenous insulin
what is type 2 diabetes?
- inadequate insulin produced by the pancreas
- defect in signaling to glut-4 (resistance at the cellular level)
what is hypoglycemia? and what are the signs?
- minimal sugar in the bloodstream
- caused by too much insulin, not eating, or excessive exercise
- decreased nutrients in the brain
- hunger
- double vision
- insulin shock/reaction
what is hyperglycemia? and what are the common signs?
- sugar in the blood stream, can’t get into the tissue
- cells starving
- body starts converting fat
- acidosis
- breath has a fruity smell
- frequent urination
- thirst
- possible coma
what are the common signs of hyper and hypoglycemia?
- altered level of consciousness (dizzy, drowsy, confused)
- rapid breathing
- rapid pulse
- feeling ill
how do you treat hyper/hypoglycemia?
- ask if they have eaten or taken insulin
- look for medical bracelet
- give sugar (glucose) –> juice, hard candy, glucose tablets, non-diet soft drinks
- monitor for 5 minutes
- improvement if hypo
- no improvement if hyper –> refer to emergency medical care
what is epilepsy?
- reoccurrence of unprovoked seizures
- results from a discharge of electrical activity in the brain
- > 2 seizures to be termed epilepsy
what are the three types of seizures?
- focal onset
- generalized onset
- unknown onset
what are focal onset seizures?
- aware or impaired awareness
- motor or non-motor
- focal to bilateral
- tonic-clonic
what are generalized onset seizures?
- impaired awareness
- motor (tonic-clonic or other-motor)
- non-motor (absence)
what are the types of unknown onset seizures?
- motor (tonic-clonic or other-motor)
- non-motor (absence)
what are the characteristics of a focal seizure?
- occurs in one part of the brain and activates only a small number of neurons
- are aware they have had it and potentially know before it happens
- aware = usually consisting of brief sensory, motor, or memory-related symptoms
- impaired awareness = usually associated with behavioural arrest, staring, blinking, and automatisms, lasting minutes with postictal amnesia
- can be motor or nonmotor (classified by the first prominent sign or symptoms)
what are the characteristics of a generalized seizure?
- bilateral discharge involving the entire cortex. impaired awareness
- generalized motor = motor, athlete falls to the ground, goes through tonic phase of stiffness, followed by clonic phase of twitches (tonic-clonic seizure)
- generalized non-motor = sudden interruption of activity followed by a blank stare, eye fluttering and head nodding (absence)
what are the characteristics of an unknown onset seizure?
- motor = athletes falls to ground, goes through a tonic phase of stiffness, followed by clonic phase of twitches
- non-motor = sudden interruption of activity followed by a blank stare, may or may not realize it occurred
what is the management for seizures? (during and after)
- protect their head
- remove closeby objects
- do not restrain the athlete
- do not place object in their mouth
- position on side in recovery position ASAP
- time seizure (activate EAP if longer than 5 minutes or the first time)
- assess for injury (contusions, dislocations)
what are common seizure triggers for epileptics?
- fatigue
- exertion
- stress
- intense activity
- structural lesions (mechanical damage)
what are the benefits of exercise for epileptics?
- enhances alertness and focus –> increases seizure threshold (less often and less severe)
- normalizes EEG
- should avoid sports where the environment cannot be controlled (rock climbing, scuba, skiing, motor racing, horseback riding?)
- swimming should only be done with a buddy
what is asthma?
- a chronic inflammatory disorder of the airways
- excess mucus production
- bronchial smooth muscle constriction
- airway narrowing
- expiratory flow rate is reduced
- muscle efficiency is eventually lost (diaphragm and intercostal muscles compensate)
- leads to respiratory muscle fatigue and physical distress (may result in death)
what are the signs and symptoms of asthma?
- recurrent episodes of wheezing
- breathlessness
- chest tightness (or chest pain in children)
- coughing (dry) –> at night/early morning, and after exercise especially in cold/dry environments
what is exercise-induced bronchospasm?
- temporary narrowing of the airways, induced by exercise (patient has no symptoms)
- not the same as exercise-induced asthma
what is happening to the lungs during EIB?
- symptoms peak 8-12 minutes after exercise
- exercise triggers bronchoconstriction
- dehydration of the lung’s airways
- inhaled air is dry and cool
- air warmed/humidified in the lungs = drying out
- after exercise the cells rehydrate (hyperemia) –> this triggers bronchoconstriction
- degree is dependent on: exercise intensity, temperature and humidity
what is needed to diagnose EIB?
- symptoms
- obstructed airways resulting in 10-15% decreased FEV (forced expiratory volume)
*both have to be associated with exercise
how do you test for EIB?
- athlete works for 6-8 minutes at 80% max
- test with cold air
- check FEV
How do you manage/cope with EIB?
- educate
- avoid irritants (if possible)
- use bronchodilators (as prescribed)
- position for ideal breathing (if it does occur) and breathe slowly
