Health implications of diabetes type I Physical Activity What is physicalactivity? Why do we need physical activity in our lives? Physical Activity andDiabetes (Epidemiology)For our seminar topic “physical activity and disease” we chosediabetes as the focus of our research. Since diabetes is such a complex diseasewith many different forms, we decided to focus on diabetes type I. This is knownas insulin-dependent diabetes mellitus (IDDM). This type of diabetes includespeople who are dependant on injections of insulin on a daily basis in order tosatisfy the bodies insulin needs, they cannot survive without these injections.
OVERVIEW OF DIABETES TYPE I What is diabetes type I? In order to understand thedisease we firstly need to know about insulin. Insulin is a hormone. The role ofinsulin is to convert the food we eat into various useful substances, discardingeverything that is wasteful. It is the job of insulin to see that the usefulsubstances are put to best use for our well-being. The useful substances areused for building cells, are made ready for immediate expenditure as energy andalso stored for later energy expenditure.
The cause of diabetes is an absoluteor lack of the hormone insulin. As a result of this lack of insulin theprocesses that involve converting the foods we eat into various usefulsubstances does not occur. Insulin comes from the beta cells which are locatedin the pancreas. In the case of diabetes type I almost all of the beta cellshave been destroyed. Therefore daily injections of insulin become essential tolife. Health implications of diabetes type I One of the products that is ofvital importance in our bodies is glucose, a simple carbohydrate sugar which isneeded by virtually every part of our body as fuel to function.
Insulin controlsthe amount of glucose distributed to vital organs and also the muscles. Indiabetics due to the lack of insulin and therefore the control of glucose givento different body parts they face death if they don’t inject themselves withinsulin daily. Since strict monitoring of diabetes is needed for the control ofthe disease, little room is left for carelessness. As a result diabetic patientsare susceptible to many other diseases and serious conditions if a proper courseof treatment is not followed.
Other diseases a diabetic is open to:Cardiovascular disease, stroke, Peripheral artery disease, gangrene, kidneydisease, blindness, hypertension, nerve damage, impotence etc. Basically thereis an increased incident of infection in diabetic sufferers. Therefore specialcare needs to be taken to decrease the chances of getting these other seriousdiseases. PHYSICAL ACTIVITY What is physical activity? (Bouchard 1988) Statesthat physical activity is any bodily movement produced by skeletal musclesresulting in energy expenditure.
Therefore this includes sports and leisureactivities of all forms. Why do we need physical activity in our lives? Physicalactivity and exercise helps tune the ;human machine;, our bodies. Imagine a car constantly driven only to stop for fuel. It would be a client forall sorts of damage, rusting, oil leaking, dehydration and the chances are mostlikely it would die in the middle of the road not long after.
This is what thebody would be like if we didn’t exercise at all. We would be and as a result oftodays lifestyle many of us are, the perfect target to all kinds of diseases andinfections. For those of us who are carrier of some disease or illness we arestill encouraged to exercise by our physicians if we have the strength to. Thisis to help make our organs, muscles, bones and arteries more efficient andbetter equipped to fight against the disease or illness.
This is our way ofcounter attacking. And if we are still healthy then we reduce the chances ofgetting an illness or a disease. PHYSICAL ACTIVITY AND DIABETES (EPIDEMIOLOGY)Recently insulin injections have become available to dependant patients. Howeverin the pre-insulin era physical exercise was one of the few therapies availableto physicians in combating diabetes.
For an IDDM carrier to benefit fromexercise they need to be well aware of their body and the consequences ofexercising. If an IDDM carrier has no real control over their situation and justexercise without considering their diet, time of insulin intake, type ofexercise, duration of the exercise and the intensity, then the results can bevery hazardous to the patient.
