Exercise as it relates to Disease/Combating Dyslipidaemia: Exercise vs Pharmaceutical intervention

Cholesterol and triglycerides are widely grouped together as Lipids or fats and are an important component to the normal functioning of the body. When blood lipid (fats) concentrations become either too high or too low, this condition is described as Dyslipidaemia. The most common forms of Dyslipidaemia are high levels of Low density Lipoprotein (LDL) or “bad” cholesterol, Low levels of High density Lipoproteins (HDL) or “good” cholesterol and high levels of triglycerides. According to the 2011-2012 Australian health survey, 63.2% of the Australian population over the age of 18 have some sort of lipid disorder, Furthermore it is estimated that 5.6 million Australian adults have unmanaged high blood cholesterol and of these adults only 1 in 10 are consciously aware of this fact:. === Causes of Dyslipidaemia === Dyslipidaemia is a condition that is caused by many different factors. In developed countries the most prevalent cause of Dyslipidaemia is the combination of sedentary lifestyle and excessive consumption of fatty foods. Genetic abnormalities (inherited), certain forms of medication and the presence of other diseases can also induce abnormal lipid concentrations in the blood, other lifestyle factors like obesity, smoking, and alcoholism are also common contributors.

The target Blood lipid concentrations for health are: 
 * Triglycerides - Between 10-150 Mg/dL
 * Total cholesterol - Less than 200 Mg/dL
 * HDL - Between 40-60 Mg/dL
 * LDL - Between 10-150 Mg/dL

Blood lipid concentrations above or below these norms, if not managed can lead to developing serious health issues (diabetes, atherosclerosis, strokes, heart disease etc).

Treatment/Intervention
There are two main methods of combating dyslipidaemia, one being exercise and lifestyle, the other being the use of pharmaceutical drugs. The aim of these methods is to return the blood lipid concentration back to the recommended ranges. === Pharmaceutical === Drug intervention in combating dyslipidaemia provides patients with a proven and efficient method of lowering their blood lipid concentrations, drug therapy although expensive has been proven to lower blood LDL levels by about 30-40%. There are many different drugs on the market today for treating dyslipidaemia, below is a summary of the main classes of drugs currently in use: The drugs above are usually combined to greater affect, caution need to be taken when administrating these drugs to children, pregnant and (or) nursing mothers.

=== Exercise/Lifestyle === Exercise in combination with lifestyle and diet intervention is considered the primary method of combating dyslipidaemia, for many individuals this approach has proven to be safer and much more effective in lowering blood cholesterol concentrations. Exercise and lifestyle modification target the following: Exercise offers many positive benefits to lowering blood lipid concentrations, however it also poses many potential risks, in particularly for patients whose blood lipid concentrations are > 250 (Mg/dL). In this case exercise may in fact be detrimental as it can induce potentially fatal conditions such as strokes or heart attacks.
 * Lowering total body fat (↓ triglyceride levels).
 * Increase LDL utilization by muscles (↓ LDL levels).
 * Increase HDL (good cholesterol) activity and decrease consumption of fats, sugars and syrups.

== Recommendations/ further readings == Lifestyle therapies that combine diet and exercise interventions are cheaper, safer and more effective in combating dyslipidaemia, for these reasons it is often the preferred method of intervention.

Diet- Aims is to reduce cholesterol levels, this can be done by: Exercise- Aims to burn excess triglyceride (loose weight), this is done by: Below are some further readings:
 * reducing consumption of animal fat, replace saturated fat with mono or poly saturated fat, reduce overall energy intake, increase the consumption of fruits, veges, plant Sterols and Stenols etc.
 * A high amount of vigorous intensity (65%-80% of vo2 max) exercise on a regular basis (equivalent to 32 km of jogging weekly), cutting out sedentary habits, method like walking to the shops, work, or school and general ↑ in physical activity. Dyslipidaemia patients should always consult a health care professional before commencing an exercise program.
