You could include examples of what happens when homeostatic mechanisms do not function efficiently and the resulting symptoms. E.g. Irregular heartbeat or inability to control blood sugars.
Irregular heartbeat.
I will be firstly talking about an irregular heartbeat.
An irregular heartbeat is an arrhythmia also called dysrhythmia. Heart rates can also be irregular. A normal heart rate is 50 to 100 beats per minute. Arrhythmias and abnormal heart rates don't necessarily occur together. Arrhythmias can occur with a normal heart rate, or with heart rates that are slow called bradyarrhythmias - less than 50 beats per minute. Arrhythmias can also occur with rapid heart rates called tachyarrhythmias - faster than 100 beats per minute. …show more content…
An arrhythmia can be silent and not cause any symptoms. A doctor can detect an irregular heartbeat during a physical examination by taking your pulse or through an electrocardiogram. When symptoms of an arrhythmia occur, they may include: Palpitations, Pounding in your chest, Dizziness or feeling light-headed, Fainting, Shortness of breath, Chest discomfort and Weakness or fatigue.
Treatment depends on the type and seriousness of your arrhythmia. According to med net ‘’some people with arrhythmias require no treatment. For others, treatments can include medication, making lifestyle changes, and undergoing surgical procedures’’.
A variety of drugs are available to treat arrhythmias. These include:
Antiarrhythmic drugs; these drugs control heart rate and include beta-blockers. Anticoagulant or antiplatelet therapy; these drugs reduce the risk of blood clots and stroke, these include warfarin or aspirin. Another blood thinner called Pradaxa (dabigatran) was approved in 2010 to prevent stroke in people with atrial fibrillation. Because everyone is different, it may take trials of several medications and doses to find the one that works best for …show more content…
Insulin regulates the level of glucose in your blood. Glucose is a simple form of sugar found in foods and sugary drinks. It's absorbed by your body as a natural part of digestion and is carried around your body in your blood. According to Bupa health ‘’when glucose reaches your body tissues, such as muscle cells, it's absorbed and converted into energy’’. Insulin is secreted into your blood by your pancreas, which is a gland located behind your stomach. A shortage of insulin causes glucose to build up in your blood.
People with this type of diabetes have to inject regular insulin to keep their sugar levels under control which means they have to be more careful when exercising as the sugar levels will fluctuate. They also have to make sure they take the right dose at the right times every day because if they don’t they could go into a hypoglycaemia coma and if they take the insulin but don’t eat then they could go into a Hyperglycaemia coma.
The brain and nervous system use only glucose, while most other cells can also utilise fat for
