Introduction

Diabetes is a chronic disease associated with high blood sugar levels. This is because the body is unable to use glucose effectively so therefore glucose levels are too high. The reason why there is too much glucose is because the pancreas may no longer produce insulin so therefore blood glucose cannot enter the cells to be used for energy (type 1) or either the pancreas does not make enough insulin or the body is unable to use insulin correctly (type 2). Diabetes . . . Type 1 This is the least common of the two types only about 5-10% of people suffering from diabetes suffer from type1. it is a long life condition in which the pancreas stops producing insulin. Without insulin the body is not able to use glucose for energy. To treat this disease people must inject themselves with insulin followed by a diet plan, exercise daily and testing your blood sugar levels several times a day. Type 2 Type 2 diabetes is the most common form of diabetes mellitus. About 90-95% percent of people who have diabetes have type 2 diabetes. People with type 2 diabetes produce insulin, but either do not make enough insulin or their bodies or do not use the insulin they make. ...read more.

These patients often tend to respond early to oral drugs to lower blood sugar but may need insulin at some point. Insulin is normally The symptoms . . . Type 1 . . . * Dry mouth * Always really thirsty * Needing the toilet a lot, especially at night * Weight loss * Weakness or fatigue * Blurry vision Type 2 . . . * Blurry vision * Cuts or sores that take a long time to heal * Itching skin infections * Always thirsty * Dry mouth * Needing the toilet a lot, especially at night * Leg pain Diabetes tests . . . There are three possible different tests for diabetes: Random glucose test is where glucose levels are taken at a random time (which could be as soon as you wake up in the morning or could be just before you go to bed) on two occasions. Any figure above 11.1mmol/l is a diagnosis of diabetes. Fasting glucose test is where the glucose level is measured after an overnight fast and on two different days. Above 7.0mmol/l is a diagnosis of diabetes. Finally a Glucose tolerance test can be carried out if the above tests are unclear. ...read more.

Conclusion

He discovered an essential hormone called insulin, named after the 'islands' of cells described by Langerhans. Throughout the 20th century, treatment of the disease has advanced significantly. Although prevention remains difficult, the life of an average diabetic is becoming both longer and easier all the time. But before all the discoveries it was very hard to cope with diabetes. Critique . . . The target audience my leaflet is for all people over 10 that are suffering with diabetes or the families that are living with a sufferer. If the leaflet was for anyone under the age of 10 I think they would find it confusing. I think all but one of the websites I used were trustworthy, I know that they were trustworthy because I crossed referenced them with at least one other website. The one website I thought wasn't 100% trustworthy was because I was unable to find another website to cross reference it with any other websites. In relation to this project I talked quite a lot to one of my mum's patients who are suffering from diabetes. Although I didn't use much information from her in my leaflet I wanted to have an understanding of what it is like to be suffering from a life threatening disease. ?? ?? ?? ??

Here's what a teacher thought of this essay

4 star(s)

This is a very good essay on diabetes 1 and 2. How they occur, the symptoms and treatments. Comments on how to expand the text and investigate other areas are given. Although stand alone it is still very good.
4 stars.

    Red blood cells can't carry both the CO and O2 so the carbon monoxide reduces the oxygen carrying capacity of the blood. The heart id more strained because it gets less oxygen. To compensate for less oxygen in the blood, the heart has to pump harder - the heart rate has to increase.

    When the substrate binds to the active site it forms a temporary bond and is know as an enzyme-substrate complex. The substrate reacts within the complex to form the products that then leaves the active site. This description of enzyme activity I know as the lock and key mechanism.

    Hormones can control heart rate when adrenaline is released from the adrenal medulla, flows in the blood and affects the SA node. The SA node is stimulated, works faster, increasing the heart rate. After leaving the heart, deoxygenated blood goes to the lungs to pick up oxygen and oxygenated blood

    Asthmatics exposed to high levels of cigarette smoke showed no positive reactions, "so tobacco smoke has never been proved to be an allergen"24. In 1970's doctors advised asthmatics to smoke to relieve their symptoms, as nicotine encourages the production of adrenaline, relaxing muscles. Nicotine inhibits serotonin production (related to histamine)
