diabetes

• but in some body conditions, the pancreas cannot make enough insulin to keep their blood glucose level constant - it raises to very high concentrations. This is a disease called diabetes.
• symptoms of diabetes:

  1. Someone suffering from diabetes may have such high concentration of glucose in the blood that it is excreted in their urine, this can be tested by a chemical test on urine. 

  2. constant thirst. This is because the high blood concentration stimulates receptors in the hypothalamus of the brain. These ‘thirst centers’ are stimulated, so that by drinking, the person will dilute their blood.
• Diabetes is dangerous because:if it is untreated, the sufferer loses weight and becomes weak and eventually falls into a coma and dies
•  two ways a person with diabetes can monitor their blood sugar level: 

  1. People with diabetes can check their blood glucose using a special sensor. They prick their finger and place a drop of blood on the test strip. The strip is then put into the sensor, which gives them an accurate reading of how much glucose is in their blood. 
  2. checking the presence of glucose in their urine by a chemical test on the urine.
• two ways that a person with diabetes can help to control their blood glucose level:1. by eating a good diet and limit the amount of carbohydrate they eat

  2. by doing regular exercise.
