Medical TreatmentCoeliac condition can usually becontrolled by diet and no medicaltreatment is necessary 6. Diabetes Mellitus Diabetes Mellitus is characterised byraised glucose levels in the blood due toinsulin deficiency or inability of insulin tofunction. Insulin is a hormone in the pancreas,which controls the amount of glucose inthe blood. 7. If insulin is deficient or ineffective largeamounts of glucose remain in the bloodstream instead of being converted intoenergy. The results of these reactions, toxins areproduced which cause kidney damageand blindness. They may also cause heartfailure. 8. Diabetes: Type 1 Insulin Dependentdiabetes It is a condition where the pancreas does not make enough of the hormone insulin. Insulin is necessary to control the level of sugar (glucose) in the blood. 9. Glucose is excreted by the kidneys, leaving little in the body for energy production. If the blood sugar level rises or if it falls the patient may become weak and may lapse into a coma. 10. Pancreas 11. Type 2 non insulin dependent This type occurs in older people who are likely to be overweight. The pancreas makes insulin but the insulin does not work. This form of diabetes may be helped by losing weight and/or following a diabetic diet. 12. SymptomsExcessive thirstIncrease in the amount of urine excretedWeight lossTiredness 13. Treatment Follow low-sugar diet Eat high-fibre/starchy foods Eat regularly never go long without food Artificial sweeteners may be used to replacesugar Special diabetic foods,e.g. jam,chocolate,can beincluded in the diet Lose weight if necessary. 14. Medical Treatment In mild cases,diabetes can betreated by dietalone. However, manydiabetics need dailyinjections of insulin. 15. Coronary Heart Disease It occurs when the mainarteries of the heart becomehard and blocked with a fat-like substance calledcholesterol this narrows thediameter of the vessels andprevents blood from flowingfreely so that blood pressurerises. Eventually an artery maybecome totally blocked,causinga heart attack. In a similarway, blockage of an artery inthe brain causes a stroke. 16.

High Fibre diet Dietary fibre is found only in plant foods. It consists mainly of cellulose, which formsthe structural framework of the plant. It is most plentiful in the outer skin ofvegetables and fruit and the husk of cereals. Fibre is not digested but helps to move thefood along by creating bulk in the intestine. 24. Benefits of a high fibre diet Fibre prevents constipation Prevents poisonous chemicals frombuilding up in the body Fibre does not contain calories but it givesa feeling of fullness.

Refined food In the past, because fibre was consideredto be rough on the intestines,manufacturers began to refine orprocess the food. Processing removesthe outer layers from cereals etc. so thatthere is little fibre left. Processing alsoremoves valuable minerals and vitamins,particularly vitamin B. For these reasonsunprocessed foods are nowrecommended 28.
