Diabetes Mellitus
an endocrine disorder associated with abnormally high levels of glucose in the blood
happens because pancreas does not produce enough insulin or the insulin produced is ineffective
many body cells rely on insulin to attach to them in order to allow glucose to enter from blood so cells can be supplied with energy
if glucose remains in blood the body will metabolise fats and proteins for energy instead
high concentration of glucose in the blood can cause blindness / vision impairment, and kidney failure
TYPES
type 1 (insulin-dependent {IDD})
type 2 (non-insulin-dependent {NIDD})
TYPE 1
pancreas does not produce insulin
often hereditary and develops mainly during childhood, adolescents and young adulthood
controlled by injectable insulin, diet and exercise
cannot be reversed
TYPE 2
pancreas produces insulin
that cannot be used by body
develops mainly during late adulthood, especially among overweight adults
HYPERGLYCAEMIA
blood sugar level rises
happen if take too little insulin or too many carbs
insulin intake required to prevent diabetic coma
symptoms - tiredness, excessive thirst, and frequent urge to urinate
HYPOGLYCAEMIA
blood sugar level drops
happen if take too much insulin or too little carbs
glucose intake required to prevent diabetic coma
symptoms - paleness, blurred vision, and dizziness
DIETARY GUIDELINES
controlled by oral medication or injectable insulin and diet and exercise, or diet and exercise alone
can be reversed when a person loses a significant amount of their body weight
maintain healthy weight by reducing intake of foods high in saturated fat (especially for type 2)
increase intake of high-fibre foods as they release glucose slowly and steadily
choose diabetic confectionary to avoid glucose levels spiking
choose low glycaemic index (GI) foods as they release glucose slowly and steadily eg: porridge
regular, balanced meals to
avoid hyperglycaemia or hypoglycaemia
