Malfunction in homeostasis Flashcards
what is diabetes type 1
occurs when insulin production fails (some cant produce glucagon either) and therefore are unable to take up glucose from the bloodstream
what causes type 1 diabetes
when the bodies immune system destroys beta cells in the pancreas ( those cells that produce insulin)
what can type 1 diabetes lead to
an insulin deficiet which can lead to hyperglycaemia or hypoglycaemia.
what is hyperglycaemia
because people with type 1 diabetes cant absorb glucose. Hyperglycaemia is the state of having blood glucose levels above the normal range (>7.8 mmol/L)
what is hypoglycaemia
Hypoglycaemia occurs when blood sugar levels drop below 4.0 mmol/L
what causes hypoglycaemia
inject too much insulin, or if they exercise too much or don’t consume enough glucose. when alpha cells are impaired, people with type 1 diabetes don’t produce normal levels of glucagon, meaning that they do not produce normal amounts of glucose via glycogenolysis in periods of fasting and their blood glucose level continues to fall.
what is hyperthyroidism
Hyperthyroidism is a condition caused by an overactive thyroid gland. As a result, increased amounts of thyroid hormones (thyroxine and triiodothyronine) are secreted into the body, causing an increased metabolism
