Osteoporosis and Diabetes Flashcards
Osteoporosis
- Low bone mass and structural deterioration of bone tissue
- Bone fragility/ increased susceptibility to fractures,
Symptoms of Osteoporosis
- Bones become weak, sudden strain, bump or fall causes a fracture or collapse in vertebrae
- Loss of height, spinal deformities (kyphosis) and severe pain
Type 1 Osteoporosis
- Occurs primarily in women aged 45-60 years (postmenopausal), associated with oestrogen depletion
- First 5-7 years women can lose as much as 20% of their bone mass
Type 2 Osteoporosis
- Occurs in males and females over 70 years
- Associated with low bone mass and the ageing
Bone Remodelling
- Bone is constantly being broken down and replaced with new bone tissue.
- With age more bone is broken down than is replaced.
Osteoclasts
Breakdown old bone
Osteoblasts
Replaces old bone with new tissue. Which then mineralises.
Stages of Osteoporosis
- Bone building
- Osteopenia
- Osteoporosis
Bone Building
From childhood to early adulthood (diet rich in Ca and vitamin D; weight bearing exercise)
Osteopenia
- Evidence of reduced bone mass is detected (stooped posture).
- Can be treated through lifestyle change and medication
Osteoporosis
- Bone loss is unmistakable (bone mineral density test).
Osteoporosis Causes
- Smoking
- Sedentary lifestyle
- Family history (Genetics)
- Heavy drinking
Nutrition (Osteoporosis)
- Adequate intake of Calcium and Vitamin D
- Avoid heavy drinking and smoking as it inhibits calcium absorption
Oestrogen Deficiency
- Stronger stimulus for bone loss than Calcium deficiency
- Oestrogen influences bone three times as much as exercise
Diabetes
- Body’s production and use of insulin is impaired
- Causes sugar to build up in the blood stream
Glucose
Main source of energy for the body. It is the only fuel source for brain cells
Insulin
Hormone secreted by the pancreas. It stimulates cells to absorb glucose
Metabolic Disorder
- The body cannot metabolise carbohydrates properly, leads to high levels of glucose in the blood.
- The body then switches to fats and proteins as an energy source.
Type 1 Diabetes
- Elevated blood glucose levels come from insufficient insulin production
- Insufficient insulin production keep body cells “locked”
- Glucose cannot be used as fuel source
Type 2 Diabetes
- Elevated blood glucose results from cells becoming unresponsive to existing insulin.
- Age, family history, obesity & sedentary lifestyle (risk factors)
Flash Glucose Monitering
- Small disposable glucose
sensor worn on the skin for up
to 14 days - Wireless reader device/smartphone with app
- Does not replace blood glucose
monitoring
Hypoglycaemia (Insulin Shock)
- Low blood sugar levels.
- Caused by too much circulating insulin or too little food to balance insulin.
Symptoms
* Uneasy
* nauseated
* Uncoordinated
Hyperglycaemia (Diabetic Coma)
- Excess of glucose in the bloodstream
- Too little insulin available to fully metabolise carbohydrates.
