when should you seek medical advice about metabolic syndrome
if you have 1 of the 4 components its important to test for the others so you know if you have metabolic syndrome or not
3 ways to prevent metabolic syndrom
- Commit to a healthy diet
- get moving: 30 min per day of moderately strenuous activity on most days of the week
- schedule regular check-ups
how to diagnose metabolic syndrom
- Waist circumference: >35in in women, >40in in men
- triglyceride: levels of 150mg/dl or higher
- blood pressure: 130/85mmHg or higher
- Fasting blood glucose: level of 110mg/dl or higher

people who have metabolic sydrome often have 2 other problems that can either cause the condition or make it worse, what are they
- excess blood clotting
2. low levels of inflammation throughout the body
what is the primary target of therapy for metabolic syndrome
insulin resistance
what are you trying to prevent with the treatment of metabolic syndrom
- type II diabetes
- heart attack
- stroke
what is the treatment to reduce the insulin resistance in overweight and obese individuals
an aggressive regimen of self care strategies focusing on diet and exercise
what components does your doctor routinely monitor to see if lifestyle changes are workin
- weight
- blood glucose
- cholesterol
- blood pressure
how can insulin resistance be controlled
- losing 5-10% of your body weight
- exercise for at lease 30 minutes per day
- stop smoking
- eat fiber rich foods
what types of medications can control metabolic syndromes individual risk factors
- weight loss drugs (meridia, xenical)
- insulin sensitizers (metformin)
- aspirin
- medications to lower blood pressure
- medications to regulate cholesterol
who is less likely to develop metabolic syndrome
middle aged men with moderate PA and C-V fitness
how much exercise does CDC-ACSM recommend for all adults to engage in to prevent chronic diseases
30 min per day
between the years 1986-2001 the prevalence of metabolic syndrome in 24 y/os was found to have increased in what country
finland
most studies have found that metabolic syndrome is inversely associated with what
physical activity or physical fitness
what is the general definition of diabetes
diabetes is the impairment of metabolization of carbs, fat, and protein due to insufficient secretion of insulin or insulin resistance
what do the A1c test results mean?
how much glucose is bound to hemoglobin
for a person without diabetes, what are the typical A1c result levels
about 5%
what are the A1c test results if you are prediabetic
5.7-6.3%
what are the A1c test results if you have diabetes
6.5% or above
at what age does the American Diabetes Association recommend taking the A1c
age 45 if you are overweight or obese and repeated every 3 years
what is Type I diabetes
insulin dependent
- body lacks or has no insulin production
- abrupt onset of symptoms
- usually diagnosed in children or young adults and was previously known as juvenile diabetes
what age does Type I diabetes typically occur in males and females
females: age 5-6
males: age 10-14
what is type II diabetes
non-insulin dependent
1. the body does not produce enough insulin or the body ignores the insulin produced
why is insulin necessary for the body
necessary for the body to be able to use glucose to produce energy
1. When you eat food, the body breaks down all of the sugars and starches into glucose, which is the basic fuel for the cells in the body. Insulin takes the sugar from the blood into the cells. When glucose builds up in the blood instead of going into cells, it canlead diabetic complications.
what populations are affected by type II diabetes
- individuals above the age of 40
2. more common in AA, latinos, Natives, asian, native hawaiians, and pacific islanders
what is gestational diabetes
high blood sugar levels during pregnancy
1. possibly due to hormones from the placenta impairing the action of the mothers insulin
how does gestational diabetes affect the fetus
causes a condition called macrosemia (large and heavy baby)
for how long has diabetes been considered a deadly disease
2,000 years
when was the distinction between type I and type II determined?
1935
what are the classic signs of type I diabetes
- frequent urination
- unusual thirst
- extreme hunger
- unusual weight loss
- extreme fatigue and irritability
what are the classic signs of type II diabetes
- any of the type I symptoms
- frequent infections
- blurred vision
- cuts/bruises that are slow to heal
- tingling or numbness in the hands/feet
- recurring skink gum, or bladder infections
what are the causes of the following diabetes symptoms
- frequent urination
- unusual thirst
- weight loss
- exhaustion
- numbness
- Frequent Urination- Stems from a lack of insulin
- Unusual Thirst- Goes hand in hand with urination
- Weight loss- The pancreas stops making insulin, therefore the body looks for an energy source other than glucose
- Exhaustion- Not enough glucose for energy
- Numbness or Tingling (Neuropathy)- Glucose destroys the nervous system, particularly affects the extremities
what are the 3 known risk factors for type I diabetes
- family history
- genetics
- geography
what are the 3 possible risk factors for type I diabetes
- viral exposure
- low vitamin D levels
- other dietary factors
what are the know risk factors for type II diabetes
- impaired glucose tolerance or impaired fasting glucose
- people over age 45
- family history
- overweight
- no regular exercise
- low HDL and high blood pressure
- racial and ethnic groups
- women who had gestational diabetes
what is the etiology of Type I diabetes
- environmental trigger
- immune system attacks pancreas beta cells
- insulin production decrease
etiology of type II diabetes
- insulin release depressed after a meal
- insulin resistance
- fewer insulin receptors on cells (down regulations)
- associated with obesity and pregnancy
etiology of gestational diabetes
high blood sugar levels in pregnant women who have never had diabetes
-hormones block insulin from doing its job
what percent of 20+ year old people have pre-diabetes
35%
epidemiology of men and women over 20 with diabetes
- 8% men
10. 8% women

2-10%
what percent of post pregnant women develop type II
5-10%
for individuals who have diabetes, what other diseases are they now more prone to develop?
- Heart disease 2-4x more likely
- stroke risk 2x more likely
- hypertension 2/3 of 20+years
- diabetic retinopath 28.5% of 40+
- kidney failure 44%
- nervous system damage 60-70%
- ampuations 60%
- dental disease 2x more likely
people who have a blood glucose level above 250mg/dl are not recommended to work out. why?
because they do not have insulin to break it down and working muscles would require more glucose so the body would release more making the blood glucose levels to rise even more
what reduces the risk of diabetes by 58%
losing weight and increase in physical activity
by what percent does the drug metformin reduce the risk of diabetes
31%
if fasting glucose drops b 1% how does that help?
leads to a 40% drop in eye, kidney and nerve issues
if blood pressure drops 10mmHg how does that help
leads to 12% decerased risk for complications
if you have control of LDL levels how does that help
leads to 20-50% reduction in cardiovascular problems
what are the goals of diabetes treatment
- Minimize the elevation of blood glucose levels
- Avoid causing any abnormally low blood glucose levels
- Reduce weight/body fat (especially those with type II diabetes)
- Increase sensitivity to insulin
- Improve overall health and fitness
what are the prescription drugs for type I
insulin injections
