While reading the page on metabolic pathways, it interesting to see the visual of how interconnected and delicate that these metabolic pathways truly are. During my time as a biology student, I have had the opportunity to study many of the different reactions independently of each other. Unfortunately, due to this style of learning during this time I did not see how interwoven these pathways are with each other. This interconnectedness of various metabolic pathways makes sense when you think of diseases being caused by a seemingly unrelated hormone or chemical that is too high or too low in another part of the body. It shows how a tiny imbalance in one system can cascade into a serious problem for another system.
Diabetes is one of the most prevalent
and common illness in the United States that is caused by an imbalance in the
metabolic pathways of our body. I do not think there is anyone in the class or
country that does not personally know an individual who has either Type I or
Type II diabetes. From previous knowledge, I know that Type I is a genetic
defect where the body is unable to produce insulin, and that Type II happens
after the body is unable to effectively take up glucose. It is interesting to
look at how different organ systems play roles in controlling blood sugar and
hyper or hypoglycemia. The major hormones that are involved in this is the
pathway are insulin and glucagon. They are antagonists of each other meaning
they have opposite effects when secreted. While reading the slide about how
insulin is used to properly uptake glucose, it talks about when the body does
not have the proper amount of insulin it is unable to use the glucose. The
slide says, “cells essentially starve in the midst of plenty of sugars.” While
reading this I could only think of the people who are unfortunately apart of a shipwreck
and while stranded at sea they pass away from dehydration. Even though they are
surrounded by water, they are unable to drink it because their bodies and
especially the kidneys cannot filter that high salt level. This is the same way
our bodies reacts when we have had a diet high in sugar for extended periods of
time. Our receptors to insulin become worn out and our bodies are unable to
breakdown and use glucose. The cells starve in an environment that has all it
needs to sustain life they are just unable to use it.
Diabetes can also cause damage to
many different systems. Many healthcare providers are aware of the different
forms that diabetic damage can manifest in the body. While shadowing at an
ophthalmology clinic, I saw how when a patient came in for their check up the
ophthalmologist would be significantly more thorough with their checkups if the
patient had a history of diabetes. This is because diabetes would increase
their chance of getting cataracts early in life or could severely damage the
blood vessels in the retina or the back of the eye. This is called diabetic
retinopathy and is one of the leading causes for blindness in the developed
world among adults. The damage to these blood vessels in many cases are permanent.
Early diagnosis and treatment of diabetic retinopathy are the only way to
prevent blindness. Many patients would come into the clinic and have none to
mild symptoms of diabetic retinopathy because they were good at controlling
their A1C and blood sugar levels. Others had serious complications because they
were unable to make the needed changes to their lifestyle and diet to control
their diabetes.
While reviewing diabetes, I was
shocked to find that diabetes was among the top ten leading cause of death in
2013. I decided to find some more recent data because we have seen obesity
rates climb in recent years and obesity has a strong correlation with diabetes.
According to the Centers for Disease Control, or CDC, in 2022 diabetes was the
eighth leading cause of death in the United States with just over a hundred
thousand deaths. This fell from the seventh place that it was in not because of
better life decisions and dieting but because of COVID-19. Many of the highest
listed diseases could all be simplified down to inactive lifestyle and poor
diets. As Americans, we love to use our cars and drive wherever we want to go
even if it is just down the street. This means that we are missing out on
simple exercises that many other countries are gaining. The United States has a
car ownership of 900 cars per thousand people. Japan on the other hand has only
800 per thousand individuals. In 2021, Japan also had only fourteen thousand
deaths due to diabetes. Diabetes as a cause of death is not even in the top 20
causes of death but is ranked at 25. It is presumptuous to say that one element
like driving cars all the time is the primary cause of diabetic deaths, but it
is fair to say that many different things are coming together to cause an epidemic
in the United States. This is impacting our economy in a major way. In 2012,
the cost of diabetes and the strain it puts on the United States was estimated
at $245 billion but according to the National Institutes of Health in 2022 it was
up to $413 billion. This is $4 billion more than the GDP of Vietnam, a country
that is home to almost 100 million people. This is a serious strain on our
government who pays for a lot of Medicare and Medicaid. Diabetic ailments also crowd
the hospital system with patients who could have avoided many of the issues if
they changed their lifestyle. There needs to be a more cost effective treatment
and it starts with proper education on individuals’ health.
Diabetes
also does not affect individuals in varying socioeconomic levels equally also.
Many who come from poor areas of the country have the highest risk of obesity
and diabetes. If you overlay the maps of average income and levels of obesity
it almost mirrors each other. This is because the more affluent individuals
have the ability to buy fresh produce and have disposable income to spend on
gyms and trainers. These factors help reduce their risks of developing type II
diabetes. But the individuals who are poor often can only afford to eat fast
food or prepared and highly processed snacks. These individuals live in areas
called food deserts. This means that making it to a store to buy fresh produce
is unobtainable due to how far of travel it is to the grocery store. We can see
that in the stores it is cheaper to buy soda than it is to buy real fruit
juices and healthy option drinks. Many families choose the unhealthy options
and increase their risk of diabetes and other obesity linked diseases.
A very well written and informational post thank you. I liked how you mentioned the correlation between poverty, access to nutritious food, and diabetes risks. I also liked how clearly you explained the information and made it easy to understand what you were trying to say.
