The human body is very complex and seeks to maintain a constant internal environment. This state of dynamic equilibrium is called homeostasis. Some diseases such as diabetes can impact the body’s ability to maintain homeostasis. To maintain a relatively constant internal environment, the human body uses negative and positive feedback
As a medical professional, how would you explain the role negative and positive feedback plays in maintaining homeostasis to a newly diagnosed diabetic patient?
The sources you use for your posts and papers must be scholarly in nature. This means that you should use peer-reviewed journal articles, credible texts, and only certain websites. Like “.gov” and “.edu” websites are usually credible. For “.gov” websites, please make sure that the information is still relevant.
For “.edu” websites, do not use student published webpages as sources of information.
All other websites (e.g., “.com,” “.org,” “.net” etc.) should not be used as credible sources of information.
Some “.org” websites may be used if information is not biased and there is a clear reason to include this organization in your work.
For scholarly works, such as your projects, most of your sources should be peer-reviewed journal articles.
DO NOT USE MAYO CLINIC, WEBMD, OR OTHER WEBSITES WITH ADVERTISEMENTS AS SOURCES.Find quailty works to base your ideas on!

Homeostasis is a state of dynamic equilibrium that the human body maintains to function properly. Negative and positive feedback mechanisms play a crucial role in maintaining homeostasis. In this context, the following answer will explain the role of negative and positive feedback in maintaining homeostasis to a newly diagnosed diabetic patient.
As a newly diagnosed diabetic patient, it is fundamental to understand how negative and positive feedback maintains the body’s homeostasis. Negative feedback is a natural mechanism that helps to stabilize the body’s internal environment. For instance, when glucose levels rise in your blood, the pancreas releases insulin. Insulin promotes the absorption of glucose by cells to produce energy, thus stabilizing the blood glucose levels. A decrease in glucose levels inhibits insulin secretion, preventing the blood sugar levels from dropping too low.
On the other hand, positive feedback is a mechanism that amplifies or enhances a change in the body. It is not used to maintain homeostasis but to intensify a process. For example, during childbirth, contractions increase in frequency and strength due to a positive feedback loop until the baby is born.
In summary, negative feedback is essential in maintaining homeostasis, while positive feedback intensifies biological processes. Understanding these mechanisms can help a newly diagnosed diabetic patient realize how insulin secretion maintains glucose balance, which is crucial in managing diabetes. Therefore, it is crucial always to consider credible sources when seeking information to manage diabetes effectively.
