One of the ways that increased stress can play a role in brittle diabetes would be because it can cause the body to have a temporary and extremely strong resistance to insulin. Naturally, this means the body will not react to insulin in the correct manner. To exacerbate the problem, patients often will have sudden flare-ups that will often occur without warning. Thus, high amounts of stress can cause diabetes patients to not be able to accurately judge how much insulin they need. What is the solution to preventing stress-induced brittle diabetes? It's simple, really. Patients should try to find some ways to manage their stress better. Although it can be difficult to change one's mindset, it can definitely help patients prevent brittle diabetes from occurring due to stress.
