Thirst, Frequency And Blurry Vision……early Signs Of Diabetes?
Excessive thirst, increased urinary frequency and blurry vision can all be early signs of undetected diabetes mellitus. What you already know. Diabetes mellitus is the body’s inability to decrease the sugar in the blood. This “serum glucose” rises after every meal as our food is broken down into its basic components. In the normal situation, a rise in blood sugar causes insulin to be secreted into the blood stream. Insulin takes blood sugar out of the blood and delivers it to our tissues. As a result, serum glucose levels are kept low and maintained at a steady state. If insufficient insulin or no insulin is produced, then the sugar remains in the blood stream and the sugar level rises. High levels of sugar increase the “osmolarity” of the blood. Osmolarity is a difficult term to understand, but it reflects the ability of a substance to attract water. The higher the osmolarity of a liquid, the more water it will attract and retain. In this case, as the serum glucose increases, it will literally draw water out of our tissues. We feel thirsty because our tissues are actually dehydrated, hence the increased thirst. The increased water in our blood then causes more urination. Continue reading >>
