When insulin removes excess sugar from the blood, it sends it to the kidneys. Researchers at Johns Hopkins University found that the kidneys have a special way of draining sugar from the blood. This drain sends sugar that isn't needed into the urine.
If everyone has this organelle, why do some people have trouble controlling their blood sugar levels after eating the same amount of carbs as others?
Sometimes, it could be because the body doesn't respond well to insulin. Sometimes, it could be because insulin doesn't work as well as it should.
Usually, it's not. A protein made by the body stops this blood sugar drain.
This protein looks like sticky grey mucus and blocks the blood sugar filters in the kidneys. This makes it hard for the natural blood sugar drain to work.
