In healthy men and women, urine does not contain any blood that can be seen with the eye, called "gross blood," nor does it contain red blood cells that can be discovered with the aid of a microscope. The discovery of either gross or microscopic blood in urine is a sure indication of the need to examine and evaluate the patient to discover the cause of this abnormality. The conditions that can lead to either gross or microscopic blood in the urine are many and varied. In adults, a careful history to describe the details of the bloody urine, a physical examination and laboratory studies are the first step in unearthing the cause. Imaging with x-rays, ultrasound, CAT/MRI scans are the next step and will usually discover the cause. In adult women, infection of the bladder or kidneys, urinary stones, and tumors of the urinary bladder, kidneys are the most common causes. In adult men, enlargement and/or infection of the prostate, bladder infection and...

Skeletal muscle ischemia (blood deficiency)
Skeletal muscle trauma
About a month ago I had my first endocrinologist appointment since well before Mateo was born. During the pregnancies, my perinatologist (high-risk OB) took care of all of my diabetes management with a focus on tightly controlled blood sugars. In the weeks leading up to the endo appointment, I'd had a couple epiphanies I was looking forward to acting on.
First of all, I noticed that the blood glucose range I'd unconsciously been striving for was probably too restrictive for a non-pregnant diabetic. All the years of trying to keep my blood glucose level between 70-140 mg/dl had really skewed my perception of what constituted a "high" blood sugar. For instance, I would get a result of 150 mg/dl and correct it, which often led to lows. It dawned on me one day, "I don't have to correct for a 150 mg/dl!"
This led me to another revelation: if I'm able to keep my blood sugar steady within a slightly wider range of blood suga...
